Electrochemical Performance of NaNiCoMnO2 for Cathode Material in Sodium Ion Batteries

Abstract

Lithium ion batteries have emerged as the best suited power source for portable electronics. They are also being considered as strong contenders to meet the energy demands of the transport sector. However lithium cannot be considered as an abundant element and its natural resources are unevenly distributed. Sodium-ion batteries (NIB) appear as a promising alternative to the well-established lithium batteries technology. Sodium natural resources are unlimited everywhere as sodium is the fourth most abundant element on earth. Layered sodium transition metal oxides, NaxMO2 (M = transition metals), appear as very interesting cathode materials. The interest in these layered oxides probably arose from their high capacities and ease of synthesis In this study, we synthesized NaNiCoMnO2 as the cathode material and its electrochemical performance was measured. Also the Na ion intercalation and deintercalation behavior was studied using Galvanostatic Intermittent Titration Technique(GITT) and Cyclic voltammetry (CV)
