Researchers at the University of Leeds in the UK have invented some new batteries, that are smaller, cheaper, lighter and safer than current batteries. It’s also possible they will even last longer than what you presently have in your devices.
These lighter lithium jelly batteries might someday replace polymer gel batteries. They will contain about 70% of a liquid electrolyte that can be molded in all sorts of funky shapes. This could mean the advent of non-rectangular phones and tablets. While the thought seems interesting, it’s going to be a design challenge to get a device like that right.
These jelly batteries are supposed to cost as little as 10 to 20% of polymer batteries, easy to produce and resistant to damage. But they’re still not edible.
