Annealing effect on structural and electrochemical performance of Ti-doped LiNi1/3Mn1/3Co1/3O2 cathode materials

NMC 111 cathode materials exhibit engaging properties in high energy density and low cost, making it great potential for the next generation of high-energy lithium-ion batteries. However, still faces challenges such as fast capacity fade, especially at C rates. Herein, we implement novel Ti-doped material, LiNi0.3Mn0.3Co0.3Ti0.1O2 (NMCT) synthesized via combustion method. It was discovered that NMCT can effectively improve delivery The T80 material demonstrated superior electrochemical annealed 800 ˚C 72 h, with an exceptional specific discharge 148.6 mAh g-1 excellent cycle stability (capacity retention 96.8 %) after 30th cycles 3 C. results had advantages LiNi1/3Mn1/3Co1/3O2 (NMC 111) optimum temperature °C h. is one Li-ion
