Polymer materials are ubiquitous in current battery technology and are commonly used as binders, separators and packaging. Poly(ethylene oxide) (PEO) was first discovered to dissolve Li salts in 1973, making its use as an electrolyte possible. Today, it is still one of the most intensely studied and widely used polymer electrolytes; however, the conductivity is several orders of magnitude lower than inorganic solid electrolytes. This easy-to-synthesize, polymer electrolyte has the potential to be a superior candidate to present-day inorganic solid electrolytes. We will report the properties of a breakthrough polymer technology with a new Li⁺ conduction mechanism that does not rely on chain-segmental motion as with PEO. This new polymer electrolyte supports high-Li⁺-conductivity while maintaining a wide electrochemical window. We will present the performance of this electrolyte with a wide variety of anodes and cathodes.
