新型粘结剂海藻酸钠在锂硫电池中的应用研究
Study on sodium alginate as a binder for lithium-sulfur batteries
摘要
Abstract
Sodium alginate was employed as binder of positive electrode for lithium-sulfur battery.Electrochemical stability of sodium alginate and structure,morphology and electrochemical properties of the sulfur cathode with sodium alginate as binder were investigated via CV,El,SEM methods.The results show that the electrochemical stability window of the sodium alginate is 1-5 V,structure and morphology of composite sulfur cathode is stable during charge-discharge,the impedance of the cathode is decreased by 34.8％ and charge-discharge and cycle performance are also significantly improved compared with the commonly used polyvinyl fluoride (PVDF) binder.关键词
