Abstract: We have reinvestigated the polyanionic compound Na2Fe2(C2O4)3·2H2O, previously reported to be electrochemically inactive in lithium-ion batteries (LIBs), as a positive electrode for sodium-ion batteries (NIBs). The present study demonstrates that it is capable of delivering… read more here.

DOI: 10.1021/acs.inorgchem.2c03308
Abstract: A cathode material, Na2[(VO)2(HPO4)2(C2O4)]·2H2O, for aqueous zinc-ion batteries is synthesized by a hydrothermal method. Na2[(VO)2(HPO4)2(C2O4)]·2H2O presents a two-dimensional layered structure and sheetlike morphology, which provide fast and reversible Zn2+ insertion/extraction. Na2[(VO)2(HPO4)2(C2O4)]·2H2O delivers a high average… read more here.
