On November 9, as an important part of the 11th China (Hefei) Independent Innovation Elements Matchmaking Conference, the Energy Saving and New Energy Automobile Industry Development Forum was held in Hefei University of Technology. Professor Zhang Tong, an expert on fuel cell vehicles and director of the New Energy Vehicle Engineering Center of Tongji University, was interviewed by Xinhua News Agency on the current status and prospects of fuel cell vehicle research and development in China. According to Zhang T

NEC Corporation of Japan has successfully developed a new technology to increase the power storage capacity of lithium-ion batteries for electric vehicles (EVs) and hybrid electric vehicles by more than 30%. The electric vehicles currently sold on the market can drive about 200 kilometers per charge, and if the newly developed battery is used, the driving distance can be increased to about 260 kilometers. NEC plans to put into practical use within 2 years.(Lithium - Ion Battery Equipment) For a long time, the sh

From smart phones to electric vehicles, lithium-ion batteries (LIBs) provide power for everything. With the progress of technology, lithium-ion batteries have made significant progress and completely changed our world. The next step of technological progress is to develop better batteries to provide more lasting power for electronic devices. A promising technique to improve battery performance involves atomic substitution of positive ions or cations in cathode materials. However, it is complex and expensive to syst

Batteries are widely used in daily applications, such as electric vehicles and electronic devices, and are promising candidates for sustainable energy storage. However, as you may have noticed, when you charge the batteries every day, their storage capacity will decline over time. Eventually, we need to replace these batteries, which are not only expensive, but also deplete the rare earth elements used to make them. One of the key factors to shorten battery life is the degradation of battery structural integrity

On July 16, the State Administration of Market Supervision disclosed the recall information, which showed that Great Wall Motors had filed a recall plan with the State Administration of Market Supervision and Administration in accordance with the requirements of the Administrative Regulations on the Recall of Defective Automobile Products and the Implementation Measures of the Administrative Regulations on the Recall of Defective Automobile Products. It is decided to recall 16216 Great Wall Oula IQ electric vehicle

Toyota announced the research results of the manufacturing process of solid polymer fuel power cell (pEFC) electrodes at the "20th Fuel Power Cell Society of Japan" (held in Tokyo's Furuhiro Tower Hall from May 28 to 29, 2013). Toyota said that with the reduction of the use of platinum (pt) catalyst, the influence of electrode manufacturing process on electrode performance will become more and more obvious. The electrode of fuel power cell is generally made by coating catalyst ink consisting of car

The progress of Li ion batteries has made various portable devices feasible and promoted the development of electronic products. However, the inherent shortcomings of traditional lithium ion batteries, which use liquid electrolyte solutions, make them not completely suitable for electric vehicles and other highly anticipated applications. These limitations include limited durability, low capacity, safety issues, and environmental concerns about their toxicity and carbon footprint. Fortunately, scientists are now fo

In early March, at the 9th International Hydrogen Fuel Cell Exhibition held in Tokyo, Japan, Toyota FCHV adv, Nissan X-TRAIL FCV, Honda FCXClarity and others comprehensively demonstrated the research and development achievements of Japanese FCV (fuel cell vehicle). FCV replaced EV (electric vehicle) as a new highlight of this new energy automobile exhibition, which may indicate that fuel power cell technology will become another development direction of new energy vehicles in the future. On the secondary market, th

Each kind of lithium battery has an optimal charging current value under different state parameters and environmental parameters. From the perspective of battery structure, what are the factors that affect the optimal charging value. Micro process of charging Lithium battery is called "rocking chair type" battery. Charged ions move between the positive and negative electrodes to transfer charge, supply power to external circuits or charge from external power sources. During the specific charging pro
