Expectation of a scientific breakthrough for realization of a sustainable mobile society

Abstract

The development of high energy density devices produces a dramatic improvement in the cruising range of electric vehicles and significantly contributes to realizing a sustainable society. In recent years, innovative batteries, such as all-solid battery, metal-air battery and sodium-ion battery, etc., which are estimated to provide a superior battery performance better than the latest lithium-ion battery, are now being given significant attention. Meanwhile, a number of breakthroughs are required in order to achieve practical use of these innovative batteries. In this paper, we summarized the current research approaches of these innovative batteries.
