Japanese invent the solar cell without a separate solar panel
According to foreign media reports, a group of Japanese researchers recently succeeded transparent lithium-ion battery was modified so that when exposed to the sun can charge itself, without the need connected with a separate solar panels.
This transparent battery was researched and developmented by the Japan Institute of Technology University professor Mitsunobu Sato and his team in 2013. According to reports, the cell anode electrolyte used mainly made of lithium iron phosphate, a cathode and electrolyte materials used include lithium titanate and lithium hexafluorophosphate.
Although these materials have been widely used in lithium-ion rechargeable batteries, but the thickness of these electrodes is only 80-90 nanometers thin to allow light to pass through, so that the battery exhibits almost completely transparent effect. And now, after changing the chemical composition of the battery cathode, the researchers discovered a new method that allows the battery to the sun or other bright light on their own charge.
