水/乙醇取代传统具有毒性的有机溶剂,采用水基流延工艺制备多孔NiO阴极,研究造孔剂尿素和活性炭的添加量对孔隙率的影响.通过对电极孔隙率测定以及扫描电镜(SEM)分析,结果表明水基流延法能够制备出质地均匀的NiO电极,当活性炭与Ni的质量比为0.075时,NiO电极孔隙率达到最大值66.6%;而当尿素与Ni的质最比为0.05时,NiO电极最大孔隙率则达到了60.1%.
Porous NiO cathode was fabricated by aqueous tape-casting method using water/ethanol as solvent,which substituted the traditional organic toxicant,and the effects of pore-former contents of urea and active carbon on porosity were investigated.The determination of porosity and the analysis of scanning electron microscopy (SEM) indicated that NiO cathode prepared by aqueous tape-casting was homogenous.NiO cathode with 0.075 mass ratio of active carbon to Ni has the maximum porosity of 66.6%,when the mass ratio of urea to Ni Was 0.05,the maximum value of porosity is 60.1%.
