"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. Relevant research results "ANovelandGeneralizedLithium-IonBatteryConfigurationUtilizingAlFoilasBothAnodeandCurrentCollectorforEnhancedEnerg

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

Global lithium resources are widely distributed, but reserves are limited. At present, they are mainly concentrated in South America, my country, and some places in Africa. my country's lithium resources are concentrated in salt lakes and ores. About 70% of the currently proven reserves are concentrated in the salt lakes of Qinghai, and some are scattered in mines. Due to their different natural endowments, these two resources have differences in later mining, extraction, production technology and product quali
