摘要:
A liquid electrolyte for electrical storage devices, comprises an ionic liquid having general formula (1) below and a melting point of up to 50°C
wherein R 1 to R 4 are each independently an alkyl of 1 to 5 carbons or an alkoxyalkyl of the formula R'-O-(CH 2 ) n -, R' being methyl or ethyl and the letter n being an integer from 1 to 4, and any two from among R 1 , R 2 , R 3 and R 4 may together form a ring, with the proviso that at least one of groups R 1 to R 4 is an alkoxyalkyl of the above formula; and Y is a monovalent anion. It may also include a nonaqueous organic solvent and/or an ion conductive salt.

An electric double layer capacitor with shorter electrodes that can secure insulation within a container is provided. The electric double layer capacitor 30 of the present invention includes: a stack 15 including a plurality of thin positive electrode plates and thin negative electrode plates; an insulating pouch 31 storing the stack 15; a positive lead plate 11A in which lead terminals of the positive electrode plates are collected; a negative lead plate 12A in which lead terminals of the negative electrode plates are collected; a container 28 storing the pouch 31 in which the stack is stored; a sealing cap 21 sealing an opening of the container; electrode terminals 23 and 24 passing through the sealing cap 21 and fixed; and an insulating film 26 attached to the container 28 of the sealing cap 21. The electrode terminals 23 and 24 and the lead plates are connected, the insulating film 26 is adhered to the pouch 31 in a fluid-tight and air-tight state, the pouch 31 is stored in the container 28, and the opening of the container is sealed with the sealing cap 21.
摘要:
A fabric which desirably has antimicrobial and/or dustproof properties includes a textile material layer which is composed of microfibers with an average fiber diameter of from 1 to 100 µm and contains an inorganic porous substance, and a nanofiber nonwoven fabric layer which is laminated on the textile material layer and has an average fiber diameter of at least 1 nm but less than 1,000 nm. Hygienic products such as masks obtained using the fabric efficiently block microbes such as viruses, and inactivate or destroy the captured microbes.
