Description
[technical field]
The present invention relates to lithium polymer battery and capacitor with filling, the electrode slice of discharger, relate in particular to lithium polymer battery and capacitor with filling, the electrode slice of discharger, it forms a plurality of zigzag contact sites on electrode slice, can contact with the pole piece surface point, even have under the state of foreign matter or oxide-film on the pole piece surface of lithium polymer battery and capacitor, also contact resistance can be dropped to minimum, fill, discharge, and side by side be placed in brace table on the 1st powered electrode sheet the 2nd powered electrode sheet, contact with lithium polymer battery with capacity more than 10 amperes and capacitor by the 1st powered electrode sheet and the 2nd powered electrode sheet supporter, make and fill, resistance value minimum during discharge, reduce liberated heat, raising is filled, the efficient of discharge.
[background technology]
The electrode slice of lithium polymer battery in the past and capacitor usefulness charge and discharge device as shown in Figures 1 and 2.
Above-mentioned electrode slice 2 becomes a pair of with 2 and combines with supporter 1, and an electrode slice 2 is used for measuring voltage, and another electrode slice 2 is used to pass through electric current.
In order to contact with pole piece 22 surfaces of lithium polymer battery and capacitor 21, above-mentioned pair of electrodes sheet 2 upper ends form semi-circular contact part 3 respectively.
Promptly, for carrying out charge and discharge, above-mentioned lithium polymer battery and capacitor 21 drop between the semi-circular contact part 3 and insulator 11 of electrode slice 2, above-mentioned insulator 11 and supporter 1 will be connected pole piece 22 on lithium polymer battery and the capacitor 21 and be clipped in the middle and shrink mutually, form the state of pushing down of pole piece 22 as shown in Figure 2.
