Abstract

Layered H2V3O8 material consisting of V3O8 layers features the elastic space for buffering volume change upon repeated ion (de)intercalations. However, its ion transport and phase transformations still remain largely unknown due to lack of direct evidence. Here we employ in situ transmission electron microscopy to revisit this material carefully. Upon lithiation, the localized phase transformation from H2V3O8 to V2O3 via an intermediate VO2 phase was observed, and large structural fissures gradually formed. Unexpectedly, the large fissures were able to self-heal during delithiation with the VO2 phase as the delithiated product. The fissures could appear and disappear alternately upon subsequent (de)lithiation, in which a stable and reversible phase transformation between V2O3 and VO2 phases was established. These unreported findings are expected to call for renewed attention to this electrode material for a more comprehensive understanding in rechargeable metal-ion batteries.
