Lewis Clarke writes: Looks like after the laptop battery fire fiasco, Sony would be changing its course to use an old technology for its future battery manufacturing. ZDNet reported on Sony Electronics President Stan Glasgow meeting with reporters, where he said that Notebook makers will "likely" soon choose to incorporate lithium polymer batteries (A battery technology that emerged nine years ago) over the current commonly used type, lithium ion batteries. Lithium polymer batteries use lithium as an active ingredient. Lithium is a volatile material, but the lithium in these batteries isn't packed into cells as it is in lithium ion batteries. Instead, it is contained in a polymer gel. These gel batteries can't provide the same sort of energy density as lithium ion batteries but its safe from internal short circuit that set off a chain reaction and start a fire.
