负极材料是目前制约水溶液锂离子电池的关键. 采用十二烷基苯磺酸钠软模板辅助的溶胶凝胶法制备了片状LiV₃O₈材料. XRD和SEM测试表明目标材料为纯相的片状结构LiV₃O₈，属单斜晶系，P21/m点群. 组装LiMn₂O₄//Li₂SO₄//LiV₃O₈水溶液锂离子电池，测试发现片状LiV₃O₈具有较高的倍率性能和较好的循环寿命. 在0.1C下，LiV₃O₈的放电比容量为154 mAh.g^-1. 在1C、5C和10C时，放电容量分别为134 mAh.g^-1、78 mAh.g^-1和54 mAh.g^-1. 1C下前170周循环的容量保持率约60%.

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%.
