#supercapacitor
Two of humanity's most ubiquitous historical materials, cement and carbon black (which resembles very fine charcoal), may form the basis for a novel, low-cost energy storage system, according to a new study. The technology could facilitate the use of renewable energy sources such as solar, wind, and tidal power by allowing energy networks to remain stable despite fluctuations in renewable energy supply. The two materials, the researchers found, can be combined with water to make a supercapacitor -- an alternative to batteries -- that could provide storage of electrical energy. As an example, the MIT researchers who developed the system say that their supercapacitor could eventually be incorporated into the concrete foundation of a house, where it could store a full day's worth of energy while adding little (or no) to the cost of the foundation and still providing the needed structural strength. The researchers also envision a concrete roadway that could provide contactless recharging for electric cars as they travel over that road. The simple but innovative technology is described in a forthcoming paper in the journal PNAS, in a paper by MIT professors Franz-Josef Ulm, Admir Masic, and Yang-Shao Horn, and four others at MIT and at the Wyss Institute.

Electrolyte Anti-penetration Absorption Material, SINOYQX Melamine Foam
What is electrolyte?
Electrolyte is the medium used in chemical batteries, electrolytic capacitors, etc., and its representative content varies greatly in different industries. There are electrolytes in living organisms (also called electrolytes), there are also electrolytes used in the battery industry, as well as electrolytes in electrolytic capacitors, supercapacitors, and other industries.
Tumblr media
The compositions of electrolytes used in different industries vary greatly, or are even completely different. For example, the human body's electrolytes are mainly composed of water, sodium chloride, pH buffering substances, etc.; the electrolyte of aluminum electrolyte capacitors contains major solvents such as GBL; the supercapacitor electrolyte contains propylene carbonate or acetonitrile as the main solvent; the electrolyte of lithium manganese primary battery contains main solvents such as propylene carbonate and ethylene glycol dimethyl ether;  lithium-ion battery electrolyte contains main solvents such as ethylene carbonate, dimethyl carbonate, ethyl methyl carbonate and diethyl carbonate. Their respective conductive salts are also completely different, such as sodium chloride in the human body, tetraethylammonium tetrafluoroborate in the supercapacitor electrolyte, and lithium perchlorate or lithium triflate commonly used in lithium manganese primary batteries. And in lithium-ion batteries, it is lithium hexafluorophosphate.
There are many advantages to using electrolyte as a cathode. The first is that the contact area between the liquid and the medium is large, which is helpful to increase the capacitance. Secondly, electrolytic capacitors made with electrolyte can withstand high temperatures, so they can pass wave soldering (wave soldering is an important process for SMT patch installation), and they also have relatively strong voltage resistance. However, the electrolyte also has shortcomings, and there are potential safety hazards, such as environmental pollution, fire, and human injury caused by leakage.
What are the dangers of electrolyte leakage?
1. Inhalation hazards
Fine gas suspensions in the electrolyte are easily mixed into the atmosphere. Especially when the temperature rises, the poisonous gas in the electrolyte is easily inhaled, which can cause neurotoxicity in the human body. Lithium battery electrolyte can cause respiratory, eye, and skin irritation, with symptoms including cough, diarrhea, headache, blindness, and skin burning.
2. Skin contact hazards
When a large amount of gas is released, the electrolyte is easy to splash out and meet the skin, which can cause skin burns, irritation, and allergic skin diseases. It can even cause severe tissue fragmentation and coagulation, skin whitening, blisters, irritating eczema and ulcerated dermatitis symptoms.
3. Risk of eye contact
The electrolyte can not only pass through the skin, but also stick along the facial skin and into the eyes. If not treated in time, it can cause further damage to the retina and eye membranes, and cause symptoms such as pain, irritation, eye warmth, tearing, eye itching, and itching.
4. Dangers of dietary intake
When improperly maintained, the electrolyte of the electrolyte splashes into food, which can cause harmful substances such as ions, acids, alkali impurities, and heavy metals in the liquid to contaminate food and water sources. These substances have an extremely serious impact on human health and can cause symptoms such as nausea, vomiting, general discomfort, stomach pain, gastrointestinal soreness, and even death.
5. Flammability hazards
If there is contamination or large amounts of leakage, flammable gases can easily form. Once a fire occurs, the lithium battery electrolyte flame will become violent and the fire will accelerate significantly, increasing the disaster.
6. Environmental pollution hazards
The discharge of electrolyte not only damages the environment, but also affects the fertility of the soil. And it cannot be decomposed, even if it is affected by natural degradation in the atmosphere and water, it will remain in the surface soil and water. Long-term contamination of land and water sources may also pose potential threats to human health.
How to prevent electrolyte leakage?
The use of anti-penetration absorbent materials can effectively prevent electrolyte leakage. Melamine foam, for example, can be used to absorb leaked electrolyte after the adapter's electrolytic capacitor fails to avoid safety issues such as power short circuit caused by electrolyte.
Excellent properties of melamine foam anti-penetration absorbent material:
1) 10 times liquid absorption performance
2) Excellent liquid storage performance
3) Long-term insulation performance and anti-static performance
4) Excellent acid and alkali resistance, corrosion resistance
5) Anti-mildew, anti-UV
6) Wide operating temperature, -196 degrees ~ 200 degrees
7) Melamine foam is non-fibrous material, does not contain any dust, does not contain any halogenated hydrocarbons, flame retardants or toxic heavy metals
Applicable Products:
Lithium batteries, supercapacitors, charging adapters, mobile electronic devices, energy storage systems, power batteries, sodium-ion batteries, etc.

