An industry commentator has suggested that super-capacitors will be increasingly important in the future.
Writing for the Penny Sleuth blog on Fleet Street Invest, Tom Bulford claimed that the power consumption of mobile devices is growing at three times the rate of the batteries that are built to keep them going.
He pointed out that one solution to this situation is the use of super-capacitors, which store more energy than a capacitor, but deliver it more slowly than a conventional battery.
Mr Bulford explained: "A super-capacitor can act as a buffer, storing a low charge from the mobile's conventional battery and then delivering it when required."
In his opinion, super-capacitors could be useful for cameras on mobile phones, since they do not usually have a bulb on them to create a flash.
The huge burst of energy it takes to create this light can run down the battery, but this situation could be eased using this distinct form of battery technology.
Electric Cars being developed at Carnegie Mellon University will also use super-capacitors.
