[0002] In the production environment of lithium batteries, due to their high energy density characteristics and the occurrence of situations such as thermal expansion, the poor safety performance of lithium battery production is inevitably exposed. Therefore, there are strict requirements for the production and storage of lithium batteries, and battery restraint devices are used to restrain lithium batteries.

[0003] For example, the public notice document: CN211789159U, named "Battery Formation Restraint Device", includes a base and a partition group, where: the partition group includes a plurality of partitions arranged in parallel, the partitions are slidably arranged on the base, and the partitions can reciprocate along the arrangement direction of the plurality of partitions. The partition group includes pairs of limit blocks arranged at intervals between adjacent partitions, the limit blocks are arranged to be able to reciprocate along the arrangement direction of the plurality of partitions, and after two adjacent partitions and the pairs of limit blocks located between the two adjacent partitions move towards each other, they can jointly define a restraint chamber for restraining the battery.

[0004] The existing battery restraint devices occupy a large space when placed, are not convenient for users to disassemble and assemble, and cannot adjust the corresponding volume size according to the number of batteries for restraint operations; therefore, they do not meet the existing requirements, and for this reason, we propose a restraint device for square batteries.
