X-ray tomography helps reveal how solid state batteries charge, discharge
Jan. 28 (UPI) -- With the help of X-ray tomography, scientists have for the first time observed the evolution of materials inside solid state batteries during the charging and discharging processes. The breakthrough observations -- detailed Thursday in the journal Nature Materials -- could help researchers develop more efficient solid state battery materials. Advertisement For their study, researchers used a complicated imaging technology called operando synchrotron X-ray computed microtomography to observe changes in a battery's electrode material at the interface between lithium and solid-state electrolytes. The unprecedented images showed the charge-discharge process causes voids to form at the interface, causing loss of contact between the lithium and solid-state electrolytes and trig...
