Sort of. Compact NMC Li-ion cells from laptops and phones often use stuff like cobalt, supplies of which are much more limited and problematic than of lithium. The newer LiFePO4 chemistry does not use it, and, importantly, is rather hard to ignite. Its energy density per unit mass is lower, but it's not that important for stationary installations.
