Can be extended to three times the size of the flexible battery

Bendable electronic devices are still listed as a future technology. A lot of research and development work is in progress to produce flexible circuits and displays, but the problem is that even if we successfully achieve these two technologies still need to consider how to power such equipment, after all, for all portable electronic devices, battery still is a solid part.

However, the University of Illinois some progress in this area. Have a research team led by Professor John Rogers, the successful development of a battery, not only is very soft and can be stretched to three times the original size, can be wireless charging.

Such flexible battery key technology is the use of energy reserve base and to be embedded in the polymer, the bending-wired connection. Is actually inside the polymer can be stretched; energy reserve base has remained in place. The wired connection is the shape of an "S" model, then circle back to their own above, as shown in the following diagram:

In such a manner for a wired connection with the stretching of the polymer, it can stretch, but does not due to the excessive pressure and fracture. When the polymer restored to its original size, the wires changed back to before the S-shaped, to wait once again opened. The polymer may be completely covered by the battery device, protecting them that do not suffer the environmental damage, for example, and contact with the liquid by an electromagnetic inductive wireless charging means.

Before this battery can be used in commercial devices, the prototype battery also requires a lot of research work, and so far, it can only be experienced about 20 charge cycles. The R & D team thinks this is a very good device solution, bendable screen for the future; this will be the perfect battery.
