Abstract

A method for manufacturing a wound type battery includes following steps: sampling the wound cores of current batch which are composed of separators (2) and electrode plates (1, 3); placing the wound cores sampled into steel cans (4), adding a curing agent (5) into the steel cans (4) so as to make the wound cores solidification, cutting the solidified wound cores along the axial direction, measuring the overlay margin Δ between the separators (2) and the electrode plates (1, 3); and revising the widths of the separators (2) and the electrode plates (1, 3) of batteries of next batch according to the overlay margin Δ measured. The method of the invention may measure and quantitatively analyze the overlay margin Δ between the separators (2) and the electrode plates (1, 3), therefore ensure the eligible rate of finished batteries.
