Single-crystalline (NH 4 ) 2 V 3 O 8 nanoflakes were successfully synthesized by a facile hydrothermal method. We investigated their electrochemical performance for use in lithium ion batteries for the first time. Interestingly, the as-prepared (NH 4 ) 2 V 3 O 8 electrode demonstrated good lithium storage properties. This material exhibited a high initial discharge capacity of 261.4 mAh g -1 at a current density of 150 mA g -1 . Apart from the capacity loss in the first two cycles, the discharge capacity remained relatively stable and a capacity of 215.8 mAh g -1 was maintained after 30 cycles, indicating good cycling stability. The Coulombic efficiency was close to 100 % during the cycling, revealing that the intercalation/deintercalation of Li ions in this material was highly reversible. The good electrochemical performance of (NH 4 ) 2 V 3 O 8 was mainly attributed to its flake-like morphology and intrinsically stable layered structure.

“…This can be traced back to a number of reasons: 1. In comparison to the other composite electrodes with reduced graphite oxide414243, there are common features arising from the RGO network that is expected to facilitate Li + ion as well as electron transports, prevent contact losses under extensive cycling and may act as a protective layer against cycling by-products. 2.…”

V2O5 based materials are attractive cathode alternatives due to the many oxidation state switches of vanadium bringing about a high theoretical specific capacity. However, significant capacity losses are eminent for crystalline V2O5 phases related to the irreversible phase transformations and/or vanadium dissolution starting from the first discharge cycle. These problems can be circumvented if amorphous or glassy vanadium oxide phases are employed. Here, we demonstrate vanadate-borate glasses as high capacity cathode materials for rechargeable Li-ion batteries for the first time. The composite electrodes of V2O5 – LiBO2 glass with reduced graphite oxide (RGO) deliver specific energies around 1000 Wh/kg and retain high specific capacities in the range of ~ 300 mAh/g for the first 100 cycles. V2O5 – LiBO2 glasses are considered as promising cathode materials for rechargeable Li-ion batteries fabricated through rather simple and cost-efficient methods.

“…In contrast, sodium‐ion batteries (SIBs) are considered as a promising candidate for GES, owing to the natural abundance of sodium. Additionally, the similar intercalation chemistry of SIBs and LIBs could lead to applicable electrochemical performance . Thus, many novel electrode materials have been developed, such as NASICON‐type compounds, Prussian blue, tunnel‐type Na 0.44 MnO 2 , and so forth .…”

As a promising positive electrode material for sodium-ion batteries (SIBs), layered sodium oxides have attracted considerable attention in recent years. In this work, stoichiometric P2-phase NaCo(0.5)Mn(0.5)O2 was prepared through the conventional solid-state reaction, and its structural and physical properties were studied in terms of XRD, XPS, and magnetic susceptibility. Furthermore, the P2-NaCo(0.5)Mn(0.5)O2 electrode delivered a discharge capacity of 124.3 mA h g(-1) and almost 100% initial coulombic efficiency over the potential window of 1.5-4.15 V. It also showed good cycle stability, with a reversible capacity and capacity retention reaching approximately 85 mA h g(-1) and 99%, respectively, at the 5 C rate after 100 cycles. Additionally, cyclic voltammetry and ex situ XRD were employed to explain the electrochemical behavior at the different electrochemical stages. Owing to the applicable performances, P2-NaCo(0.5)Mn(0.5)O2 can be considered as a potential positive electrode material for SIBs.
