KDDI has recently shown off a new fuel cell battery that can be refilled with methanol, where it will run for up to 320 hours before requiring another refill. This prototype fuel cell is a type of hybrid device which will be coupled to a lithium ion battery that offers enough juice for surges in use. Unfortunately for the masses, KDDI has no plans to see the technology arrive in the market ASAP – instead, it will take at least a few years to do so. Perhaps in our childrens’ time, they can have handsets that last for weeks on end before requiring a recharge. As for now, we’ll just have to learn to co-exist with numerous chargers whenever we travel.
