A few days ago, researchers from the Massachusetts Institute of Technology and Tsinghua University in China jointly developed a "egg yolk and eggshell" battery
.
At present, the lithium battery used by people will lose lithium when the expansion and contraction occur every time the electrode is charged, which will shorten the life
of the battery.
The electrodes of the new battery are created by nanoparticles, and its positive electrode consists of
titanium dioxide "eggshell" and aluminum "egg yolk".
When the "yolk" is separated from the "eggshell", the voids allow it to expand and contract so that the shell is not affected
.
In addition to becoming more durable, the capacity of this new battery has also increased significantly, 3 times
the capacity of lithium batteries for mobile devices today.
In other words, new nanoparticle lithium batteries can last for days in smartphones, laptops, and tablets
.
In addition, due to the significant slowdown of the battery charging process, the charging time of this battery is also greatly shortened, only 6 minutes
.
At present, the battery is still in the experimental stage, but researchers believe that this cheap and simple battery will be able to be mass-produced
in the future.
MIT professor JuLi said that although the method of making this battery was a serendipitous discovery, it could eventually become a strong competitor to existing lithium batteries
