摘要
锂铁磷酸盐(LiFePO4 ) 是为锂离子电池，而是低电子电导率和单个散开隧道的潜在的高效率阴极材料因为锂离子在这材料的合成期间要求好粒子尺寸和形状控制。在这份报纸，有不同尺寸和形状的六 LiFePO4 nanocrystals 成功地在乙烯乙二醇被综合了。形成 LiFePO4 nanocrystals 与的增加顺序 Fe-PO4-Li 帮助主要 { 010 } 暴露的脸，并且增加 LiOH 的数量在粒子尺寸导致减少。六个不同 LiFePO4 粒子的电气化学的表演证明最有希望的 LiFePO4 nanocrystals 任何一个有占优势 { 010 } 脸暴露或高特定的区域，用小铁(II ) 氧化。
Lithium iron phosphate （LiFePO4） is a potential high efficiency cathode material for lithium ion batteries, but the low electronic conductivity and single diffusion channel for lithium ions require good particle size and shape control during the synthesis of this material. In this paper, six LiFePO4 nanocrystals with different size and shape have been successfully synthesized in ethylene glycol. The addition sequence Fe-PO4-Li helps to form LiFePO4 nanocrystals with mostly {010} faces exposed, and increasing the amount of LiOH leads to a decrease in particle size. The electrochemical performance of the six distinct LiFePO4 particles show that the most promising LiFePO4 nanocrystals either have predominant {010} face exposure or high specific area, with little iron（II） oxidation.
