As the most-studied III-nitride, theoretical researches have predicted the presence of gallium nitride (GaN) nanosheets (NSs). Herein, a facile synthesis approach is reported to prepare GaN NSs using graphene oxide (GO) as sacrificial template. As a new anode material of Li-ion battery (LIBs), GaN NSs anodes deliver the reversible discharge capacity above 600 mA h g–1 at 1.0 A g–1 after 1000 cycles, and excellent rate performance at current rates from 0.1 to 10 A g–1. These results not only extend the family of 2D materials but also facilitate their use in energy storage and other applications.
