Abstract

Recently, biomass derived carbons received great attention as a renewable source of carbon with different morphologies[1,2]. Among various carbon material preparation methods such as carbonization of polymer precursors, arc discharge, chemical vapor deposition and chemical synthesis, carbonization / hydrothermal carbonization of biomass to yield carbon looks promising due to abundant availability of precursor. A variety of biomass derived carbon materials are well studied as an electrode material for energy storage devices like lithium ion battery, supercapacitors, lithium-sulphur battery and sodium ion batteries. [1] Rice husk, tea leaves, coconut fibers, coffee shell, neem seed etc., derived activated carbons shown promising anode material for lithium ion storage. Typically, these biomass derived carbons found to be hard carbons in nature but their morphology varied with precursor material. Neem (Azadirachta indica) derived carbon was used as electrode material for supercapacitor application and shows excellent performance.[3] However, there is no study available on lithium ion intercalation in need derived carbon to the best of our knowledge. In present work, we have investigated the electrochemical performance of neem leaves derived carbon as anode material for lithium ion battery application.
