Researchers at Ohio State University reported, according to them, the world's first rechargeable solar battery. Normal solar cell converts light energy into electricity, but in the dark or inclement weather such power sources are not suitable for use. For this reason, the excess energy generated by solar battery is necessary to store in the battery, resulting in significantly increases the cost of installation. Furthermore, efficiency is lost because some power is wasted during the transfer from the source to the battery.
Proposed by researchers, a group headed by a Yuying Y (Yiying Wu), one solar cell consists of a grid formed by thin threads of titanium coated with titanium dioxide. Mesh cells allow atmospheric oxygen to freely enter into the device, where it is involved in the energy transfer.
Under the influence of light the battery is charging: titanium dioxide is the source of free electrons that trigger the decomposition reaction of lithium peroxide, lithium ions and oxygen. . Upon discharge, the process is reversed: the battery consumes oxygen to form lithium peroxide. Related Products :
