This work first pioneers the synthesis of trigonal [[EQUATION]] thin film assisted by the N2 plasma treatment and systematically investigates its Li+ storage properties by using both of the theoretical and experimental approaches. theoretical calculations reveal that the (001) plane of [[EQUATION]] thin-film electrode with a large diffusion coefficient of Li+ (~7.5 × 10-10 m2 s-1) is preferential for the adsorption and diffusion of Li+. The specific capacity of ~590 mA h g-1 with a Coulombic efficiency higher than 99% could be accomplished by the [[EQUATION]] thin-film electrode at the current density of 0.1 A g-1 after 100 cycles. Notably, the specific capacity is gradually increased to 600 mA h g-1 at the high current density of 1 A g-1 after 300 cycles. It is demonstrated that the [[EQUATION]] thin-film electrode possesses the fast charge-discharge capability due to its large diffusion coefficient of Li+. The Li+ storage mechanism of [[EQUATION]] thin-film electrode is associated with the intercalation of Li+ and conversion. These results show that the N2 plasma treatment opens up an avenue to fabricate the thin-film nitrides with unusual phases as the anode materials of lithium-ion batteries for the development of all-solid-state thin-film batteries in the future.
