US Patent Issued to The Regents of the University of California on Nov. 11 for "Doping strategy for layered oxide electrode materials used in sodium-ion batteries" (California Inventor)

ALEXANDRIA, Va., Nov. 11 -- United States Patent no. 12,469,847, issued on Nov. 11, was assigned to The Regents of the University of California (Oakland, Calif.).

"Doping strategy for layered oxide electrode materials used in sodium-ion batteries" was invented by Huolin Xin (Irvine, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "The present invention features a new way of doping layered cathode materials in sodium-ion batteries. Using a "high entropy" doping strategy, more than four impurity elements can be introduced to the host materials. The present invention applies this high entropy doping strategy to a sodium cathode material. This new high entropy doping strategy allows the layered oxide materi...
