MANUFACTURE OF FLAT TYPE BATTERY

摘要

PURPOSE:To improve productivity of a high quality flat type battery having good discharge performance and shelf life by press-bonding a separator to a negative electrode accommodated in a container, and pouring nonaqueous electrolyte in a space formed between the separator and a positive electrode. CONSTITUTION:A lithium sheet 2 is press-bonded to a negative container 1 with sealant. A separator 3 is press-bonded on the surface of a lithium sheet 2. A positive electrode 4 is formed in a positive container 5. The containers 1 and 5 are faced together, and all sides of periphery of the positive container 5 are sealed except one side to form a bag-shaped container having one opening. Nonaqueous electrolyte is poured from the opening into a space formed between the separator 3 and positive electrode 4. Then the opening is sealed. By this process, a flat type nonaqueous electrolyte battery having high storage reliability is provided.
