From: Gas Evolution in Operating Lithium-Ion Batteries Studied In Situ by Neutron Imaging
Left: Voltage profiles of an LFP/graphite pouch cell at C/10 (first cycle) and C/2 (second cycle) rates and corresponding gas generation with time.
Prior to first discharge, the battery was kept at open-circuit potential for 30 min. Right: Neutron transmission images taken after different cycling times (indicated by the green dots) during charge and discharge.
