Hollow LiMn2O4 nanocones as superior cathode materials for lithium-ion batteries with enhanced power and cycle performances

Single-crystalline LiMn2O4 hollow nanocones are synthesized via a template-engaged low-temperature lithiation reaction. When applied as cathode materials for lithium-ion batteries, they can deliver a high specific capacity of 127.1 mAh g-1 at 0.1 C and the capacity still maintains 100 mAh g-1 even at 50 °C. After over 1000 cycles at 5 °C, 94.8% of the initial capacity is retained
