Building a better battery

A new battery technology provides double the energy storage at lower cost than the batteries that are used in handheld electronics, electric vehicles, aerospace and defence.

'Yolk-shell' design leads to world-record battery performance

(Phys.org)—SLAC and Stanford scientists have set a world record for energy storage, using a clever "yolk-shell" design to store five times more energy in the sulfur cathode of a rechargeable lithium-ion battery than is ...

Researchers probe invisible vacancies in fuel cell materials

(Phys.org) -- Knowing the position of missing oxygen atoms could be the key to cheaper solid oxide fuel cells with longer lifetimes. New microscopy research from the Department of Energy's Oak Ridge National Laboratory is ...

Scientists make nontoxic, bendable nanosheets

(Phys.org) -- Cornell materials scientists have developed an inexpensive, environmentally friendly way of synthesizing oxide crystal sheets, just nanometers thick, which have useful properties for electronics and alternative ...

Nanostructured electrodes for rechargeable sodium-Ion batteries

Highly efficient 3V cathodes for rechargeable sodium-ion batteries have been developed by users from Argonne National Laboratory's Materials Science, Chemical Sciences & Engineering, and X-ray Sciences Divisions, as well ...

A systematic way to find battery materials

Lithium-ion batteries have become a leading energy source for everything from smartphones and laptops to power tools and electric cars, and researchers around the world are actively seeking ways to nudge their performance ...
