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.

For electric planes to really take off and for electric cars to travel far longer distances between charges, we'll need batteries that pack far more energy without becoming prohibitively heavy. A team ...

FORT RUCKER, Ala. -- What are heavy metals? The answer depends upon who you ask. A metallurgist would define heavy metals based upon the density of the material. A physicist would classify them by ...

Research shows promise for developing high-energy-density rechargeable lithium-metal batteries and addressing the electrochemical oxidation instability of ether-based electrolytes. Research conducted ...

Scientists in the U.S. discovered a promising new battery chemistry based on chlorine and table salt. Batteries based on this chemistry can achieve at least six times the energy density of today’s ...

Next-generation batteries could take on many forms, but one design that scientists are pinning a lot of hope on involves the use of lithium metal. The excellent energy density of this material could ...
