Lithium-ion batteries

Heating up the binder

Silicon-based anodes suffer from immense volume change and cracks during battery operations, limiting cycling stability. Now, a hierarchically-ordered conductive binder network — formed in situ upon thermal treatment of anodes containing conducting polymer precursors — can improve charge-transport and mechanical properties, and thus cyclability.
