Definitions
- the present invention relates to a capacitor, and more particularly to an electric double layer capacitor using porous carbon as an electrode material.
- Devices that store electrical energy include secondary batteries that store electrical energy through chemical reactions at the electrodes and capacitors that store electrical energy through physical adsorption of electrolyte ions onto the electrodes.
- the capacitor since the capacitor has a configuration in which ionic molecules store electric charge, the deterioration due to charging and discharging is small, and excellent cycle characteristics are exhibited. For this reason, it is used for various electric devices.
- Patent Document 1 Here, with the recent development of electrical equipment, there is a demand for increasing the capacity of capacitors, and many proposals relating to increasing the capacity have been made (for example, see Patent Document 1 below). However, it is not sufficient to simply increase the capacity in order to further improve the characteristics of the capacitor and to make it more versatile. In addition, although there are papers on capacitors that describe the board plot showing the relationship between the phase angle and the frequency (see Non-Patent Documents 1 and 2 below), this document is sufficient for the electrochemical characteristics of the capacitor. It is the actual situation that is not considered.
- Non-Patent Documents 1 and 2 the capacitance component is analyzed, but the frequency response speed of the capacitor is not analyzed. Therefore, when the present inventor read from the board plots described in Non-Patent Documents 1 and 2, the frequency response speed of the capacitor was about 0.05 to 0.35 Hz. However, such a value has a problem that the frequency response speed is extremely low and charging and discharging cannot be performed at high speed.
- an object of the present invention is to provide a capacitor that has a high frequency response speed and can be charged and discharged at high speed.
- the capacitor of the present invention comprises a polarizable electrode containing a carbon material and an electrolytic solution, and the frequency response speed when 40% by mass of sulfuric acid is used as the electrolytic solution is 0. .. 7 Hz or more. If the frequency response speed is 0.7 Hz or more, the adsorption / desorption of ions on the surface of the carbon material becomes rapid, so that current can be taken out quickly during discharge, while charging can be completed quickly during charging. Therefore, charging / discharging at high speed becomes possible.
- the electrolytic solution of the present invention is not limited to sulfuric acid according to the description. That is, the case where 40% by mass of sulfuric acid is used as the electrolytic solution is because it is necessary to clarify which electrolytic solution is used because the frequency response speed varies depending on the type of electrolytic solution. It is not described from the intention of limiting the type of electrolytic solution to sulfuric acid.
- porous carbon having a pore and a carbonaceous wall constituting the outer periphery of the pore, the pore is an open pore, and the pore portion is continuous is used. It is desirable. As described above, if the pores are open pores and the pore portions are continuous (in terms of the shape of the carbonaceous wall, the carbonaceous wall may have a three-dimensional network structure). For example, since the electrolyte solution can be smoothly diffused into the carbon material, ions can be adsorbed and desorbed quickly. In the present specification, those having a pore diameter of 2 nm or more are sometimes referred to as mesopores, and those having a pore diameter of less than 2 nm are sometimes referred to as micropores.
- the pores are pores that form a three-dimensional network structure. For example, pores (mesopores) that are substantially reflected on the size of the template material generated in the trace of the template eluted with an acid solution.
- the pores (micropores) generated in the carbon wall from the wall surface of the pores are not included. Further, the pores in this specification do not include micropores unless otherwise specified.
- the diameter of the pore is desirably 2 nm or more and 150 nm or less. This is because when the pore diameter is less than 2 nm, the electrolyte solution may not be smoothly diffused into the carbon material, whereas when the pore diameter exceeds 150 nm, the shape of the carbonaceous wall cannot be maintained.
- the pore volume is desirably 0.2 ml / g or more. This is because it is difficult to secure a specific surface area when the pore volume is less than 0.2 ml / g.
- the pore volume is desirably 3.0 ml / g or less. This is because the carbonaceous wall needs to maintain a three-dimensional network structure.
- the specific surface area of the porous carbon is desirably 200 m 2 / g or more.
- the upper limit of the specific surface area is desirably 2500 m 2 / g or less.
- the specific surface area exceeds 2500 m 2 / g, the shape of the carbonaceous wall may not be maintained, and the pores may not be sufficiently formed.
- FIG. 1 It is a figure which shows the manufacturing process of this invention, Comprising: The figure (a) is explanatory drawing which shows the state which mixed the polyamic acid resin and magnesium oxide, The figure (b) is explanatory drawing which shows the state which heat-processed the mixture, The figure (c) is an explanatory view showing porous carbon.
- TEM transmission electron microscope
- 6 is a graph showing the relationship between frequency and phase angle in cells A1 to A4 and Z.
