    摘要: A process for making an electrode sheet for lithium electrochemical cells is disclosed. The process comprises the steps of : a) admixing a polyether polymer or copolymer soluble in water, at least one lithium salt, at least one electrochemically active material and water to form a water-based solution/suspension containing by weight at least 20% active electrode material, at least 5 % of a polyether polymer or copolymer, and at least 1.5 % lithium salt; b) coating the water-based solution/suspension in the form of an electrode thin film onto an electrode support; and, c) drying the electrode thin film to obtain an electrode thin sheet having less than 1000ppm of residual water. The electrode thin sheet thereby formed has less than 10% porosity after drying. The drying step is preferably carried out through a dryer/oven tunnel having incremental drying zones.
