Is the “charging issue” fading away anytime soon?

The impression I have, shared by many, is that batteries are lagging behind in the evolution race. I am still having problems with depleting charge and I am still looking for some power socket to recharge my, many, devices.
And yet, I acknowledge this is just an impression and that in reality batteries have progressed significantly. The fact is that our "power" needs have also increased considerably with the result that we are still experiencing the same urge to recharge we had several years ago (on the other hand, I am still running out of storage capacity, in my digital camera, in my computer, in my hard drive …. and I am still buying more capacity on a yearly bases).
Progress have been made in many areas, like more capacity per battery volume, faster recharging and also ways of recharging.
As an example, Starbucks has announced the plan to equip its 7,000+ stores with recharging mats that can let you recharge your phone (or tablet or watch…) as you drink your coffee. The recharge is using induction. They are placing recharging mats in their tables and a recharging ring connected to your device power inlet can suck the energy waves emitted by the mat and recharge the battery.
Other approaches try to shorten the time it takes to recharge the battery, like the work being done at the University of California where the aim is to shorten the time it takes to recharge to 10 minutes (or as they say the time it takes to sip a coffee).
Looking further down the lane we are starting to see the possibility of having our wearable devices being continuously recharged by the power generated by smart dresses. The fabric they are made of will transform mechanical stress resulting from walking around, light absorption and temperature gradient into electrical power to feed the batteries.

About Roberto Saracco

Roberto Saracco fell in love with technology and its implications long time ago. His background is in math and computer science. He's currently the Chair of the Symbiotic Autonomous Systems Initiative of IEEE-FDC. Until April 2017 he led the EIT Digital Italian Node and up to September 2018 he was the Head of the EIT Digital Industrial Doctoral School. Previously, up to December 2011, he was the Director of the Telecom Italia Future Centre in Venice, looking at the interplay of technology evolution, economics and society. At the turn of the century he led a World Bank-Infodev project to stimulate entrepreneurship in Latin America. He is a senior member of IEEE where he leads the Industry Advisory Board within the Future Directions Committee. He teaches a Master course on Technology Forecasting and Market impact at the University of Trento. He has published over 100 papers in journals and magazines and 14 books. He writes a daily blog,  http://sites.ieee.org/futuredirections/category/blog/, with commentary on innovation in various technology and market areas.
