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.
