What Is a Sodium-Ion Battery and Why It's the Talk of 2026
This Grade A sodium-ion battery cell delivers 3.0V and 200Ah (600Wh) . it keeps 85% of its capacity at -20°C, discharges down to -40°C, and survives 5000+ cycles — the cold-weather alternative to LiFePO4 without the LTO price tag. It can be safely transported and stored at 0V, ships from our EU/PL warehouse with DDP delivery in 3–7 days, and is ideal for 24V and 48V DIY solar packs.

Cold Weather Performance: 85% Capacity at -20°C, Discharge to -40°C
FAQ
- Can a sodium-ion battery work in winter? — Yes. It retains ~85% capacity at -20°C and discharges to -40°C. This is its core advantage over LiFePO4.
- Can I mix sodium-ion cells with my LiFePO4 batteries? — No. Different voltage curves cause dangerous cross-currents on a shared DC bus.
- Why do I need a sodium-compatible inverter? — The wide 1.5–4.0V curve makes standard lithium inverters misread state of charge. Deye and Victron support sodium profiles.
- Is it safe to store a sodium battery at 0% charge? — Yes. Na-ion cells can sit at 0V without damage — safer to transport and ideal for a cabin you visit seasonally.
- Is sodium-ion cheaper than LiFePO4? — Raw materials are cheaper and prices are falling; today you pay a small premium for cold-weather performance and safety.
