Designing Adaptive Binders for Microenvironment Settings of Silicon Anode Particles

This study reports the concept of an “adaptive binder” to address the silicon anode challenge in Li‐ion batteries. Binders exhibit adaptable capabilities upon gradual changes in the microenvironments surrounding silicon particles during anodic expansion–shrinkage cycles. Long, flexible binder chains are repositioned and reoriented upon the gradual formation of Si‐micro‐environments (Si‐μ‐env) during the early battery cycles. At this stage, the...
