Resting found to boost performance of lithium metal batteries
Next-generation electric vehicles could run on lithium metal batteries that go 500 to 700 miles on a single charge, twice the range of conventional lithium-ion batteries in EVs today.
EVs that go 1,000 kilometers on a single charge: New gel may make it possible
Futuristic advancements in AI and health care stole the limelight at the tech extravaganza Consumer Electronics Show (CES) 2024. However, battery technology is the game-changer at the heart of these innovations, enabling greater power efficiency. Importantly, electric vehicles are where this...
Getting to know the 'ghost' inside batteries: An in-depth examination of tiny short-circuits
An Argonne team developing materials for solid-state batteries has taken an unexpected detour to investigate tiny short-circuits known as soft-shorts. Their insights will benefit battery researchers around the world.
Deciphering the deep dynamics of electric charge
Research led by Oak Ridge National Laboratory's Marti Checa and Liam Collins has pioneered a groundbreaking approach, described in the journal Nature Communications, toward understanding the behavior of an electric charge at the microscopic level.
Researchers raise expectations for commercialization of high-energy-density all-solid-state batteries
Researchers are actively working on non-flammable solid electrolytes as a safer alternative to liquid electrolytes commonly found in lithium-ion batteries, which are vulnerable to fires and explosions.
Chemists decipher reaction process that could improve lithium-sulfur batteries
Lithium-sulfur batteries can potentially store five to 10 times more energy than current state-of-the-art lithium-ion batteries at much lower cost. Current lithium-ion batteries use cobalt oxide as the cathode, an expensive mineral mined in ways that harm people and the environment...
Self-extinguishing batteries could reduce the risk of deadly and costly battery fires
In a newly published study in Nature Sustainability, we describe our design for a self-extinguishing rechargeable battery. It replaces the most commonly used electrolyte, which is highly combustible—a medium composed of a lithium salt and an organic solvent—with materials found in a commercial...
Machine learning techniques enhance the discovery of excited nuclear levels in sulfur-38
Fixed numbers of protons and neutrons—the building blocks of nuclei—can rearrange themselves within a single nucleus. The products of this reshuffling include electromagnetic (gamma ray) transitions. These transitions connect excited energy levels called quantum levels, and the pattern in these...
