A layered oxalatophosphate framework as a cathode material for Li-ion batteries†
Abstract
A new lithium containing hybrid inorganic–organic open framework material, Li2(VO)2(HPO4)2(C2O4), has been synthesized and its reversible lithium storage has been investigated. Firstly, the hydrated phase Li2(VO)2(HPO4)2(C2O4)·6H2O (1) was obtained via a hydrothermal route at 120 °C which on dehydration yielded the anhydrous phase. The crystal structure of 1 was solved and refined from its
