Features a layered architecture where transition metals and oxygen atoms form a close-packed framework with sodium ions positioned in the layered gaps. The "P" designation indicates trigonal prismatic coordination of sodium ion sites, while "2" represents two layers of transition metal-oxygen layers per unit cell.
- High Operating Voltage: ~3.6V average voltage utilizing Mn³⁺/Mn⁴⁺ redox couple
- Excellent Rate Performance: Two-dimensional diffusion channels enable rapid sodium ion migration for fast charging/discharging cycles
- High Theoretical Capacity: Substantial reversible capacity through redox couples including Ni²⁺/Ni⁴⁺
P2 cathode batteries deliver exceptional energy density exceeding 280Wh/kg for demanding applications. Requires storage in controlled dry, low-humidity environments to prevent performance degradation from CO₂ and H₂O reactions during charging cycles.
- Enhanced Battery Life: Minimizes delamination risks during extended cycling
- Process Compatibility: Optimized for slurry coating, calendering, and stacking manufacturing processes
- Quality Consistency: Strict ±1μm tolerance control ensures reliability for industrial-scale production
