Scientists Say They’ve Created an Injection That Makes Aging Batteries Charge Like They’re Young Again

The researchers in China have developed a technique to give the lithium -ion battery cells a second snapshot in life. It was delivered as an injection, it greatly extends the age of the cells and makes them perform like their youngsters again, according to the team’s report in a Ticket It was published in the prestigious magazine nature.

“If we are able to give an injection to a sick person to help him recover,” the co -author Yue Gao, a chemical at the University of Fodan in Shanghai, He said American scientific“Why can’t we get a magic dose for drained batteries as well?”

This technique can be a penetration Reducing lithium battery wasteOne of the main defects in the promise of electric cars with a more green alternative to gas gases, which will only become more challenging with the high EV dependence. It is difficult to recycle the huge batteries of vehicles, and if not properly disposed of, the leakage of toxic chemicals that leak into the ground. Although the recycling will remain of the utmost importance, the very specialized facilities needed to treat the batteries consumed are still under the building.

The Li -EV battery package usually lasts from eight to twelve years before it is considered “dead”, “dead” This means that it has decreased less than 80 percent of its original ability. This is a decent age, but its replacement is painful: as Siam Note, almost compensates the battery 40 percent From the cost of a new EV, which puts great economic pressure on the owners.

But what if you do not have to get thousands of dollars to replace it? From the beginning, Gao and his team wanted to find a molecule that could provide fresh lithium ions to the battery cells.

“We had no idea about the types of molecules that could do this function. Siam.

The carefully composed machine learning model was recommended by three candidates, and the most promising was the salt called a trilogy lehromethans. When it dissolves in an electrolyte solution, the researchers found that the salt lithium ions that were flowing again to the deteriorating cells of the battery.

Follow -up experiences showed that the injection of the solution in the battery cell can return it to 96 percent, which extends to approximately 12,000 charging cycles. This is a dramatic boost. To refer to it, EV batteries are designed to continue for a period ranging from 1500 to 2000 charging routes.

However, researchers are the first to admit that miracle injection is not completely ready to strike in the market.

“We have only conducted cells on cells, and we need to find a way to apply it to a full battery package.” Siam. One battery pack may have thousands of cells.
