Abstract
Solid solutions of LiMn2âXâYTiXFeYO4 (X = 0.0 ⩽ X ⩾ 0.1, Y = 0.05) nanoparticles were synthesized by urea-glycerol combustion method. The dual doped LiMn1.90Ti0.05Fe0.05O4 nanomaterial exhibits significantly improved capacity retention and much higher capacities, attributed to the more stable lattice structure, higher ion diffusion at shorter path and lower charge transfer resistance. The results of the electrochemical test demonstrate that Ti and Fe dual doping could greatly improve the cycling performance of the spinel LiMn2O4.
