제목 Electrochemical performance of silicon-alloy anodes with aqueous sodium alginate binders for Li-ion batteries
초록 The conventional PVDF binder is not an ideal candidate for high-performance Li-ion batteries due to its low adhesiveness, low mechanical strength, and poor functionality with high capacity electrode materials. In this study, the electrochemical performance with silicon alloy based anodes with alginate binders was evaluated. As a result, the anode with alginate binder exhibited significantly enhancement in the electrochemical performance, compared to the conventional PVDF binder. This improvement can be due to the higher interfacial interaction among the silicon alloy particles, the current collector, and the alginate binder. Therefore, alginate binders are promising as an anode binder for high-performance Li-ion batteries.
