简要介绍了我国电动车的开发现状，指出了发展电动车的瓶颈是电池；阐明了锂离子电池对发展电动车的作用，特别强调目前的关键是研发适于电动车的锂离子电池材料；简述了作者的实验室在电动车锂离子电池关键材料研究方面的最新进展。

After a brief introduction to the present situation of electric vehicle (EV) in China, it has been pointed out that the neck for developing EV is battery. The most important role played by Li-ion batteries in the development of EV has been evaluated. It has been pointed out that the key fact at the moment is to develop materials which can meet the requirements of Li-ion battery for EV. Some progresses obtained in the author’s laboratory in this field have been reviewed.
