"Three-stage" model for charge storage in hard carbon anodes gains support.

The article focuses on researchers at Lomonosov Moscow State University, Skolkovo Institute of Science and Technology, and Tokyo University of Science gave support for the three-stage model of charge storage in hard carbon anodes in the paper. Topics include the hard carbon is the material most often used for the anode in sodium-ion batteries, and the Na-ion batteries are analogous to Li-ion batteries, but instead of lithium ions moving between the cathode and anode, sodium ions do so instead.
