AAAAAAAAA-size Li-Ion Cells

Posted by timothy on from the batteries-make-the-world-go-round dept.

Jasin Natael writes "Thought Li-Ion batteries were all the same? Think again. Several universities, under a grant from the US Office of Naval Research, are miniaturizing the anodes and cathodes of Li-Ion batteries to nanoscale, hoping to make more efficient, smaller cells that last longer."

  1. Energy Density Does Not Scale. by WittyName · · Score: 5, Informative

    This is a constant, dependant on the substance used in the battery. They may get 10 percent more watt hours in this battery. Peak current should be better, due to larger surface area of the anode/cathode. Lithium Polymer batteries have a higher energy density BTW.
