Natural karaya gum as an excellent binder for silicon-based anodes in high-performance lithium-ion batteries

Abstract

Natural karaya gum (KG), composed of polysaccharides and glycoproteins, is investigated as a binder for high-performance silicon-based anodes. Good mechanical properties provided by the multi-branched structure and glycoproteins and superior binding strength resulting from plentiful polar function groups lead to superior electrochemical performance of KG electrodes.
