Synthesis and performance of Li1.5V3O8 nanosheets as a cathode material for high-rate lithium-ion batteries

Mo-doped LiV3O8 nanorod-assembled nanosheets as a high performance cathode material for lithium ion batteries

“…Such a result is in a good agreement with the previously reported studies, 34,57,58 which widely report a quick capacity loss in the initial cycles for pure LiV 3 O 8 . Wang et al 59 reported Li 1.5 V 3 O 8 nanosheets with an initial capacity of 204 mA h g À1 at a current density of 175 mA g À1 , but it decreased to 100 mA h g À1 aer 100 cycles. Guo et al 60 reported LiV 3 O 8 with an initial capacity of 248.5 mA h g À1 at 300 mA g À1 ; however, the capacity faded to 105.2 mA h g À1 rapidly during the rst 50 cycles.…”

High Rate, Long Lifespan LiV3O8 Nanorods as a Cathode Material for Lithium‐Ion Batteries

“…It has been reported that the poor rate performance is mainly ascribed to the sluggish lithium diffusion kinetics . To address this issue, multiple electrode designs have been developed to enhance the lithium intercalation/deintercalation kinetics of LiV 3 O 8 , one effective strategy is to construct nanoarchitectures, such as nanowires, nanosheets, nanobelts, nanorods, etc. These nanostructures may provide shortened Li‐ion diffusion path and abundant electrode/electrolyte contact interfaces, leading to improved rate capability.…”

LixV2O5/LiV3O8 nanoflakes with significantly improved electrochemical performance for Li-ion batteries

“…The variations of the plateaus imply possible structure self-rearrangement during the cycling. improved rate performance here is not only superior to bare lithium vanadate, including LiV 3 O 8 25,48 and Li 1.5 V 3 O 8 , 49 but also much better than some of the carbon coated vanadates. 21 Idris et al 21 fabricated carbon coated LiV 3 O 8 nanosheets, which delivered a reversible capacity of 110 mA h g À1 at 5 C. It is worthwhile to note that our in situ transformation strategy has advantages over carbon coating.…”
