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."

    what really really pisses me off is people on slashdot saying "do you have *ANY* evidence for this".. what is this? Amateur geek lawyer club?

    I suppose you know a lot about electronics design to be making such a judgment. Get out of dream world and hop on over to the real world.

    a poster with a name like 'space-mongoose' can tell his ass from his elbow, much less design battery chemistry.

    Why should we waste our important time reading inept postings like this? Mod this entire thread down!!!
