The invention relates to a sodium ion battery, which comprises a positive electrode MATERIAL or a positive electrode material obtained by the preparation method of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC. It will have the following beneficial effects: First, α = (DV90-DV10)/dv50, in this formula, dv50 is usually considered to be the standard particle size, (DV90-DV10)/dv50 ratio near 1, indicating that dv10 is very small, close to zero, and dv90 is close to dv50.
This indicates that the particle size of the spheroids in the dv90 range is close to the standard particle size, and a small number of spheroids have very small particle size. It can be seen that the particle size distribution of the positive electrode MATERIAL of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC technology is concentrated and uniform, and contains fewer small particle size particles. β is the average ratio of the long axis length to the short axis length of the spheroid in the size distribution range of dv50.
When β is close to 1, it means that the spheroids in the size distribution range of dv50 are close to spheroids, it can be seen that the positive electrode material is basically a sphere with regular shape, so, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC electrode technology has uniform size and regular shape, compared with the traditional technology, which has irregular shape and wide particle size distribution.
