From Brittle to Damage-Tolerant: Particle-Level Mechanical Reinforcement Enables High-Voltage Stability in Ni-Rich Cathodes.
Mechanical degradation driven by stress accumulation and particle fracture is a critical barrier to the high-voltage operation of Ni-rich layered oxide cathodes, yet particle-level mechanical design strategies remain underdeveloped. Here, we demonstrate that coupling particle-level mechanical reinforcement with electro...
