For the first time, British scientists have turned the waste generated in the process of making coffee into electricity. This research will help farmers in developing countries reduce pollution. It is reported that the world can produce 9.5 million tons of coffee every year, and the coffee industry will produce a large amount of liquid waste in the process of converting coffee beans into coffee. These wastes are generated in the process of cleaning coffee seeds or coffee beans, and intensive water use in the produc

On October 17, the sixth China South Korea Automobile Industry Development Seminar was held in Beijing. The theme of this year's forum is "sharing the experience of hydrogen fuel cell vehicle industrialization and building a hydrogen energy society in Yilai". Hyundai (China) Investment Co., Ltd. and the Ministry of Information Technology and Industry Development of the National Information Center jointly discuss and exchange the development of the hydrogen fuel cell vehicle industry with people from t

According to foreign media reports, Cabot has been selected by the US Department of Energy. The company has participated in a research and development project of advanced vehicle technology and has received some financial support. Cabot will use its innovative processing technology to develop the formula of a new generation of low cobalt active cathode for lithium ion batteries. Cobalt is a key material with high price, which is mainly imported from the United States. With the vigorous development of electric ve

Xia Xinhui, a research team from the School of Materials Science and Engineering of Zhejiang University, has developed the first high-energy density lithium sulfur battery based on mold spore carbon technology. They have introduced mold spore carbon fermented by waste fruits and vegetables into the energy field as energy storage materials, and obtained a high-energy density battery with a specific capacity three times higher than the best battery on the market. It is expected to solve the problem of the endurance o

Challenges faced by hydrogen fuel power cells According to foreign media reports, hydrogen fuel cells may become an important part of sustainable energy in the future. Fuel cells are more like internal combustion engines, because highly efficient hydrogen fuel cells can use reversible electrochemical reactions to generate electricity. The fuel is more environmentally friendly, with only electricity, water and heat generated. Jeongmin Ahn, an associate professor at the College of Engineering and Computer Scien

Dr. Xiong Dejun, deputy director of research and development of New Zebang, delivered a keynote speech on "Development Progress of High Energy Density Power Battery Electrolyte" at the conference. Xiong Dejun said that driven by government subsidies and end-user mileage concerns, high energy density power batteries have become a hot spot in the market. At present, there are three choices for high energy density power batteries: ternary high voltage with graphite, high nickel with graphite, and high nic

Recently, Greenmei (002340), a member enterprise of the G20 Lithium Battery Summit, announced that the company had signed joint venture agreements with Xinzhan International (a subsidiary of Qingshan Iron and Steel), Bangpu Recycling, Molowali Industrial Park in Indonesia, and Sakwa Industrial Co., Ltd. in Ningde, Fujian Province, and planned to invest 700 million US dollars (about 4.8 billion yuan) to set up a joint venture in Indonesia to carry out nickel resource smelting and deep processing and build a manufact

According to foreign media reports, the important problem to be solved in clean energy power generation is energy storage. Scientists are constantly reducing the energy storage cost of the battery, and zinc oxygen air battery seems to be the future development direction. In the past six years, 110 villages in Africa and Asia have received electricity from solar panels and zinc oxygen air batteries. This battery is an important part of an innovative energy storage system developed by Nant Energy. Nant Energy is a

Now we have acquired Dialog, the world's largest power management chip manufacturer. With its power management chips and excellent R&D talent team, we believe that Apple's product safety and endurance will reach a new level in the future. For a long time, the batteries in most of Apple's product lines have been widely criticized, such as the iPhone, apple watch, AirPods, etc., which have not really attracted enough attention from Apple. However, a news recently made the fans have new expectations
