The microscope’s custom-made tip touches the electrode to charge and test the battery.  (This  custom tip is so tiny, being only two nanometers wide, that it cannot even be seen by an ordinary light microscope.) </div><br> <div> The team has, to date, been able to develop batteries so minuscule that more than 40 can be lined up across the width of a hair.   </div><br> <div> Today, these batteries are in the laboratory producing about a millionth of a miliAmp, but in the future, they could be found as a power source for a computer or a medical device.   </div><br> <div> References: U.S. Patent 6,586,133 and Dewan, C. & Teeters, D., “Vanadia xerogel nanocathodes used in lithium microbatteries,” <i>Journal of Power Sources,</i> p.119-121, 310-315, 2002 </div><br> <br> <div align="left"></div> <div> BD </div><br> </td> </tr> </table> </body>
