P2 cathode sodium-ion battery positive electrode with 93.50% active material proportion and 3.63mg/cm² current collector areal density in P2 type crystal structure
Sodium nickel manganese titanium oxide (NaNiMnTiOx), single/double-sided coating, mass production battery grade, customizable
Crystal Structure (P2 Type)
Features a layered structure where transition metals (M/T) and oxygen atoms form a close-packed framework with sodium ions located in the layered gaps. The “P” denotes trigonal prismatic coordination of sodium ion sites, while “2” indicates two layers of transition metal-oxygen layers per unit cell.
Key Properties
- High Operating Voltage: ~3.6 V average voltage when containing the Mn³⁺/Mn⁴⁺ redox couple
- Excellent Rate Performance: P2 structure’s two-dimensional diffusion channels enable rapid sodium ion migration for fast charging/discharging
- High Theoretical Capacity: Delivers substantial reversible capacity through redox couples like Ni²⁺/Ni⁴⁺
