Yeah. It's a subset of Li-ion. Tesla vehicles use NCA and their stationary storage products use NMC [1]. They are pretty similar but NCA is lighter and cheaper and NMC has better cycle life (and hence long-term value). It makes sense to use NMC for this application since weight is a non-issue.
They're both significantly cheaper than LCO (the most common) and because of that NMC has become a lot more common than it was. They're also much better behaved (ie happy to put out high-power bursts, temperature-stable, and less likely to ignite), but last longer than other chemistries like FePO4 (which not well behaved but quite hard to ignite).
