Battery technology of the future
Sodium is one of the most abundant elements on Earth and is best known as a component of salt. Unlike lithium, it can be extracted in large quantities worldwide in an environmentally friendly way. Thanks to state-of-the-art technology, sodium is now also used in batteries – with maximum safety and an energy density comparable to lithium iron phosphate batteries. Battery storage is key to a successful energy transition. Increase your self-consumption, reduce your electricity costs, and become more independent from the grid.

Discover Salzstrom in the video
In this video, YouTuber Norio introduces Salzstrom and the sodium-ion battery R2—an innovative solution for safe and sustainable energy storage. The Vienna-based startup is positioning its sodium-ion technology as a European alternative to conventional lithium batteries, demonstrating how modern energy storage solutions can operate reliably even under demanding conditions.
Discover what makes the R2 sodium-ion battery stand out, why safety and sustainability are at the core, and what role Salzstrom aims to play in the future of energy storage.

Your benefits
Unique Safety
Salt batteries offer an exceptionally low fire risk, as their inherently stable and less reactive materials make them far less susceptible to faults — a distinct advantage over lithium batteries.
Long-lasting & eco-friendly
Salt batteries eliminate the need for scarce elements such as lithium, cobalt, or nickel. The unparalleled life-span (over 10,000 charging cycles) protects the environment.
Salt batteries store electricity in a particularly sustainable way.
Operates as low as -30°C.
Discharge is possible at temperatures as low as -30°C while maintaining 80% of performance. Charging is feasible down to -20°C, making salt batteries an excellent choice for cold regions. They can be easily installed outdoors in a suitable rack.
