Abstract

The invention discloses a battery interface improvement method and a battery interface improvement system. The method comprises: injecting a first preset ratio of electrolyte solution into the battery body to obtain a primary liquid-injected battery; performing static treatment on the primary liquid-injected battery, During the standing process, the liquid-injected battery is controlled to rotate at a preset angle every preset interval; after the standing time reaches the preset total standing time, the primary liquid-injected battery is pre-charged with negative pressure to obtain a semi-finished battery . The present invention changes the standing posture of the battery during the standing process, so that the electrolyte inside the battery can fully flow, reducing the phenomenon of deposition at the bottom of the electrolyte caused by gravity, which is beneficial to improving the wetting effect of the electrolyte, increasing the wetting efficiency, and shortening the static time. Set time, improve production efficiency, effectively improve the battery interface lithium analysis and black spots.

Description

technical field [0001] The invention relates to the technical field of battery preparation, in particular to a battery interface improvement method and a battery interface improvement system. Background technique [0002] Lithium battery is the fastest growing item in the new energy industry. Lithium battery is more and more used in daily life, and has been widely used in the fields of automobiles and energy storage. [0003] With the development of demand for lithium batteries in various industries, the safety performance requirements of lithium batteries are getting higher and higher, and the compaction density and external dimensions of battery pole pieces are also increasing. In the battery preparation process, the following problems will occur: ( 1) As the compaction density of the pole piece increases, the active material in the pole piece becomes denser, and the effect of the electrolyte infiltrating the pole piece becomes worse and worse; (2) As the size of the batte...
