Natron’s batteries survive tens of thousands of deep discharge cycles, can be fully charged or discharged in just minutes, and cost significantly less than incumbent lead acid batteries.” Colin Wessells at Stanford University.Īlthough Prussian blue provides modest energy density, the startup claims that Prussian blue is so earth-available and inexpensive that it could provide a cost-effective and sustainable answer for stationary energy storage.Īccording to its website, Natron is developing batteries for “data-center UPS, electric forklifts, smart grids/microgrids, and renewables support. Natron is the former Alveo which was founded in 2012, based on work within the Huggins Group by co-founder Dr. Fluxus Ventures has also invested in the firm which has received a total of more than $50 million in venture funding and more than $5 million in ARPA-E and DOE funding. Return backers Chevron Technology Ventures, Khosla Ventures, and Prelude Ventures also participated. Natron Energy, a Santa Clara, Calif.-based startup developing a battery using Prussian blue analogue electrodes and a sodium-ion electrolyte, raised $35 million in series D funding led by ABB Technology Ventures, NanoDimension Capital and Volta Energy Technologies. We reported on battery builder Natron’s $35 million investment round last week - but wanted to provide an update on the company’s markets and technology from people familiar with the firm.
