"Higher, faster, stronger" is the familiar spirit of Olympic competition. This motto of the Olympic movement was proposed by Coubertin, the founder of the modern Olympic movement, and elaborates on the Olympic movement's spirit of continuous improvement and never-satisfied struggle. Switching to the electric vehicle industry, as the power lithium battery at its heart, in terms of battery material selection and technical research, developing new technologies to supply higher energy density and achie

Recently, researcher Tang Yongbing and his research team from the Functional Thin Film Materials Research Center of the Institute of Integration, Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, successfully developed a new high-performance, low-cost lithium battery technology, which is expected to break the existing lithium battery industry pattern.

Lithium batteries are widely used in new energy electric vehicles and energy storage due to their superior performance. However, the micro-short circuit problem of lithium batteries related to vehicle and energy storage battery packs is a safety hazard during use. In order to diagnose whether micro-short circuits occur in battery packs, Short circuit and determine micro-short circuit cells. This paper proposes a method to diagnose micro-short circuits based on changes in relative charging time of cells. In this met

Currently, the new energy vehicle market has higher requirements and expectations for reducing the cost of power lithium battery systems and improving electrical performance and safety and reliability. Power lithium battery and vehicle companies must accelerate technological innovation to create more possibilities. Due to its excellent safety performance, energy density, cycle life, operating temperature range and other aspects, solid-state lithium batteries are considered to be the next-generation battery products

Compared with traditional liquid lithium batteries, solid-state lithium batteries (SSLB) use solid electrolytes instead of organic electrolytes. Their safety and energy density are greatly improved, which can effectively reduce safety hazards of electric vehicles and relieve users' range anxiety. Solid electrolyte, as an electronic insulator and ionic conductor, is one of the core elements of SSLB. At the same time, it has problems such as low ionic conductivity, large interface impedance, and poor interface st

[Phenomena] From mobile phones, computers, wearable devices, to new energy vehicles and electric bicycles, lithium batteries are widely used. While market demand is increasingly strong, lithium batteries themselves also have shortcomings such as high production costs and low reserves of key raw materials, which has forced some companies to accelerate the search for alternative technologies and turn their attention to new batteries such as magnesium, zinc, and sodium. Some media pointed out that the global race arou

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.
