Nice, hadn't heard that one. Still consistent with the quote I cited though.
Submission + - Simple chemical trick to boost battery efficiency
space_mongoose writes: Hitachi reckons 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-aluminium alloy, displaces the zinc within the zinc oxide layer making it a much better conductor.
