New Batteries at Long Last
Traditional batteries: will we finally get a new design?Battery science has traditionally been the slowpoke of the technological industry. Look at a few of its competitors – in the last fifty years, screens have gone from black-and-white to color; from grainy cathode ray tube screens to high-definition plasma. Computers that used to be housed in gigantic warehouses, using thousands of vacuum tubes, are now overpowered by tiny boxes that sit on every college students’ desk. Processors, found in most modern devices, are built on an atomic scale.
Yet the batteries we use today are still based upon the same technology that was developed by Alessandro Volta over two hundred years ago. They are large, lose electrical charge with time, can leak dangerous acids, and even sometimes explode with misuse. But now, there comes new technology to finally replace the old – the nanobattery.
There are a few projects working with nanobattery technology, and one such endeavor comes from MIT’s Laboratory for Electromagnetic and Electronic Systems (LEES), which is improving on the design of ultracapacitors. TerraDaily writes:
Unfortunately, most nanobatteries are still too expensive or impractical to be put to everyday use. Initially the technology will probably be used mostly in medical devices, military applications, and emergencies. But as is true with most technology, increases in production will likely result in decreases in cost. Perhaps one day soon the general public will enjoy laptop batteries which can hold a charge long enough to actually allow one to finish wri

Yeah… The nano technology are really becoming our way of life. Day by day. I wonder who found the nano technology.
