High-capacity zinc vanadium oxides with long-term cyclability enabled by in-situ electrochemical oxidation as zinc-ion battery cathode

LiV3O8 as an intercalation-type cathode for aqueous aluminum-ion batteries

“…While, Δ E s and Δ E τ are the change in steady state voltage and total change in cell voltage during the constant pulse of the solo-phase GITT, respectively. 41,42 Analysis of the GITT data led to a D Al coefficient of 4.09 × 10 −9 cm 2 s −1 for the LVO cathode for the discharge process (Fig. 5b), which is close to those reported for divalent charge carriers.…”

Conductive coating, cation‐intercalation, and oxygen vacancies co‐modified vanadium oxides as high‐rate and stable cathodes for aqueous zinc‐ion batteries

“…[4][5][6][7][8] In this case, developing the cathodes for ZIBs with superior discharge capacity, excellent rate performance, and long cyclic stability is crucial and plays a significant role on improving overall electrochemical properties of ZIBs. 9,10 To date, the desirable materials for ZIBs mainly include multivalent Mn-based oxides (e.g., MnO 2 , Mn 2 O 3 , etc. ), V-based composites (e.g., V 2 O 5 , VO 2 , etc.…”

Tuning ionic conduction and structure stability of ammonium vanadate by intercalating polyaniline molecules for advanced aqueous zinc-ion batteries

“…Currently, layered vanadium oxide materials exhibit enormous competitiveness as the cathode of AZIBs and attract wide research attention, originating from the unique open layer structure facilitating Zn 2+ diffusion and storage as well as the multiple oxidation states of vanadium providing higher specific capacity. 17 To further improve their electrochemical performance, various metals including (Zn 2+ , 18 Ni 2+ , 19 Ca 2+ , 20 Fe 2+ , 21 and Cu 2+ (ref. 22)) are pre-inserted into the interlayer as pillars to enlarge the corresponding interplanar spacing and enhance the crystal structure stability.…”
