The nickel button plate is mainly divided into a disposable negative plate and a permanent negative plate. The disposable polar plate is formed by sticking a conductive metal plate and an insulating film after hole making, has simple and convenient manufacturing method, is easy to damage, and has high cost due to short service cycle. Permanent polar plate is led electrical pillar and insulating layer to make by the backup pad more, and the part is many and the manufacturing process is comparatively loaded down with trivial details, leads electrical pillar and insulating layer in the use and easily appears the gap and lead to the dropout difficulty. Due to the defects of the traditional pole plate, the nickel button is difficult to produce in a large scale.
