Comment on Greener Alternative To Lithium-ion Battery

What is the energy density of this? It sounds like a rebrand of a hydrogen fuel cell, which has some limited applications, but has been supplanted by lithium-ion due to hydrogen’s low energy density and the fuel cells/electrolysis combo having poor energy efficiency.

The new proton battery has an energy density of 245 watt hours per kilogram, nearly three times the energy density of the team’s 2018 prototype

  Irrelevant to this discussion, though.
  
  How does it compare to competing technologies?

    You asked for the energy density, that’s why it’s relevant?
    
    For the rest of your questions, try Google?
