A wireless system uses the same power as a cell phone to safely transmit energy to chips the size of a grain of rice. The technology paves the way for new "electroceutical" devices to treat illness or alleviate pain.The central discovery is an engineering breakthrough that creates a...

A new nanomaterial could extend the lifespan of lithium-sulfur batteries, and therefore the driving range of electric vehicles.Pacific Northwest National Laboratory researchers added the powder to the battery's cathode to capture problematic polysulfides that usually cause lithium-sulfur...

Scientists at the Department of Energy's Oak Ridge National Laboratory have designed and tested an all-solid lithium-sulfur battery with approximately four times the energy density of conventional lithium-ion technologies that power today's electronics. The ORNL battery design, which...

Lithium ion batteries are at the energetic heart of almost all things tech, from cell phones to tablets to electric vehicles. That’s because they are a proven technology, light, long-lasting and powerful. But they aren’t perfect.

Research conducted with a large new battery could help make the Northwest's and the nation's electric system smarter and more efficient. Portland General Electric's 5-megawatt, lithium-ion energy storage system is part of PGE's contribution to the Battelle-led Pacific Northwest Smart Grid Demonstration...

Anyone who owns an electronic device knows that lithium ion batteries could work better and last longer. Now, scientists examining battery materials on the nano-scale reveal how nickel forms a physical barrier that impedes the shuttling of lithium ions in the electrode, reducing how...

According to Steven Arnold Klankowski, a doctoral candidate in chemistry at Kansas State University, sometimes even batteries can use a boost of energy. Klankowski is working under Jun Li, professor of chemistry, to develop new materials that could be used in future lithium-ion...
