Abstract

Anode material has become the key issue for restricting the development of aqueous lithium ion battery (ALIB). Flake-like LiV3O8 materials were synthesized by sol-gel method using sodium dodecyl benzene sulfonate (SDBS) as a template. The XRD and SEM results showed that as-prepared flake-like LiV₃O₈ was of high purity with monoclinic system and P21/m space group. LiMn₂O₄//Li₂SO₄//LiV₃O₈ ALIB was assembled and tested. As observed, the flake-like LiV3O8 here exhibited good high-rate performance and cycling stability. A high discharge capacity of 154 mAh.g^-1 (based on the mass of negative electrode) was delivered at 0.1C (1C=300 mA.g^-1). At 1C, 5C and 10C rates, the reversible discharge capacities of 134 mAh.g^-1, 78 mAh.g^-1 and 54 mAh.g^-1 were retained, respectively. More importantly, the capacity retention after 170 cycles at 1C was about 60%.
