Abstract

The invention is suitable for the field of soft package lithium batteries, and provides a soft package lithium battery cell module assembly structure and an assembly method. The structure comprises a cell, a control panel, a power source connecting wire, an insulating plate, a connecting part, a damping part and a heat dissipation part; the control panel is connected to the top of the cell through a wire. The invention solves the problems that a layer-by-layer packaging structure is generally adopted when an existing soft package lithium battery is assembled, the surface is connected and protected only by using a nylon adhesive tape or coating insulating silica gel, the firmness degree after packaging is low, the battery is liable to fall apart when in use, the heat dissipation effect of the packaged soft package lithium battery is achieved by blowing a shell of the soft package lithium battery through natural wind, the passive heat dissipation mode is low in efficiency, internal temperature cannot be dissipated in time after the soft package lithium battery is used for a long time, the abrasion of the soft package lithium battery is easily aggravated, the soft package lithium battery is swelled, the soft package lithium battery is inconvenient to use by a user, and the use risk of the soft package battery is increased.

Description

technical field [0001] The invention belongs to soft-pack lithium batteries, in particular to a soft-pack lithium battery cell module assembly structure and an assembly method. Background technique [0002] In a lithium battery, the smallest unit is the battery cell. A group of battery cells can form a module, and several modules can form a battery pack. The soft pack lithium battery is a kind of battery pack. The existing soft pack Lithium batteries are generally assembled in a layer-by-layer packaging structure. Only nylon tape or insulating silica gel is used for connection and protection on the surface. Relying on the natural wind to blow its own shell to dissipate heat, this passive cooling method is inefficient, and the internal temperature cannot be dissipated in time after long-term use, which will easily aggravate the wear of the pouch battery and cause the pouch battery to bulge, which is inconvenient The use of the user increases the danger of using the pouch bat...
