Electrolyte‐Induced Interfacial/Bulk Dual Regulation Enables Negligible Capacity Decay in Li‐Rich Cathodes

and retain 97.6% of their capacity after 400 cycles. This work provides a new pathway toward electrolyte-mediated dual stabilization and demonstrates the feasibility of mitigating capacity decay in Li-rich cathodes via electrolyte-induced interfacial/bulk regulation.
