Much improved capacity and cycling performance of LiVMoO6 cathode for lithium ion batteries

Brannerite-Type Vanadium–Molybdenum Oxide LiVMoO6 as a Promising Anode Material for Lithium-Ion Batteries with High Capacity and Rate Capability

“…18−20 Its electrochemical properties were once studied in different working voltages: Between 1.8 and 3.6 V, rodlike LiVMoO 6 nanocrystals delivered a stable capacity of 166 mAh g −1 at a current density of 200 mA g −1 over 100 cycles. 21 Though the reversible capacity is comparable with that of commercial LiCoO 2 , the low average working voltage at around 2.3 V definitely induces a low-energy density when utilized as the cathode in a full cell. When lowering the working potential to nearly 0 V, a high discharge capacity of nearly 1200 mAh g −1 was achieved.…”

“…LiMoVO 6 crystallizes in the ThTi 2 O 6 -type brannerite structure, where a quasi-2D structure is built up by the edge-sharing VO 6 and MoO 6 octahedra along b axis. Lithium ions are situated between the anionic sheets in LiO 6 octahedral sites. − Its electrochemical properties were once studied in different working voltages: Between 1.8 and 3.6 V, rodlike LiVMoO 6 nanocrystals delivered a stable capacity of 166 mAh g –1 at a current density of 200 mA g –1 over 100 cycles .

Magnetic field assisted chemical reduction preparation of Co–B alloys as anode materials for alkaline secondary battery

“…It provides the further evidence that the alloy prepared under the external magnetic field possesses the better electrochemical kinetic property, consequently increasing the Co/Co(OH) 2 reaction rate as well as resulting in an improvement in high-rate dischargeability and cycle performance. On the other hand, the reaction surface area of the electrode is another important factor that can affect the exchange current density [29].…”

Structure and electrochemical properties of LiMnBO3 as a new cathode material for lithium-ion batteries

“…Lithium-ion batteries, due to their low price, long cycle life, environmental safety and high specific energy [1][2][3][4], have triggered the growth of the consumer electronics market and now are the power sources of choice for many popular devices, including mobile phones, laptop computers, and Mp3 players. At present, most of commercial cells utilize cobalt-based oxides as the cathode material, but high cost and toxicity prohibit its large-scale use [5][6][7][8][9][10][11].…”
