160Ah Sodium-Ion Cell – Industrial-Grade, Lithium-Free Power for Stationary Storage

The 160Ah sodium-ion prismatic cell is built for serious energy storage. This chemistry uses sodium instead of lithium, cobalt, or nickel, and is designed for safety, long cycle life, and cold-weather performance. It’s ideal for off-grid solar, commercial BESS racks, backup power banks, and any application where uptime matters more than watt-hours per liter.

Chemistry: NFPP (high-voltage sodium fluorophosphate polyanion cathode) paired with hard carbon anode. This system supports 3.8 V charge ceiling, 3.0 V nominal, and deep discharge to 1.5 V while delivering 6,000–10,000+ cycles.

⚡ Performance & Thermal Behavior

Low-temp discharge: Can discharge at –40 °C. Delivers ≥ 80% of rated capacity at –20 °C (1C discharge to 1.5 V after standard charge).
High-temp discharge: After soaking at 55 °C, delivers ≥ 96% of rated capacity (1C discharge to 1.5 V).
Charge retention: ≥ 90% capacity after 30 days at 25 °C. Capacity recovery ≥ 95% after recharge.
Compression spec: Designed for pack assembly under ~200–300 kgf preload to maintain performance and cycle life.

🔒 Safety & Abuse Test Results

The PORFFOR SIB-P71173208-160Ah cell passed the following abuse tests with no fire, no explosion:

Overcharge: Forced to 6.0 V @ 1C – no fire / no explosion.
Short Circuit: External short < 5 mΩ for 10 min – no fire / no explosion.
Crush: Pressed perpendicular to plates up to 200 kN or 30% deformation – no fire / no explosion.
Heat: Heated to 130 °C and held 30 min – no fire / no leakage.
Drop: 1.5 m drop onto concrete – no fire / no explosion.
Seawater immersion: Fully submerged in 3.5 wt% NaCl solution for 2 hours – no fire / no explosion.
Thermal cycling: –40 °C to 85 °C cycling (5x) – no fire / no explosion.

Translation: this chemistry is extremely hard to ignite compared to typical lithium-ion cells.

🧪 NFPP vs Layered Oxide – Which Sodium-Ion Chemistry Is This?

This cell is an NFPP fluorophosphate polyanion sodium-ion cell (high-voltage Na₃V₂(PO₄)₂F₃ cathode + hard carbon anode), not a layered oxide cell and not Prussian Blue.

Characteristic	Layered Oxide	NFPP (Polyanion)
Voltage Window	~2.0 – 4.0 V	1.5 – 3.8 V
Cycle Life	≈3,000 cycles typical	6,000–10,000+ cycles
Thermal Stability	Moderate	Very high / non-flammable behavior in abuse tests
Best Use Case	Mobility / where pack voltage and Wh/L matter	Stationary ESS, off-grid solar, backup power, telecom racks

🛠 Integration Notes (Read Before Building a Pack)

BMS required: Cell must be used under an external BMS that manages over/under-voltage, current, high temp, and active balancing between cells.
Do not charge above 3.8 V/cell. Overcharge beyond 3.8 V is prohibited.
Do not discharge below 1.5 V/cell. Going below this risks permanent damage.
Thermal design: Enclosures must manage heat and avoid hotspots. OEM is not responsible for damage caused by enclosure thermal issues.
Environmental sealing: Pack/box must be designed to meet appropriate dust/water ingress protection. Corrosion from moisture is considered integrator risk.
Mixing cells: Do not mix different part numbers or revisions in the same pack.
