【摘要】 多壁碳纳米管由于其优异的电化学性能而被广泛作为添加剂添加到电池中。本文尝试将多壁碳纳米管以质量分数0.02wt%加入到胶体蓄电池电解液中,探究其对胶体蓄电池的性能影响。通过胶强、胶体粘度以及电化学性能的测量,结果显示:多壁碳纳米管能够促进二氧化铅在铅电极上的生长,抑制一氧化铅的生长,使铅电极的析氢过电位增大而降低了析氧过电位。此外,粘度测量显示,碳纳米管促使胶体粘度增大,使其三维网络结构更加稳定。更多还原

【Abstract】 In this study,multi-walled nanotubes（WMCNTs） were used as additive at a mass ratio of 0.02wt.%in gel valve-regulated lead-acid（GEL-VRLA） batteries.The electrochemical performance of the gelled electrolytes were evaluated by means of cyclic voltammetry（CV）,linear sweep voltammetry（LSV）,and electrochemical impedance spectroscopy（EIS）.It is indicated that the addition of MCNTs can promote the growth of PbO₂,and inhibit the growth of PbO.However,the over-potential of hydrogen evolution reaction was increased,when the over-potential of oxygen evolution was decreased.The three-dimensional network became more stable due to the additive.更多还原
