【摘要】 为了研究隔膜扩散特性对全钒氧化还原液流单电池充放电性能的影响,利用设计的渗透池实验测定了VO2+和VO2+在两种离子交换膜中的扩散系数,约为10-9~10-7cm2/s。使用扩散系数较小的离子交换膜组成的钒电池,充放电性能较好,电流效率达到90%。更多还原

【Abstract】 In order to investigate the influence of membrane diffusivity on the charge-discharge performance of a single all vana-（dium） redox flow battery（VRB）,the diffusion coefficients of VO²⁺ and VO₂⁺ in two types of given ion exchange membranes were measured with a specific designed permeation cell,the diffusion coefficients were about 10^-9～10^-7 cm²/s.The VRB composed of the membrane with a lower diffusion coefficient showed better charge-discharge performance.Its current efficiency approached to 90%.更多还原
