Title: Surface/Interface Chemistry Control of Lithium Rechargeable Battery Under Extreme Conditions

Abstract

Distinguished from the mild operating conditions of lithium rechargeable batteries for traditional consumer electronics products, newly-emerging applications such as electric vehicles, electric aircraft, smart grids, and aerospace require lithium rechargeable batteries to survive and work under various extreme conditions, such as extremely low temperatures, extreme electrochemical conditions (including high current density, high voltage, etc.) The surface properties of electrode materials play an important role in interfacial reaction and battery performance. Through the controllable design and construction of the electrode surface and interface, the thermodynamic and kinetic behavior of the interfacial reaction can be effectively regulated, which is expected to solve the survival and working problems of lithium-ion batteries under extreme conditions.
