I had a brief chat with Maria Helena Braga today. She was kind, as always, but could not tell me details, as it's confidential, about the energy density of this batteries that this partnership will try to produce using the Braga's electrolyte.
She told me that these batteries, using the solid electrolyte would have much less need of Control. Controls means the sysem to keep battery pack stable for charge, discharge, and in case very large packs, cooled to avoid overheat.
Remambering Tesla have a Control system, for the battery pack, very expensive, rivaling the cost of the battery itself.
