Resilient binder network with enhanced ionic conductivity for High-Areal-Capacity Si-based anodes in Lithium-Ion batteries

The rationally designed polymeric binder forms a highly stretchable network with fast self-healing ability on the Si anode which efficiently dissipates the stress of the electrode and recovers even upon significant damage. Moreover, the enhanced ionic conductivity of the binder enhances the diffusion coefficient of the Si electrode, realizing the high-rate operation of Si anodes (15 A/g).
