Deskripsi
Lithium-free graphite dual-ion battery offers a new means of energy storage. Here the authors show such device utilizing a highly concentrated electrolyte solution of KFSI in alkyl carbonates that exhibits a high energy density and high energy efficiency as well as an average discharge voltage of 4.7 V.
