Transparent Lithium ion battery

Transparent Lithium ion battery

For the last ten years the engineers developed a set of the technologies, allowing making transparent displays and other components of digital devices. The creation of transparent and flexible power supplies is more complex challenge as in the battery it is extremely difficult to make electrodes rather thin in order that they were invisible, and thus to make them extensible. The group of physicists from university Illinois created a lithium ion battery, capable to stretch three times and thus to develop electricity, which will allow to create completely transparent and flexible electronics in the near future. They turned lithium – the ion accumulator into a mosaic from the microscopic micro capsules connected in a whole by means of flexible conductors, braided in “snake”. As researchers explain, such design has at once several advantages. First, the small sizes of capsules and conductors connecting them allow making the battery completely transparent. Besides, flexible conductors between separate micro cells allow such accumulator to stretch without risk of a rupture of conductors or contact platforms. Scientists made some prototypes of such accumulators, using copper and aluminum for production of contact micro platforms, polymeric gel as electrolyte and copper microwires — for “snake” weaving. The group of scientists charged batteries, connected to them a light-emitting diode and tracked how strongly it is possible to stretch the accumulator. The scientists think that their invention quietly transfers any deformations and is capable to stretch three times without loss of properties. As the scientists believe, this power supply, together with wireless lithium ion battery developed by them, can become a basis for completely transparent and flexible mobile phones and tablets in the future.
