Abstract
Li–air batteries have attracted a great deal of attention in the recent past because of their large theoretical specific energy density, but the challenges with the liquid electrolytes are the major issue for the development of practical utilization of Li–air batteries. In particular, the decomposition of non-aqueous organic electrolyte and its severe side reaction with the discharge product (Li2O2) is one of the major problems. Replacing the liquid non-aqueous organic electrolyte with a solid-state electrolyte can solve the issues. Additionally, the flammability and the environmental hazard of the liquid organic electrolytes are also major obstacle for successful commercialization of this battery. The solid-state electrolytes (including inorganic, polymer and composite electrolytes) are considered to be stable and compatible with the discharge product (Li2O2), have potential to develop a safe and environment friendly efficient Li-air batteries. In this proposal, we develop solid-state Li-air battery with composite polymer electrolyte for the commercial applications.
