A comparative study on LiFePO4/C by in-situ coating with different carbon sources for high-performance lithium batteries

Graphic abstract: Schematic illustration of the LFP/IAC and LFP/GAC samples. In-situ hydrothermal method is used to synthesize carbon film coated LiFePO4 particles with different carbon sources (IL and glucose). It is found that the IL carbon source can produce ultra-thin carbon film of 1-2 nm, which can not only transport the Li+ with a high speed during charge-discharge process but also creates electron paths, thus improving the electrochemical performances.168
