Accelerating ion/electron transport by engineering an indium-based heterostructure toward large and reversible lithium storage

Abstract

The high activity of the In₂O₃/In₂S₃ heterostructure can be activated into homogeneous In₂O_xS_3−x nanodots, thereupon stabilizing the subsequent cycles. The In₂O₃/In₂S₃ can offer a high capacity of 1140 mA h g⁻¹ at 0.1 A g⁻¹ after 290 cycles, and even at 1 A g⁻¹, it harvests a reversible capacity of 900 mA h g⁻¹ after 600 cycles.