- Porous carbon as an electrode active material, a conductive additive, and a binder are mixed in a solvent (for example, water) to prepare an electrode slurry, and then this electrode slurry is applied to a current collector. Furthermore, the electrode for evaluation is produced by drying. Next, an electric double layer capacitor can be produced using this evaluation electrode as the positive electrode material, using, for example, a platinum plate as the counter electrode (negative electrode), and using, for example, an aqueous sulfuric acid solution as the electrolyte.
- a solvent for example, water
- the porous carbon used for the electrode active material of the present invention can be produced as follows. First, a flowable material containing an organic resin and template particles made of an alkaline earth metal compound such as an alkaline earth metal oxide, hydroxide, carbonate, or organic acid salt are wet-mixed or dry-mixed to obtain a mixture. Make it. Next, this mixture is carbonized at a temperature of, for example, 500 ° C. or higher in a non-oxidizing atmosphere or a reduced pressure atmosphere. Finally, the template particles are removed by washing, and thereby porous carbon can be produced. The porous carbon produced in this way has a large number of pores having substantially the same size.
- an alkaline earth metal compound such as an alkaline earth metal oxide, hydroxide, carbonate, or organic acid salt
- the pore diameter, the pore distribution of the porous carbon, and the thickness of the carbonaceous wall can be adjusted by changing the diameter of the template particles and the type of the organic resin. Accordingly, by appropriately selecting the diameter of the template particles and the type of the organic resin, it is possible to produce porous carbon having a more uniform pore diameter and a larger pore capacity.
- a polyimide containing at least one nitrogen or fluorine atom in the unit structure is preferably used as the organic resin.
- the polyimide can be obtained by polycondensation of an acid component and a diamine component. However, in this case, it is necessary that one or both of the acid component and the diamine component contain one or more nitrogen atoms or fluorine atoms.
- a polyamic acid film which is a polyimide precursor is formed, and the solvent is removed by heating to obtain a polyamic acid film.
- a polyimide can be manufactured by thermally imidating the obtained polyamic acid film at 200 ° C. or higher.
- diamine examples include 2,2-bis (4-aminophenyl) hexafluoropropane [2,2-Bis (4-aminophenyl) hexafluoropropane], 2,2-bis (trifluoromethyl) -benzidine [2,2 ′.
- the acid component includes 4,4-hexafluoroisopropylidenediphthalic anhydride (6FDA) containing a fluorine atom and 3,4,3 ′, 4′-biphenyltetracarboxylic dianhydride containing no fluorine atom.
- 6FDA 4,4-hexafluoroisopropylidenediphthalic anhydride
- BPDA 4,4-hexafluoroisopropylidenediphthalic anhydride
- PMDA pyromellitic dianhydride
- the organic solvent used as a solvent for the polyimide precursor include N-methyl-2-pyrrolidone and dimethylformamide.
- the imidization method is shown in a known method (for example, see “New Polymer Experimental Science” edited by the Society of Polymer Science, Kyoritsu Shuppan, March 28, 1996, Volume 3, Synthesis and Reaction of Polymers (2), page 158). Thus, either heating or chemical imidization may be followed, and the present invention is not affected by this imidization method.
- a resin having a carbonization yield of 40% by mass or more and 85% by mass or less such as a phenol resin or a petroleum tar pitch
- the carbonization yield is 4% by mass or more and 40% by mass.
- organic resins can be sufficiently used.
- the diameters of the template particles are preferably substantially the same. If the diameters of the template particles are substantially the same, the template particles are uniformly dispersed in the matrix (in the fired product), so that the variation in the spacing between the template particles is reduced. Therefore, the carbonaceous wall has a three-dimensional network structure in which the thickness is almost uniform, and a continuous hole of the same size is formed.
- the alkaline earth metal compound is used as the template particle because the alkaline earth metal compound can be removed with a weak acid or hot water (that is, the template particle can be removed without using a strong acid). This is because it is possible to suppress changes in the properties of the porous carbon itself in the step of removing.
- the use of a weak acid has the advantage that the removal speed is increased, while the use of hot water has the advantage that the disadvantage that the acid remains and becomes an impurity can be prevented.
- the eluted oxide solution can be used again as a raw material, and the production cost of porous carbon can be reduced.
- the carbonization of the mixture is preferably performed at a temperature of 500 ° C. or higher and 1500 ° C. or lower in a non-oxidizing atmosphere or a reduced pressure atmosphere. Since the resin with a high carbon yield is a polymer, the carbonization may be insufficient at less than 500 ° C. and the pores may not be sufficiently developed. On the other hand, the shrinkage is large at 1500 ° C. or more, and the oxide is sintered and coarse. This is because the pore size is reduced and the specific surface area is reduced.
