A new type of lithium-metal battery reaches an extremely high energy density of 560 watt-hours per kilogram -- based on the total weight of the active materials -- with a remarkable stability.

Density functional theory (DFT) is a cornerstone tool of modern physics, chemistry, and engineering used to explore the behavior of electrons. While essential in modeling systems with many electrons, ...

The division is pretty clear: nickel-metal-hydride batteries are for use only in hybrids--at least those from Toyota, which has used more of the batteries than any other maker by far. Lithium-ion ...

Refractory metals are a class of metallic materials that offer superior heat resistance and very high melting points. While the exact definition of which elements are included in this group varies, ...

Researchers from Tohoku University and the Japan Synchrotron Radiation Research Institute produced fresh insights about the release of oxygen in lithium-ion batteries, paving the way for more robust ...
