  • Publication number: 20230147558
    Abstract: A negative electrode material includes a dopant containing a first dopant and a second dopant, the first dopant contains a boron element, and the second dopant contains at least one selected from a group consisting of a nitrogen element, an oxygen element, a fluorine element, a phosphorus element, and a sulfur element. Two or more types of dopants are added in the particle producing process, so that the negative electrode material prepared has excellent high and low temperature cycle performance and rate performance. Furthermore, a carbonization coating process is omitted which is compatible with the preparation process of the conventional graphite negative electrode, thus the preparation process is simpler, the equipment required is less, and the cost is lower. A preparation method thereof is provided as well.
