American academician develops 10-minute lithium battery fast charging technology, expected to be commercially available within 2 years

To solve the anxiety about the battery life of electric vehicles, battery fast charging technology may be more promising than increasing battery capacity. Wang Chaoyang, an academician of the National Academy of Inventors, recently announced the latest research results. High-density lithium batteries can also be charged in 10 minutes and have a long lifespan. Up to 2000 times.

Academician Wang Chaoyang is an academician of the National Academy of Inventors, a chair professor at Pennsylvania State University, the dean of the Institute of Battery and Energy Storage Technology, an executive member of the Battery Branch of the Electrochemical Society, and an expert on the Beijing Science and Technology Winter Olympics New Energy Vehicle Expert Group. Science and technology committee member of the World New Energy Vehicle Conference.

Recently, his team published the paper "Fast Charging of High Energy Density Li-ion Batteries" in the journal Nature, reporting a breakthrough in eXtreme Fast Charging (XFC) technology.

It is understood that compared with the current fast charging of cars, which still takes 45-60 minutes, the XFC fast charging technology developed by the team of academician Wang Chaoyang has achieved the 10-minute extremely fast charging of high energy density lithium-ion batteries (265 Wh/kg) for the first time, and the cycle The life span is up to more than 2000 times.

This is equivalent to the car achieving a battery life of 500,000 miles, and each charge is at a fast charging speed.

In addition, the research also revealed for the first time that high-specific energy power batteries require only air cooling for extremely fast charging, thus greatly improving the integration, reliability, and safety of the battery system.

More importantly, compared with the previous situation where many fast charging technologies could not be mass-produced in a short period of time, all experiments on this fast charging technology used existing industrial-grade mass-produced battery materials and are expected to be used on a large scale within 2 years. .
