BTR BN-O3 Sodium-Ion NFM Cathode Material 1kg

Name: BTR BN-O3 Sodium-Ion NFM Cathode Material

Material Type: Sodium Nickel Iron Manganese Oxide (NFM) Cathode Material for Sodium-Ion Batteries

Product Code: BN-O3A / BN-O3B (two grades)

Brand: BTR

Product Introduction:

The BTR BN-O3 series is a sodium nickel iron manganese oxide (NFM) cathode material designed for sodium-ion (Na-ion) batteries, supplied in two grades — BN-O3A and BN-O3B — that share the same Na/Ni/Fe/Mn chemical composition but differ in particle size, tap density, and electrochemical performance. The material delivers 137.5–139 mAh/g first-cycle discharge capacity at 0.1C and 132–135 mAh/g at 1C in 2.0–4.0 V half cells with 1M NaPF₆ electrolyte, with 93% first-cycle efficiency and 94.5–96.5% capacity retention after 50 cycles at 1C.

Key Features:

Sodium-ion battery cathode chemistry — Na / Ni / Fe / Mn 20.7 / 17.6 / 16.7 / 16.5 wt%
0.1C reversible capacity 137.5 mAh/g (BN-O3A) and 139 mAh/g (BN-O3B)
1C reversible capacity 132.0 mAh/g (BN-O3A) and 135 mAh/g (BN-O3B)
First-cycle efficiency 93%
50-cycle capacity retention at 1C — 96.5% (BN-O3A) and 94.5% (BN-O3B)
Tap density 1.95–2.1 g/cm³ and 2-ton compaction density 2.65–2.7 g/cm³
Low specific surface area 0.5 m²/g
Low surface alkali — NaOH ≤ 0.12 wt%, Na₂CO₃ ≤ 0.45 wt%
Tested in half cells with 1M NaPF₆ in ester solvent, 2.0–4.0 V voltage window
Two grades available — BN-O3A (D50 11.0 μm) and BN-O3B (D50 11.2 μm)

Values measured by Xnergy. Typical values for reference; not guaranteed unless otherwise specified.

Shelf Life:

180 days under low humidity (less than 10% RH).

Handling & Storage:

This product is air-sensitive. Do not expose it to ambient environment for extended periods — seal the material promptly after each use, and baking before use is recommended to remove absorbed moisture. Store under low humidity (< 10% RH) to maintain the rated 180-day shelf life.

Note: Specifications listed above are typical and for reference only. Actual electrochemical performance depends on the specific cell architecture, electrolyte formulation, binder/conductive-additive composition, coating thickness, calendering parameters, formation protocol, and testing conditions. The BN-O3 series is a sodium-ion battery cathode material — formulation, electrolyte selection, and cell design considerations differ from lithium-ion NCM/LFP/LMFP cathodes; consult published sodium-ion literature and our technical team for guidance on specific Na-ion electrode protocols.
