A soft chemistry synthesis and electrochemical properties of LiV3O8 as cathode material for lithium secondary batteries

Topotactically synthesized ultralong LiV3O8 nanowire cathode materials for high-rate and long-life rechargeable lithium batteries

“…[16][17][18][19] During the past 30 years, many methods have been proposed to improve the electrochemical properties of LiV 3 O 8 with different morphologies. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] However, LiV 3 O 8 nanowires with large aspect ratios and surface areas, which are supposed to have a desirable high-rate performance when used as the cathode material in rechargeable Li batteries, have rarely been reported. 22 H 2 V 3 O 8 (reported as V 3 O 7 Á H 2 O; however, from a structural point of view, the formulation H 2 V 3 O 8 is more appropriate than that of V 3 O 7 Á H 2 O 37 ) nanowires were reported to have a particularly ultralong one-dimensional morphology and a layered crystal structure similar to LiV 3 O 8 , 38 which allow the topotactic Li intercalation to form LiV 3 O 8 .…”

Synthesis and electrochemical performance of LiV3O8/polyaniline as cathode material for the lithium battery

“…The layered lithium vanadium oxide, LiV 3 O 8 has received considerable attention as cathode material in rechargeable lithium batteries due to its excellent electrochemical performances: high specific energy density, high working voltage, high discharge capacity, good chemical stability in air, ease of fabrication and low cost [1][2][3][4]. It is well understood that the electrochemical properties of lithium vanadium oxide are largely depend on the preparation method.…”

“…It is well understood that the electrochemical properties of lithium vanadium oxide are largely depend on the preparation method. Therefore, many preparation methods have been studied to LiV 3 O 8 with an aim to improve its electrochemical performance, such as spray pyrolysis method [5], sol-gel method [6][7][8], microwave-assisted synthesis [9], ultrasonic treatment [4] and hydrothermal synthesis [10]. Recently, Liu et al [11] employed home-made VO2 nanorods as the vanadium precursor to prepare the LiV3O8 cathode materials.…”

Review on Synthesis, Characterizations, and Electrochemical Properties of Cathode Materials for Lithium Ion Batteries

“…Since thermal stability in polymeric electrolytes is one of the main advantages for vanadium oxide, a variety of conductive polymeric materials have been suggested to be used as hybrid hosts of V 2 O 5 such as polypyrrole [104,112,114], poly(ethylene glycol) [116], polythiophene [109], polyphosphazene [159], and polyaniline [115]. Such polymeric hybrid materials have been found to increase the electronic conductivity of the original oxides and improve the cycling behavior by enhancing the microstructural stability.…”

“…In order to enhance the electrochemical properties of the material synthesized by increasing surface porosity and lowering crystallinity, several techniques have been suggested such as ultrasonic treatment [166] and partial crystalline modification by introducing small amounts of H 2 O, CO 2 and NH 3 [167]. Such techniques, although have improved the electrochemical behavior of LiV 3 O 8 to some degree, need further optimization in order to produce satisfactory power and cycling efficiency and to be applicable in large-scale production systems [159].…”
