That's not what that link says. It says that hybrids deliver a larger CO2 reduction per unit of battery, and because batteries are scarce, we would do better CO2 reduction by focusing limited battery capacity in hybrid vehicles, as this would lead to the greatest number of miles traveled on electric charge, along with some savings from the weight of batteries. It definitely does not say that BEVs have higher emissions over the course of a car's life. It pretty clearly shows that BEVs have the largest decrease in CO2 emissions, as you would expect.
