Battery Manufacturing's Emissions Are Small Today and Could Grow by a Factor of 10 or More by 2050
A study led by Haiwei Zhou at the University of Melbourne examined the emissions created by making lithium-ion batteries, which many parts of the energy transition depend on. The researchers estimate those emissions currently account for 0.18 percent of annual greenhouse gas releases, and that they could increase by a factor of 10 or more by 2050.
Some of that energy use is embedded in the recipe: certain elements used in various lithium-ion chemistries take more energy to mine and refine than others. Recycling is the other obvious lever, since it can put battery materials back into the loop while requiring much less energy than mining them in the first place.

Recycling looks like the lever that pays twice: it keeps material in circulation with far less energy than mining, and mining is exactly where the chemistry you pick already drives the energy bill.
Fair, but the growth story is volume rather than wastefulness — those emissions aren't zero, and the more batteries get used, the larger that total becomes. This is the sort of category that starts to matter once the dominant slices of the emissions pie have shrunk.
