Reaming corrosive liquid, corrosion process and electrode foil

The invention relates to a chambering corrosive liquid, a corrosion process and an electrode foil prepared by the corrosion process, belonging to the technical field of electrode materials for capacitors. The chambering corrosive liquid comprises gallium-based liquid metal nanoparticle dispersion liquid, the gallium-based liquid metal nanoparticle dispersion liquid is obtained by dispersing gallium-based liquid metal in a polymer solution of polystyrolsulfon acid and sodium polystyrolsulfonate, and the mass fraction of the gallium-based liquid metal is 0.3-1.5%. According to the electrode foil prepared by the corrosion process for chambering by using the chambering corrosive liquid, the hole depth is increased, branch holes or small holes are reduced, the consistency of the holes is good, and the electrostatic capacity and the bending strength are relatively high. 一种电容器用电极材料技术领域的扩孔腐蚀液、腐蚀工艺及由该腐蚀工艺制备的电极箔。扩孔腐蚀液包含镓基液态金属纳米颗粒分散液，镓基液态金属纳米颗粒分散液由镓基液态金属在聚苯乙烯磺酸和聚苯乙烯磺酸钠的高分子溶液中分散得到，其中，镓基液态金属的质量分数为0.3-1.5％。使用扩孔腐蚀液进行扩孔的腐蚀工艺
