Starting date of the patent: 1987.10.28
Electrode electrical energy storage device includes a collector, active carbon and carbon black. Electric power storage electrode is in the form of separate layers of active carbon and carbon black. Soot layer is located between the current collector and a layer of active charcoal at ratios of layer thicknesses: black - activated carbon 1: 4-1: 100.
The technical result - reducing the contact resistance at the interface between the active mass of the electrode - collector.
DESCRIPTION OF THE INVENTION
The invention relates to electrical engineering and can be used for the manufacture of electrochemical devices.
Known electrochemical electrode device comprising a layer of activated carbon collector.
However, the electrochemical device comprising such an electrode has a high electrical resistance, which is due to the high contact resistance at the interface between the collector electrode due to poor contact of active carbon particles to the surface of the collector, due to their low dispersion.
Known electrode capacitor layer comprising a mixture of active carbon soot collector. (Japan, vz №5757120 cl H 01 G 9/00, 26.5.82, the -.. A prototype).
An electrochemical device comprising an electrode prototype has a high electrical resistance, which is due to the high contact resistance at the interface mixture layer section with activated carbon soot - collector due to poor contact between them. Poor contact layer of active carbon particles mixed with carbon black particles having a heterogeneous dispersion, due to the formation of the uniform surface layer of the particles, the presence of the porous portions.
The purpose of the invention - reducing the contact resistance at the interface between the active mass of the electrode - collector.
P left object is achieved in that the electrode storage of electrical energy comprising a current collector, active carbon, carbon black, is in the form of separate layers of active carbon and carbon black, wherein the carbon layer is located between the layer of active carbon and the current collector at the ratios of layer thicknesses: black - activated carbon 1 : 4-1: 100.
The application of the electric energy storage electrode has the following advantages over the prior art:
1. greatly reduced electrical resistance of the drive;
2. greatly reduced contact resistance at the interface between the active mass of the electrode - collector.
Production of electricity storage electrode in the form of separate layers of activated carbon and soot and soot layer arrangement between the active carbon layer and the collector, the thickness of layers with a ratio of 1: 4-1: 100, greatly reduces the electrical resistance of the drive by significantly reducing the contact resistance at the interface section of the active mass of the electrode - collector, due to a significant improvement in the contact between them. Improved contact electrode current collector surface is due to the presence in the contact zone between the layer of carbon black particles having a high dispersibility, homogeneity than the particles of active carbon or a mixture with carbon black, which greatly increases the contact area between the collector and the electrode, decreases the number of porous portions.
The contact resistance at the interface active mass of the electrode - collector increases in the ratio of layer thicknesses: black - activated carbon is greater than 1: 100 by a small amount of soot layer in contact with the current collector layer, which deteriorates the contact and reduces the contact area.
Contact resistance not changed when the ratio of layer thicknesses soot - activated carbon equal to 1: 4, due to good contact between the carbon layer and the current collector.
Features of the invention are not found in the literature.

The drawing shows a proposed electrode composed of one layer of active carbon, soot layer 2, a collector 3, in the ratio of layers: black - activated carbon 1: 4-1: 100. For comparative data electrodes were fabricated having a collector, active carbon, carbon black, made in the form of separate layers, with the location of the soot layer between the active layer and the carbon current collector in a ratio of layer: black - activated carbon 1: 3; 1:50; 1: 120, and an electrode comprising a collector and a layer of active carbon and carbon black mixture (prototype). |
By using the proposed electrode and electrode-going prototype electric energy storage devices and determine their electric resistance, evaluating the contact resistance at the interface between the active mass of the electrode - collector. The data obtained are presented in the table.
Thus, as can be seen from the table, drive electric power, an electrode which comprises a collector in the form of active composition: carbon, carbon black, made in the form of separate layers, and with the location of the soot layer between the layer of active carbon and the current collector at a ratio of layer thicknesses: black - active carbon 1: 4-1: 100, it has a much lower electrical resistance due to a significant reduction in the contact resistance at the interface active mass of the electrode - collector.
CLAIM
Electric power storage electrode comprising a collector successively with the contact placed on it and the active layers, characterized in that, in order to reduce contact resistance, the ratio of the thickness of the contact layer to the thickness of the active layer is selected in the range of 1 ÷ 4-1 ÷ 100.
