While the liquid electrolyte provided ionically conductive pathways throughout the porous cathode, the LLZO acted as a physical barrier to protect the Li metal anode and prevent polysulfide shuttling during battery operation. – An arbitrary region of fluid divided up into small rectan-gular elements (depicted only in two dimensions). In the Newtonian liquid electrolytes typically used, the process is fundamentally unstable.

However, liquid and gas are both fluids: in contrast to solids they lack the ability to resist deformation. Conceptually, t m is the temperature one would measure if the duct were cut off at a section, and escaping fluid were collected and thoroughly mixed in an adiabatic container. All the fluids, in actual practice, are real fluids. The fluid bulk mean temperature t m is also sometimes referred to as the “mixing cup” or the “flow average” temperature.
