Energy Storage

MIT researchers have engineered a new rechargeable flow battery that does not rely on expensive membranes to generate and store electricity. The device, they say, may one day enable cheaper, large-scale energy storage.

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...

Norwegian research scientists will contribute to realizing the concept of storing electricity at the bottom of the sea. The energy will be stored with the help of high water pressure. The idea of an underwater pumped hydroelectric power plant may sound like Jules Verne fiction, but then it was...

A team of researchers from the University of Illinois at Urbana-Champaign (UIUC) and the U.S. Department of Energy's (DOE) Argonne National Laboratory are exploring ways to design batteries that heal themselves when damaged.The idea is to station tiny microspheres, each smaller than a single red blood...

Researchers at the Massachusetts Institute of Technology (MIT) developed a lightweight, inexpensive alternative to existing batteries for electric vehicles and the power grid. The new battery relies on an architecture called a semi-solid flow cell, in which solid particles are suspended in a...

A breakthrough in components for next-generation batteries could come from special materials that transform their structure to perform better over time. A team of researchers at the U.S. Department of Energy's Argonne National Laboratory, led by Argonne nanoscientist Tijana Rajh and battery expert...
