Everyone is well aware of the common types of batteries we have floating around in today's electronics: Li-Ion, NiMH, Ni-Cad, Li-Poly, Alkaline...just to name a few. However, there is another contender that we don't see around today's electronics too often, called "NaS" (Sodium Sulfur).
NaS batteries have been around for a while now, especially in Japan. Only recently, however, has Korean steel-making company POSCO succeeded in developing an NaS battery for storing large amounts of energy. Now, we're not talking about as much energy needed to power hybrid cars (according to the chart below), but we are still talking about a fairly lengthy period of time.
While NaS batteries aren't new, POSCO claims that it's NaS batteries have a lifespan of more than 15 years. If this sort of technology were to expand, and if both NaS batteries and POSCO live up to the expectations this news may bring about, then perhaps the idea of very-long-lasting-batteries in handheld electronic devices, or any electronic really, will be achieved sooner rather than later.
