U.S. Scientist Develops Breathing Battery: Conversion Rate Nearly 100%

Although traditional solar panels have great uses, they can absorb solar energy during the day and then release the electrical energy at night to supply some electrical equipment. Usually, the efficiency is low, and some energy is lost. It is from Ohio State. The University’s chemical and biochemical researchers have developed a new type of solar power generation technology that can reduce the cost of solar power generation and improve the efficiency of power conversion. The core device is a grid of nanorods coated with titanium dioxide, with many small The hole, with a span of only about 200 microns, is the basis for the new solar power generation technology.

When the solar panel absorbs light energy, the lithium peroxide inside the panel can form lithium ions and oxygen. The lithium ions have a positive charge. Therefore, many energy from the sun's light is stored in the battery when the battery is discharged. The oxygen in the air recombines to form lithium peroxide, which then forms a circulatory system that enables repeated charging and discharging. To some extent, this new type of solar cell is like a breathable charging and discharging device. When it comes from discharge, it starts to consume oxygen in the air. If it is charged, the battery is equivalent to releasing oxygen, and it will “breathe. The word "batteries" describes this device very closely.

Researchers at the Ohio State University are currently testing this new type of solar cell. In laboratory tests, the battery life is similar to the mainstream battery life on the market, and it has the potential for commercialization, if the product can be further matured. , can greatly enhance the current life of micro-batteries, and provide more power. The research was published in the journal Nature.
