Sodium-ion batteries (SIBs) are regarded as promising low-cost alternatives to the prevailing lithium-ion batteries. However, most anode materials for SIBs suffer from low initial coulombic efficiency (ICE), limiting their commercial applications. Herein, we demonstrate a Na-ion anode with an extrem...
