Cobalt-free electrodes achieved with nickel ions

Yokohama National University Many electric vehicles are powered by lithium-ion batteries that rely on cobalt — a scarce, expensive metal with high environmental and social...

A battery’s hopping ions remember where they’ve been

Seen in atomic detail, the seemingly smooth flow of ions through a battery’s electrolyte is surprisingly complicated. Solid-state batteries store and release charge by nudging...

Researchers have shed important new light on what the early signs of battery failure look like

Argonne researchers complete an in-depth examination of soft-shorts, a phenomenon that is an early step toward permanent failure in a battery DOE/Argonne National Laboratory An Argonne...

Self-extinguishing batteries could reduce the risk of deadly and costly battery fires

Apparao Rao, Clemson University and Bingan Lu, Hunan University In a newly published study, we describe our design for a self-extinguishing rechargeable battery. It replaces...

Cobalt-free batteries: MIT chemists developed a battery cathode based on organic materials

Many electric vehicles are powered by batteries that contain cobalt — a metal that carries high financial, environmental, and social costs. MIT researchers have now...

Solid state battery design charges in minutes, lasts for thousands of cycles

Research paves the way for better lithium metal batteries Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed...

Investigation of degradation mechanism for all-solid-state batteries takes another step toward commercialization

New findings reveal how degradation of all-solid-state batteries occurs at the cathode under low-pressure operation. Clues to accelerate commercialization of all-solid-state batteries. National Research Council...

AI networks are more vulnerable to malicious attacks than previously thought

North Carolina State University Artificial intelligence tools hold promise for applications ranging from autonomous vehicles to the interpretation of medical images. However, a new study...

Researchers extend non-line-of-sight imaging towards longer wavelengths

Emerging technologies for non-line-of-sight imaging can detect objects even if they are around a corner or behind a wall. In new work, researchers use...

Greener solution powers new method for lithium-ion battery recycling

Used lithium-ion batteries from cell phones, laptops and a growing number of electric vehicles are piling up, but options for recycling them remain limited...
