电动汽车电池技术发展综述

摘要

With the growing emphasis on saving energy and protecting environment, electric cars become the focus that the govern-ment and the vehicle companies pay attention to. Battery technology is a key technology that should be solved in the development of electric vehicles. This paper compares the working principle and characteristics of several major power batteryies, introduces gra-phene batteries and air batteries developed in nearly two years and looks forward to the future development prospects of various bat-teries.%随着节能环保日益受到重视，电动汽车已经成为政府和汽车企业关注的热点，其中电池技术是电动汽车发展中需要解决的关键技术之一。比较了几种主要动力电池的工作原理和特性，介绍了近两年新出现的石墨烯电池和空气电池，并展望了各种电池未来的发展。
