![]() ![]() "Now the power load on the electric grid is enormous. There are a whole bunch of chargers there and all the cars plug in at the same time," said Colin Wessells, CEO and co-founder of Natron. , which is using Natron's batteries in EV charging stations. Natron Energy, based in Silicon Valley, is also working to commercialize sodium-ion battery technology. "There's no cobalt, there's no copper, there's no lithium, there's no graphite, which is really primarily controlled by China today." Quinn said sodium-ion batteries are also safer since they can be completely discharged for transportation. ![]() "It doesn't use the expensive raw materials," said James Quinn, CEO of U.K.-based sodium-ion battery maker Faradion. For instance, the materials used in sodium-ion batteries tend to be cheaper than those in lithium-ion batteries. Sodium-ion batteries can't provide the type of range for electric vehicles offered by lithium-ion batteries, but they do present some unique advantages. Limited (CATL), revealed in 2021 that it was investing in the technology, with plans to establish a basic industrial supply chain by this year. Excitement around sodium-ion batteries picked up after the world's largest EV battery maker, Contemporary Amperex Technology Co. The technology is now getting a second look. Sodium-ion batteries have been around for decades, but large-scale development of the technology was abandoned in favor of lithium-ion batteries. In a sodium-ion battery, lithium ions are replaced with sodium ions in the battery's cathode, and lithium salts swapped for sodium salts in the electrolyte. Both battery types generate electricity through a chemical reaction and are made up of an anode, cathode, separator and an electrolyte. Sodium-ion batteries have a similar design to their lithium-ion counterparts and can be manufactured using related methods. Natron was founded as Alveo Energy in 2012 as a spin-out from research originally performed at Stanford University.Here's why sodium-ion batteries are shaping up to be a big technology breakthrough “The high-power density and fast charging time of Natron’s unique battery technology make it an attractive storage solution for the EV station of the future.” “Chevron Technology Ventures is excited about the opportunity to support Natron Energy’s development of high-performance energy storage systems,” said Jesse Teichman, who led the investment by CTV. In addition, Natron’s batteries are nonflammable during overcharge, hard short circuit, nail penetration and under external heating to over 200° C. The technology has allowed Natron to reportedly build the first battery in which chemistry does not limit the lifetime of the system, opening new opportunities for energy storage to support EV charging, renewables and industrial applications. Natron builds its batteries using commodity materials on existing cell manufacturing lines. Batteries based on Prussian blue can be fully charged and discharged tens of thousands of times at very high power. Prussian blue has a unique structure and composition that allow it to store energy much more rapidly and reversibly than other types of battery electrodes, said Natron Energy. Natron’s patented technology uses Prussian blue pigments in the positive and negative electrode of the battery. This investment provides a terrific boost to us as we develop and demonstrate energy storage products that will make fast charging stations a reality.” “We are thrilled that CTV has chosen to support Natron. ![]() As a global leader in transportation energy services, Chevron has recognized this,” said Colin Wessells, CEO at Natron Energy, Santa Clara, Calif. Widespread EV adoption depends in part on technologies that enable ubiquitous fast charging and that mitigate drivers’ range anxiety. “Vehicle electrification will be one of the defining economic trends of the next decade. Natron Energy said that, unlike the electrode materials found in most lithium ion batteries, Prussian blue benefits from widespread availability and low cost that make the batteries an economically attractive, environmentally friendly technology. Prussian blue dye, commonly used in blueprints, stores and releases energy in the form of sodium ions. ![]() Natron Energy will adapt its battery technology, originally developed for data center and utility-scale applications, to meet the power requirements of the emerging EV fast charging market. Natron Energy, a developer of new battery products using Prussian blue electrode chemistry, has closed a strategic investment by Chevron Technology Ventures (CTV) to support the development of stationary energy storage systems for demand charge management at electric vehicle (EV) charging stations. ![]()
