It depends exactly where and how the battery is made—but when it comes to clean technologies like electric cars and solar power, even the dirtiest batteries emit less CO2 than using no battery at all.
“Batteries == Good” is my takeaway, but if you can be grid-tied I think zero batteries is the most environmentally friendly option. For grid stabilization I imagine even still that that should be left to utility-scaled installations.
Actually, now that I wrote that, this might be true for residential grid-tie vs utility solar too.
