Block copolymer electrolytes for solid-state batteries

Oxford scientists have developed novel block copolymers electrolytes with exceptional performance for solid state battery composite cathodes.

Applications: Solid State Battery, Electrolytes, Cathodes, Polymers

Features	Benefits
Designed with a specific combination of electrochemical, mechanical, and chemical properties	Overcomes the challenges limiting practical all-solid-state batteries; Polymers demonstrate excellent ambient ionic conductivity, lithium-ion transport, oxidative stability, and elastomeric/plastomer properties
Developed with significantly improved elastomeric mechanical and adhesion properties within cathode composite	Maintains physical particle-particle contact of the solid components without applying unpractical high pressures; Overcomes composite cathodes battery longevity concerns associated with active particle volume changes occurring on charge/discharge
Developed for solid state battery capacity requirements	Greater capacity retention than equivalent cells featuring commercial polyelectrolytes; Better performance than current PFAs polymer binders
