This paper deals with the structure design and electrochemical studies of bipolar Ni/MH batteries for hybrid vehicles. An improvement is applied in bipolar battery design, and such bipolar Ni/MH batteries with 5 sub-cells have been assembled and investigated. Testing results show that bipolar batteries with improved structure have better compression tolerance and cycle performance than conventional ones. In addition, the improved bipolar batteries display excellent large current discharge ability and high power density. As simulating working conditions for hybrid vehicles, the batteries show good stability during pulse cycles, which verifies the possibility of being used as a power storage device on hybrid vehicles.展开更多

Through the SCP perspective in the modem industrial economics, we can not only reveal the roles of the public organizational structures in the organizational performances, but also help to reflect the problems existing in the organizational structures from the performances, and improve the market performances by optimizing the organization structures. This paper tries to put forward the relationship between them, and makes an analysis of the future development trend.展开更多
