Researchers in China have used electrochemical impedance spectroscopy to analyze the state of health of sodium-ion batteries.

The work focused on two-phase composites, which are commonly used in solid-state batteries, using Li 7 La 3 Zr 2 O 12 -LiCoO 2 as a model system.

Researchers are working to enhance battery safety and efficiency by developing solid-state alternatives to lithium-ion batteries. These batteries offer improved energy efficiency and safety, but a ...
