Li-Ion pulse discharge to improve output characteristics
The article makes it fairly clear that they aren't measuring the working capacity of the cell, but its capacity under abuse (30C in a cell not designed for high discharge) and it's down to 2% of its nominal capacity.

In that context, "pulse discharge" simply reduces the mean discharge rate to (discharge rate * duty cycle) and that "improves" capacity 8-fold, to 16% or about 1/6 of its rated capacity. As an analysis of the chemistry of the cell it's interesting, but still not very impressive.

Duty cycle appears to be 10%, inferred from the time axis (160s) and the quoted discharge time (16s).

So if you attempted to distribute pulses across multiple units to achieve continuous power, you'd need (ignoring the complexities of synchronising and switching between them) 10 of these batteries.

In that context, the interesting question is, how would this solution compare with the lifetime of the same 10 cells operated in parallel, each discharged at a 3C rate and thus subjected to much less abuse? And the article doesn't ask that question.

I don't know, but strongly suspect you can get higher capacity from 10 parallel cells discharged at 3C - provided you pay attention to cell balancing during both charge and discharge.

Still, does this have any merit in applications needing pulse power? Only if it offers benefits over a battery continually discharged at 3C to recharge a capacitor capable of sustaining the pulses.
