IONIC LIQUID ELECTROLYTE AND METHOD TO ELECTRODEPOSIT METALS

摘要

An electrolyte and a method to electroplate a metal on a substrate using the electrolyte are described. The electrolyte includes an imidazolium compound, a metal salt, and water. The imidazolium compound has formula (I) wherein R¹, R², R³, R⁴, and R⁵ are each independently selected from an H atom and an organic radical. L^- is a compatible anion. The metal salt can include but is not limited to salts of the metals Li, Mg, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb, Bi, La, Ce, Al, Ag, Au, Ga, V, In, Nb, Mo, and W.
