An eco-friendly approach of designing arecanut husk ash into high performance Li ion battery anodes

Designing a facile synthesis approach for large scale production of Si based anode materials that would resist the huge volume expansion and subsequent pulverization during cycling is a major challenge that hinders their commercialization. The present paper uses a green approach for the synthesis of a Si based composite electrode material sourced from arecanut husk ash. In addition, the conventional organic electrolytes are replaced with Room Temperature Ionic liquid based solvents to improve the safety as well as stability. It was found that the anode materials exhibit an exceptional stability of 85.3 % at the end of 100 cycles when used in half cells.
