Printable, flexible, rechargeable battery developed at UC San Diego

Researchers at the University of California San Diego have developed a new type of printable, flexible, stretchable, wearable, rechargeable battery.

The material is made from isoprene, a hyper-elastic polymer found in rubber, and polystyrene, along with a zinc silver oxide ink mixed with bismuth oxide. This allows the batteries to stretch to twice their size without damage and ensures it’s rechargeable.

The technology is still in its early stages but looks promising – the prototype only has about a fifth of the capacity of a hearing aid battery but is a tenth as thick, is cheaper, and uses readily available materials.

The researchers are interested in matching their technology with solar power or fuel cells so that it can power more types of devices.
