Scientists battery that recharges via light
Indian scientists have built a battery that can recharge themselves using light. There, the battery, although it has a small storage capacity, thirty seconds before. For the time being it is a prototype.
The researchers have a paper published their findings in the journal The Journal of Physical Chemistry, as reports PhysOrg. The battery proposed by them has a titanium anode which is photosensitive. The cathode is constructed of hexacyanoferrate and the whole is surrounded by a liquid. Experiments show that the light-sensitive anode ensures that the battery can charge itself with light. This looks like a solar cell, but the difference is that conventional solar cell energy generation, but it can not do without to save more.
According to the authors, the battery has a capacity of 77.8 mAh per gram when light is shone on. This is not necessarily sunlight necessary: artificial light also ensures that energy is stored in the battery. Tests have shown that in normal room light charging takes only 30 seconds. It should be noted that the built battery is still too small to store much energy. However, it proved to be able to send out to an LED, and more than 100 charging cycles to be able to come along.
It is still a prototype, which is not used immediately in new products. Because it is an early version is too early to say if and when such batteries are commercially available yet.
