Sometimes good things come in small packages. And sometimes those things are the most powerful batteries on the planet. Researchers at the University of Illinois at Urbana-Champaign have developed a tiny lithium-ion microbattery that leaves larger supercapacitors in the dust.
Scientists at Rice University have managed to design a lithium-ion battery that can be painted on virtually any surface.
Researchers from Northwestern University are working on developing a super-battery that can keep a cellphone charged for a week and be recharged in just 15 minutes.
