  However, a battery using a nitroxy radical charge storage material as an electrode active material has a smaller charge storage capacity than that using an inorganic electrode active material, and a high capacity organic charge storage material such as an organic sulfur polymer. When used, there was a problem that the cycle performance was low. In addition, there have been almost no examples of organic charge storage materials having high atmospheric resistance in a reduced state that are necessary for application to negative electrodes of air secondary batteries.

  The present invention has been made in view of such circumstances. When used as an electrode active material, the present invention provides a benzoate having a charge storage property that can provide a high-performance battery having high capacity, high rate characteristics, and high cycleability. An object is to provide a dithiophenequinone polymer, a charge storage material comprising the same, an electrode active material using the charge storage material, an electrode including the electrode active material, and a battery using the electrode.

  As a result of intensive studies to achieve the above object, the present inventors have found that when an electrode containing a charge storage material composed of a benzodithiophenequinone polymer is used as an electrode active material, a high capacity, a high rate characteristic, and a high The inventors have found that a high-performance battery having cycleability can be produced and completed the present invention.

That is, the present invention
1. A benzodithiophenequinone polymer comprising a repeating unit represented by the following general formula (1) or (2):
(In the formula, X, Y and Z each independently represents an organic group formed by a polymerization reaction from a polymerizable functional group having a carbon-carbon unsaturated bond. R ^{1 to} R ⁵ are each independently a hydrogen atom. , A halogen atom, a hydroxy group, a mercapto group, an amino group, a substituted or unsubstituted alkyl group having 1 to 12 carbon atoms, a substituted or unsubstituted alkenyl group or alkynyl group having 2 to 12 carbon atoms, a 6 to 12 carbon atom A substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group having 3 to 12 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 12 carbon atoms, an alkylthio group or a monoalkylamino group, and each alkyl group. Independently represents a dialkylamino group which is a substituted or unsubstituted alkyl group having 1 to 12 carbon atoms or an alkylcarbonyl group having 2 to 12 carbon atoms. .)
2. Said X, Y, and Z are respectively independently following formula (3) or (4)
(R ^{6 to} R ⁹ are the same as the groups shown as R ^{1 to} R ⁵ above. The wavy line represents that the bond configuration may be either cis or trans.)
1 benzodithiophenequinone polymer which is a group represented by
3. 2 benzodithiophenequinone polymers wherein X, Y and Z are groups represented by the above formula (3),
4). Furthermore, any one of 1 to 3 benzodithiophenequinone polymers containing repeating units derived from styrene,
5. The benzodithiophenequinone polymer according to any one of 1 to 4, having a weight average molecular weight of 1,000 to 1,000,000 by gel permeation chromatography (polystyrene conversion),
A charge storage material comprising the benzodithiophenequinone polymer of any one of 6.1 to 5,
An electrode active material comprising a charge storage material of 7.6,
An electrode slurry comprising an electrode active material of 8.7 and a solvent,
A thin film containing an electrode active material of 9.7,
A thin film made from 10.8 electrode slurry,
An electrode comprising a thin film of 11.9 or 10;
Batteries comprising 12.11 electrodes are provided.

  The benzodithiophenequinone polymer of the present invention has a benzodithiophenequinone skeleton, has high electrochemical stability because the generated anion radical is stabilized by two thiophene rings, and is useful as a charge storage material. . Furthermore, since the two-electron reduction proceeds to form a stable dianion, when this is used as an electrode active material for a battery, both high stability and high capacity can be achieved.

  In addition, having a polymer structure reduces solubility, and elution into the electrolyte is suppressed, contributing to improvement in cycleability. By having a polymer structure having a charge storage skeleton, it has solubility in N-methyl-2-pyrrolidone (NMP), which is a solvent often used when forming an electrode slurry, and a conductive aid as required And a binder can be mixed with high uniformity, and an electrode having good characteristics can be produced. In addition, highly swellable and dispersible electrodes can be manufactured with high uniformity. In particular, when both X and Y, or Z is a group represented by the above formula (3), the polymerizable functional group has a minimum molecular weight, has an appropriate swelling performance, Since the stack structure is formed, it is possible to achieve both improvement in capacity and high electrochemical stability.

