Problems solved by technology

In the automatic production process of soft-packed lithium batteries, it is necessary to fold the edge of the lithium battery, and use automatic folding to form. The folded aluminum-plastic film encounters external forces such as extrusion during the trial process, which may cause damage to the edge-sealing section. If the circuit is turned on, leakage current is prone to occur, which will further cause problems such as corrosion and swelling
[0004] The existing technology usually uses moisture-curing hot-melt glue to bond the edge-wrapped section of the lithium-ion battery, and the bonding strength can meet the requirements of use, but the moisture-curing hot-melt adhesive has poor storage stability of the glue, and the final curing time is too long, etc. shortcoming
