TECHNOLOGY
A different material pathway for electrochemical storage.
Sodium-ion cells use sodium as the charge-carrying ion. The technology is being developed across the industry as an alternative chemistry for selected energy-storage applications.
If you’re evaluating energy storage for your business, your infrastructure, or your portfolio, what ultimately matters is the system level — not just the cell chemistry. That’s why this site progressively documents the cell chemistry, module architecture, battery management, safety concept and system design used by Sodium Energy. Until the underlying project data is released, our language here stays deliberately non-quantitative. Unfamiliar terms are explained in the glossary at the bottom of this page.
Batteries from salt? More precisely, from sodium, which can be extracted from ordinary table salt or from soda ash. Early research into sodium-ion batteries dates back to the 1970s and 1980s — alongside early lithium-ion research. So this isn’t a new trend; it’s a decades-old alternative chemistry that is only now becoming industrially mature.
TECHNOLOGY COMPARISON
Batteries as we know them today — and the alternative.
Sodium-ion chemistry takes a different safety and material approach than the lithium-ion systems that dominate today.
Batteries as commonly used today
- Dependence on critical materials
- Dependence on a small number of states that control access to those materials
- Thermal runaway risks must be controlled through chemistry and system design
- Explosive
- Hard to recycle
- Relatively low efficiency
The sodium-ion approach
- A significantly more widely distributed, globally available material base
- Lower dependence on any single producing country
- Potentially favourable thermal safety behaviour, depending on chemistry
- Particularly relevant for stationary and safety-critical applications
- Non-explosive
- Well recyclable
- Highly efficient
Sodium-ion cells contain no lithium, manganese, cobalt, graphite or silver — only sodium and carbon.
That lowers dependence on materials with documented environmental and human-rights risks — including child labor in cobalt mining — and on the few states that control access to them.
Raw materials other battery technologies depend on
Lithium
A soft alkali metal; comparatively scarce in industrially minable concentrations, with extraction involving significant water use and environmental impact.
Graphite
Batteries require high-purity, comparatively rare natural graphite; its mining and processing are heavily concentrated in China.
Cobalt
Economically mineable today mainly in the DR Congo, with documented environmental and human-rights risks, including child labor in artisanal mining.
Manganese
Considerably more abundant than lithium or cobalt, though extraction still carries significant local environmental impact.
Silver
A precious metal with broad industrial demand across many applications — correspondingly scarce and expensive.
Lithium-ion remains the default for automotive uses with tight space constraints, thanks to higher energy density. Sodium-ion is gaining ground elsewhere — forklifts, golf carts, and increasingly commercial vehicles.
WHY SODIUM-ION
Built around material availability and application fit.
You don’t need to commit to a single chemistry. As your storage needs grow, you benefit from a market that offers more than one technically credible material system to choose from.
Portfolio diversification
Sodium-ion adds another electrochemical option alongside established storage technologies, allowing systems to be matched more closely to application requirements.
Industrial relevance
The technology is especially relevant to markets where cost structure, resource availability, safety engineering and stationary use are evaluated as a complete system.
No race for scarce raw materials
Without lithium, cobalt, manganese or graphite, the cell chemistry is independent of the geopolitically concentrated supply chains behind those materials.
Less exposure to single-country dependence
Because sodium supply isn’t concentrated among a handful of sanction-exposed producing states, sodium-ion storage carries a lower risk of politically driven supply disruption or monopoly pricing.
Greater resilience in crisis situations
Sodium-ion cell chemistry is fundamentally more stable than lithium-ion — making sodium-ion storage the more resilient choice for safety-critical and crisis-prone environments.
SYSTEM PERSPECTIVE
Technology is more than the cell.
A credible storage product depends on engineering at cell, module, rack, control and service level. Final specifications will be published only when validated.
Cell & module architecture
Mechanical design, electrical topology and thermal strategy can be documented here once final system data is released.
Battery management
Control logic, monitoring, protection functions and operating windows belong to the system specification rather than marketing shorthand.
Safety by design
Safety concepts should be explained through architecture, testing and operating conditions. No certification or safety claim is implied by this placeholder content.
Lifecycle & service
Commissioning, diagnostics, maintenance and end-of-life strategy are integral to an industrial storage platform and will be documented as they are confirmed.

FREQUENTLY ASKED
Questions people ask us.
Direct answers to the questions that actually matter before you decide.
Is sodium-ion actually safer than lithium-ion?
Safety is created by the whole system: cell chemistry, battery management, enclosure and installation together. Cell chemistry does play a big part. Even with the best battery management and enclosure, lithium-ion cell chemistry is inherently more dangerous than sodium-ion.
What actually differs between sodium-ion and lithium-ion?
The core difference is raw materials: sodium-ion cells contain no lithium, cobalt, manganese, graphite or silver. That affects supply chain and material availability. See the Technology Comparison section for details.

How big is the sodium-ion storage market?
The global energy storage market was estimated at roughly USD 669 billion in 2024, projected to reach roughly USD 5.12 trillion by 2035 (source: BloombergNEF, gminsights.com). Sodium-ion is one of several technologies within that growing market.
What’s the difference between sodium-ion and LFP (lithium iron phosphate)?
Both are cell chemistries optimized primarily for safety and longevity rather than maximum energy density. The main difference is raw materials: LFP still requires lithium, while sodium-ion uses none at all — that affects material availability and supply chain, not necessarily every performance metric.
What is the EU Battery Passport?
The EU Battery Passport is part of the EU Battery Regulation and, from February 2027, mandates digital product records and minimum recycled-material content for certain battery categories. It primarily affects stationary and industrial storage solutions with a high lithium share in their supply chain. Sodium-ion technology is inherently easier on the environment and simpler to recycle, since it avoids scarce, high-impact materials like cobalt and natural graphite. Because sodium and carbon are abundant, sodium-ion storage is also less likely to fall under the Passport’s strictest sourcing requirements, which target chemistries dependent on critical materials.
Why do data centers need buffer storage?
Data centers are classified as critical infrastructure and require uninterrupted power. Large-scale battery storage bridges short-term grid fluctuations or outages until backup systems take over — under particularly high safety requirements for the storage technology used.
INDUSTRIALIZATION
From electrochemistry to repeatable production.
Industrial credibility depends on reproducibility, quality control, supply-chain discipline and serviceability — not on a prototype alone.
If you’re planning at the system level, a prototype isn’t enough — you want to know how reliably something is manufactured, tested and installed. We’re in active discussions with an industrial manufacturing partner. We’ll name them and share details once officially cleared for publication — until then, this section stays structured to host verified information about production stages, quality processes, rollout, installation and service.
