AI Customer ServiceComposite polymer electrolytes (CPEs) strike an effective balance between ionic conductivity and mechanical flexibility for lithium-ion solid-state batteries. Long-term performance, however, is limited by capacity fading after hundreds of charge and discharge cycles.
This deformation proceeds due to compressive mechanical stresses that accumulate as a result of the swelling of battery electrodes that occurs during battery operation , , , and is expected to be more severe in next generation systems employing high expansion, high capacity electrode materials , , .
