It’s an interesting question, let’s break it apart
Net energy produced requires a net reaction; even if an ‘AC Battery’ could be instantiated you’d still need a net reaction to produce energy.
Imagine a ball rolling up and down a hill. Our hill has no friction, and our atmosphere provides no resistance.
Agreed. I don’t have reason to think the cell isn’t reproducible, but without a feasible mechanism it is impossible to ascribe an achievable energy density.
Sean: there still needs to be a demonstrative chemical difference between the beginning state and the end state. The _mechanism_ they ascribe does not have any chemical difference between states.
To be clear: I am not saying their system violates the first law. That is impossible. What I am saying is their analysis violates…
I’ve certainly seen this in practice and in passing mention in papers: do you have a good reference that details the phenomenon?
What I’m curious about is how selective for Li over Cu the glass truly is.
This is a plausible hypothesis and I agree: in fact if what the authors are showing is the breakdown (charge) and “reformation” (discharge) of electrolyte that would be pretty great.
Certainly a more palatable explanation with respect to thermodynamics.
hah: it’s right in the abstract:
We investigate phase stability and ionic transport mechanisms in two recently discovered superionic conductors, Li3OX (X = Cl, Br), from first principles. These compounds, which have an antiperovskite crystal structure, have potential applications as solid electrolytes in Li-ion batteries. We…
