Abstract

The invention discloses a lithium ion battery, which comprises a shell, an electric core and an electrolyte; wherein, the shell has a cavity for the electric core, and the electric core and the electrolyte are sealed and packaged in the cavity for the electric core; the shell is provided with a liquid injection Structure, the liquid injection structure communicates with the cavity of the battery cell, and is used to replenish electrolyte into the cavity of the battery cell. Through the above method, the present invention provides a liquid injection structure on the lithium-ion battery casing, which can replenish liquid during the battery cycle, and can greatly improve the service life of the battery without increasing the volume.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a lithium ion battery. Background technique [0002] Lithium-ion batteries have been widely used in digital, handheld devices, wearable and power fields due to their high energy density, high output platform, and no memory characteristics. With the improvement of people's awareness of environmental protection, lithium-ion batteries will still occupy a large share in the future energy industry. According to the GB18287 national standard, if the battery discharge time at 0.2C is less than 3h during use, the battery life is considered to be terminated. At present, there are a large number of lithium ions that have reached the scrapping standard in the Chinese market. How to improve the service life of lithium-ion batteries and reduce the annual production of waste batteries is of great significance to individual consumers and the national energy industry.
