Abstract

The present invention discloses a method for preparing a tightly coated cobalt oxide and a use thereof, the preparation method comprising: synthesizing spherical cobalt hydroxide particles by a coprecipitation method; after drying and dehydrating them, uniformly mixing them with zirconium alkyl carboxylate/aluminum alkyl carboxylate and zirconium hydroxide/aluminum hydroxide and heating the mixture to enable the zirconium alkyl carboxylate/aluminum alkyl carboxylate and zirconium hydroxide/aluminum hydroxide to react with the cobalt hydroxide on the surface layers of the particles, so as to tightly attach them to the surfaces of the spherical cobalt hydroxide particles; and finally, performing calcination to remove organic matter so as to form spherical cobalt oxide particles with close coating layers on the surfaces. By using chemical bonds to connect the coating layers and a base material, the present invention allows these two elements to be more closely attached and not subject to pulverization and falling off, thereby greatly extending the service life of the coating layers, and improving the cycle performance of the material.
