Fabricating electrochemical device by depositing lower electrode coating on substrate, depositing first electrochemically active layer on lower electrode coating, and depositing electrolyte layer on first electrochemically active layer

摘要

The process for fabricating an electrochemical device comprises depositing a lower electrode coating on a substrate, depositing a first electrochemically active layer on the lower electrode coating, depositing an electrolyte layer on the first electrochemically active layer, depositing a second electrochemically active layer on the electrolyte layer, depositing an upper electrode coating on the second electrochemically active layer, storing a lamination interlayer, drying the lamination interlayer for 24 hours, and introducing the interlayer and another substrate on substrate. The process for fabricating an electrochemical device comprises depositing a lower electrode coating on a substrate, depositing a first electrochemically active layer on the lower electrode coating, depositing an electrolyte layer on the first electrochemically active layer, depositing a second electrochemically active layer on the electrolyte layer, depositing an upper electrode coating on the second electrochemically active layer, where the first and second electrochemically active layers are adapted to reversibly pass between a first state and a second state of different optical and/or energy transmission by applying a power supply to the lower and upper electrode coatings and the upper and lower electrode coatings, the first and second electrochemically active layers and the electrolyte layer form a functional system with optical and/or energy electrocontrollable properties, storing a lamination interlayer, drying the lamination interlayer for 24 hours, introducing the lamination interlayer and another substrate on the substrate to cover the functional system, and heating the electrochemical device for collecting the substrate and another substrate through the lamination interlayer. The step of introducing the lamination interlayer and another substrate are performed in an atmosphere whose relative humidity level is maintained by = 5%. The drying step is performed in an atmosphere whose relative humidity level is maintained by ~20%. A water content of the lamination interlayer is decreased during the drying step. The relative humidity conditions of the drying step are maintained until the step of introduction of the lamination interlayer. The storing step is performed in an atmosphere whose relative humidity level is maintained by 25-30% until the drying step. The relative humidity of the atmosphere in the introduction, drying and/or storing steps is measured and controlled by a control device. The lamination interlayer is, after introduction step, present in contact with the upper electrode coating. The method further comprises introducing an electrical connector on the lamination interlayer, and cutting the substrate into several pieces. The first and second electrochemically active layers are activated by insertion/extraction of ions such as lithium ions. The cutting step is performed before the step of introduction of the lamination interlayer and another substrate and after the step of depositing the upper electrode coating. The lamination interlayer and another substrate are placed on the cutting pieces.
