1. A method for manufacturing a doped LMO sorbent spinel, the method comprising steps of:
a. providing a doped precursor blend, wherein the doped precursor blend is a 3:4 molar ratio of lithium to manganese, wherein the lithium source is LiOH monohydrate or Li2CO3 and the manganese source is a Mn3O4 blend with a 0.3% molar replacement of a doping agent for manganese;
b. calcining the doped precursor blend for an initial calcining duration and at a first calcining temperature of at least 500° C., wherein the calcining forms a doped intermediate-state sorbent blend of at least Mn2O3 and a doped LMO; and
c. calcining the doped intermediate-state sorbent blend for a second calcining duration and a second calcining temperature thereby forming a doped sorbent blend.
