Nickel hexacyanoferrate (Prussian blue analogous, PBA) was synthesized by Reverse Micelle Method and was coated on LiFePO₄ cathodes to improve the performances of high rate and pulse current charge-discharge. PBA consists of a structure of low strain open framework, and exhibits a redox potential (3.4 V v.s. Li/Li⁺) similar to LiFePO₄. The PBA modified LiFePO₄ cathodes show improved high-rate capability, with a 10 C discharge capacities of 15 % higher than pristine LiFePO₄. It was found that the PBA modified LiFePO₄ can endure high pulse current charge-discharge, which is well suited for green energy grids. The modified and pristine LiFePO₄ cathodes were operated with alternate pulse currents of 0.01 C and 5 C introduced into a 0.2 C discharge/charge process to simulate the conditions of green grids. The modified LiFePO₄ cathodes exhibited capacity retention of 92% under such conditions after 50 cycles, whereas the pristine sample showed capacity retention of  only 75%. The results can be attributed to the reduction of electrode/electrolyte interface resistances due to the PBA coatings, as characterized by electrochemical impedance spectroscopy.
