An international team of researchers (Sweden, Denmark, Switzerland) succeeded in observing how the lithium metal in the cell behaves as it charges and discharges. They developed an operando synchrotron X-ray tomographic microscopy method capable of probing in real-time the formation, growth, and dissolution of Li microstructures during the cycling of a Li||Cu cell containing a standard non-aqueous liquid electrolyte solution. This enabled tracking the evolution of deposited Li metal as a function of time and applied current density and distinguishing the formation of electrochemically inactive Li from the active bulk of Li microstructures. Now the team aims to test the technique on other battery concepts. The new method may contribute to batteries with higher capacity and increased safety in the future cars and devices… read more.
