That is the case with every energy storage though in some cases it’s more pronounced.

Hold up, they solved the energy sink issue with the salt batteries? That’s wicked. There were physicists arguing with each other that the power you put in couldn’t be gotten back out.

Do you have more details about that?
theblueredditrefugee@lemmy.dbzer0.com 10 months ago
Yeah, I’m quite curious myself as to why it’s more difficult. My chemistry knowledge is chem1 level so all I know is that sodium atoms are larger and the energy levels for state change are slightly different

I left a very brief explanation as a reply to the other user.

Well, sure, but you’re asking me about something I saw in passing half a decade ago. Basically, the main difficulties with Na Ion Batteries and especially the “Glass Batteries” were the lack of proper cathode with which to create current and also maintain the structure against the naturally occurring atomic reshuffling. In particular there was controversy over John B. Goodenough’s research because other battery scientists noted the electrodes both ends contained anode materials which should theoretically produce no electrochemical potential and therefor no cell voltage.
More modern attempts appear to use Graphene structures, which is promising in a lot of different ways: structural stability, durability, current, and material availability.

So basically we didn’t have a material that could function as a cathode until now?

I’m not in the battery research field but I assume it’s kind of like
We’ve got tons of puzzle pieces that we need to put together
and then we need to find an economically viable create more combined puzzle pieces at scale.
