Northvolt, a European EV battery and energy storage producer, has developed a state-of-the-art sodium-ion battery. The company claims the new technology is a safer, cost-effective, and more sustainable alternative to traditional battery chemistries.

The new sodium-ion battery has an energy density of over 160 watt-hours per kilogram, making it more effective than traditional nickel, manganese, and cobalt (NMC) or iron phosphate (LFP) chemistries. It uses abundant minerals, like iron and sodium, and unique materials, like a hard carbon anode and a Prussian White-based cathode. Furthermore, it doesn't contain common battery components, such as lithium, nickel, cobalt, and graphite. 

According to Northvolt, the introduction of such batteries will stimulate the broader implementation of affordable and sustainable energy storage systems globally. Developed with its research partner Altris, this technology is particularly suitable for high-temperature environments and also promotes regional manufacturing independence due to local resource utilization. Its main attraction lies in its potential to power renewable power generation and assist the global shift toward electrification.
