There's an enormous amount of technical detail in this video, and VTT is a reputable organisation. I'm still unsure what to make of this. The video shows them testing a cell, not in an actual battery pack.

I'm not an expert but isn't that how a MVP works? You start at the cell level and bundle several cells later into battery.

They haven't launched an MVP. They launched a new battery as some life-changing technology - which it seems is not.
