Executive Summary : | Lithium-ion batteries, essential in portable electronics and hybrid vehicles, contain flammable organic liquids, raising safety concerns. Recent fires in Tesla Model S and Boeing 787 Dreamliner airplanes have raised questions about their safety. Low energy density hinders the replacement of internal combustion vehicles with electric vehicles. Rechargeable lithium metal-based batteries are promising for energy storage, but their use with liquid electrolytes is limited due to dendrite formation. Various strategies have been proposed to suppress dendrite nucleation, but performance suffers due to reduced anode capacity and durability. This work aims to overcome this challenge by preparing polyethylene oxide-based solid polymer electrolytes. |
