Project: Basic research on the synthesis process of iron phosphatewith coupled aging and impurity removal.

1. Increase the reaction temperature anduse micro-channel reactors to produce high-purity FePO₄nanoparticles efficiently and safely.

FePO₄ precipitationreaction is coupled with aging and purfication by increasing the reactiontemperature to 110 ℃. Micro-channel reactors are used for continuousprecipitation to ensure the uniformity of product morphology and avoid thesafety risks of hydrogen peroxide at high temperatures.

2. Synthesized FePO₄ nanoparticles have goodelectro-chemical performance.

FePO₄ synthesized at 110 ℃ in amicroreactor was used to synthesize LiFePO₄ cathode material andassembled into a button cell. The initial charging and discharging specificcapacity at a rate of 0.1C can reach 168.32 mAh/g,approaching theoretical specific capacityof FePO₄ electrode. Specific capacity decrease at high rates is lesssignificant.
