摘　　要：对常见正极材料的热稳定性进行了综述,通过对正极材料的DSC数据的比较,可见表面包覆可以提高正极材料的热稳定性,原因是包覆材料能有效抑制活性材料和电解液的直接接触,减少热量的产生,提高电池的安全性。Thermal stability of common anode materials was reviewed. The differential scanning calorimetry（DSC） data showed that the coated materials had better performance compared with the bare. The enhancements were due to the presence of stable coating layer,which effectively suppressed directly contact of the active material with the electrolyte and decreased decomposition reactions of electrolyte. The safety of battery was improved.
