Better batteries with less lithium-ion dendrites

Formations called dendrites grow in lithium-ion batteries and may continue to grow until causing an internal short circuit, which results in battery failure and possible fire. Researchers have now shown theoretically how to control or eliminate their formation. Image: Quinn Horn, Exponent.

Researchers have shown theoretically how to control or eliminate the formation of “dendrites” that cause lithium-ion batteries to fail.

A better electrolyte for lithium ion batteries

ORNL researchers developed a nanoporous solid electrolyte (bottom left and in detail on right) from a solvated precursor (top left). The material conducts ions 1,000 times faster than its natural bulk form and enables more energy-dense lithium ion batteries. Image: ORNL.

Solid nanoporous electolyte developed at ORNL could solve many of the safety concerns associated with current lithium-ion technology.