New study finds 'sweet spot' for length of yarn-shaped supercapacitors
As interest in wearable technology has surged, research into creating energy-storage devices that can be woven into textiles has also increased. Researchers at North Carolina State University have now identified a "sweet spot" at which the length of a threadlike energy storage technology called a "yarn-shaped supercapacitor" (YSC) yields the highest and most efficient flow of energy per unit length. "When it comes to the length of the YSC, it's a tradeoff between power and energy," said Wei Gao, corresponding author of a paper on the work published in the Journal of Power Sources and an associate professor of textile engineering, chemistry and science at NC State. "It's not only about how much energy you can store, but also the internal resistance we care about." Specifically, the researchers found that YSCs in the 40–60 centimeter range provided the best overall energy output.

Super Capacitor Manufacturers Explain the Development History of Super Capacitors for You
https://www.kamcappower.com/super-capacitor-manufacturers-explain-the-development-history-of-super-capacitors-for-you.html
Tumblr media
Supercapacitors are electrochemical components developed from the 1970s and 1980s that use polarized electrolytes to store energy. It is different from the traditional chemical power supply. It is a power supply with special performance between traditional capacitors and batteries. It mainly relies on an electric double layer and redox pseudocapacitor charge to store electric energy.
 In 1879, Helmholz discovered the properties of double-layer capacitors and proposed the concept of electric double layers, but the use of electric double layers for energy storage is only a matter of recent decades. In 1957, Bcker first proposed that a smaller capacitor can be used as an energy storage device, which has specific energy close to that of a battery. In 1968, Standard Oil Corporation Sohio first proposed a patent for making double-layer capacitors using high-specific surface area carbon materials and transferred the patented technology to NEC. NEC began to produce supercapacitors for the start-up system of electric vehicles in 1979.
 As a product, supercapacitors have become mature, and their application scope has been continuously expanded. They have been widely used in industries, consumer electronics, communications, medical equipment, national defense, military equipment, and transportation. From small-capacity special energy storage to large-scale electric energy storage, from separate energy storage to hybrid energy storage combined with batteries or fuel cells, supercapacitors have demonstrated unique advantages. The United States, Europe, Japan, South Korea, and other developed countries and regions have conducted fruitful research on the application of supercapacitors.
 JINZHOU KAIMEI POWER CO., LTD is one of the most professional supercapacitor manufacturers in China. It is the eternal goal of JINZHOU KAIMEI POWER CO., LTD to build the best supercapacitors and establish a world-class supercapacitor manufacturing company. Welcome everyone to cooperate with us!

New Carbon Material Sets Energy-Storage Record, Likely to Advance Supercapacitors - Technology Org
New Post has been published on https://thedigitalinsider.com/new-carbon-material-sets-energy-storage-record-likely-to-advance-supercapacitors-technology-org/
New Carbon Material Sets Energy-Storage Record, Likely to Advance Supercapacitors - Technology Org
Guided by machine learning, chemists at the Department of Energy’s Oak Ridge National Laboratory designed a record-setting carbonaceous supercapacitor material that stores four times more energy than the best commercial material.
A supercapacitor made with the new material could store more energy — improving regenerative brakes, power electronics and auxiliary power supplies.

