Sodium-Ion Batteries
Safe, Sustainable and Cost-Efficient Energy Storage Solutions
Overview
Interberg Sodium-Ion Batteries represent the next generation of energy storage for stationary and industrial applications. Based on the movement of sodium ions between electrodes, their operating principle is similar to lithium-ion technology, while relying on abundant, non-critical raw materials and offering enhanced safety and thermal stability.
Designed for energy storage systems (ESS), UPS, grid support and industrial power applications, sodium-ion technology complements existing battery chemistries by providing a robust, cost-competitive and future-proof alternative where energy density is not the primary constraint.

Why Sodium-Ion Technology
Key benefits include:
Abundant and low-cost raw materials
Sodium is widely available worldwide, reducing dependency on critical or geopolitically sensitive resources.
Enhanced safety profile
High overcharge tolerance, improved thermal stability and reduced risk of thermal runaway.
Excellent low-temperature performance
Reliable operation in cold environments where lithium-based batteries may suffer capacity loss.
High charge and discharge capability
Suitable for applications requiring high C-rate performance.
Lower long-term cost potential
As production volumes increase, sodium-ion battery costs are expected to decrease significantly, potentially becoming lower than LFP in large-scale deployments.
Sodium and lithium are adjacent elements in the periodic table and share similar electrochemical behavior. However, sodium offers several structural advantages that make it particularly attractive for large-scale and stationary energy storage.
Sodium-Ion vs. Lithium-Ion: A Complementary Approach
Sodium-ion batteries are not intended to replace lithium-ion in all applications, but to complement it.
