Dynamic Electrochemical Action of Low Temperature Plasma Exposed NaFePO4/Activated BCC Nanocomposites in Cathode Applications

Abstract

In this research, we designed a high performance cathode materials for sodium-ion batteries derived from cold plasma exposed NaFePO4/activated bamboo charcoal (BCC). XRD, FTIR, FESEM, and Brunauer–Emmett–Teller (BET) were used to examine the crystal structure, functional groups, morphological features, and surface area of the composites. The material's surface characteristics, such as wettability, adhesion, and conductivity analysis, were proved, and the energy storage capacity of the material and these characteristics were magnified by exposure to DC glow discharge plasma. In this work, the NaFePO4/activated BCC was subjected to DC glow discharge plasma with various plasma producing gases. The electrochemical investigation shows that the air plasma-treated composite produces the best results when compared to the untreated sample. The enhancement of the diffusivity of the composite reveals that the plasma-treated materials are appropriate for energy storage devices.