- the non-oxidizing atmosphere is an argon atmosphere or a nitrogen atmosphere
- the reduced pressure atmosphere is an atmosphere of 133 Pa (1 torr) or less.
- the bulk density of the porous carbon is preferably 0.1 g / cc or more and 1.0 g / cc or less.

Specifically, after 0.3 g of porous carbon and 0.0375 g of KB are mixed, a mixture is obtained by adding a certain amount of distilled water (2.5 ml in the standard product) and mixing. Then, 0.0375 g of BM-400 was added to this mixture and kneaded quickly to prepare an electrode slurry.

- the frequency response speed of the capacitor Z is 0.37 Hz, which is low, whereas the frequency response speed of the capacitors A1 to A4 is 0. It is recognized that it is 80 to 1.15 Hz and is high. Therefore, it can be seen that charging of capacitors A1 to A4 is completed more quickly than capacitor Z.
- the transition frequency of the capacitor Z is 100 Hz, which is low, whereas the frequency response speed of the capacitors A1 to A4 is 200 to 300 Hz, which is high. Therefore, it can be seen that the capacitors A1 to A4 have a higher diffusion rate of the electrolyte into the pores formed in the electrodes than the capacitor Z.
- the capacitor Z has a specific surface area larger than those of the capacitors A1 to A4, the capacitor Z is present only to the extent that mesopores cannot be calculated. As a result, the mesopore capacity is remarkably reduced. Therefore, the capacitor Z has a smaller mesopore capacity than the capacitors A1 to A4, so that the time constant is doubled even when the same electrolyte is used.
- the present invention can be used as an electrode material of a capacitor.

Abstract
Description
しかしながら、キャパシタの更なる特性向上や多用途化を図るには、単に高容量化するだけでは不十分である。尚、キャパシタに関する論文で、位相角と周波数との関係を示すボードプロットが記載されているものは存在するが(下記非特許文献1、2参照)、当該文献ではキャパシタの電気化学特性について、十分に考察されていないのが実情である。
周波数応答速度が0.7Hz以上であれば、炭素材料の表面でのイオンの吸脱着が迅速になるので、放電時には素早く電流を取り出すことができる一方、充電時には素早く充電を完了することができる。したがって、高速での充放電が可能になる。
上記構成の如く、細孔は開気孔で、気孔部分が連続するような構成となっていれば(炭素質壁の形状という点から表すと、炭素質壁が3次元網目構造を成していれば)、炭素材料内への電解液の拡散が円滑に行われるので、イオンの吸脱着が迅速に行われる。
尚、本明細書においては、細孔の径が2nm以上のものをメソ孔と称することがあり、細孔の径が2nm未満のものをミクロ孔と称することがある。
また、上記細孔とは、3次元網目構造を形成する細孔を示し、例えば鋳型を酸溶液で溶出させた跡に生じた、鋳型材料の大きさがほぼ反映された細孔(メソ孔)を示すものであり、当該細孔の壁面から炭素壁内に生じた細孔(ミクロ孔)は含まれない。更に、本明細書における細孔とは、特に断り書きがある場合を除き、ミクロ孔は含まれない。
細孔径が2nm未満になると、炭素材料内への電解液の拡散が円滑に行われなくなることがある一方、細孔径が150nmを超えると、炭素質壁の形状が保てなくなるからである。
細孔の容量が0.2ml/g未満であると、比表面積を確保することが困難となるからである。尚、細孔の容量は3.0ml/g以下であることが望ましい。炭素質壁が3次元網目構造を保持する必要があるからである。
