OPERANDO EXPERIMENTS TO CHARACTERISE BRITTLE FRACTURE-LIKE EVENTS IN CERAMIC ELECTROLYTES VIA PHOTOELASTICITY

Christos AthanasiouGrand Ballroom C

Solid electrolytes at current densities that are relevant to real battery operating conditions are prove to the penetration of lithium metal protrusions, also known as “dendritic” events, that are formed during battery charging. In this work, we show via operando photoelasticity experiments that the dendritic events at high current densities can be understood by the classic Griffith - Irwin fracture theory.
