Present embodiment bus 17 and 18 used has been equipped with through hole 17A and 18A and portion of terminal 17B and the 18B that makes the front end of convex electrode 9 expose while being connected with convex electrode 9. Bus 19 and 20 has been equipped with through hole 19A and 20A and portion of terminal 19B and the 20B that while being connected with plane-shape electrode 11, plane-shape electrode 11 is partly exposed.In present embodiment, the electrode (9,11) that bus 17～20 is connected to electrochemical cell 13 by welding or resistance welded is upper, forms in advance cell assembly 3.
One end in the direction that is positioned at lithium-ion capacitor 13A～13D extension of the first support 5 and cell assembly 3 is chimeric.In addition, the other end in the direction that is positioned at lithium-ion capacitor 13A～13D extension of the second support and cell assembly 3 is chimeric.In present embodiment, as the first support 5 and the second support 7, use the identical shaped support shown in Fig. 3 (A) to (F).The second support 7 is chimeric with the posture with respect to the first support 5 rotations in 90 ° and cell assembly 3.
The structure of support 5 is described below with reference to Fig. 3.The support 5 using in present embodiment is shaped integratedly by dielectric resin material, has bottom wall portion 21 and surrounding wall portion 22.Bottom wall portion 21 has the profile of essentially rectangular, relative with one end or the other end of cell assembly 3.In bottom wall portion 21, on its central part, be formed with and insert for the fixing centre bore 23 of the not shown screw with head of the pillar shown in Fig. 1 16.In addition, as shown in Fig. 3 (C), on relative two limit 21A among four limit 21A to 21D of bottom wall portion 21 and 21C, be formed with recess 21E and the 21F of semicircle arcuation, this recess 21E and 21F form in the mode towards centre bore 23 projections, and connect the thickness direction of bottom wall portion 21, and to the direction opening away from centre bore 23.This recess 21E and 21F are for exposing the portion of terminal of bus.In this external bottom wall portion 21, with limit 21A and 21C intersects vertically and imaginary line L1 by centre bore 23 and with limit 21B and 21D intersects vertically and imaginary line L2 by centre bore 23 passes through position on, form respectively four and there is the through hole 24 that can make the diameter that voltage detecting passes through with lead-in wire.Four through holes 24 respectively separate 90 ° of angles and form around centre bore 23 respectively.If extraction voltage is set like this, detect the through hole 24 with lead-in wire,, no matter support 5 is chimeric with which kind of position relationship and cell assembly 3, also can not make voltage detecting go between more longways with lead-in wire, can to outside, draw from any of four through holes 24.Further, four through holes 25 in bottom wall portion 21, have been formed, on imaginary two diagonal in four bights that make it lay respectively at bottom wall portion 21.For the function of this through hole 25, in the back explanation.In addition,, in bottom wall portion 21, on the position of passing through at described imaginary line L2, be formed with two through holes 26.This through hole is installing hole.
From the edge part of bottom wall portion 21, erect and the surrounding wall portion 22 of extending to cell assembly 3 sides consists of four side wall portion 22A～22D that have equal length size and intersect vertically respectively.On the relative 22A of pair of sidewalls portion and 22C, be formed with the 22E of pair of openings portion and the 22F that are communicated with a pair of recess 21E forming in bottom wall portion 21 and 21F.In addition, on side wall portion 22B, be formed with two peristome 22G and 22H.
In support 5, have by bottom wall portion 21 and surrounding wall portion 22 and surround the chimeric chimeric recess 28A～28D that uses in four ends in the end with four lithium-ion capacitor 13A～13D forming.Four ends are chimeric to be had on its bottom with recess 28A～28D and takes in the buffering being configured in compressive state between bus 17～20 and bottom wall portion 21 and take in use recess 30A～30D with the pad of pad 29.With pad 29, the rubber by ring-type forms buffering.If such pad 29 for buffering is set, in two 5 and 7, no matter the configuration direction of four lithium-ion capacitors how, buffering by compression is chimeric with the space between the bottom of recess 28A～28D with a part and the end of pad 29 landfill buses 17～20, cell assembly 3 can be remained between the first support 5 and the second support 7.
Four ends are chimeric chimeric with recess 28A and 28D connection with two ends in recess 28A～28D, to take in the bus 18 of crossing over two lithium- ion capacitor 13A and 13D configuration.And two ends are chimeric with recess 28B and 28C connection, to take in the bus 17 of crossing over two lithium- ion capacitor 13B and 13C configuration.Adopt the result of such structure to be, in support 5, be formed with a divider wall parts 31.
In present embodiment, on the side wall portion 22A of the chimeric surrounding wall portion 22 with recess 28A and 28D in two ends being communicated with in the mode of surrounding with income bus 18, be formed with accordingly a peristome 22E with the chimeric centre position with recess 28A and 28D, two ends, on the side wall portion 22C of the chimeric surrounding wall portion 22 with recess 28B and 28C in two ends being communicated with in the mode of surrounding with income bus 17, be formed with accordingly a peristome 22F with the chimeric centre position with recess 28B and 28C, two ends, further, on side wall portion 22B, be formed with the peristome 22G at two chimeric direction openings of arranging with recess 28A and 28D in end, with the peristome 22H at two chimeric direction openings of arranging with recess 28B and 28C in end.In this example, peristome 22G and 22H, to same direction opening, still, also can form one of them in two peristome 22G and 22H certainly on side wall portion 22D, and two peristome 22G and 22H be opening inversely mutually.If such four peristome 22E～22G are set on support 5 and 7, in the situation that connecting a plurality of columnar lithium ion capacitor with various cloth ray modes such as parallel connection, series connection, connection in series-parallel, by making another support 7 with respect to a support 5 rotation the fixing position relationship of two stands, can realize nearly all cloth ray mode, improve the versatility of support.
