According to the report of the automobile news website Electrek, Toyota Motor Corporation announced last week that it has made a major technological breakthrough in the research and development of lithium-ion battery technology. Not only has the service life of the lithium-ion battery been extended, but the range of electric vehicles can also be increased by 15%. According to reports, Toyota said that the breakthrough in lithium-ion battery technology will increase the range of electric vehicles by at least 15%.

Recently, the Watt Laboratory of Huawei Central Research Institute announced at the 57th Japanese Battery Conference that it had achieved a major research breakthrough in the field of lithium-ion batteries and launched the first high-temperature and long-life graphene based lithium-ion battery in the industry. The experimental results show that the new high-temperature technology based on graphene can increase the upper limit service temperature of lithium ion batteries by 10 ℃, and the service life is twice that o

Recently, foreign media reported that Honda will bring many "black technologies" to the CES Electronics Show in 2019, including the latest wireless charging technology and a series of intelligent security solutions based on V2X communication technology. Honda's wireless charging technology is a two-way energy management system based on the V2G Internet of Vehicles. Compared with the traditional wireless charging technology, it adds the function of returning power to the power grid to achieve the pu

Scientists from Russia, France, Sweden and Greece have jointly developed an industrial technology to purify graphene. The new method makes graphene more stable, and even if exposed to ozone for 10 minutes, it is "harmless". The researchers said that this achievement is an important progress in the field of nano electronics technology and will greatly promote the development of this field. According to the Russian satellite network, scientists from Russia, France, Sweden and Greece have jointly develope

Electric vehicles, powered by electricity instead of fossil fuels, are the only long-term solution for future transportation. As the heart of electric vehicles, the power battery system can be successfully promoted only if it is fully understood. From the perspective of the development trend of the main on-board power battery of electric vehicles at home and abroad, this paper focuses on the analysis of the promising lithium-ion battery and its battery management system. The unbalanced charging of lithium ion ba

The lithium-ion battery is mainly composed of positive pole, negative pole, diaphragm, electrolyte, and structural parts. On the outside of the lithium-ion battery, the electrons of the negative pole are transmitted to the positive pole through wires and loads, while inside the battery, the positive and negative poles are connected through electrolyte. When discharging, Li+diffuses from the negative pole to the positive pole through electrolyte, and is embedded in the crystal structure of the positive pole. Therefo

On January 23, the key technology and engineering demonstration project of low-cost and high-efficiency hydrogen fuel cell, a major scientific and technological project in Shanxi Province, was launched. The project will rely on the abundant hydrogen energy resources in Shanxi Province to carry out the research and development of key technologies of low-cost and high-efficient hydrogen fuel proton exchange membrane fuel cell (PEMFC) power system, and achieve the demonstration goal of hydrogen fuel cell system ind

In the "three horizontal and three vertical" layout of China's new energy vehicles, the fuel powered lithium battery occupies an important position. In order to promote the development of fuel powered lithium battery vehicles, China has given special care, and the pure electric vehicle subsidy has introduced a retrogressive mechanism. However, the fuel powered lithium battery subsidy has not been affected and is still implemented in accordance with the original standards. With the support of polici
