Simple Chemical Trick To Boost Battery Efficiency

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."

On behalf of all australians:

Could you please prop up the value of your US dollars - it's rather annoying to get pesos in return for our raw material being exported.

Then again, we like being able to buy your products - oh wait, you don't make anything. Never mind, then.
