Abstract

The electrochemical properties of LiNIN electrode material were found to allow the electrode's use in lithium-ion batteries. The electrochemical properties of the electrode in lithium batteries were tested glavanostatistically against Li metal, using a rate of C/20. The chronoamperometric response of LiNiN is found to be consistent and indicates that the kinetics of the reactions are dominated by the lithium diffusion in the electrode material. A stabilization of the potential of the electrode material is found to be around 1.36 V and a current response is consistent with a two-phase mechanism. The higher amount of lithium that can be deintercalated from LiNiN is found to be associated to the increased Ni content, which can charge-compensate the reactions.
