The cost to making batteries includes the 'formulation' step that is a series of charge-discharge cycles in a thermally controlled environment. Traditionally, this has increased the amount of CO{2} attributed to building an EV. However, Tesla has a new patent that substantially reduces this battery manufacturing CO{2} cost:

The model was developed by the Argonne National Laboratory in Chicago and includes thousands of parameters from the type metals in an electric vehicle (EV) battery to the amount of aluminium or plastic in a car.
Argonne's Greenhouse Gases, Regulated Emissions and Energy Use in Technologies (GREET) model is now being used with other tools to help shape policy at the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board, the two main regulators of vehicle emissions in the United States.
Jarod Cory Kelly, principal energy systems analyst at Argonne, said making EVs generates more carbon than combustion engine cars, mainly due to the extraction and processing of minerals in EV batteries and production of the power cells.
