Zinc air batterys been around for years.there activated buy AIR so i cant see them being much use in hermeticaly seald flashlights:shakehead
I'm curious as to energy density and power density of this zinc-air cell. Is there any data available?
What about with a light like the firefly(air hole has to be opened to make it work?")the highest!!!!!! more than the double of the best li-ion, but of course... they aren't rechargeable
the shelf life is very high but only until you remove the sealing tape, after that the battery will discharge in few months also if you don't use it
they aren't high current batts... they are good for be discharged in some days
