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

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