Li–CO2 Batteries: Conjugated Cobalt Polyphthalocyanine as the Elastic and Reprocessable Catalyst for Flexible Li–CO2 Batteries (Adv. Mater. 2/2019)

In article number 1805484, Yanguang Li and co-workers develop cobalt polyphthalocyanine (CoPPc) as an elastic and reprocessable cathode catalyst for Li–CO2 batteries. This conjugated polymer facilitates the reversible formation and decomposition of Li2CO3 upon discharge and charge, and enables flexible Li–CO2 batteries with large areal capacity and impressive cycle life.
