  "textContent": "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 materials used in the positive electrode of sodium ion battery to achieve higher charge/discharge rate (i.e. capacity retention is better at high discharge rate), long life cycle and reduced reliance on the expensive and toxic cobalt, all of which are desired attributes for improving the performance of sodium ion batteries and reducing their cost.",
