Embodiment 1
[0025] Li2CO3 (99.73%), GeO2 (99.8%), BaCO3 (99.8%), FeC2O4.2H2O (99.06%), NH4H2PO4 (98%) raw materials, according to 1mol Li: 0.00002mol Ge: 0.0003mol Ba: 1mol Fe: 1mol P After proportional mixing, high-speed ball milling (rotating speed 200r / min) in absolute ethanol (AR) medium for 20h. After drying at 105-120°C, the precursor is obtained, and the dried precursor is placed in a high-temperature furnace, and calcined at 500-750°C for 24 hours in an ordinary pure nitrogen (>99.5%) atmosphere. That is, the germanium and barium activated lithium iron phosphate cathode material of the present invention is obtained.
