The other electrode, called a cathode, contains copper, nitrogen, carbon, and iron. “Typically, in lithium-ion and sodium-ion batteries, the anode is more often carbon-based,” said Wanli Yang a staff scientist at Berkeley Lab’s Advanced Light Source (ALS), a source of X-rays that were used in the battery experiments.īut in this case, both of the battery’s electrodes utilize the same type of materials based on elements known as “transition metals” that are useful in chemistry because they can exhibit various charged states. X-ray experiments were conducted at Berkeley Lab, the results of which were published on Februin the journal Nature Communications. The anodes were 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 samples were supplied by Natron Energy, and featured a unique design for an anode, which is one of its two electrodes. Researchers at Natron Energy, formerly Alveo Energy, a Palo Alto, California-based battery technology company led this study in collaboration with scientists from Berkeley Lab and New York University. This evidence of a previously unconfirmed charge state in a manganese-containing battery component could also inspire new avenues of exploration for battery innovations. This chemical state 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. (PRWEB) March 05, 2018Ī collaboration between Natron Energy and scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and New York University has resulted in the discovery of a novel chemical state of the element manganese – first proposed about 90 years ago.
