Energizer - Zinc-air prismatic battery

Labels:


Energizer's new disposable Zinc-air prismatic battery which holds three times the energy of alkaline or lithium batteries.
"The battery itself has holes so that it can use oxygen from the air as one of the active materials, that's what allows us to get such a high energy density - the battery itself only needs to contain one of the active materials (zinc)," explained Jon Eager, marketing director at Energizer.
But gadgets that take the new batteries will not hit the shops until the end of the year, and will sell for up to three times the price of conventional ones.
