Simple Chemical Trick To Boost Battery Efficiency

Posted by samzenpus on from the power-up dept.

space_mongoose writes "Hitachi thinks that a simple chemical additive could significantly improve battery life. Alkaline batteries have a positive electrode of manganese oxide and a negative electrode of finely powdered zinc, but zinc oxide forms around these grains of zinc. Hitachi's solution is to replace the zinc with a fine powder of zinc-aluminum alloy, displacing the zinc within the zinc oxide layer making it a much better conductor."

    Would that be their current current requirements?

    Currently, yes. They're all amped up, you'll be unable to resist them when they come out. Shocking charges, I know, but few have the capacity to induce or impede such a flow of power, watt?
