The Next Notebook Battery? Lithium Polymer
Lewis Clarke writes "Sony is changing its course to use an old technology for its new battery manufacturing. ZDNet is reporting on comments from Sony Electronics President Stan Glasgow, 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." From the article: "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 that's now a plus."
An extraction isn't even in the same ballpark as a root canal in terms of discomfort at the time.
Of course, there's a perceived benefit in keeping the tooth.
Reality has a conservative bias: it conserves mass, energy, momentum...
