The CO2capture proposal targets limitations in our basic understanding of operation of alkalic metal-CO2 battery.

The Li–CO2 and Na–CO2 batteries represent a promising technology that can potentially achieve energy conversion-storage and CO2 recycling simultaneously. The proposed concept assumes development of proof-of-concept CO2 battery with integrated 1-D nanotubular electrode for effective accumulation of discharge products during battery operation. The variation of two compartment electrochemical cell assumes studies of Mn and Fe base perovskites, i.e. (La, Sr)(Mn, Fe)O3-? catalyst which is exceptionally active in terms of catalytic reactions in alkaline electrolytes. Fundamental studies towards understanding of chemistry on positive battery electrode is going to be studied by means of in-situ Raman spectroscopy and operando EXAFS at SPRING8 synchrotron facility, Hyogo, Japan.

The expected outcome of CO2capture project is development of proof-of-concept Na-CO2 battery that integrate energy storage with CO2 recycling, a promising technology in realizing carbon neutrality goals.
