Uhnn... the author of this news article suggested that it's not just the Goodenough&Braga electrolyte that will be used, but their battery design too :
"It is worth noting that the cooperation between Mercedes-Benz AG and Hydro-Québec involves solid-state batteries, not only the solid-glass electrolyte. That means that other research from Goodenough and Braga about that could also end up in Mercedes-Benz vehicles or even on Smart, which is now an EV-only brand under Geely’s responsibility.
That means we could see a solid-state cell that increases its energy capacity with time, as Goodenough and Braga announced back in 2018. More than that, these cells could be on Daimler vehicles as soon as they reach production status."

But it's not clear, since it can be a battery design from them or other, or even a new design from Goodenough&Braga partnering woth Hydro-Québec. So the author it's more guessing than concluding things.
Anyway Maria Braga couldn'tell me much, since details are confidential, but she said it would be more than just the use of their electrolyte.
I would expect a very nice advancement for batteries, in a year or two to market. But for the battery design able to increase capability after many charge/discharge cyclos, I believe it can take more time for get market.
