Lithium compounds
I'm pretty sure its Lithium Peroxide not Hydroxide that's used as the peroxide scrubs to the carbonate and oxygen in 2:1 redox stoichiometry.
The Hydroxide simply neutralises to the carbonate.
Forgive the lack of subscripts and yes I know it's ionic really but it goes like this
2Li2O2 + 2CO2 = 2Li2CO3 + O2
cf
Li(OH)2 + CO2 = LiCO3 + H2O
