Are there charge/discharge curves? In general, it seems absurd how little energy we store, going from 3.9V up to 4.2V. And it's bad for cycle count. Yet we keep doing it. Kind of weird setup in this paper- it's not really comparing to LiFePO4 is it? Lifepo4 top out at like 3.6V no? Lipolymer goes to 4.2V but have markedly less cycle count. The promise of LiNiMnCo (LiMNC) with more capacity though is compelling, for sure.
