Sodium-ion batteries
Explore sodium-ion cells and starter-system paths with clear compatibility, documentation, and shipping guidance.
Shop sodium-ion
Open each SKU for the exact specifications, included quantity options, current qualification status, and complete-system guidance.
Available product path
U.S.-stock 32140 sodium-ion cell with a clear single-cell and four-cell builder path for testing, education, and documented DIY projects.
Available product path
Three individual U.S.-stock 46145 3.0V 20Ah sodium-ion cells remain. Multi-cell sets are sold out; join the free next-batch priority list for 4, 8, 16 or 32 cells.
Development only
Large-format sodium-ion cell retained for technical review while its exact-model electrical specification, documentation, included hardware, QC evidence, and shipping path are reconciled.
Best applications
Evaluate cranking performance, charging voltage, vehicle compatibility, temperature data, and warranty.
Review the exact supplier temperature curves. Do not assume every sodium-ion model performs the same.
Useful for learning, cell testing, small packs, research, and emerging-chemistry projects.
Possible only when the BMS, charger, voltage range, inverter, documents, and shipping path all align.
LFP or sodium-ion?
| Buyer priority | LiFePO4 | Sodium-ion |
|---|---|---|
| Established DIY ecosystem | Strong | Developing |
| BMS and inverter availability | Broad selection | Must confirm voltage compatibility |
| Energy density | Generally stronger | Application dependent |
| Cold-weather interest | Charging limits require attention | Potential advantage on supported models |
| Best choice for most first-time builders | Usually the easier starting point | Best for informed pilot applications |
