METHOD FOR PRODUCING COATED ACTIVE MATERIAL - A simplified explanation of the abstract

• This abstract for appeared for US patent application number 18110475 Titled 'METHOD FOR PRODUCING COATED ACTIVE MATERIAL'

Simplified Explanation

This abstract describes a method for producing a coated active material. The method involves applying a layer of niobium coating onto the surface of the active material. This is done by transforming a slurry, which contains the active material and a coating solution with niobium, into droplets. These droplets are then dried in a heated gas stream to form a precursor, which is subsequently baked. It is important to note that the active material used in this process must have a sulfur impurity content of less than 0.68 wt%.

Original Abstract Submitted

In a method for producing a coated active material, a coating layer containing niobium is formed on at least a part of a surface of an active material. The method includes: transforming a slurry containing the active material and a coating solution containing niobium into droplets to obtain slurry droplets; drying the slurry droplets in a heated gas stream to obtain a precursor; and baking the precursor. The active material that is used to obtain the slurry droplets contains less than 0.68 wt% of sulfur as an impurity.
