      have a look at this:

      http://www.eetimes.com/news/latest/showArticle.jhtml?articleID=159907938



      "...Toshiba's prototype battery has a capacity of 600mAh and measures.8mm
      thick, 62mm high and 35mm deep. It was demonstrated in hard disc music
      player for about 10 minutes by charging 5 milliwatts in 5 seconds.
      According to Takami, the battery shows less than 1 percent deterioration in
      capacity after 1,000 cycles of discharging and recharging...."


      by the way, anybody knows why there are not recharchable Lithium ion battery
      for sale with sizes as AA like Ni-Mh?

        The hard part of Lithium Ion is the processor controlled circuitry
        required. If you take apart most lithium ion batterys you will see
        the cells are like AA but there is a circuit in there that precisely
        controlls the charge rate.

        Because protective circutry is required in either the battery pack itself, or the device that charges it. If overheated, Li Ion batteries can produce

          Because protective circutry is required in either the battery pack

          batteries can produce explosive gasses and present a risk of fire.

          TBH, LiIon batteries do come in cell sizes identical to AA, but they
          produce 3.7vdc, so really can't be used in legacy applications without
          a lot of modification.
