Abstract

The possibility of conversion to the RC-MAT propulsion system (gasoline engine → electric motor) was studied. However, as commercial battery capacities are low. it is not possible to change the propulsion system. Nevertheless, development of nex-generation batteries is necessary for high capacity and high energy density. Although Li/S batteries are theoretically suitable as new generation batteries, these batteries are not composed of only Li and S. Hence, ensuring high energy density can be difficult. Moreover, electrolytes are important components in the study of energy density; hence, the battery by Li2S8 Molarity was sorted. There are no studied on its various electrode components. In this study, a Li/S battery was fabricated using an assorted 3D sulfur electrode of high energy density and its electrochemical properties were studied. The Li/S battery has a high energy density of 468 Wh/kg at 1.28 M Li2S8 (A805-1.28). Its capacity rapidly decreased after 1 cycle with more than 1 M Li2S8.
