High Performing Cathode Materials for Lithium-Ion Batteries

The storage of electrical energy in highly efficient electrode materials is very significant to achieve high energy and power density which is a key requirement for portable electronics, electrical vehicles (EVs) as well as hybrid electric vehicles (HEVs). Among the energy storage devices, Lithium Ion Batteries (LIBs) are a promising candidate can satisfy our energy demand due to its outstanding energy (~250¿730 Wh/L) and power density (~250-340 W/kg). The composition and structure of the cathode of LIBs plays a crucial role in effective lithiation and delithiation during the respective charge and discharge processes. The development of lithium-ion rechargeable batteries of high energy density has relied on the successful development of high energy density intercalation compounds (layered oxides and phopho olivines).Substitution of transition metals (in cathode materials) for other transition metals and non-transition metals has been recognized as one of the most reliable strategies to improve the energy density of LIBs.
