Description

technical field [0001] The invention belongs to the technical field of power batteries, and in particular relates to a soft pack lithium battery pack and an assembly method thereof. Background technique [0002] The soft-pack lithium battery is a battery covered with a polymer shell on the liquid lithium-ion battery. The structure is packaged with aluminum-plastic film. In the event of a safety hazard, the soft-pack battery will only burst when there is a safety hazard. Therefore, the overall safety High performance, but with the continuous development of the economy, people have put forward higher requirements for the soft-pack lithium battery pack. The existing lithium battery pack is complicated to install and the process is cumbersome, and needs to be improved. [0003] A patent for a soft-packed lithium battery pack, application number (CN201620276184.9), discloses a soft-packed lithium battery pack, including at least two single lithium batteries, the lithium battery p...
