After more than 10 years of efforts, the production and sales of electric vehicles in China exceeded 500000 in 2016, and the sales of electric vehicles in 2017 will exceed 700000-800000, which has a huge impact on the automobile industry. Made in China 2025 announced that it clearly supports the development of hydrogen powered vehicles. In October 2016, the Chinese Society of Automotive Engineering announced the technical roadmap for fuel powered lithium battery vehicles, including hydrogen powered vehicles. After

On January 6, the sixth Science and Technology Innovation Conference of Guoxuan Hi Tech Co., Ltd. was held in Hefei, Anhui Province. Li Zhen, chairman of Guoxuan Hi Tech, said in his speech at the conference that China's battery technology has made significant progress in recent years, and the energy density of lithium iron phosphate has increased from 100Wh/kg in 2007 to 145Wh/kg at present. Li Zhen shared three feelings at the meeting: First, some understanding of the policy. First, the issue of "more

According to foreign media reports, the scientific team of Central University of Florida (UCF) has developed a "super battery" that can store more energy. The performance of traditional lithium-ion batteries begins to decline to varying degrees after 1500 times of charging, while the performance of this supercapacitor will not decline after 30000 times of continuous use. "Just use this super capacitor to replace the battery in your mobile phone, and then charge your mobile phone for a few secon

The Watt Laboratory of Huawei Central Research Institute announced that it had achieved a major research breakthrough in the field of lithium ion batteries: it launched the first high-temperature 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 of ordinary lithium ion batteries. As early as tw

China's new energy vehicle industry has achieved rapid development under the promotion of various overlapping policies of the government. According to the data of China Automobile Association, in 2016, the sales volume of new energy vehicles in China reached 507000, with gratifying results. However, there are still many problems hidden behind the achievements: the core technology has not been broken through, the company pays more attention to scale than innovation, and relies on subsidies. On January 14, the Ch

Recently, Toyota announced that it will develop a new generation of electric vehicle batteries in the next few years, which is expected to increase the existing range and battery life by 15%. The battery life of new electric vehicles developed by Toyota has increased by 15% Hisao Yamashige, a Toyota battery technology researcher, said: "For electric vehicles, lithium-ion battery is a key technology. It is obviously necessary to improve this technology in the future to further improve its performance.&quo

From the perspective of actual use value, lithium titanate battery is expected to bring customers lower use cost advantages by virtue of its ultra long cycle life. With the increasingly reasonable price, lithium titanate is about to perform a counter attack. Although Japan, South Korea, the United States and Germany have studied lithium titanate materials for many years, there are only two companies in the world that really have the core technology of lithium titanate materials, achieve industrial application, a

According to foreign media, researchers from the Korean Academy of Science and Technology (Korean Academy of Sciences for short) published a research paper in the academic journal Energy and Environmental Science of the Royal College of Chemistry. In this paper, researchers from the Korean Academy of Sciences described a new technology that can improve the chemical stability of electrode materials of solid oxide fuel power lithium battery (SOFC) by doping a small amount of metallic materials into oxides.(Lithium -

At present, the battery has always been the biggest bottleneck in the technology industry. No matter what electronic products are, if they have no power support, they will lose their significance. Therefore, all companies are committed to developing new battery technology, which is bound to bite this hard bone. Recently, Samsung announced that its Top Technology Research Institute has successfully developed a new battery material, graphene. New batteries based on graphene technology have higher capacity and faster
