The anode featured in this latest study is made up of a blend of elements – including manganese, carbon and nitrogen – that is chemically similar to the formula of the iron-containing paint pigment known as Prussian blue. Compared with the relatively mature designs of anodes used in lithium-ion batteries, anodes for sodium-ion batteries remain an active focus of R&D. The battery that Natron Energy supplied for the study features an unconventional design for an anode, which is one of its two electrodes. Scientists at Berkeley Lab and New York University participated in the study, which was led by researchers at Natron Energy, formerly Alveo Energy, a Santa Clara, California-based battery technology company. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) were key in the discovery. This direct proof of a previously unconfirmed charge state in a manganese-containing battery component could inspire new avenues of exploration for battery innovations. ![]() This chemical state, first proposed about 90 years ago, enables a high-performance, low-cost sodium-ion battery that could quickly and efficiently store and distribute energy produced by solar panels and wind turbines across the electrical grid. Scientists have discovered a novel chemical state of the element manganese.
