[交流] 一种新的高能正极材料能够提高锂离子电池安全和寿命

A new high-energy cathode material that can greatly increase the safety and extend the life-span of future lithium batteries has been developed through the close international collaboration of researchers led by the U.S. Department of Energy's Argonne National Laboratory and Hanyang University in South Korea.
      The material has also demonstrated a very high-power capability, said Yank-Kook Sun, co-principle investigator and a professor in the Department of Chemical Engineering at Hanyang University. "We are able to charge the material to 4.3 and 4.4 volts and attain a very high capacity of more than 210 milliampere hours per gram, with good power capability," he said. "Conventional cathodes have a capacity of 140 to160 mAh/g."

      The research is described in the paper "High-energy cathode materials for long-life and safe lithium batteries," and is available on the Nature Materials website.
