FAQs

A sodium-ion battery stores energy the same way lithium-ion does, with ions shuttling between two electrodes, but the working ion is sodium instead of lithium. Sodium is abundant and cheap, the chemistry has a very low fire risk, and it tolerates heat well. Sodion builds sodium-ion cells into 12-volt packs that drop into applications running on lead-acid today.

For most applications, yes. Sodion packs come in standard lead-acid sizes, work with automotive alternators and typical 12-volt charging systems, and connect the same way. Check the spec sheet for your tray size and charging setup, or ask us to confirm the fit.

Yes. AGM is still lead-acid chemistry, with the same weaknesses in heat and heavy cycling. Prometheus II was designed to outperform AGM in start-stop duty and tropical heat, in the same standard sizes.

Sodium-ion chemistry generally handles low temperatures better than lithium-ion, and that is one of its recognised advantages alongside heat tolerance. Rated operating ranges vary by product, so check the spec sheet for the pack you are considering, or tell us about your environment and we will advise.

Cycle life depends on depth of discharge and temperature, but in 12V replacement duty Sodion packs last 2–3× longer than typical lead-acid batteries. Warranties run up to 4 years depending on the product.

More than lead-acid upfront, less over its life. The packs last 2–3× longer and need no watering or acid maintenance, so cost per year of service typically comes out below lead-acid. Pricing depends on model and volume; request a quote and we will give you real numbers.

Sodion Energy Pte Ltd is headquartered at 75 Ayer Rajah Crescent, Singapore, and serves customers across Singapore, Southeast Asia and the Middle East. We do not hold local stock outside Singapore; supply for a project is arranged with you when we quote it. For India, our sister entity operates separately at naxione.com.

The big differences are safety and materials. Sodium-ion has a very low fire and explosion risk, so packs need far less protective engineering. The raw materials are also cheaper and easier to source than lithium.

The trade-off is energy density: sodium-ion stores less energy per kilogram, so lithium keeps winning in EVs and portable electronics. Where space and weight matter less, in stationary storage, backup power and 12V replacement, the safety and cost advantages take over.

Probably not replace. The two chemistries will coexist, each doing what it does best. The battery sodium-ion is actually coming for is lead-acid: better energy density, longer life and faster charging, without the lead. As production scales, it is hard to see what keeps lead-acid in the market.

Yes. Safety is the main reason buyers pick sodium-ion. The chemistry contains no lithium, so fire and thermal-runaway risk is very low and packs need fewer protective systems. There is no lead and no acid either, which takes the spill and fume hazards of lead-acid off the table. Our packs are built on cells tested to IEC 62619.

Very well. Sodion packs are rated to 70°C and hold runtime and cycle life in tropical heat and humidity, conditions where lead-acid degrades quickly and lithium-ion typically derates or shuts down. That is why they end up in engine bays, rooftop enclosures and outdoor cabinets.

In 12V replacement duty, Sodion sodium-ion packs last 2–3× longer than typical lead-acid batteries. Fewer replacements and lower maintenance are the main drivers of their lower total cost of ownership.

No. We buy cells from established sodium-ion cell makers and do the engineering on top: pack design, integration and application fit. That keeps us free to use the best available cell for each product instead of being tied to one factory's chemistry.

We have several patents pending on sodium-ion battery performance, covering both production and post-production stages. Some of that work runs jointly with the National University of Singapore's 2D Quantum Materials Convergence Technology Laboratory.

Contact us. We work with distributors, integration partners and investors across the region, and a short call is usually enough to tell whether there is a fit.
