目前在国际二次电池市场中,锂电池、镍氢（Ni-MH）电池与镍镉（Ni-Cd）电池已成鼎足之势。 据推测,Ni-Cd电池占有的市场营销额将从1998年的14.4亿美元逐渐下跌到2002年的13亿美元。Ni-Cd电池的装运量将从18.6亿只增长到20亿只。Ni-MH电池的能密度虽然与锂离子电池相近,但质量上要重得多。预计Ni-MH的市场将由大约8.26亿美元上升到2003年的14亿美元。 2000年全世界的电池市场规模为370亿美元,锂电池占29亿美元,这29亿美元中,锂原电池为11亿美元,二次锂电池为18亿美元。锂原电池主要用于照相机市场和某些其它电子应用。而锂离子二次电池占有的主要应用市场是新型蜂窝电话（手机）
Currently in the international secondary battery market, lithium batteries, nickel-metal hydride (Ni-MH) batteries and nickel-cadmium (Ni-Cd) batteries have become a full-fledged trend. It is assumed that the amount of marketing for Ni-Cd batteries will gradually fall from 1.44 billion U.S. dollars in 1998 to 1.3 billion U.S. dollars in 2002. The shipment of Ni-Cd batteries will increase from 1.86 billion to 2 billion. Although the energy density of a Ni-MH battery is similar to that of a lithium ion battery, it is much heavier in quality. The Ni-MH market is expected to rise from approximately 826 million U.S. dollars to 1.4 billion U.S. dollars in 2003. In 2000, the battery market in the world was 37 billion U.S. dollars, and lithium batteries accounted for 2.9 billion U.S. dollars. Of the 2.9 billion U.S. dollars, the lithium primary battery was 1.1 billion U.S. dollars and the secondary lithium battery was 1.8 billion U.S. dollars. Lithium primary batteries are mainly used in the camera market and some other electronic applications. The main application market for lithium ion secondary batteries is a new type of cell phone (mobile phone)
