Influence of aloe-vera gel mediated CuO coated LiNiPO4 cathode material in rechargeable battery applications

Abstract In this work, we report the synthesis and electrochemical performance of CuO synthesized in aloe-vera gel medium coated LiNiPO4 in first time also, we compared the performance of CuO prepared in water medium coated LiNiPO4. The particle size of pure LiNiPO4 is 5.2 μm and the particle size of CuO prepared in water medium coated LiNiPO4 is 2.1μm. Also, the particle size of CuO prepared in aloe-vera gel medium coated LiNiPO4 is 1.7 μm, which is analysed by using particle size analysis. As we expected, aloe-vera gel mediated CuO effectively reduces the particle size of LiNiPO4 also it exhibits the good electrochemical performance which is examined with the help of charge/discharge analysis. Green synthesis is an operative method to prepare surface coating materials for cathode materials of lithium ion batteries.
