Definitions
- the present invention relates to a quaternary ammonium salt, an electrolyte, an electrolytic solution, and an electrochemical device. Specifically, the present invention relates to a functional material that has high solubility in an organic solvent and can be used as an electrolyte with high withstand voltage and high electrical conductivity. '' Background technology
- organic electrolytes are used more frequently than aqueous ones.
- the organic electrolyte include an alkali metal salt or solid ammonium salt dissolved in an organic solvent such as propylene carbonate.
- the former is an electrolyte for a lithium ion battery, and the latter is an electrolyte for an electric double layer capacitor. It is used as a liquid.
- Organic electrolytes have poor electrical conductivity compared to aqueous systems, and many studies on organic solvents and electrolytes have been conducted to improve electrical conductivity.
- the electrical conductivity of the electrolyte changes with the electrolyte concentration.
- Increasing the concentration of ions in the electrolyte with increasing concentration increases the electrical conductivity, but eventually reaches a maximum.
- the electrical conductivity reaches the maximum point and begins to decrease.
- the interaction between the solvent ions and ions increases, making it difficult for the electrolyte to dissociate. It is thought that the viscosity of the liquid increases. As the electrolyte concentration increases further, it cannot dissociate any more and the electrolyte concentration saturates.
- tetraethylammonium trifluorobore and triethylmethylammonium fluorbore have been used as electrolytes, but these electrolytes are relatively soluble in high-dielectric-constant solvents.
- crystals are precipitated at a higher concentration or at a low temperature.
- it was almost insoluble in low-dielectric constant solvents and could not be used as an electrolyte.
- propylene carbonate, ethylene carbonate, aptyrolactone, or the like is used as a solvent in a high voltage requirement, even if the electrolyte is converted to a high withstand voltage type, it is governed by the decomposition voltage of the solvent.
- the upper limit of the operating voltage of capacity was about 2.5 V.
- the electrolyte mainly solvent
- the electrolyte is electrochemically decomposed, resulting in undesirable performance such as significant deterioration of performance and gas generation.
- improvement of energy density is required, and improvement of operating voltage is an effective means of improving energy density.
- conventional electrolytic solutions cannot improve the withstand voltage, and electrolytes and solvents with higher withstand voltage have been demanded.
- the electrostatic energy of capacitance is proportional to the square of the withstand voltage, so even a slight improvement in withstand voltage is eagerly desired.
- Chain solvents such as ethylmethyl carbonate are listed as solvents with higher withstand voltage, but these solvents with low dielectric constants include conventional tetraethylammonium mutafluorate and triethylmethylammonium tetrafluoro. Electrolytes such as Roboreto were low in solubility and could not be used as electrolytes. In recent years, a salt having a melting point close to room temperature or a salt having a melting point below room temperature (room temperature molten salt) has been found. Such salts are known to dissolve in organic solvents at a higher concentration than ordinary electrolytes even if they are solid at room temperature. In addition, room temperature molten salt is mixed with a specific organic solvent in any ratio.
- an aliphatic ammonium salt into which an alkoxyalkyl group is introduced is excellent in solubility in a non-aqueous organic solvent, and salt precipitation hardly occurs at low temperatures (see Patent Document 1).
- the room temperature molten salt is evaluated for propylene carbonate, which is a solvent having a low withstand voltage.
- capacitors As described above, it is important to use a solvent with a high withstand voltage in order to improve the energy density of the capacitor.
- increasing the electrical conductivity of the electrolyte is an effective technique.
- One of the major features of capacitors is that they can be charged and discharged with a large current compared to secondary batteries. However, when discharging with a large current, the energy lost by the resistance increases. In extreme terms, most of the energy stored in the capacity is lost due to resistance heat. Therefore, reducing the resistance of the capacitor leads to an increase in the energy that can be used substantially among the energy stored in the capacitor, and increasing the electrical conductivity of the electrolyte is an important ci.
