摘要 橄榄石型磷酸铁锂(LiFePO4)用作锂离子蓄电池正极材料是当前研究热点之一,由于其高容量、高循环寿命、安全、价格低廉,无环境污染等优势,倍受人们的青睐。但其较差的导电性和低的Li+扩散系数一直是阻碍其实用化的最主要原因。从采用的方法途径、达到的电化学性能及其机制等方面综述了提高LiFePO4导电能力的国内外最新研究进展。 Olivine-type lithium ion phosphate （LiFePO4） is one of the most promising cathode materials tor rechargeable lithium batteries due to its high capacity, cyclic stability, safety, low cost and environment benignancy. However, the low electric conductibility of LiFePO4 and the low diffusion coefficient of Li-ion are the main shortcoming that prevented the realization of UFePO4 to be the cathode materials of lithium batteries. The recent research progress on the electric conductibility of UFePO4, including the route used, the electrochemistry properties achieved as well as the mechanism of the improvement of the electric conductibility were reviewed.
