I'm not sure if they 'replaced' them. The technologies sound different to me though.

DTZ ann: "NTU researchers developed the technology of embedding GQDs into Vanadium Oxide with the objective of replacing Lithium Cobalt Oxide cathodes and their use in the Li-ion battery market."

UTR website: "UltraCharge replaces graphite used for the anode (negative pole) with Ultracharge’s nanotube gel material made from titanium dioxide. Titanium dioxide, an abundant, cheap and safe material commonly used as a food additive and in sunscreen lotions to absorb harmful ultraviolet rays.

Naturally found in a spherical shape, UltraCharge has patented a unique but simple method to turn titanium dioxide particles into tiny nanotubes a thousand times thinner than the diameter of a human hair."
