Abstract The search of new multifunctional cathode materials, with new crystal structures and compositions, for lithium ion battery is extremely important to mitigate the drawbacks associated with the current electrode materials used in rechargeable lithium ion batteries. In this paper, orthovanadate family CrVO4 has been identified and investigated as a new cathode material for high-rate and high-capacity lithium ion battery for the first time. A solution-based effective and versatile synthetic protocol has been proposed to synthesize CrVO4 nanoparticles. Physical characterizations reveal that the prepared CrVO4 consists of uniform and discreet nanoparticles of crystallite size ~ 19 nm with widespread pore diameter, enhanced conductivity and surface area. The prepared CrVO4 nanoparticles have been evaluated as a potential cathode material for lithium ion batteries, wherein the experimental results demonstrate enhanced lithium storage with high rate-capability and cyclability. The experimental results reveal that the proposed CrVO4 is working through a partial conversion reaction mechanism. Keywords Rechargeable battery . Chromium vanadate . Positive electrode .

Introduction Despite the great success in the commercialization of lithium ion battery technology, the performance of the lithium ion battery, based on the traditional cathode materials, is approaching the limit [1, 2]. Therefore, the search of novel multifunctional cathode materials with new crystal structures and

compositions is extremely important to meet the ever growing demands of portable electronics, electric vehicles, and grid applications. Among the cathode materials, intercalation compounds have been widely studied owing to their structural flexibility and adoptable interlayer space, which endows the smooth insertion and excretion of Li+ ions and thereby making them suitable for real applications. Layered cathode materials, which store more than one Li+ ion per transition metal seem to be an ideal candidate for lithium ion battery [2]. In this regard, vanadium-based oxides draw considerabl
