Lithium-ion batteries: Cutting-edge research in safety and applications

In recent years, with the popularity of electronic products, the demand for lithium-ion batteries with high safety is increasing, which has attracted great attention from the industry. Lithium-ion battery safety and its cutting-edge application research has always been a hot field of science and technology development. This paper will focus on the safety of lithium-ion batteries and its application prospects for systematic research. It aims to provide reference for the research and development of lithium-ion batteries and promote related scientific and technological innovation.

How many types of lithium batteries are there?

We often talk about ternary lithium batteries or iron lithium batteries, which are named after positive electrode active materials. The six common types of lithium batteries include: lithium cobalt oxide, lithium manganese oxide, nickel cobalt manganese oxide (NCM), nickel cobalt aluminum oxide (NCA), lithium iron phosphate, and lithium titanate.

How much do you know about the basic performance testing of lithium-ion batteries?

Usually, after the lithium-ion battery completes the formation aging process, the battery needs to be inspected and analyzed. So what kind of testing is usually conducted? Today, let's briefly talk about battery testing. Fans of lithium battery pie can leave messages and communicate in the background. Generally speaking, regarding the lithium-ion battery or other system to be analyzed, electrochemical researchers will conduct basic testing and electrochemical performance tests to further confirm and determine the problems that may occur in the battery or system.
