Multi-scale boron penetration toward stabilizing nickel-rich cathode.

ABSTRACT: Nickel-rich layered oxides LiNi _x Co _y Mn_{1- x - y} O₂ (x ≥ 0.8) have been recognized as the preferred cathode materials to develop lithium-ion batteries with high energy density (>300 Wh kg^-1). However, the poor cycling stability and rate capability stemming from intergranular cracks and sluggish kinetics hinder their commercialization. To address such issues, a multi-scale boron penetration strategy is designed and applied on the polycrystalline LiNi_0.83Co_0.11Mn_0.06O₂ particles that are pre-treated with pore construction. The lithium-ion conductive lithium borate in grain gaps functions as the grain binder that can bear the s
