Inventor: CHOE SEOK MO
IPC: H01M10/06
Filed: 2020-09-28
Abstract: The present invention relates to a method for strengthening a fusion strength of a lead-acid battery case and cover and, more specifically, to a method for strengthening a fusion strength of a lead-acid battery case and cover, in which heat is applied to a fusion surface between a cover (10) and plastic battery case (20) of a lead-acid battery by a sawtooth heating plate to melt the fusion surface in a sawtooth shape so that a fusion area is increased to increase airtightness of a side fusion area during thermal fusion between the cover (10) and the plastic battery case (20) of the lead-acid battery, thereby increasing fusion strength (weld strength). Accordingly, since airtightness is easily removed due to distortion by bending or shrinkage of a cover of a lead-acid battery case when fusion is performed in the lead-acid battery, a sawtooth-shaped fusion part is provided to sufficiently widen a fusion area, thereby preventing leakage of lead-acid batteries.
