Abstract:
Single-crystalline LiMn(2)O(4) 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.
