Abstract: Lithium-ion secondary batteries, boasting such merits as high capacity, long cycle life, environmental-friendliness and high safety, have been widely applied to such portable electronic devices as mobile phones and notebook computers. Along with the technological development, lithium-ion secondary batteries are also seeing great application prospect with electric vehicles (EV) and energy storage, which is to exert a profound influence on people's life in the future. The recent years have witnessed continuous improvement on the capacity and cycling performance of lithium-ion batteries, and the market is to see the launching of lighter, thinner and smaller lithium-ion batteries with higher capacity and lower cost. The authors deal with the historical and latest development of lithium-ion battery as well as the current applications.
