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

During charge and discharge, the cell’s thickness change leads to pressure variation and directly influences the performance of electrochemical properties, safety, and reliability of cell, module, and battery. In order to study the change and correlation clearly, the modeling and simulation for the actual work structure and status of batteries (in-situ thickness, in-situ pressure characteristic
