"Enormous hopes are linked to electric cars as the solution to the automotive industry’s climate problems.
However, electric car batteries are eco-villains during their manufacturing. 
Several tons of carbon dioxide (CO2) are generated even before the batteries leave the factory.
IVL The Swedish Environment Institute has, on behalf of the Swedish Transport Administration and the Swedish Energy Agency, investigated the climate impact of lithium-ion batteries from a life-cycle perspective.
The batteries for electric cars were included in the study.
The two authors—Lisbeth Dahllöf and Mia Romare—have done a meta-study, that is, reviewed and compiled existing studies.
The report shows that battery manufacturing leads to high emissions.

...Even before you buy the car, CO2 emissions equivalent to 5.3 tons and 17.5 tons, respectively, gets produced. 
...By way of comparison, a trip for a person returning from Stockholm to New York by air emits more than 600 kilograms of CO2, according to the UN organization ICAO’s calculation model.
Another conclusion of the study is that about half the emissions come from producing the raw materials and the other half from the battery factory.
The mining accounts for only a small proportion of between 10-20 percent..."
