Abstract

The invention relates to a method for preparing lithium battery, which comprises: a, based on needed shape and size, producing aluminum composite film frame; b, based on the shape and size of frame, producing lithium-manganese dioxide battery core; c, connecting the positive and passive plates of lithium battery to the positive and passive terminals; d, putting the battery corn into the frame, and protruding the pole ear outside the frame; e, thermally sealing two edges of battery frame; f, pouring into electrolyte; g, completely thermally sealing, to form integrated plastic lithium battery. Since the invention uses aluminum composite film as the frame of lithium battery, it can produce the lithium batteries in different shapes, with high capacity, long service life and high volume utilization.
