摘要:
Electrical storage devices having excellent low-temperature properties can be obtained by using a quaternary salt (or ionic liquid) of general formula (1) below as an electrolyte salt for electrical storage devices or a liquid electrolyte for electrical storage devices. In formula (1), R1 to R4 are each independently an alkyl group of 1 to 5 carbons or an alkoxyalkyl group of the formula R′—O—(CH2)n—, with the proviso that at least one group from among R1 to R4 is the above alkoxyalkyl group.

摘要:
The water present within an ionic liquid that is in a liquid state at 25° C. or an organic solution containing at least one ionic compound is decomposed by bringing electrodes into contact with the ionic liquid or organic solution within an atmosphere having a dew-point temperature not higher than −40° C. or under a reduced pressure of not more than 75 torr, thereby reducing the water content. This process makes it possible to obtain highly dehydrated ionic liquids.

Secondary cells and electrical double-layer capacitors of excellent charge-discharge efficiency, stability and low-temperature properties can be obtained using nonaqueous electrolytes which contain an ionic liquid that has general formula (1) below and is liquid at not higher than 50° C. and an ion-conductive polymer. In formula (1), R1 to R4 are each independently an alkyl group of 1 to 5 carbons or an alkoxyalkyl group of the formula R′—O—(CH2)n—(R′ being methyl or ethyl, and the letter n being an integer from 1 to 4), and any two from among R1, R2, R3 and R4 may together form a ring, with the proviso that at least one of R1 to R4 is an alkoxyalkyl group of the above formula. X is a nitrogen atom or a phosphorus atom, and Y is a monovalent anion.

摘要:
A capacitor system suitable for charging and discharging of a vehicle such as discharging due to starting of an engine, charging by an alternator, and recharging upon braking. The capacitor system can be a vehicle power source having several connected cells in which ion conductive materials are arranged between a pair of electrode structures with large surface area materials and an electric double layer is formed between the large surface area materials in the electrode structure and an electrolyte of the ion conductive materials. Charging and discharging are controlled for state of charge of the capacitor unit with several connected modules to be within a predetermined range. A minimum charge within the predetermined range is sufficient for the engine to start while a maximum charge within the predetermined range is within a rated voltage of the capacitor unit with several connected modules.
摘要:
A polymer gel electrolyte includes an electrolyte solution composed of a plasticizer with at least two carbonate structures on the molecule and an electrolyte salt, in combination with a matrix polymer. Secondary batteries made with the polymer gel electrolyte can operate at a high capacitance and a high current, have a broad service temperature range and a high level of safety, and are thus particularly well-suited for use in such applications as lithium secondary cells and lithium ion secondary cells. Electrical double-layer capacitors made with the polymer gel electrolyte have a high output voltage, a large output current, a broad service temperature range and excellent safety.
