The secret behind Natron's sodium-ion batteries is our patented use of Prussian blue electrodes. Prussian blue, when combined with sodium ions, creates a chemistry that delivers super-fast charging and power delivery, with no friction. It’s that lack of friction that enables our batteries to last much longer (over 50,000 cycles). And it creates a battery that’s incapable of thermal runaway, incredibly safe, and made entirely from abundant and readily available resources.
