Hybrid P2/O3-Type NaNi0.26Fe0.32Mn0.42Zn0.08O2 Powder for Na-Ion Battery Cathode, 100-500 g/bottle, CSIBCHNFMZO

P2/O3 hybrid-phase layered oxides represent one of the most effective structural engineering strategies for high-performance sodium-ion battery (SIB) cathodes. By deliberately inducing a coherent intergrowth of both P2 and O3 phases within a single particle, this hybrid framework combines the best attributes of both structures while mutually suppressing their individual thermodynamic drawbacks

In a true hybrid material, the P2 and O3 phases are not simply mechanically blended; they are atomically intergrown along the c-axis within the same crystalline grain. This unique interface configuration yields two main structural advantages: (1) "Phase Pinning" Effect: During high-voltage charging (>4.1 V vs. Na+/Na), pristine P2 domains normally slide into the destructive O2 phase (causing a large ~23% volume drop), while O3 domains undergo highly irreversible structural distortions. In a hybrid lattice, the phase boundaries create localized structural strain fields. The rigid P2 domains mechanically anchor the O3 sheets, and vice versa. This mutual stabilization suppresses the collective layer sliding, locking the material into a smooth, highly reversible solid-solution reaction pathway across a wide voltage window.
