A new low-temperature synthesis and electrochemical properties of LiV3O8 hydrate as cathode material for lithium-ion batteries

LiV3O8 nanorods as cathode materials for high-power and long-life rechargeable lithium-ion batteries

“…It has been demonstrated that the electrochemical properties of LiV 3 O 8 are strongly dependent on how it is prepared, as well as on its particle size, morphology and crystalline texture. 19 In this regard, several methods have been developed to improve the electrochemical performance of LiV 3 O 8 cathode materials, including microwave synthesis, 20 solgel methods, 19 spray drying, 21 low-temperature synthesis, 22 hydrothermal method, 23 ultrasonic preparation, 24 etc. Enhanced Li storage capacity and rate performance have been realized by control of the morphology of nanostructured LiV 3 O 8 , 11,25,26 while the capacity retention and high-rate capability with long cycle life still need to be further improved in practice to satisfy highpower applications.…”

Nanosheet-structured LiV3O8 with high capacity and excellent stability for high energy lithium batteries

“…Lithium trivanadate (LiV 3 O 8 ) is another vanadium oxide that also can incorporate several lithium ions per formula. 13,18,19 In addition, the structure reversibility of LiV 3 O 8 is much better than that of V 2 O 5 , so it has good potential to obtain stable capacity during long cycling. The monoclinic structure of Li 1+x V 3 O 8 , first reported by Wadsley in 1957, 20 consists of (V 3 O 8 ) À layers oriented along a axis, connected by lithium ions at the octahedral sites in the interlayer.…”

“…10a) (Gu and Jian 2008), nanorods (Zhongxue et al 2017), spheres (Ju and Kang 2011) (Fig. 10b), and flake like (Feng et al 2009b). It has been demonstrated that the nanorods morphology with high crystallinity greatly improves the stability of the crystallographic structure during cycling (Liu et al 2009a).…”

“…Their final properties of the active material depend on the conditions and methods of synthesis, which include sol-gel (citric acid, C6H8O7 and (hydrogen) peroxide, H2O2) (Feng et al 2009a;andWang et al 2012), solution reaction (En-Hui et al 2004), solidstate (Feng et al 2009a), hydrothermal (Feng et al 2009a) (Liu et al 2007), aqueous precipitation (Feng et al 2009a), mechanochemical (Kosova et al 2001), microwave (Wu et al 2009), soft-chemical via a low-temperature heating process (Feng et al 2009b), spray pyrolysis (Ju and Kang 2011), and solid-state routine with quenching in freezing atmosphere (Liu et al 2009b).…”
