A Japanese company is giving us hope though. Eamex says that it has developed new technology that will extend the life of Lithium Ion batteries. Just how much longer will they last? If reports are to be believed, these new batteries can be charged and discharged for more than 10,000 times. Even better, they will last for 20 years. That’s far longer than most gadgets will last the average person!

Just to give us an idea of how the technology works, Eamex says that they have solved the main problem of short battery life: the weakening of the bond between the particles of an essential part of batteries: the tin-coated resin. If this bond is made to be stronger for longer, then batteries will last more than they do today. Again, Eamex claims that it has solved this problem. The forecast is that by the end of this year, they will be able to launch the new battery. Now I wonder how much this will cost?

This is interesting… and I think this is most useful to people who have less space in their laptop bags for an additional bulky battery charger. You’re in a conference and your portable audio recorder is loosing its power juice. No problem, just use the USB rechargeable AA battery. Grab a second pair so that you can charge the flat pair over your laptop’s USB port.

At 550 mAh, these USB rechargeable batteries are built for smaller gadgets. You probably can’t use it on your digicams.. noooo… just the smaller ones.
