Transparent battery charges itself using the sun

Renewable energy and batteries go hand in hand. Renewable energies need batteries to store the energy produced, so as to use it continuously, not only when the sun shines or the wind blows. On the other hand, the batteries in our devices need charging, and renewable energy are the best way to achieve this goal.



But what if battery will be able to generate the energy needed to charge? This is exactly what was created by researchers at the University of Kogakuin in Japan. The group developed a thin, semi-transparent lithium-ion battery that recharges when exposed to direct sunlight.

Instead of having to connect a separate solar panel, translucent battery works as a battery and photovoltaic cell. The researchers hope that in the near future, this technology will evolve and be used for large, transparent Windows smart buildings that can generate and save energy.

This group four years ago was transparent lithium-ion battery which is charged by a connected solar panel. In order to create a new battery two-in-one, the team made a few minor tweaks with the materials, using lithium iron phosphate for the positive electrode and lithium titanate and lithium-hexaphosphate for negative electrode.

When the battery is exposed to sunlight it becomes stained, missing about 30 percent of the light that allows you to feel the energy. Battery is semitransparent because it is very thin — a thickness of from 80 nanometers to 90. Once the battery is low, the shading disappears and the light transmission rises to 60 percent.

The battery has a capacity of 3.6 V and the team has successfully completed testing at 20 cycles of charge/discharge.

The smart buildings technology could also one day replace the screens on smartphones and other devices, allowing them to charge themselves when you use outdoor under sun light. published
