In China, we invented the transparent battery for gadgets

It is easy to imagine the freedom of designers and engineers would enable to create a transparent and translucent gadgets. However, if the electronics is still possible to do such, it spoils the whole picture of the battery: its shell can be made of transparent material, but the internal electrodes and the parts will inevitably be visible. Using existing technology, this restriction does not circumvent in any way - unless you use the idea of ​​the student Yuan Yang (Yuan Yang), who proposed to his professor and Tsuyu (Yi Cui) make all "visible" parts battery is just too small, so that the eye can distinguish between them.

Indeed, we are unable to see objects smaller than 50-100 microns and Tsuyu and Jan managed to get an ordered network of electrodes with a diameter of 35 microns. It is immersed in a transparent gel electrolyte and covered with the transparent Lenkoy polydimethylsiloxane (this polymer is used in particular for the production of contact lenses - although much of it can be known as a popular sorbent "Enterosgel"). The resulting battery is thin, flexible and transparent: in the first versions of the prototype successfully missed 62% of the light.

He, however, has another drawback: the energy intensity of the prototype is approximately twice lower than that of standard lithium-ion battery of the same size, and is comparable to low-power nickel-cadmium batteries. The authors, however, do not lose heart: their prototype makes it easy to increase it in size, expanding the network of electrodes and increasing capacity without compromising its main properties - transparency. Production technology is easily scalable.
