Power battery is the core component of new energy vehicles, and the role of battery diaphragm in the power battery is very important, mainly in a narrow space to separate the battery positive and negative level plate, to prevent the contact between the poles caused by short circuit, but can ensure the ions in the electrolyte in the positive and negative pole through freely Therefore, the diaphragm is the core material to ensure the safe and stable operation of lithium ion battery.

The lithium battery charging cycle is closely related to the lithium battery life A charging cycle specifically refers to a lithium battery full charge and discharge process.

Water - power bottle is a lead - acid battery Because of the high liquid content in the battery, it is often called a "water and electricity bottle".

In order to break through the "squeeze" of square battery and the technology accumulation and usage habit of cylindrical battery for more than 50 years, soft-pack battery needs to give full play to its advantages of safety and high densitySoft-pack batteries have a bright futureAccording to statistics from qidian research institute (SPIR), in terms of the output of batteries of different shapes, the shipments of square cells in 2017 were the largest, but in terms of their year-on-year growth rate, the cylinder and soft package grew the fastest, reaching 57% and 26% respectively.

Using the wrong battery under the wrong conditions can cause problems and explosions Careful design can avoid accidents such as battery rupture and explosion, and reduce the risk of harmful electrochemical reactions and mistakes.

1 Short circuit will lead to explosion.

Editor's note: the electric vehicle industry is still at a confused stage, the responsibilities in various fields are not yet clear, and the industrial chain has not been initially formed When the first batch of electric vehicles are about to be scrapped, the situation is not optimistic.

We often talk about ternary lithium batteries or iron lithium batteries, which are all named after the positive active material This article summarizes six common lithium battery types and their main performance parameters.

Except the six fuel cells of PEMFC, AFC, PAFC, MCFC, SOFC and DMFC, there are microbial fuel cells and regenerative fuel cells Microbial fuel cells are essentially systems that harvest electrons produced during microbial metabolism and direct electrons to produce electricity.

Lithium-ion battery charging safety of mobile phones is increasingly valued by consumers Therefore, charger manufacturers must master the specifications and characteristics of lithium-ion batteries when designing products, and use rechargeable chips with perfect battery detection and protection functions to reduce danger due to conditions such as over current, over voltage or over temperature.
