M.I.T. researchers are working on using capacitors instead of the current electrolyte solutions to provide super-fast charging in portable devices.
Capacitors contain energy as an electric field of charged particles created by two metal electrodes and charge faster and last longer than normal batteries.
How would you like your iPods and laptops to be up to power faster than you can find and plug in the charger? Better yet, these new super-batteries may never need to be replaced, possibly by not degrading the way current batteries do. The future looks awesome.
