説明

<p>Lithium-ion batteries (LIBs) are widely used in mobile devices and electric vehicles (EVs). One of the problems of LIBs for EV-use is inferior low-temperature performance. At low temperatures, the performance of a conventional ethylene carbonate (EC)-based electrolyte solution is degraded due to its high melting point. However, propylene carbonate (PC) that is a candidate with a low melting point cannot be used with a graphite negative electrode. In order to adapt the PC-based electrolyte solution to the graphite negative electrode, the solvation structure of lithium ions was controlled by the addition of a Lewis acid and Lewis base. In this review, the design concept of the PC-based electrolyte solution and the control of the solvation structure of lithium ions are introduced.</p>
