The realities of batteries is that most of the cells will be at 90% capacity while a few will have dropped to 50%. So recycling really can be just plucking out the good cells and breaking down the few old cells.
Those 90% cells will also have a pretty nice degradation curve as most of the loss happens within the first few years of operating.
