INTEGRATED BODY OF BATTERY ELECTRODES

摘要

PURPOSE:To reduce space between positive and negative electrodes and improve discharge property by providing a spiral spring inside the negative or the positive electrode can and fixing a current collector thereon. CONSTITUTION:A current collector is spot welded on the inside of the negative electrode can 1 and the negative electrode made of lithium is stuck thereon under pressure. Polypropylene unwoven cloth is put on it and provided with the positive electrode substantially made of manganese dioxide into which electrolyte is immersed. A positive electrode can 5 spot welded with the positive electrode current collector is covered thereon, and sealed under pressure to prepare a battery. At that time, a spiral conductive spring 10 is provided inside the negative electrode can 1 (or the positive electrode can 5) and it is fixed on the current collector. Thus, the negative electrode, the separator and the positive electrode can be well contacted.
