Abstract:To obtain anode materials with high capacity/energy density for lithium‐ion batteries, a polyanionic compound Li2FeGeO4 is prepared, which combines the conversion‐type Fe‐based oxide and the alloy‐type Ge‐based oxide at the atomic scale. The influence of citric acid in the sol–gel process on the structure and performance of the calcined products (LFG0, LFG1, and LFG2) is investigated. The results demonstrate that citric acid does not affect the phase of Li2FeGeO4. However, with the increase of citric acid, the… Show more
