American academicians develop 10 minute lithium battery fast charging technology, which is expected to be commercially available within 2 years

    Academician Wang Chaoyang is an academician of the National Inventors Academy of Sciences, a chair professor of Pennsylvania State University, the president of the Battery and Energy Storage Technology Research Institute, an executive member of the Battery Branch of the Electrochemical Society, an expert of the Beijing Science and Technology Winter Olympics New Energy Automobile Expert Group, and a member of the World New Energy Automobile Congress.

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

    It is understood that compared with the current car fast charging, it still takes 45-60 minutes. The XFC fast charging technology developed by Academician Wang Chaoyang‘s team has realized the 10 minute extreme charging of high energy density lithium ion batteries (265 Wh/kg) for the first time, and the cycle life has reached more than 2000 times.

    This is equivalent to that the car has achieved the endurance of 500000 journeys, and each charging is fast.

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

    More importantly, compared with many previous rapid charging technologies that cannot be mass produced in a short time, all experiments of this rapid charging technology use the existing industrial grade mass produced battery materials, which is expected to be used in a large scale within two years.
