Abstract: Superior electrochemical performance of LiMn 2 O 4 is considered to be one of the most important properties for lithium-ion batteries (LIBs). This paper presents an extremely high performance cathode material, multi-shelled LiMn 1.95 Co 0.05 O 4 cages, which are created using a sucrose template. A small amount of Co substitution uniformly in a bulk material not only tunes Mn 3+ in the minority with bulk stability improving, but can also accommodate specific capacity. In addition, the unique caged structure enhances Li + diffusion and electrolyte penetration, leading to an outstanding rate capability. The as-synthesized cathode material exhibits a very high cap acity of 154.4 mA h g -1 , and retains a high value of 136.7 mA h g -1 after 500 cycles. The present work investigated the combined effect of a tunable average Mn oxidation state and unique multi-shelled cages in a controllable aerosol process.
