X-ray imaging reveals secrets in battery materials

In a new study, researchers explain why one particular cathode material works well at high voltages, while most other cathodes do not. The insights, published in the 19 June issue of the journal Science, could help battery ...

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 ...

Mapping battery materials with atomic precision

Lithium-ion batteries are widely used in home electronics and are now being used to power electric vehicles and store energy for the power grid. But their limited number of recharge cycles and tendency to degrade in capacity ...

Compact batteries enhanced by spontaneous silver matrix formations

In a promising lithium-based battery, the formation of a highly conductive silver matrix transforms a material otherwise plagued by low conductivity. To optimize these multi-metallic batteries—and enhance the flow of electricity—scientists ...