比表面積が200m2/g未満であると、三次元網目構造を形成し難いという問題があり、気孔の形成量が不十分で、炭素材料内への電解液の拡散が悪くなることがある。尚、比表面積の上限は2500m2/g以下であることが望ましい。比表面積が2500m2/gを超えると、炭素質壁の形状が保てなくなることがあり、細孔を十分形成できない可能性がある。
電極活物質としての多孔質炭素と、導電助剤と、結着剤とを、溶媒(例えば、水)中で混合して電極スラリーを作製した後、この電極スラリーを集電体に塗布し、更に、乾燥することにより評価用電極を作製する。次いで、この評価用電極を正電極材料に用い、対電極(負極)として例えば白金板を用い、電解液として例えば硫酸水溶液を用いて、電気二重層キャパシタを作製することができる。
具体的には、ポリイミドの前駆体であるポリアミド酸を成膜し、溶媒を加熱除去することによりポリアミド酸膜を得る。次に、得られたポリアミド酸膜を200℃以上で熱イミド化することによりポリイミドを製造することができる。
また、ポリイミド前駆体の溶媒として用いる有機溶媒は、N-メチル-2-ピロリドン、ジメチルホルムアミド等が挙げられる。
〔多孔質炭素の作製〕
先ず、図1(a)に示すように、炭素前駆体として有機酸塩n水和物(具体的にはクエン酸マグネシウム9水和物のクエン酸部分)1と、鋳型前駆体としてクエン酸マグネシウム9水和物(和光純薬工業株式会社製の化学用試薬)中のマグネシウム部分を2として出発物質とした。次に、図1(b)に示すように、この出発物質を窒素雰囲気中800℃で1時間熱処理して、有機酸塩を熱分解させることにより炭素質壁3を備えた焼成物を得た。次いで、図1(c)に示すように、得られた焼成物を1mol/lの割合で添加された硫酸水溶液で洗浄して、マグネシウム化合物を略完全に溶出させることにより多数の細孔4を有する多孔質炭素5を得た。尚、図1においては、多孔質炭素5を平面的(模式的)に表しているので、細孔4同士が連通していない(気孔部分が連続していない)ように見えるが、実際には、図2に示すように、細孔は開気孔であって、気孔部分が連続するような構成となっている。
電極活物質としての上記多孔質炭素と、導電助剤としてのケッチェンブラック(KB)と、結着剤としてのゴム系バインダー(日本ゼオン株式会社製、BM-400)とを、質量比が80:10:10となるように混合して電極スラリーを調製した。具体的には、0.3gの多孔質炭素と、0.0375gのKBとを混合し、一定量の蒸留水(標準品においては2.5ml)を加えて混合することにより混合物を得た後、この混合物にBM-400を0.0375g加えて、速やかに混練することで、電極スラリーを調製した。
この後、電解夜の調製とセルの組立とを行った。
水系キャパシタの電解夜には、40質量%の硫酸水溶液を用いた。この際、電解液中の溶存酸素の存在は、陽分極させた際、酸素発生反応に対する電流量が重畳する。この結果、精度の良いキャパシタ容量を見積もる妨げになる。そこで、40質量%の硫酸水溶液を40ml採取し、1時間アルゴンバブリングを行うことにより電解液を調製した。尚、バブリングに用いる気体としてはアルゴンに限定するものではなく、窒素を用いても良い。但し、酸素除去能のより高いアルゴンを用いるのが好ましい。
セルとしては三極式セルを用いた。具体的には、以下のようにして作製した。ガラス容器内に、作用電極と、この作用電極を挟む2枚の対極と、参照電極とを配置した。上記作用電極としては上述の評価用電極を用い、上記対極としては150メッシュの白金網を用い、上記参照電極としてはAg/AgCl電極を用いた。次に、これを、真空ポンプを用いて0.02MPaまで真空引きした後、上記バブリング処理後の電解液をセル内に導入し、更に1時間以上真空引きを続けることにより、電極の脱気を完了させた。これにより三極式セルを完成させた。
このようにして作製したセルを、以下、セルA1と称する。
出発物質をクエン酸マグネシウムとし、且つ、熱処理温度を1000℃として多孔質炭素を作製した以外は、上記実施例1と同様にしてセルを作製した。
このようにして作製したセルを、以下、セルA2と称する。
出発物質をクエン酸マグネシウムとして多孔質炭素を作製した以外は、上記実施例1と同様にしてセルを作製した。
このようにして作製したセルを、以下、セルA3と称する。
熱処理温度を1000℃として多孔質炭素を作製した以外は、上記実施例1と同様にしてセルを作製した。
このようにして作製したセルを、以下、セルA4と称する。
このようにして作製したセルを、以下、セルZと称する。
上記セルA1~A4、Zに用いた炭素材料について、比表面積(BET比表面積)と、メソ孔容量と、メソ孔径とを求めたので、その結果を表1に示す。尚、上記比表面積は、吸着等温線の結果からBET法を用いて算出した。また、メソ孔容量はBET法から求め、メソ孔径はBJH(Berret-Joyner-Halenda)法で求めた。
また、キャパシタZでは、遷移周波数が100Hzであって、低くなっているのに対して、キャパシタA1~A4では、周波数応答速度が200~300Hzであって、高くなっていることが認められる。したがって、キャパシタA1~A4はキャパシタZに比較して、電極に形成された細孔内への電解液の拡散速度が高くなることがわかる。
更に、キャパシタZはキャパシタA1~A4に比べて比表面積が大きいものの、メソ孔が算出できない程度しか存在しておらず、その結果、メソ孔容量も格段に小さくなっている。したがって、キャパシタZはキャパシタA1~A4と比較して、メソ孔容量が小さいことにより、同じ電解液を用いた場合においても時定数が2倍劣る。
