Abstract

The invention relates to the technical field of battery infiltration equipment and particularly relates to a device for assisting battery infiltration. The device comprises a rotating unit, a heatingunit and a shell with a cavity, wherein the rotating unit is rotatably mounted on the shell and is provided with an extending part extending into the cavity, the extending part is arranged to be capable of installing and driving a plurality of batteries filled with the electrolyte to rotate, and the heating unit is arranged on the shell and is arranged to be capable of heating the chamber so as toenable the batteries accommodated in the chamber to reach the infiltration temperature. The device is advantaged in that the rotating unit and the heating unit are arranged, so the battery injected with the electrolyte can be infiltrated in a rotating mode at the infiltration temperature, the infiltration time is remarkably shortened, secondary electrolyte injection is not needed, and infiltration efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of battery soaking equipment, in particular to an auxiliary battery soaking device. Background technique [0002] At present, lithium-ion batteries need to use liquid injection to introduce electrolyte. Specifically, in the process of introducing the electrolyte, the lithium-ion battery needs to be injected first, and then the battery filled with the electrolyte is placed at a high temperature and kept warm for a period of time to perform the infiltration operation, so that the electrolyte can infiltrate the interior. pole group. However, when the electrolyte of the battery is infiltrated, it is difficult for the electrolyte to penetrate into the electrode group completely and quickly at first, and part of the electrolyte will be concentrated in the gaps inside the battery, making it difficult to penetrate into the electrode group, resulting in the need for electrolyte It takes a long standing time to full...
