The morphology of the porous network in porous SiC has been studied. It has been found that pore formation starts with a few pores on the surface and then the porous network grows in a V-shaped branched structure below the surface. The hydrogen etching rates of porous and nonporous SiC have been measured.
Porous positive electrode precursor, composite positive electrode material, and preparation method and application thereof
This invention provides a porous cathode precursor, a composite cathode material, its preparation method, and its application. The preparation method of the porous cathode precursor includes the following steps: co-precipitating a ternary mixed metal salt solution, a complexing agent solution containing citrate, a precipitant solution, and an oxidant solution into a reaction substrate to obtain a half-step precursor material; and pre-sintering the half-step precursor material to obtain the porous cathode precursor. The cathode precursor prepared by the method provided by this invention has a hollow porous morphology, which is beneficial for improving the cycle performance and rate performance of the ternary cathode material.
