Again, it's simply not. You keep acting like cost per kW is irrelevant. This is absolutely not the case. You're the one trying to hand wave away the power input and output demands of stabilizing a renewables grid. According to your logic, people would never use li-ion for grid storage. Except that they actually do. In new projects it's more common than PbA for the large (greater-than-datacenter) scale (PbA still dominates at the datacenter scale, and probably will for some time to come)
I would say that you have obviously never worked with lithium batteries. Tesla does not use large format cells. It uses 18650-format cells. One never messes with individual cells, the bricks are designed to allow multiple concurrent failures without significant degradation in performance. And saying that something is "yet to be seen" does in no way shape or form mean "using defunct packs is bull", and it's beyond me how you could read that into that statement. Furthermore, it's also funny how you read that section but entirely missed the lines before it:
Considerable interest has been generated in the last 2 to 3 years for applying lithium-ion batteries for a variety of energy storage and grid stabilization (stationary) applications. Prototype systems have been installed. Megawatt scale systems typically include thousands of cells housed in shipping container-sized structures that can be situated on power utility locations. These systems usually include integrated fire suppression in their installations. Smaller systems have also been planned and are being delivered for evaluation purposes, particularly for use with renewable energy sources.
Gee, I thought nobody would want to use li-ion for grid backup?
