Study on the Novel Nanometer Additive for Secondary Batteries

This paper presents the effect of the nanometer additive on the performance of the electrodes in secondary nickel metal hydride battery. The influence of the nanometer additive on discharge storage capacity of the electrode is studied and the electrochemical property of hydride electrode is investigated. Galvanostatic tests indicate that the nanometer additive incorporated electrode exhibits better high rate discharge capability, superior charge acceptance ability and longer cycle life compared with the blank electrode. The nanometer additive greatly decreases the weight and volume of the secondary battery, and makes it better meet the requirement as power sources for electric and hybrid vehicles
