From: Gas Evolution in Operating Lithium-Ion Batteries Studied In Situ by Neutron Imaging

Pressure measurements on LNMO/LTO, LFP/graphite and LNMO/graphite battery cells.
Both the pressure increase and calculated gas volume are shown as a function of time. The cycling parameters were identical to those used in the neutron imaging experiments. All values were normalized to an electrode size of 2 × 4 cm2.
