Recently, researchers from MIT and Tsinghua University in China have developed an egg yolk and eggshell battery that can be recharged within 6 minutes. The electrode of the battery is created by nanoparticles. Its positive electrode consists of titanium dioxide "eggshell" and aluminum "yolk yolk". When the "yolk" is separated from the "shell," the void allows it to expand and contract so that the shell is not affected. Lithium batteries used today have lithium loss at the time of expansion and contraction when their electrodes are charged once. This will shorten the life of the battery.
In addition to becoming more durable, the capacity of this new type of battery has also grown substantially, which is three times the capacity of current mobile device lithium batteries. In other words, the new type of nanoparticle lithium battery can make smart phones, laptops, and tablet computers use for several days. In addition, due to the sharp decrease in battery charging process, the charging time of this battery is also greatly reduced, and it only takes 6 minutes.
At present, this battery is still in an experimental stage, but scientists believe that this material is cheap, simple production of batteries in the future will be able to mass production.
"These egg yolk-shell particles have shown impressive performance in laboratory-scale tests," said David Lou, associate professor of chemical and biomolecular engineering at Nanyang Technological University in Singapore and co-author of the study. "To me The place that attracted me the most in this work was the simple manufacturing process and good expandability of this new type of battery."
Ju Li, a professor at MIT, said that although the method of making this battery was an accidental discovery, it eventually became a strong competitor to current lithium-ion batteries.
