$begingroup$ I guess this is only true for heterogeneous catalysis, when you need a mechanically-stable porous matrix with developed surface area. In homogeneous catalysis you want the opposite, so that your catalyst remains dissolved all the time and doesn''t precipitate, so the calcined compositions are probably the worst choice here.

The most popular anode material in commercial Li-ion batteries is still graphite. However, its low intercalation potential is close to that of lithium, which results in the dendritic growth of lithium at its surface, and the formation of a passivation film that limits the rate capability and may result in safety hazards. High-performance anodes are thus needed.
