Data selection is the most important factor in the battery planning process. The characteristics of different data functions are different, and the battery functions developed are different. Positive and negative data matching cycle function is good, long battery cycle life. Generally speaking, in the process of planning and assembly, the capacity of the negative electrode is generally required to be greater than that of the positive electrode. Otherwise, the negative electrode will precipitate the lithium during charging and form lithium dendrites, which can affect safety. The ratio of negative electrode to positive electrode is too large, the positive electrode may appear too much delirium, forming structural collapse.
