Block copolymer electrolytes for solid-state batteries

Applications: Solid State Battery, Electrolytes, Cathodes, Polymers

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

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.
