Researchers Create Lithium-Ion Battery that Can Stretch to 300% its Original Size

Researchers at Northwestern
and the University of Illinois at Urbana-Champaign have created a
stretchable, flexible lithium-ion battery that can be recharged
wirelessly. This is big news for wearable computing, roll-up displays,
and implantable devices - all of which have been desperately awaiting a
flexible, stretchy power source.
Historically, batteries, with
electrodes made out of large slabs of graphite and metal, are about as
inflexible as it gets. Bend a laptop battery and, if you're strong
enough, it will break (and possibly explode, so please don't try it at
home). There's also a toxic, liquid electrolyte in most batteries, which
generally means you want a hard, rugged chassis to stop any leakages.
