An ultra-stable anode material for high/low-temperature workable super-fast charging sodium-ion batteries

An ideal rechargeable battery will possess the merits of high specific capacity, long cycling stability, short charging time, high initial coulombic efficiency, wide working temperature range, and low cost. Sodium-ion batteries (SIBs) are expected as the next generation of energy storage devices, but achieving the above features is still a major challenge. Herein, we have developed the 3D hierarchical FeSe2/rGO hybrids by a rational hydrothermal...
