A Chinese research team has developed a unique way to help spent lithium-ion batteries regain near the fresh capacity and performance of the factory, the Chinese Media Group (CMG) reported on Thursday.
The findings of a research team from the University of Hudan in Shanghai were published in the Academic Journal Nature on Wednesday.
Extending battery life has long been a serious problem as the battery will fail when active lithium ions are consumed. “Our research breaks this limitation by a cell-level lithium supply strategy. This involves externally adding organolithium salts to assembled cells, which are during cell formation. It degrades, releases lithium ions, and expels organic ligands as gases. Rapid Process maintains cell integrity without the need for degradation,” the researcher posted on the Nature website. I mentioned it in the summary.
This innovative approach can significantly improve the performance of lithium-ion batteries and reduce waste. This is essential for electric vehicles (EVs), smartphones, and large-scale energy storage infrastructures.
The team has leveraged artificial intelligence and organic electrochemistry to develop lithium carrier molecules that can be injected into decomposed batteries to replenish lost lithium ions, and the batteries are almost factory fresh “healthy” It effectively provides “precision processing” that helps you regain your status. , members of the research team were quoted as saying from the CMG report.
Researchers expect the technology will be able to extend the lifespan of lithium-ion batteries from the current range of 500-2,000 cycles to 12,000 to 60,000 cycles, according to a report on the Fudan University website’s website.
This is an internationally “unparalleled” result of Chinese scientists, Gao said, and is expected to pave the way for high-performance, cost-effective lithium batteries, including EVs and appliances. , large scale energy storage.
The technology has been tested on a variety of batteries, and the team is working with leading international battery companies to accelerate the adoption of technology in real life, Gao said.
On Thursday afternoon, many of China’s lithium battery-related stocks rose sharply, with some rising 20% and falling under daily restrictions.
Previously, researchers from the Chinese Academy of Sciences’ Qingdao Institute for Biomass Energy and Bioprocess Technology could make breakthroughs in the field of all solid state lithium batteries, bringing the dream of smaller, longer-term electronics to reality It has sex. , CMG was reported on August 1, 2024.
This study provides technical support for the development of energy storage devices with high energy density and long service life, providing safe and durable power sources for EVs, energy storage grids, deep sea and deep sea equipment, among other things. I will. Report.
China plays an important role in lithium extraction technology and high-end lithium battery production. The latest official data showed that China’s lithium-ion battery industry achieved strong growth from January to October 2024, reaching 890 gigawatt hours, an increase of 16% from the previous year.
