Utilization of Bio-waste Mussel Shell as a Decoration Material on LiCoO2 Cathode

Abstract

In this study, thermochemical conversion of mussel shells as biological waste utilizations has been made as a protection layer for cathode active materials. LiCoO2 material synthesized via sol-gel method and coated with CaO produced using mussel shells. An appropriate coating ratio enhances the cycling performance with a better specific capacity (170 mAh g-1 at 1C). Surface modification plays a crucial role in attaining an improved performance of LCO by reducing its interference between electrolytes. This study present the use of biological waste mussel shell as decoration agent for cathode active materials and lead up to decrease the amount of biological wastes.
