摘　　要：采用SEM、EDS、IR、TGA/DSC、固含量及pH分析方法对木素进行理化性能分析。将工作电极及对电极置于分别溶解不同木素的1.285 g/cm^(3)稀硫酸溶液中成三电极体系,对其进行循环伏安(CV)、线性扫描(LSV)及电化学阻抗(EIS)分析。装配2 V 10 Ah样品电池进行连续17.5%DoD循环寿命性能测试,验证出有利于铅酸蓄电池循环寿命的木素。通过对木素的理化性能和电化学性能进行综合分析,得出了更适合的木素性能的表征方法。The physicochemical properties of lignin were analyzed by SEM,EDS,IR,TGA/DSC,solid content and pH value.The working electrode and the opposite electrode were placed in 1.285 g/cm^(3) dilute sulfuric acid solution dissolved in different lignins to form a three-electrode system,and the cyclic voltammetry(CV),linear scan(LSV)and electrochemical impedance(EIS)analysis were performed.A continuous 17.5%DoD cycle life performance test was performed on a 2 V 10 Ah sample battery,and the lignin favorable to the cycle life of lead-acid batteries was verified.Through comprehensive analysis of physicochemical properties and electrochemical properties of lignin,a more suitable characterization method for lignin properties was obtained.
