| 摘要 |
A non-aqueous electrolyte cell includes a cathode containing a cathode active material, which is mainly composed of a compound represented by the general formula LixFePO4, where 0 < x ≤ 1, with the molar ratio of Li3PO4 to a compound represented by the general formula LixFePO4, which ratio is represented by Li3PO4/LiFePO4, being Li3PO4/LiFePO4 ≤ 6.67 x 10<-2>. <??>Starting materials for the synthesis of compound LixFePO4 where 0 < x ≤ 1 are Li3PO4 and Fe3(PO4)2 or Fe3(PO4)2nH2O when n denotes a number of hydrates. |
