The present invention relates to an improvement of a plastic electrode secondary battery using a polyacetylene film as an electrode. Polyacetylene is the simplest chain conjugated polymer compound with one carbon and one hydrogen atom as a constituent unit, and has semiconductor properties, but it is especially suitable for the Ziegler-Natsuta catalyst (Ti(OC 4 H 9 ) 4 −Al
The polyacetylene film produced by acetylene polymerization using (C 2 H 5 ) 3 system) has a fibril (fibrous microcrystal) network structure with a diameter of about 200 Å, and a small amount of halogen gas or arsenic pentafluoride is added to this film. By applying specific doping, the conductivity can be changed over a wide range. Therefore, such polyacetylene membranes are chemically extremely stable, lightweight,
Due to the fibril network structure mentioned above, it can take up a very large surface area.
It is already attracting attention as a promising electrode material for secondary batteries. However, in conventional plastic secondary batteries of this type, a polyacetylene membrane electrode from which a positive terminal is derived and a polyacetylene membrane electrode from which a negative terminal is derived are placed opposite each other in a container, and a separator is sandwiched between the two electrodes. , which uses an electrolyte in which lithium perchlorate (LiClO 4 ) is dissolved in propylene carbonate (PC), and it is true that lead-acid batteries have a cell voltage of 2.1V and an energy density of 30Wh/Kg. , the performance is about 200 to 300 charge/discharge times, while the cell voltage is 2.5V, the energy density is 150Wh/Kg, and the maximum output density is 17KW/Kg.
Kg, energy efficiency of 80%, and charge/discharge cycles of approximately 300 times, its characteristics have been significantly improved and it can be made lightweight. However, the above-mentioned performance cannot be said to be satisfactory, and the applicant has already proposed a plastic electrode secondary battery that can greatly improve the above-mentioned characteristics. That is, as shown in FIG. 1, a container 1 in a closed state is formed of a rigid resin such as polyethylene.
A gas vent hole 2 is provided in the ceiling wall of the container 1, and inside the container 1 there are a polyacetylene membrane electrode 4 conductive to the positive terminal 3 led out to the outside, and a polyacetylene membrane electrode conductive to the negative terminal 5 led out to the outside. 6 and a separator 7 made of a glass fiber filter sandwiched between both electrodes, and an electrolyte 8 containing lithium perchlorate dissolved in propylene carbonate (concentration 1 normal) as described above. is included. Furthermore, an auxiliary positive electrode 9 made of gold and an auxiliary negative electrode 10 made of an aluminum piece are bonded to the outside of the positive and negative polyacetylene membrane electrodes 4 and 6, respectively, by vapor deposition.
Both polyacetylene membrane electrodes 4, 6 are composed of a desired plurality of polyacetylene membranes 4', 4'..., 6', 6...
It is constructed by gluing... Here, the above polyacetylene films 4', 4'...
..., 6', 6'... The polyacetylene membrane electrodes 4 and 6 and the auxiliary positive electrode 9 and the auxiliary negative electrode 10 are fixed by means such as pressure bonding or ultrasonic bonding. When manufacturing the battery, the separator 7 made of a glass fiber filter, the auxiliary electrodes 9 and 10, and the container 1 were vacuum-dried in advance, the PC was dried under reduced pressure, and the lithium perchlorate was dried in a vacuum for 5 hours. After dehydration, vacuum drying is performed for 24 hours. The electrode reaction is as follows, with the right arrow below indicating discharging and the left arrow indicating charging. [CH (ClO - 4 ) y ] x +XY - e (CH) x +XYClO - 4 ...Positive electrode [CH (Li + ) y ] x (CH) x +XYLi + +XY - e ...Negative electrode [CH (ClO - 4) ) y ] x + [CH (Li + ) y ] x 2 (CH ) x +
~3.5V, the energy density is 424Wh/Kg, which has greatly improved characteristics compared to conventional products without auxiliary electrodes, the maximum output density has increased to 24.5KW/Kg, and the energy efficiency remains unchanged at 80%. value was shown. Furthermore, it was confirmed that the short circuit current was significantly increased as shown in the table below, even under the same charging conditions, compared to the case where a single polyacetylene membrane electrode was used. The values in the table below indicate the case with a charging current of 0.5 mA/cm 2 , and the polymerization temperature during polyacetylene membrane production was -78°C, the pressure was 760 mmHg, and the polymerization time was approximately 5 minutes.
