Sodium-Ion Technology
The Future of Energy Storage
How does a sodium-ion battery work?
Sodium-ion batteries work on the same fundamental principle as lithium-ion batteries: ions move between the anode and cathode through an electrolyte during charging and discharging.
The key difference: instead of lithium, sodium ions are used – a raw material available in virtually unlimited quantities worldwide, found in ordinary sea salt.
Advantages of Sodium-Ion Technology
Five compelling reasons why sodium-ion batteries are the future of energy storage.
Unlimited raw material supply
Environmentally friendly extraction
Independent of lithium, cobalt and nickel
Non-toxic and cost-effective
Highly recyclable

Battery Management System (BMS)
Our battery storage systems use an advanced BMS to monitor and optimize performance. They include protections for voltage, temperature, overcurrent, and insulation faults, along with real-time hazard alerts. The system supports AC integration, remote monitoring, and local display access. Safety disconnects add an extra layer of protection for reliable, compliant operation.
Economic Benefits for Companies
Reducing Energy Costs
Peak shaving reduces demand charges. Time shifting optimizes energy use.
Fast ROI
High cycle lifespan. Low maintenance. Price-stable raw materials (sodium instead of lithium).
Subsidy Eligibility & ESG Benefits
Supports sustainability goals. Improves ESG ratings. More profitable under the European Green Deal.
