摘要:
The invention is related to a flexible transparent electrochromic device, which comprises the following components, each of which is a flexible film: a working electrode comprising a transparent conducting substrate supporting an working electrode active material; a counter electrode comprising a transparent conducting substrate supporting a counter electrode active material; a solid polymer electrolyte (SPE) comprising a solution of a lithium salt in a polymer solvent. Th method for preparing a said electrochromic device of the invention comprises the steps of: preparing a working electrode film, preparing a counter electrode film, preparing a polymer electrolyte film, and assembling the electrodes and the electrolyte, the method being implemented continuously.
摘要:
The invention concerns a polysaccharide-based solid material comprising, in its mass, at least one active agent having bactericidal, fungicidal, insecticidal and/or as flame retardant properties, and at least one complexing agent and/or at least one polymeric matrix including a complexing agent. The active agent consists of at least one compound selected among the group consisting of boron, silica, aluminum, phosphorus, iodine, derivatives thereof, aluminosilicate derivatives, and mixtures thereof. The solid material is characterized by its improved stability and by a reduced environmental impact, and enables wood particle- or wood-based materials having a particular resistance to environmental stresses such as moisture, to be prepared.
摘要:
The invention relates to a positive electrode material, consisting of particles having a complex oxide OC1 core, an at least partial complex oxide OC2 coating, and an adhesive carbon surface deposit. The material is characterized in that the complex oxide OC1 is an oxide having a high energy density and in that the oxide OC2 is an oxide of a metal having a catalytic effect on the reaction of the carbon deposit, the oxide having good electronic conductivity. The presence of the OC2 layer facilitates the deposit of a carbon adhesive layer at the surface of the oxide particles, and improves the conductivity of the material when the latter is used as an electrode material. The electrode material can particularly be used in the manufacture of a lithium battery.
