This is not really a new chemistry, but reformulated design (small particles
etc) to try to
improve the very poor cycle life these batteries have demonstrated
historically. Z-power claims
~300cycles, which is still a fair bit less than that claimed by Li-ion. But
practical cycle
performance in batteries usually falls far short of all these claims,
especially in battery packs
in long strings versus single cells. You can improve cycle life by shallow
cycling or charging to
lower voltage (and hence lower capacity) with Li-ion. If the practical energy
density really is
40% more, people may likely still pay a premium and accept the lower cycle
life.
