Lithium Ion Capacitor |
摘要 |
Provided is a lithium ion capacitor that is capable, during internal short circuiting, of suppressing an increase in capacitor temperature and controlling the onset of gasification, smoking and ignition, and of having preferably both low resistance (i.e., high output density) and high cycle characteristics. The lithium ion capacitor comprises an electrode laminated body stored in a casing together with a non-aqueous electrolytic solution containing a lithium ion-containing electrolyte; wherein the electrode laminated body is laminated so that a negative electrode collector having a negative electrode active material comprised of a carbon material, and a positive electrode body having a positive electrode active material face each other through a laminated separator where a polyolefin porous membrane and an insulating porous membrane are laminated; and characterized in that the insulating porous membrane is in contact with the negative electrode body. |

1. A lithium ion capacitor comprising an electrode laminated body stored in a casing together with a non-aqueous electrolytic solution containing a lithium ion-containing electrolyte; wherein
said electrode laminated body is laminated so that a negative electrode body having a negative electrode active material comprised of a carbon material, and a positive electrode body having a positive electrode active material face each other through a laminated separator where a polyolefin porous membrane and an insulating porous membrane are laminated; and characterized in that said insulating porous membrane is in contact with said negative electrode body. |
