Tiamat's Na-ion power battery cell is responding to unsatisfied power needs thanks to its unique and patented Na-based active raw material. Offering superior safety compared to reference technologies, Tiamat's battery cell is also offering a long cycle life. These features allow (for example) automotive makers to reach CO2 emission targets by hybridising their Internal Combustion Engine vehicles with low voltage cost effective solutions. Using Tiamat's Na-ion cell allows better CO2 reductions by taking advantage of the unmatched high power offered by this technology. Finally, using a widely available raw material in Europe cuts the need to use rare earth minerals mined and shipped from many thousands of miles away, not only reducing emissions but increasing resource security.
