Sodium Nickel Iron Manganese Oxide BN-O3A O3 Type Sodium Ion Battery Positive Electrode Material
O3-type NaNiFeMnO₂ (BN-O3A) is a layered transition metal oxide cathode material for sodium-ion batteries, with the general formula NaNiₓFeᵧMn₁₋ₓ₋ᵧO₂. It is characterized by its high theoretical capacity (~140 mAh/g at 0.1C), cost-effectiveness (abundant Fe/Mn resources), and structural stability. The "O3" denotes a trigonal prismatic coordination of Na⁺ ions, enabling high Na⁺ content but suffering from irreversible phase transitions during cycling.

Challenges:
Performance Optimization:
BN-O3A is a promising candidate for large-scale energy storage (e.g., grid storage, EVs) due to its low cost and compatibility with existing Li-ion battery manufacturing. Recent advances in high-entropy doping and P/O hybrid phases aim to further improve energy density (>420 Wh/kg) and cycle life (>500 cycles at 1C)
