Sodium Nickel Iron Manganese Oxide BN-O3A O3 Type Sodium Ion Battery Positive Electrode Material

Overview

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.

Key Features

Composition & Structure:
- Typical stoichiometry includes NaNi₁/₃Fe₁/₃Mn₁/₃O₂ (111-type) or variants like NaNi₀.₄Fe₀.₂Mn₀.₄O₂.
- Transition metals (Ni, Fe, Mn) synergize: Ni boosts capacity, Mn stabilizes structure, and Fe balances cost/performance.
Challenges:
- Irreversible phase transitions (>4.0V) lead to structural degradation.
- Air sensitivity: Reacts with moisture, forming electrochemically inactive NaOH/Na₂CO₃.
- Jahn-Teller distortion from Mn³⁺ and Ni⁴⁺-electrolyte side reactions.
Performance Optimization:
- Doping (e.g., Ti, Mg, Cu): Stabilizes structure, suppresses phase transitions, and enhances Na⁺ diffusion.
- Surface coating (e.g., Al₂O₃, NaTi₂(PO₄)₃): Mitigates electrolyte corrosion and improves cyclability.
- Morphology control: Spherical secondary particles (4–10 μm) with nano-sized primary grains enhance kinetics.

Applications & Prospects

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)
