摘要:
The method for fabricating an electrochemical device includes the following successive steps: a first stack successively including a first electrode and an electrically insulating electrolyte having a first main surface in contact with the first electrode and an opposite second main surface; a polymerisation step of the electrolyte so as to define at least a first area presenting a first degree of cross-linking and a first cross-linking density and a second area presenting a second degree of cross-linking different from the first degree of cross-linking and/or a second cross-linking density different from the first cross-linking density, said at least first and second areas connecting the first main surface with the second main surface; and placing the second electrode in contact with the electrolyte.
摘要:
The present invention provides a solid-liquid electrolyte in the form of a gel which comprises an organic carbonate-based solvent, precipitated silica, at least one ionically conducting salt and optionally additives. The invention also relates to batteries containing said solid-liquid electrolyte. The solid-liquid electrolyte according to the present invention can improve the electrochemical properties of batteries and prevent electrolyte leakage thus reducing the risk of corrosion of the batteries.

A polymer gel electrolyte includes an electrolyte solution composed of a plasticizer with at least two carbonate structures on the molecule and an electrolyte salt, in combination with a matrix polymer. Secondary batteries made with the polymer gel electrolyte can operate at a high capacitance and a high current, have a broad service temperature range and a high level of safety, and are thus particularly well-suited for use in such applications as lithium secondary cells and lithium ion secondary cells. Electrical double-layer capacitors made with the polymer gel electrolyte have a high output voltage, a large output current, a broad service temperature range and excellent safety.

The present invention provides a zero-emission electric power generating element using volcanic ash which is needless to treat waste batteries and is capable of regenerating electric energy and further provides an apparatus for controlling a group of batteries formed by the elements while seeking the best use of static electricity of volcanic ash. According to the present invention, a static electricity generating member (17b) comprising fine hollow powder (10a) made out of volcanic ash (10), other mineral ores (11c) and activated mineral water (11b) containing minus ion and a electrically conductive wet pulverulent body (30) comprising active carbon, fullerene or nanotube are filled into a insulative and sealable cylindrical container (31). The filled container is capped with an anode (15a) and a cathode (15b) and sealed so as to prevent gas or moisture from permeating.