Furthermore, since the benzodithiophenequinone skeleton has a deep HOMO level, it has high oxidation resistance, and can be expected to withstand the battery manufacturing process in the atmosphere. Application to secondary batteries is also possible.
Moreover, by introducing a repeating unit derived from styrene into the benzodithiophenequinone polymer of the present invention, it can be expected that the swelling and dispersibility are improved and the discharge capacity is improved.

  Due to the above effects, by using the benzodithiophenequinone polymer of the present invention as an electrode active material, a battery having high rate characteristics, high capacity, and high cycleability can be produced. The benzodithiophenequinone polymer of the present invention is particularly suitable as an electrode active material for a secondary battery, and particularly suitable as an electrode active material for an air secondary battery. In a general secondary battery, an inorganic material or a carbon material is used as an electrode active material, and either the positive electrode or the negative electrode is replaced with an electrode containing the benzodithiophenequinone polymer of the present invention. It can also be used as an electrode aid.

[Comparative Example 1] Evaluation of charge retention of thin film electrode using polyvinyl anthraquinone 40 mg of carbon powder and 5 mg of polytetrafluoroethylene resin binder dissolved in NMP were added to 5 mg of polyvinyl anthraquinone, and kneaded using an agate mortar. The obtained mixture was applied onto a glassy carbon substrate, and this was heated and vacuum dried at 60 ° C. for 18 hours to obtain a thin film electrode. Polyvinylanthraquinone was synthesized according to Choi, W., Harada, D., Oyaizu, K., Nishide, HJ Am. Chem. Soc., Vol. 133, pp. 19839-43 (2011).
A half cell similar to that of Example 7 was fabricated using the thin film electrode as a working electrode, a platinum electrode as a counter electrode, an Ag / AgCl electrode as a reference electrode, and a 1.0 mol / L sodium hydroxide aqueous solution as an electrolytic solution.
The half battery produced as described above was charged with a constant current of 1.0 mA until the voltage was -1.3V. Then, after leaving for a certain period of time in the atmosphere, discharging was performed at 1.0 mA. As a result, the ratio between the charge capacity and the discharge capacity (discharge capacity / charge capacity) decreased to 0.38% in the standing time after 10 minutes. The measurement results of the standing time and the charge / discharge ratio are shown in FIG. Thereby, it was confirmed that the benzodithiophenequinone polymer of this invention has a high electric charge retention ability compared with polyvinyl anthraquinone.

[Example 10] Characteristic evaluation of air battery coin cell using thin film electrode of polymer (10) 5 mg of polymer (10) synthesized in Example 1, 5 mg of polytetrafluoroethylene resin binder dissolved in 40 mg of carbon powder and NMP And kneaded using a ball mill. A mixture obtained by kneading at 50 Hz for 15 minutes was applied to a disk electrode, and this was heated and vacuum dried at 60 ° C. for 18 hours to obtain a thin film electrode.
Next, using the thin film electrode, a coin battery shown in FIG. 12 was produced according to the following procedure. First, the thin film electrode 23 is placed on the current collector 24 placed in the negative electrode case 26, and the separator 22 having a thickness of 25 μm made of cell guard impregnated with a 1.0 mol / L sodium hydroxide aqueous solution is used as the thin film electrode. 23 was installed above. Thereafter, a stainless steel weight is laminated on the separator 22, and further an oxygen reduction catalyst 21 is laminated. Then, a 1.0 mol / L sodium hydroxide aqueous solution is injected into the internal space as the electrolytic solution 25, and then a metal is placed on the oxygen reduction catalyst. The negative electrode case 26 is joined to the positive electrode case 27 in a state where a spring is placed and a gasket is arranged at the periphery, and thereby an open type having the oxygen reduction catalyst 21 as a positive electrode active material and the thin film electrode 23 as a negative electrode active material. A coin battery 2 was prepared.
Using the produced coin battery as the working electrode, the thin film electrode side and the oxygen reduction catalyst side as the counter electrode were charged at a constant current of 500 μA until the voltage became −1.1 V, and then discharged at 500 μA. As a result, it became almost constant for 80 seconds near the voltage of −0.70 V, and then rapidly decreased, and the discharge capacity became 145 mAh / g. This confirmed that the polymer of Example 1 was operating as a charge storage material. When the voltage dropped to 0V, charging was performed again, and charging / discharging was repeated 200 times in the range of 0 to -1.1V. FIG. 13 shows the measurement result of the potential difference from the reference electrode when the charge / discharge amount is changed. In addition, FIG. 14 shows the cycle characteristics when charging / discharging.
