Researchers at ORNL demonstrated that sodium-ion batteries can serve as a low-cost, high performance substitute for rechargeable lithium-ion batteries commonly used in robotics, power tools, and grid-scale energy storage.
![Closely spaced hydrogen atoms could facilitate superconductivity in ambient conditions](/sites/default/files/styles/list_page_thumbnail/public/2020-02/Closely_spaced_hydrogen_atoms-correct.png?h=6a4c2577&itok=GBnxpWls)
An international team of researchers has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted for decades — a feature that could possibly facilitate superconductivity at or near room temperature and pressure.
