They are testing a 26Ah battery pouch and were able to charge it at a 11C rate for 3 min and it retained 98.4% charge!!

I think the "it retains 98% charge" quote might be misleading. Thats true for the capacity (in Ah), but not for the energy (in Wh). The report shows this clearly in the tables:

Efficiency is about 83% if my math is right (which is still good).

Last paragraph

Under the specified test conditions, the cell was successfully charged at 5C for more than 9 minutes, and 100 % of the charged capacity was available during the subsequent discharge. The cell was also successfully charged at 11C for more than 3 minutes, with 98.4–99.6 % of the charged capacity available after a full charge.
