This paper aims to critically assess the potential of biomass-derived carbon material for battery development, with a particular emphasis towards electric vehicles (EV) application. Existing studies highlighted that pretreatment, carbonization, activation and conductive dopants, influenced pore size, surface area, conductivity and degree of graphitization of carbon material, which subsequently influenced the energy density and lifecycles of battery which are essential for EV application. However, limited emphasis on electrochemical characterization of batteries at actual operational temperatures for EV presents challenge for their utilization. Also, limited information on self-discharging which is a critical factor affecting battery material properties, hinders observation of material degradation at elevated temperatures and the decline in capacity, both crucial for EV application. While change in electrochemical stability and battery conductivity remained the focus for researchers, long life cycle, high energy density and low cost were achieved without considering production and process optimization for scalability and actual operating condition of battery for EV application. Future research should prioritize optimizing synthesis processes to enhance the performance of biomass-derived carbon. Exploring various biomass types, adjusting pyrolysis and activation temperatures and employing chemical activation are essential steps to improve battery properties and meet the stringent demands of EV application. •Prospects of biomass-derived electrode for electric vehicle battery.•Carbon synthesis via biomass pretreatment, carbonization and activation.•Biomass-derived carbon enhanced electrochemical properties of electrodes.•Limited data on biomass-based battery properties at EV operating temperatures.•Lack data on self-discharging on electrochemical properties of biomass-based battery.
