The transition steel nitride skinny movie electrodes are the potential electrode supplies for the all-solid-state skinny movie lithium-ion batteries. On this examine, the orthorhombic Hf3N4 skinny movie electrodes utilized to the analysis of lithium-ion batteries had been fabricated by the magnetron sputtering deposition of Hf adopted by the N2 plasma immersion and put up annealing for the primary time. This electrode materials with out components resembling binders and conductive brokers displays excessive particular capability, excessive biking stability, and wonderful charge efficiency. At a present density of 0.1 A g-1, the preliminary discharge capability is 583.2 mA h g-1 and the secure coulombic effectivity is 96.6 %. At a excessive present density of two A g-1, the Hf3N4 skinny movie electrodes can nonetheless present a secure discharge capability of about 260 mA h g-1 and the coulombic effectivity is near 100 %. By analyzing the cyclic voltammetry curves at completely different scan charges, it’s discovered that the Li+ storage in Hf3N4 skinny movie electrodes is principally contributed by the pseudo-capacitance mechanism.
