It seems that the lithium is not consumed as the end product is C and O2. If the lithium electrode can process one CO2 per lithium every minute, then 1 mole of lithium would process about 500 kilomol of CO2 per year. Even if you need to replace the lithium a few times over the course of a year, this is not a bad deal. Electrochemical processes are fast. Therefore, the annual ratios are bit misleading. Dimensionally, you need the lifetime of the lithium electrode, and the time it takes to cycle a single Li through the cycle. The ratio between carbon processed and Li lost can be huge

Or if you have some spare, non-fossil electricity laying around you can always make lots of environmentally-beneficial metal (Mg or Ca) (bi)carbonates from globally abundant base minerals and air CO2, while generating C-negative H2: http://www.pnas.org/content/110/25/10095.abstract<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.pnas.org_content_110_25_10095.abstract&d=DwMFaQ&c=l45AxH-kUV29SRQusp9vYR0n1GycN4_2jInuKy6zbqQ&r=hFjA8A8KwwhQx5qilpfIleTL0XYVr_fckT8DnwIEWlQ&m=emrXUboyoBC1O58DNdC6KJ3FVvBq04EePwXoHaTllRk&s=pTQVvCxwT7YTaCCrkQQN7RycIx0fWxzKxeAx9oFhxWo&e=> OK, I’m not making elemental C or conc CO2, but I don’t think we need to.

Global lithium production last year amounted to less than 1 mole per capita Global lithium reserves are on the order of 1 kilomole per capita.
