Recently, researchers from the Massachusetts Institute of Technology and Tsinghua University in China have developed an "egg and eggshell" battery that can be recharged in 6 minutes. The electrodes of the battery are created by nanoparticles, whose positive electrode consists of titanium dioxide "egg shell" and aluminum "yolk". When the "yolk" is separated from the "egg shell", the void allows it to expand and contract so that the outer shell is not affected. However, the lithium battery used by the current battery has a lithium loss when the electrode is charged once, and the battery life is shortened when the expansion and contraction occur. In addition to becoming more durable, the capacity of this new type of battery has also increased significantly, three times the capacity of lithium batteries for mobile devices. In other words, the new nano-particle lithium battery can make smartphones, notebooks, and tablets work for several days. In addition, because the battery charging process has been greatly slowed down, the charging time of this battery is also greatly shortened, only 6 minutes. At present, this battery is still in the experimental stage, but researchers believe that this kind of battery, which is cheap and easy to manufacture, will be mass-produced in the future. “These egg yolk-egg 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 most attractive thing about this job is that the new battery is simple to make and scalable." MIT professor Ju Li said that although the battery was made by chance, it eventually became a strong competitor for lithium-ion batteries. Concerned about surprises
