Multifunctional polymer electrolyte improving stability of electrode-electrolyte interface in lithium metal battery under high voltage

High-voltage lithium (Li) metal batteries are promising high-performance energy storage systems. However, their practical applications are troubled by unstable electrode-electrolyte interface, the narrow electrochemical window and unsafety of liquid electrolyte. Here, a multifunctional asymmetrical gel polymer electrolyte (a-GPE) with gradient structure is proposed to address the mentioned above issues. The host of a-GPE is consisted of the...