Furthermore, the bulk density of the produced polyacetylene membrane is
The film thickness is 0.3 g/cm 3 and 70 to 80 μm.

The purpose is to make the properties improved as described above even better by appropriately selecting the surface density of the polyacetylene film. Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. In the present invention, a polyacetylene film 4' in contact with the auxiliary electrodes 9 and 10 of the positive and negative electrodes is used in a secondary battery having the same structure as that shown in FIG. ,4'...
..., 6', 6'... polyacetylene film 4', 4'..., 6', which is in contact with the separator 7
6'... is made higher than the surface density. Therefore, in order to manufacture the above polyacetylene membrane,
For example, the catalyst has an Al/Ti molar ratio of 4:
1, two types of Zieglernatu catalysts (Ti/OC 4 H 9 ) 4 -Al with Ti concentrations of 100 mmol/ and 600 mmol/
(C 2 H 5 ) 3 system) was used. Further, the polymerization was carried out under conditions of a pressure of 1 atm and a temperature of -78°C. The structure of the polyacetylene film was such that an inert gas (not shown) was sealed in a polymerization bottle, and the polymerization bottle was rotated at approximately 100 rpm in a vertical position. That is, first, while rotating the polymerization bottle filled with inert gas, the Ti concentration was injected from the catalyst injection port.
Drop 1ml of 600mmol/catalyst onto the bottom of the polymerization bottle, stop the rotation when the catalyst spreads to the bottom, exhaust the inert gas, and add 10ml of acetylene gas.
The first layer of polyacetylene film was produced by introducing the solution for a few minutes. Next, while rotating the polymerization bottle, 1 ml of catalyst with a Ti concentration of 100 mmol/l was dropped from the catalyst injection port onto the surface of the polyacetylene film of the first layer in the polymerization bottle, and polymerization was carried out in the same manner as above. A polyacetylene film having a density different from that of the first layer of polyacetylene film is formed on the first layer of polyacetylene film. The second layer polyacetylene film B produced by the above method has a low surface density as shown in FIG. 3, whereas the first layer polyacetylene film A has a low surface density as shown in FIG. As shown, the surface density is increasing. In other words, in the case of the same membrane B, the hollow part B' is small and the fibrous part B'' is large, whereas in the above membrane A, the fibrous part A'' is small and the hollow part A' is large. The polyacetylene film B is placed in contact with the positive and negative auxiliary electrodes 9 and 10 as described above, and the polyacetylene film A is arranged in contact with the separator 7 side. Table 1 shows the polyacetylene films 4', 4'..., 6', positive electrode and negative electrode in the secondary battery shown in FIG.
6', the short circuit current values are shown when the surface density is varied and the batteries are charged for one hour. Here, the charging current is 2 mA/cm 2 .

It can be seen that if the film surface density of 4'..., 6', 6'... is increased, the contact area with the bipolar auxiliary electrode increases, and the short circuit current value increases. Ta. As embodied in the above embodiment, the present invention provides a plastic electrode secondary battery using polyacetylene membranes 4' and 6' as electrodes, in which the surface densities of the polyacetylene membrane electrodes 4 and 6 of the positive and negative electrodes are different from each other. Since it is larger than the polyacetylene films 4', 6' which are in contact with the auxiliary electrodes 9, 10 of As a result, the short-circuit current value increases, and the hollow portion of the polyacetylene membrane electrodes 4 and 6 as a whole becomes extremely small, so that the contact area between the electrolyte and the membrane electrode is not reduced. A plastic electrode secondary battery that can withstand heavy loads can be provided.
