Fast Li Replenishment Channels‐Assisted Recycling of Degraded Layered Cathodes with Enhanced Cycling Performance and Thermal Stability

The direct recycling of cathode materials in lithium-ion batteries is important for environmental protection and resource conservation. The key regeneration processes are composition replenishment and atom rearrangement, both of which depend on the migration and diffusion of atoms. However, for the direct recycling of degraded LiNi
