LITHIUM ION BATTERY AND METHOD OF MANUFACTURE THEREOF

摘要

A high-performance lithium ion secondary battery which can be made small in size and light in weight, can be formed into any shape without using a strong outer packaging can, and has a strong structure and a high safety, and a method for manufacturing the battery easily with high productivity. The method for manufacturing the lithium ion secondary battery includes a process wherein a positive pole (3) made by putting a positive pole active material layer (32) and a positive pole current collector (31) together and a negative pole (5) made by putting a negative pole active material layer (52) and a negative pole current collector (51) together are stacked with adhesive resin (6) including plastic resin placed in parts of a space between the positive pole (3) and the negative pole (5), and a process wherein the adhesive resin (6) is plastically deformed. By this method, the lithium ion battery can be manufactured easily and the productivity can be increased.
