摘要
LiFePO4作为新一代首选的正极材料,具有材料来源广泛、价格便宜、热稳定性好、比能量高、无吸湿性、对环境友好等优点。笔者综述了LiFePO4的结构特征、充放电机理、合成方法及改性研究。
LiFePO4 is a new alternative candidate material for lithium-ion batteries due to its natural abundance, low cost, high thermal stability, high special energy, no hygroscopicity and environmental friendliness etc. The structural characteristics, charge-discharge mechanism, synthesizing methods and improvement of LiFePO4 were reviewed in this paper.
