摘　　要：为提高LiFePO_4电化学性能,综述了现有的碳表面包覆工艺,主要有高温固相合成法,低温液相合成法,液相共沉法,水热合成法及微波合成法.指出LiFePO_4今后应在合成方法、掺杂机理、混合掺杂以及掺杂物质量的配比上加以研究,从而提高其电化学性能.In order to improve LiFePO4 electric chemical property, the methods of wraping up and cover craft of carbon were reviewed. Mainly have high temperature solid phase synthesis, low temperature liquidphase synthesis, liquid phase settling method, hydro-thermal synthesis, microwave synthesis. It points out LiFePO4 should be studied on synthesis method, doping mechanism, mixture and mixture ratio, thus improve LiFePO4 electric chemical property.
