If we're talking about day-to-day battery issues in regards to devices like phones and laptops, the battle can be won on number of fronts, for example: 1) Batteries get enough capacity so you only need to charge them once a month. 2) Batteries can be fully charged in a short period of time, say one minute, we wouldn't bothered very much to have to plug them in once a day. 3) Carrying around a device at home or work for few hours a day will keep the device charged for a whole day (via the "superlens"). Any of the aforementioned solutions and perhaps few others would solve the issues we have with batteries in our handheld devices today. For cars, trains and other battery uses, that's another thing.
