Abstract
A method for manufacturing a circular electrode apparatus of a battery for resistance stability improvement comprises the following procedures. First, an electrode structure of a battery including an upper electrode plate, an over-current protection device and lower electrode plate is provided, wherein the over-current protection device is a lamination constituted of an upper metal foil, a current-sensitive layer and a lower metal foil. Secondly, the electrode structure is treated by high-speed impact, vibration, hot-cold impact, acid pickling, water pickling or sand blasting to become the electrode apparatus of the present invention whereby the mean value of the resistance of the electrode apparatuses is below 0.05 ohm, and the deviation of the resistances of the electrode apparatuses is below 0.005 ohm at 25° C.
