石墨烯作为导电剂在碱性锌锰电池中的应用

Application of graphene as conductive agent in alkaline Zn / MnO_2 battery

将石墨烯作为导电剂的组分,用于碱性锌锰(碱锰)电池。当导电剂占正极的质量6%时,电池的综合电性能和高温贮存性能最佳;导电剂中添加25%的石墨烯,可提高LR6电池新电和高温贮存后的电性能,且有助于改善导电剂的分散性。石墨烯作为负极添加剂,当添加量为0.1%时,电池的电性能和贮存性能最佳,尤其是大电流性能提升了7%。

Graphene was used in alkaline Zn/MnO2 battery as component of conductive agent. The comprehensive electrical performance and high temperature storage performance of battery were the best when conductive agent occurred 6% of mass of positive electrode. The electrical performance of new battery and after high temperature storage of LR6 battery was improved when 25% of graphene was added into conductive agent,the dispersion of conductive agent was improved. The electrical performance and storage performance of battery were the best when graphene was used as negative electrode additive and adding amount was 0. 1%. Especially, the heavy load performance was increased by 7%.
