Factors on Storage Performance of MH-Ni Battery

摘要

The open voltage of batteries shows different status after MH-Ni batteries are stored for a period of time.Some batteries with 0, 0.9 ～ 1.1V and above 1.1 V were chosen to study their corresponding internal resistances, open voltages and the reduction of capacities, etc.On the basis of battery reaction principle, battery samples were analyzed,and factors causing different storage performance were found out.Therefore, some references on the improvement of battery storage performance were provided.
