PROTECTIVE COATINGS FOR CONVERSION MATERIAL CATHODES |
| 摘要 |
Battery systems using coated conversion materials as the active material in battery cathodes are provided herein. Protective coatings may be an oxide, phosphate, or fluoride, and may be lithiated. The coating may selectively isolate the conversion material from the electrolyte. Methods for fabricating batteries and battery systems with coated conversion material are also provided herein. |
