Knowledge And Technology

Kirin battery, the third-generation CTP technology, has reached a new high in system integration in the world, with a volume utilization rate exceeding 72%, and an energy density of up to 255Wh/kg, which can easily achieve a 1,000-kilometer battery life. Kirin batteries are essentially lithium-ion batteries, mainly structural innovations, both lithium iron phosphate, and ternary

The development of portable electronic devices, electric vehicles, and renewable energy systems urgently requires the support of high-performance and high-safety electrochemical energy storage devices, but the current commercial lithium-ion batteries based on traditional organic electrolytes are approaching the performance bottleneck and are toxic. , Volatile and flammable ester electrolytes have great potential safety hazards. Solid-state

1.Why are lithium-ion batteries so powerful? The performance and reliability of lithium-ion batteries depend to a large extent on the electrolyte. The most commonly used electrolytes today are composed of cyclic and linear carbonates containing soluble lithium salts, typically lithium hexafluorophosphate, which have low viscosity and good ionic conductivity. However, the electrolyte is unstable at

The latest achievements of lithium battery technology are as follows. 1. Ultra-low concentration electrolyte realizes highly stable lithium metal battery! The interfacial structure of electrodes is closely related to the electrochemical performance of lithium metal batteries (LMBs). In particular, a high-quality solid-electrode interface (SEI) and a uniform and dense Li deposition/stripping process are crucial to

“Lithium battery” is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Lithium batteries can be roughly divided into

Battery development: performance such as ultra-fast charging and safety is the main direction; focus on structural innovations such as large cylinders and long batteries 1.Battery performance trends Battery factories lay out technical directions such as high energy ratio, ultra-fast charging, and safety. The core battery factories of CATL and BYD are all laying out in

A new additive in electrolyte formulation could reduce the risk of thermal events in lithium-ion batteries. Currently, many companies in the industry are steadily investing in the research and development of solid-state batteries due to their increasing density and safety. For now, however, we still need ways to ensure the safety of existing technologies.In late

Lithium batteries have quickly occupied the solar energy market due to their safety, lightweight, long service life, complete charge and discharge, low maintenance costs, and no memory effect. Compared with traditional lead-acid batteries, lithium batteries have the characteristics of no pollution, long service life, no memory effect, many times of charge and discharge, and long
