【Pacific Science and Technology News】 Recently, announced an important sulfide solid battery patent- Materials and preparation methods, lithium -ion batteries ".The patent application on May 5, 2023 marks a major breakthrough in Huawei in the field of solid battery technology.
According to the patented content, Huawei successfully developed a new solid-state electrolyte by doping specific elements in sulfide materials.This doped sulfide material is applied to lithium ion batteries, which can significantly improve the service life of the battery, while. At the same time, it has the advantages of high energy density, high safety, long cycle life and high stability.
This technical achievement of Huawei effectively solves the problem of capacity attenuation caused by the multi -sulfide (LISX) shuttle in liquid lithium lithium sulfur battery system, which clearly obstacles the improvement of battery performance.And this technology is not only suitable for electric vehicles (EV), but also provides high -performance battery solutions for various application scenarios such as energy storage, which is expected to promote the rapid development of related industries.
Huaweis partners in the field of solid battery include Penghui Energy, Ruifeng High Materials, Nandu Power, Fengyuan Co., Ltd., Wei Lan New Energy, Here, pilot intelligent and other companies to jointly promote the research and development and application of solid -state battery technology.
The solid battery industry is ushered in a period of rapid development.Both Beijing Yizhuang and Jiangxi have put into production the mass production lines of all solid -state lithium batteries, respectively. In the Ningde Times, Qingtao Energy, etc., companies have made significant progress in the field of solid battery.It is expected that in the next few years, solid -state batteries will realize small batch production and move towards widespread development.
