Yes, please, they are very welcome for large energy storages. And as article states, not for anything that requires energy density (mobile devices, EVs and such).
- But do they catastrophically explode for no apparent reason?
  
  I mean, you can't have everything
Just give me the batteries nintendo put in the ds lites. I just brought out the broken hinge dsl while packing to move and powered it on. 100% battery after ?? years. Literally no other battery I have ever owned can do this even if disconnected.
- They're lithium ion. It's probably got more to do with good hardware design.
  
  I find it hard to believe that they kept 100% charge for years even if perfectly designed. 🤷‍♂️
