Cell manufacturers have been reducing the cobalt content of their cathode material for years, with "NCM811" (80% nickel, 10% cobalt, 10% manganese) being the current aspiration for many. Tesla claims it's cells already use significantly less cobalt again. Other cell chemistries, like Lithium-Iron-Phosphate (LiFePO4) use no cobalt at all.