“By combining a data-driven method and our research experience, we created a carbon material with enhanced physicochemical and electrochemical properties that pushed the boundary of energy storage for carbon supercapacitors to the next level,” said chemist Tao Wang of ORNL and the University of Tennessee, Knoxville.
Wang led the study, published in Nature Communications, with chemist Sheng Dai of ORNL and UTK.
“This is the highest recorded storage capacitance for porous carbon,” said Dai, who conceived and designed the experiments with Wang. “This is a real milestone.”
The researchers conducted the study at the Fluid Interface Reactions, Structures and Transport Center, or FIRST, an ORNL-led DOE Energy Frontier Research Center that operated from 2009 to 2022. Its partners at three national labs and seven universities explored fluid-solid interface reactions having consequences for capacitive electrical energy storage. Capacitance is the ability to collect and store electrical charge.
When it comes to energy storage devices, batteries are the most familiar. They convert chemical energy to electrical energy and excel at storing energy.
By contrast, capacitors store energy as an electric field, akin to static electricity. They cannot store as much energy as batteries in a given volume, but they can recharge repeatedly and do not lose the ability to hold a charge. Supercapacitors, such as those powering some electric buses, can store more charge than capacitors and charge and discharge more quickly than batteries.
Commercial supercapacitors have two electrodes — an anode and cathode — that are separated and immersed in an electrolyte. Double electrical layers reversibly separate charges at the interface between the electrolyte and the carbon. The materials of choice for making electrodes for supercapacitors are porous carbons. The pores provide a large surface area for storing the electrostatic charge.
The ORNL-led study used machine learning, a type of artificial intelligence that learns from data to optimize outcomes, to guide the discovery of the superlative material. Runtong Pan, Musen Zhou and Jianzhong Wu from the University of California, Riverside, a FIRST partner university, built an artificial neural network model and trained it to set a clear goal: develop a “dream material” for energy delivery.
The model predicted that the highest capacitance for a carbon electrode would be 570 farads per gram if the carbon were co-doped with oxygen and nitrogen.
Wang and Dai designed an extremely porous doped carbon that would provide huge surface areas for interfacial electrochemical reactions. Then Wang synthesized the novel material, an oxygen-rich carbon framework for storing and transporting charge.
The carbon was activated to generate more pores and add functional chemical groups at sites for oxidation or reduction reactions. Industry uses activation agents such as potassium hydroxide that require a very high temperature, around 800 degrees Celsius, which drives oxygen from the material.
Five years ago, Dai developed a process using sodium amide as the activation agent. It works at a lower temperature, near 600 degrees Celsius, and creates more active sites than the hotter industrial process. “Material synthesis in this ‘Goldilocks zone’ — not too cold, not too hot — made a real difference in not decomposing the functional groups,” Dai said.
The synthesized material had a capacitance of 611 farads per gram — four times higher than a typical commercial material. Pseudocapacitance is storage of charge based on continuous, fast and reversible oxidation-reduction reactions at the surface of electrode materials.
Pseudocapacitance from such reactions at the oxygen/nitrogen sites contributed to 25% of the overall capacitance. The material’s surface area was among the highest recorded for carbonaceous materials — more than 4,000 square meters per gram.
This success came quickly. The data-driven approach allowed Wang and Dai to achieve in three months what would have previously taken at least a year.
“We achieved the performance of carbon materials at the limit,” Wang said. “Without the goal that machine learning set, we would have kept optimizing materials through trial and error without knowing their limit.”
The key to success was achieving two kinds of pores — mesopores between 2 and 50 nanometers, or billionths of a meter, and micropores tinier than 2 nanometers. In experimental analyses, the chemists found that the combination of mesopore and micropores provided not only a high surface area for energy storage but also channels for electrolyte transport.
Miaofang Chi and Zhennan Huang at the Center for Nanophase Materials Sciences, a DOE Office of Science user facility at ORNL, performed scanning transmission electron microscopy to characterize the mesopores, but the micropores were too small to see.
Microscopically, the material looks like a golf ball with deep dimples. The dimples represent mesopores, and the micropores exist in the material between the dimples.
“You are building a highway for ion transport,” Dai said. ”Supercapacitors are all about high-rate performance — fast charging, fast discharging. In this structure that Tao and I designed, you have a larger pore, which you can view as a superhighway. This is connected to smaller roads, or tinier pores.”
“The smaller pores provide a larger surface for storing charge, but the larger pores are like a highway that can speed up the charge/discharge rate performance,” Wang said. “A balanced amount of small and large pores can realize the best performance, as predicted by the artificial neural network model.”
To characterize the electrolyte’s transport in the carbon pores, Murillo Martins and Eugene Mamontov of the Spallation Neutron Source, a DOE Office of Science user facility at ORNL, performed quasielastic neutron scattering. “They tracked the speed on the highway,” Wang said.
“This was the first time that neutron scattering was used to analyze diffusion of a sulfuric acid electrolyte in the confined spaces of carbon nanopores.” Neutron scattering revealed the electrolyte moved at different speeds: quickly in the mesopores and slowly in the micropores.
Wang quantified the capacitance contributions from pores of different sizes and oxidation-reduction reactions at their surfaces via modified step potential electrochemical spectroscopy, a technique that can be done in only a few places in the world. “We found that mesopores doped with oxygen and nitrogen contribute most to the overall capacitance,” Wang said.
The FIRST team performed other studies of the physicochemical properties. Jinlei Cui and Takeshi Kobayashi from Ames National Laboratory used nuclear magnetic resonance to analyze the structure of polymer precursors. Bishnu Thapaliya of ORNL and UTK conducted Raman analysis, revealing the carbon’s amorphous, or disordered, structure.
Zhenzhen Yang of UTK and ORNL and Juntian Fan of UTK participated in the surface area measurements.
This research has the potential to accelerate the development and optimization of carbon materials for supercapacitor applications. Although this breakthrough study used the best data at the time, scientists now have even more boundary data for training the machine learning model for the next study.
”Using more data, we can set a new target and push the boundaries of carbon supercapacitors even further,” Wang said. “The successful application of machine learning in materials design is a testament to the power of data-driven approaches in advancing technology.”
The title of the paper is “Machine-learning-assisted material discovery of oxygen-rich highly porous carbon active materials for aqueous supercapacitor.”
This work was supported as part of the FIRST Center, an Energy Frontier Research Center funded by the DOE Office of Science at ORNL.
UT-Battelle manages ORNL for DOE’s Office of Science. The single largest supporter of basic research in the physical sciences in the United States, the Office of Science is working to address some of the most pressing challenges of our time. For more information, please visit energy.gov/science.
