Elastic Graphene‐Shell Architectures Enable Stress Regulation in High‐Capacity Lithium‐Ion Battery Electrodes

Advanced Science, EarlyView.
In this study, we developed elastic hollow graphene spheres (GS) that serve as a pore‐engineering additive. This strategy enables the direct fabrication of porous electrodes, effectively mitigating volume expansion and mechanical stress in silicon‐based anodes during cycling without compromising active material or increasing production costs.
