Lithium-ion batteries are used in various electronic devices. But, they also come with potential hazards, particularly if the battery is damaged or overcharged. This usually occurs because, in its overcharged state, spiky structures called 'lithium dendrites' get deposited in the battery. Now, scientists use a technique called 'operando nuclear magnetic resonance' to track the precise mechanism of dendrite formation. They also extend their experiments to sodium-ion batteries, making their practical application easier.
