Is the lifespan of sodium-ion better than Li-ion?

They claim 2'000 cycles for their current 18650s, which, I believe, is about twice that of li-ions?

"Lithium Ion" encompasses a lot of chemistries. LFP, which is what is most competitive with sodium ion, has a cycle range of 3000-10000.

Depends on the anode
