Abstract
The need to develop an aqueous-based binder has dominated research publications for some time now. The application of this
man-made aqueous-based binder in LIBs has the potential to reduce the environmental impact of LIB. In this preliminary
study, local cassava starch is treated and prepared as a polymer binder for LIBs application. The binder is applied in lithium
nickel manganese cobalt oxide electrodes as a cathode in LIBs. The electrodes displayed a discharge capacity of 142 mAh/g
and 73 mAh/g for LiNMCO-442/Cassava starch and 139 and 28 mAh/g for LiNMCO-442/PVDF at 0.1 C-rate and 10 C-rate
respectively. After 100 cycles, the LiNMCO-442 cells retained about 80.2 and 65.5% of the cells with cassava starch binder
and PVDF binder, respectively, at room temperature. The fairly electrochemical performance of the local cassava starch
makes it a potential alternative to the petroleum-based binder, PVDF.
