Presently, sustainable energy as well efficient and economical conversion storage technologies has become important work in light of the rising environmental issues dependence on portable uninterrupted power sources. Increasingly more researchers are focusing harvesting converting solar energy, mechanical vibration, waste heat, wind to electricity. Electrical play a significant role demand for green energy. Rechargeable batteries or secondary batteries, such Li-ion Na-ion Mg-ion reversibly convert between electrical chemical via redox reactions, thus storing potential their electrodes. The density rechargeable battery is determined collectively by specific capacity electrodes working voltage cell, which differential cathode anode. Over past decades, number studies have focused enhancing this capacity; however, understand manipulate electrochemical electrode materials limited. In review, material characteristics that determine influence potentials discussed. particular, electricity through intercalation reactions investigated. addition, we summarize selection criteria elements compounds effect local atomic environment discharge potential, including effects site defects, crystallinity, microstructure, using LiMn2O4, V2O5, Mo6S8, LiFePO4, LiCoO2 model samples discussion.
