The recent technology that has been introduced in the world of electronics is a battery that recharges and works on solar energy. The rechargeable battery that is the first of its kind is made by Ohio State researches. The working detail and the structure of the battery are mentioned in the journal Nature Communications.
The structure depicts a built in solar cell and the battery components. A mesh of solar panel made of titanium oxide crystals on a titanium base allows sun rays to enter the battery resulting in an exchange of electrons between the cell and the electrode of the battery. The system work like plants, the oxygen and light is captured and is then utilized to generate electricity for charging the battery. The crystals of the mesh work as capturers of energy while titanium base serves as a passage for air.
The whole internal system works on three electrodes and an iodide additive placed between the electrodes acts as an electrolyte. The crystals making up the first terminal, the second one being the porous carbon sheet under the titanium gauze and a lithium plate under carbon sheet serves as a third electrode. Oxygen that is absorbed from the atmosphere forms lithium peroxide reactant with the lithium plate however the electrons generated through solar cell breaks the compound into lithium atoms and oxygen. The latter acts as a by product and is released out.
The battery as the researchers’ claim is a combo of two technologies. Previously the combination provided less efficiency with only 80 percent of electrons reaching the target. However this time, approximately all of the electrons destined to charge the battery and produced by the solar cell are able to reach the targeted goal.
Yiying Wu, a professor of chemistry and biochemistry at Ohio State University told that the solar battery they have developed is the integration of two devices – a solar panel and a battery. The panel captures the energy while the battery stores it. He further laid his emphasis on the device cost effectiveness. He called his creation as a breathing battery telling that the battery takes in air at the time of discharge and exhales out when charging.
Wu also mentioned his previous experience with a doctoral student Xiaodi Ren of winning $100,000 prize from the U.S. Department of Energy. The reward was given on their joint invention; an invention of a battery powered by air. The machine’s working involved air expulsion as a result of reaction between potassium and oxygen.
