A tenfold increase in capacity of any battery technology would be a scientific breakthrough that would be front page news. A company that developed such a battery could patent the technology, charge 5 times as much and rake in billions. Frankly I think you're just talking out your ass. |

Or ten times longer before they leak. |

we had the answer back in the 80's just recharge your "disposable" batterys http://www.radioshackcatalogs.com/html/1989/h142.html |

I have tried some experiments with recharging alkaline AAs (not Duracells, that would be futile, but Hitachi Maxells). Even when using very slow charging at 100 mA, and a very conservative termination of 1.55 V, there was slight leakage on 1 cell out of 4. The alkaline cells that were intended for recharging would have had different geometry to handle gas generation and so on, and even those were prone to leakage, one reason they didn't last long on the market. |
