Cathode 'defects' improve battery performance

Engineers strive to design smartphones with longer-lasting batteries, electric vehicles that can drive for hundreds of miles on a single charge, and a reliable power grid that can store renewable energy for future use. Each ...

New coating could have big implications for lithium batteries

Building a better lithium-ion battery involves addressing a myriad of factors simultaneously, from keeping the battery's cathode electrically and ionically conductive to making sure that the battery stays safe after many ...

Cause of cathode degradation identified for nickel-rich materials

A team of scientists including researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and SLAC National Accelerator Laboratory have identified the causes of degradation in a cathode material for ...

The science behind pickled battery electrolytes

Battery researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory have discovered an important chemical reaction that resembles the method used to make pickles. The reaction provides key insights into ...
