NawaTechnologies officials said that after the incorporation of carbon nano-supercapacitors, the charging speed of lithium batteries has been significantly improved, and the weight has also been significantly reduced, which can increase cruising range and performance output when applied to electric vehicles. The start-up company in Marseille, France, is developing a new type of battery, which is believed to bring disruptive changes to the traditional electric vehicle industry after its introduction.(Lithium - Ion B

Researchers at the University of Akron have developed Mn3O4/C hierarchical porous nanospheres and used them as anode materials for lithium-ion batteries. These nanospheres have high reversible specific capacity (1237mAh/g when the current is 200?mA/g), excellent stability (425mAh/g when the current is 4A/g) and extremely Long cycle life (current is 4A/g, no obvious capacity decay after 3000 cycles of use). In theory, transition metal oxides are promising anode candidates due to their high capacity and low cost.

Recently, the Ministry of Industry and Information Technology has publicly solicited opinions on the "Requirements for the Review of Access Licenses for Road Motor Vehicle Manufacturers (Draft for Comment)" and the "Requirements for the Review of Access Licenses for Road Motor Vehicle Products (Draft for Comments)", proposing that enterprises should build used power batteries Stable recycling channels ensure the safe recycling of used power batteries. In the process of scrap recycling of powe

Gree Group terminated the acquisition of Zhuhai Yinlong, and Gree's plan to "cross-border car manufacturing" has now come to an end. At the beginning, Gree's proposed acquisition of Yinlong was as high as 13 billion yuan. What was it that attracted Gree to pay such a high price? It is reported that Dong Mingzhu, chairman of Gree Electric, values ​​Yinlong's core competitiveness - lithium titanate battery technology. Where does Yinlong lithium titanate battery technology come from? Can it be

Recently, Japan's New Energy Industry Technology Comprehensive Development Agency recently announced that some companies and academic institutions in the country will jointly develop the next-generation electric vehicle all-solid-state lithium battery in the next five years, and strive to apply it to the new energy vehicle industry as soon as possible.(Lithium - Ion Battery Equipment) The project is expected to have a total investment of 10 billion yen (about 580 million yuan), and 23 automotive, battery and

The commercial application of proton exchange membrane fuel cells is limited by the sluggish oxygen reduction kinetics at the cathode. At present, the most effective strategy to improve the catalytic activity of oxygen reduction is to optimize the bonding energy between the catalyst and the oxygen-containing species by alloying the transition metal M (M=Fe, Co, Ni, Cu, etc.) with the noble metal Pt. Enhanced catalytic activity for oxygen reduction. Recent studies have shown that interfacial catalysts can provide

The poor consistency of lithium battery cells has plagued the design of lithium battery packs for a long time. The consistency we are talking about here not only refers to parameters such as capacity and voltage in the traditional sense, but also includes the capacity decay speed of single cells, Factors such as the decay rate of internal resistance and the temperature distribution of the battery pack. Ideally, lithium batteries from the same batch should have the same electrochemical performance, but in practice t

Xinhua News Agency, Washington, March 1. Chinese scientists have developed a lithium battery that can be used at minus 70 degrees Celsius. It is expected to be used in extremely cold regions of the earth and even in outer space in the future. Research published in the latest issue of the American energy academic journal "Joule" shows that the new battery developed by Xia Yongyao's team at Fudan University in China uses ethyl acetate, which has a low freezing point and can conduct electricity at ext

This year's "two sessions", Li Xiangbin, an "old acquaintance" of Hefei Public Transport, who was re-elected as the representative, focused on the field of new energy public transport. As an important position for new energy vehicles in the country, Hefei Bus has always been a signboard. "But there are still shortcomings in battery life, and the country should speed up research and development." Hefei New Energy Electric Bus started early. As early as January 23, 2010, Hefei Bus
