Organic Electrode Material for Sodium-Ion Batteries

Abstract

A lot of work is done on functionalizing organic electrodes (OE) and incorporation of nanostructures to tune their electrochemical properties. In collation, OE exhibit merits like high capacity and structural design ability. Here in, organic electrodes based on their reactions are divided into three classes; C=O, C-N=O and doping reactions. The conductivity issue can be resolved through increasing conjugation. Theoretical capacity can be elevated by expanding active groups. Working voltage can be regulated by tuning grafting overseeing lowest unoccupied molecular orbital (LUMO). Future of organic electrode relies mainly on aprotic electrolyte based full NaIBs with long cycle life.
