How Scientists have created highly efficient battery after recycling used medical face masks?

To get rid of the problem of the accumulating number of used medical face masks in the trash, scientists have found a way out. They developed a high-efficiency battery from recycling, not very expensive but the cheapest one.

How they did it?

First scientists began passing ultrasound so that used medical face masks could be disinfected. Then they immersed disinfected medical face mask into the ink made up of graphene and heated the same with temperature up to 140 degrees Celsius. The purpose of doing this was to get conductive granules that paved the way for the creation of working electrodes. From there, the insulating layer has been separated from used medical face masks. The overall composition is saturated with electrolytes and shielded with a protective shell develop from other types of medical trash – blister packages for medicines.

Scientific results

While describing the initial tests, researchers said that the battery made from used medical face masks had achieved the 99.7 Wh/Kg energy density that was not sufficient and thus had lagged behind while comparing the density of lithium-ion battery range from 100 to 265 Wh/Kg. In order to achieve that energy density level of the lithium-ion battery, they added perovskite nanoparticles of calcium oxide and cobalt to the electrodes. Following this, scientists achieved their desired outcome, and in that way, the energy density level reaches 208 Wh/Kg. 

Newly created battery capable of retaining 82 % percent and could last for one and half thousand charging cycles, according to the claim made by scientific researchers.

Video

I could not find any video regarding the aforementioned scientific experiment but will share it when I got it. Meantime, if you find it, then don't forget to share.

So keep visiting for the latest updates. Thanks

Man thinking with question marks in background If we could recall in the past, it was April 24th, 2005  was the date in which first YouTube video was published but what was the topic? Amazingly the first YouTube video was made in the zoo premises and interestingly it was about elephants . Almost twenty years ago, the title of that video was Me at the zoo , YouTuber Jawed was talking about long trunks of elephants for his viewers standing in front of elephants in the San Diego zoo.  It was not very long video but contains length of only 0.19 seconds. Till today, this short video got a record of 355,821,917 views.  If intended to watch again, could be found easily by searching in Google, YouTube and other search engines.

pixel art emoji smiley face It was a pleasant day at Paris, when Julius was strolling around  Arc de Triomphe  with her fiancée Darcy, suddenly received a Google news alert in his smart phone, so he swiped the screen of mobile phone, found an interesting article to read and headline was  This Pixel Window can turn any object into pixel art Pixel Window The creator from Japan has made an unusual innovation that can turn any object into a pixel art. It’s a prism that he named  Pixel Window . If you keep this prism before any object, let’s say Taj Mahal, it will show it in cubes. The Artist-engineer Monoli while disclosing about Pixel Window told that prism have been created in the shape of a small glass cube. By looking it at in the picture, you can foretell its small size is of few centimeters. Whoever looks into Pixel Window, could see an eight-bit image of object. If you wish to buy it than have to wait because design of Pixel Window is in final stages and therefore...
