浅析动力电池的技术发展
摘要
With an eye to the future commercialization of all-electric vehicles, the realizable targets for the near-term, middle-term and long-term developments of power batteries are proposed on the analysis of the state-of-the-art technologies for electrochemical batteries. In view of the battery systems possibly satisfying the performance targets on different stages, a technology roadmap is put forward with an emphasis on the individual and combined contributions of cathode and anode materials to the specific energies of the power batteries including Li-ion and Li-S batteries. Also, possible strategies are discussed for development of advanced materials and technologies for the power batteries. Finally, the safety issue on lithium-ion power batteries is analyzed together with a brief instruction of the safety-enhancing technologies.
