If new energy vehicles want to be truly close to the experience of traditional gasoline vehicles, shortening charging time, improving cruising range and charging convenience are unavoidable topics. Dr. Wang Shengwei, head of the fast charging project of CATL New Energy Technology Co., Ltd. (CATL), said that the "superconducting electronic network" and "fast ion ring" technologies developed by CATL are a perfect combination, and the lithium iron phosphate fast charging core has been developed int

The energy-saving and new energy vehicle technology roadmap announcement conference was held in Shanghai on the 26th. The roadmap was commissioned by the National Strategic Advisory Committee for Building a Manufacturing Power and the Ministry of Industry and Information Technology, and was researched and compiled by more than 500 industry experts organized by the my country Society of Automotive Engineering over a year. According to reports, this technology roadmap plans the development of my country's auto

When it comes to driving, safety comes first. As the most eye-catching newcomer, electric vehicles urgently need to improve themselves in the field of safety. The development of battery pack mechanics simulation models plays a key role in the development of collision safety of future electric vehicles. Research on the mechanical behavior of the component materials of lithium batteries aims to establish a basis for refined battery pack models. This article will introduce to you the relevant research of this research

In a narrow sense, ternary materials refer to stoichiometric nickel-cobalt-manganese three-component layered cathode materials. This type of material was first developed by Chinese scholar Liu Zhaolin in 1999 at the Institute of Materials Research and Engineering (IMRE) affiliated to A-Star in Singapore. ) was reported when I was working on it. Since then, many international research groups have conducted very detailed and in-depth research on this series of materials. In a broad sense, the scope of ternary mate

Recently, Zhang Yuegang's research group at the Suzhou Institute of Nanotechnology and Nanobionics, Chinese Academy of Sciences independently developed and designed an in-situ scanning/transmission electron microscope electrochemical chip, which enabled real-time observation of the charging process of lithium sulfide (Li2S) electrodes; in fully understanding Li2S charging Based on the discharge mechanism, a high-nitrogen-doped graphene-loaded lithium sulfide material was designed as the battery cathode. By cont

Since March, there have been 7 or 8 electric vehicle battery fire incidents in China, bringing the issues of battery safety and battery management system safety to the forefront. In these fire incidents, the temperature of the power lithium battery was uncontrollable and rose linearly after being heated, which led to combustion and explosion. This phenomenon has a professional term called thermal runaway of power lithium batteries. The rise in battery temperature is the culprit of fire and combustion, and the re

The improvement of battery life determines the fate of electric vehicles. Scientific researchers are pursuing new discoveries in chemistry and materials, and car companies and battery suppliers are working together to reduce costs and add energy. Among the emerging new technologies, a lot of research has been invested in replacing lithium-ion chemistries, and some have become popular applications and solutions. 1. MIT: Semi-solid lithium flow battery Researchers at the Massachusetts Institute of Technology in

my country is one of the most important producers of lithium batteries. In the face of the rapid development of the lithium battery industry, in order to strengthen management and promote industrial transformation and upgrading, the Ministry of Industry and Information Technology recently announced the "Lithium Battery Industry Standard Conditions" and the "Lithium Battery Industry Standard Notice Management Interim Measures." The market size of lithium battery industry has reached 82 billion
