In the present work, uniform GaOOH nanorods have been successfully synthesized <i>via</i> a simple hydrothermal method and employed as an anode material for LIBs for the first time. The obtained GaOOH nanorods show a high-purity phase with an average length of ∼1.4 μm and a width of ∼100 nm. As an anode, it delivers a stable capacity of ∼1089 mA h g^-1 at a 0.5 A g^-1 current density upon 300 cycles and a high rate capacity of ∼639 mA h g^-1 at 2 A g^-1, where the pseudocapacitance plays a dominant role with a capacity contribution ratio of about 83% at 2.0 mV s^-1. This enhanced storage performance can be attributed to a 1D nanostructure with efficient electron and ion transfer as well as strain relaxation upon multiple-cycling.RSC advancesUniform gallium oxyhydroxide nanorod anodes with superior lithium-ion storage.PMC907412451871059, 51601040, 51572948, 51671001, 51971002Fu BLi YFeng JZhang XWang FFang LSong YfalseUniform gallium oxyhydroxide nanorod anodes with superior lithium-ion storage.Exploration of a novel metal oxyhydroxide material provides potential candidates for lithium ion battery (LIB) anodes.
