Innovation for cell phone batteries is lagging far behind the one for smartphones but researchers at the University of Illinois at Urbana-Champaign are working on new lithium ion batteries that would be more powerful than anything we have seen so far. These new powerful batteries would be able to charge smartphones in a very short amount of time.
The Upcoming Innovation
What’s different? Right now it is difficult to have both power and energy, which is what smartphones require. The new batteries combine both and are much smaller than the ones that are currently used, giving them the capacity to charge devices way faster.
According to the university’s press release, “the new microbatteries offer both power and energy, and by tweaking the structure a bit, the researchers can tune them over a wide range on the power-versus-energy scale”.
The researchers were led by William King, professor of mechanical science and engineering. Professor King explained “If you want high energy you can’t get high power; if you want high power it’s very difficult to get high energy. But for very interesting applications, especially modern applications, you really need both. That’s what our batteries are starting to do. We’re really pushing into an area in the energy storage design space that is not currently available with technologies today.”
With these new powerful batteries, one would not have to worry about struggling to keep a phone charged trough an entire day.
The Alternative Solution
An alternative solution to a dead cell phone is to use public phone charging. Whether for an emergency situation or because you can’t wait to revive your phone but you don’t have your charger with you, phone charging kiosks placed in public places can solve your problem.
