BATTERY SUBJECTED TO NICKEL BRIGHT ELECTROPLATING

摘要

[PROBLEMS] To provide a battery capable of ensuring stably over a long term a good contact state that allows an efficient take-out of a high current from a low voltage high capacity battery without increasing the cost, forcing an extra burden on the apparatus side or damaging the appearance as a commodity significantly. [MEANS FOR SOLVING PROBLEMS] In a battery having electrode terminal parts (12a, 32a) made by applying nickel bright electroplating to a steel plate, finish section on the surface of the steel plate is subjected to dull finish and the ratio of sulfur and sulfur compound in the nickel bright electroplating is set at 0.02 wt% or below.
