Nest‐like Silicon Nanospheres for High‐Capacity Lithium Storage

Nest-like Si nanospheres and their highly reversible lithium storage (3952 mAh g–1 at 100 mA g–1) and excellent high-rate capability (3052 mAh g–1 at 2000 mA g–1) are reported (see figure). This result suggests that the as-prepared nest-like Si nanospheres are promising candidates as the anode materials of rechargeable Li-ion batteries.
