Coiling-type laminated battery manufacturing method coating adhesive on membrane to fix pole pieces

2015 
The invention provides a coiling-type laminated battery manufacturing method coating an adhesive on a membrane to fix pole pieces. The coiling-type laminated battery manufacturing method comprises positive and negative pole piece manufacturing processes. Positive and negative pole pieces adopt the following steps of: after respectively carrying out coating, baking and rolling on positive and negative current collectors and regularly slitting and cutting the positive and negative current collectors according to a design size, coating an adhesive layer on the membrane to fix the positive and negative pole pieces at an interval on the membrane; then coiling the membrane on which the pole pieces are fixed to form a laminated battery, wherein the membrane takes an effect of isolating the positive and negative pole pieces to prevent a short circuit. According to the coiling-type laminated battery manufacturing method, the laminated battery manufactured by coiling the membrane on which the pole pieces are fixed can be used for manufacturing a special-shaped battery, cathode lithium precipitation caused by malposition of a cathode and an anode can be prevented, the problem of cell distortion caused by a tension change of the membrane after battery cycle can be solved from the source, stability and safety of the battery can be effectively improved, labor cost is reduced, and production efficiency is improved.
