AMBR Tech
Delivering safer, more sustainable,
and high-performing metal-based battery solutions.
Current lithium-ion batteries can be unsafe, resource-intensive, and expensive. These drawbacks arise from the flammability of organic electrolytes and unreliable lithium supply. To meet the growing demands for electrification, we need a safer, affordable, and eco-friendly energy storage solution.
Why choose us
High Safety
Instead of using flammable organic electrolytes, our technology employs fire-resistant water-based electrolytes.
Low Cost
Using water as the solvent and abundant metals as the anode, our materials are low-cost, ensuring an affordable solution.
High Performance
Our multivalent metal-based battery technology is carefully optimized to deliver high energy density.
By the Numbers
We outperform Li-ion battery technologies while using safer and cheaper materials.
