二次电池发展前瞻——第56届国际电化学学会年会回顾

Perspective study of secondary batteries development——The 56th Annual Meeting of the International Society of Electrochemistry

介绍了2005年9月25～30日在韩国釜山召开的国际电化学学会第56届年会中有关二次电池的学术发展情况.着重指出了锂离子电池正、负极材料及电解质材料的研究发展趋势.改性尖晶石锰酸锂、锂镍锰钴氧三元复合氧化物、磷酸铁锂是目前正极材料的研究重点;锡、硅、锰等合金或与石墨的复合材料是未来很有前景的负极材料;凝胶聚合物电解质和聚合物固体电解质依然是锂离子电池电解质的研究重点.

The development of secondary batteries in The 56th Annual Meeting of the International Society of Electrochemistry （Busan, Korea, September 25～30, 2005） was reviewed. The research developing trends of Li-ion battery cathode, anode materials and electrolytes were emphasized. The focal point of the development of cathode materials was modified spinel lithium manganese oxides, lithium manganese cobalt nickel composite oxides and lithium iron phosphate, the anode materials were composite materials between carbon materials and tin, silicon and manganese alloys, electrolytes were gel and all-solid polymer electrolytes.
