... at the optimum temperature range. Here, the effects of three distinct (natural convection, forced convection, and tab cooling) methodology were experimentally compared at both the cell and module levels (six serial 7.5 Ah Kokam pouch cells, 1P6S) for thermal management of lithium-ion cells. The experiments were...

... . This effective roughness value should be viewed as a measure of the complex contact line pinning behavior on the CuO nanostructures rather than an absolute measure of the roughness [ 26 ]. Global droplet nucleation and growth behavior was studied with optical microscopy using a custom built experimental...
