Nope. Both NiMH and lead acid batteries are less efficient in this regard. And supercaps have lower energy density, although they are improving quickly too.

- Hypx_ 5y agoNiMH is around 90% efficient too. Lead-acid around 85%. Also, li-ion don't do well under high discharge rates and can drop to <70%. It's not a perfect cell technology by any means.
