A positive electrode material, having 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.

Material consisting of composite oxide particles, method for preparing same, and use thereof as electrode active material

A flexible transparent electrochromic device, which includes 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 including a transparent conducting substrate supporting a counter electrode active material; a solid polymer electrolyte (SPE) including a solution of a lithium salt in a polymer solvent. A method for preparing an electrochromic device includes 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.

Flexible transparent electrochomic device, and a method for the preparation thereof

The invention relates to an electrochromic optical lens and a method for the preparation thereof. The lens includes an electrode and a counter-electrode bearing an electrochromic material separated by a solid polymer electrolyte. The method consists of preparing the electrode and the counter-electrode and the assembly thereof by the surfaces thereof bearing the electrochromic material by interleaving an electrolyte membrane between said surfaces. The electrolyte membrane is interleaved in the form of a composition free of volatile liquid solvent, including a precursor of the polymer and a salt, which is liquid or which has a dynamic viscosity [mu] between 100 and 106 Pa&#xb7;s.

Process for treating wood consisting in injecting in cavities of the wood a solution of at least one fungicide and/or bactericide and/or insecticide and at least one monomer that can progressively form a polymer matrix in the cavities of the wood and then a gel in the cavities of the wood. The treated woods thus obtained exhibit an improved lifetime.

Process for treating wood for increasing the lifetime thereof and wood thus obtained

A polysaccharide-based solid material including, in its mass, at least one active agent having bactericidal, fungal, insecticidal and/or flame-retardant properties, and at least one complexing agent and/or at least one polymeric matrix having a complexing agent. The active agent includes at least one compound selected from the group including boron, silica, aluminum, phosphorus, iodine, derivatives thereof, aluminosilicate derivatives, and mixtures thereof. The solid material is characterized by an improved stability and by reduced environmental impact, and makes it possible to prepare materials based on wood particles and woods having a particular resistance against environmental attacks such as moisture.

Polysaccharide-based impregnated solid material with improved stability, processes for the preparation thereof and impregnating solutions used

A wood article is submitted to a vacuum in an autoclave to remove air that it contains. Then, a solution which contains a wood preservative, a water-soluble cross-linkable prepolymer and a polymerization initiator is introduced into the autoclave. Polymerization to form a polymeric network in the wood article is carried out in an atmosphere substantially free of oxygen, while the preservative is chemically fixed to the wood. The result is a wood article with a permanently reduced hardness and an increased moisture content at equilibrium.
