IISc researchers discover how to make solid-state batteries last longer, charge faster

In a breakthrough, researchers at the Indian Institute of Science (IISc) and their collaborators have discovered how next-generation solid-state batteries fail and devised a novel strategy to make these batteries last longer and charge faster.

They say that solid-state batteries are poised to replace lithium-ion batteries that are found in almost every portable electronic device. The researchers state that on repeated or excessive use, they develop thin filaments called ‘dendrites’ which can short-circuit the batteries and render them useless.

In a new study published in ‘Nature Materials’ journal, they have identified the root cause of this dendrite formation – the appearance of microscopic voids in one of the electrodes early on.
