Hi, If this is real, then my guess as to it's makeup is as follows.
Anode: Sodium metal Cathode: Probably Sodium Permanganate Electrolyte: Probably a very thin MOF composite. Current "takeoff" from each electrode: Graphene. The chemistry provides the 4.2 V and specific energy. The Graphene and electrolyte ensure the electrodes remain intact resulting in long life. Even if it doesn't quite reach 100000 cycles, there is still a good chance it will outlast many current batteries. By using a very thin MOF based electrolyte, the internal resistance can be kept very low, which combined with the graphene connectors ensures the high charge rate. 100C is about as high as you would want to go with a permanganate cathode, but there are a few tricks that can be applied to protects the Permanganate at temperatures a bit higher. Sodium also performs better in the cold, explaining the -30C minimum. All of the chemicals used are relatively Earth abundant. Manganese is about as abundant as Nickel (but considerably cheaper) and 30 times more abundant than Cobalt ( and a great deal cheaper). Do unto others as you would have them do unto you for it you do not, They will do unto you as you do unto them
