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.

Abstract: An electrochemical cell battery is disclosed having current collecting terminals acting as security device. The battery includes a plurality of electrochemical cells connected in series or parallel; each electrochemical cell having a current collecting terminal connecting the positive current collectors together and a current collecting terminal connecting the negative current collectors together; the current collecting terminals each having a folded extension arm for electrically connecting two adjacent electrochemical cells together. The current collecting terminals utilize layers of PTC materials strategically positioned whereby if a temperature of an electrochemical cell rises above the transition temperature of the layer of PTC material, electrical current is prevented to flow between electrochemical cells by the layer of PTC material.
