The lithium battery pack has high security, is convenient to disassemble and is attractive in appearance.
Description
Technical field
The utility model belongs to the battery technology field, relates in particular to a kind of lithium battery group of novelty.
Background technology
The assembling mode of tradition lithium battery group has several kinds: 1, directly soldering connection between the lug of electric core monomer opposed polarity; 2, the head of electric core monomer adds the PCB connecting plate, and cell polar ear is welded on the connecting plate, and connecting plate is through the Copper Foil conducting, and electric core main part is adhesively fixed with double faced adhesive tape.There is following technological deficiency in the assembling mode of these battery pack:
1, destroy electric core hermetically-sealed construction: lug enclosed slot place is temperature 120-200 ℃ during welding, and about 150 ℃ of lug sealing process temperature, and long-time here high temperature has and damages electric core sealing and cause leakage hidden danger;
2, short circuit ratio is high: long-time (about 60S weld time) high-temperature soldering can cause the barrier film contraction between the electric in-core portion positive/negative plate, causes the positive/negative plate short circuit;
3, reprocess difficulty, after cost is high: can't dismantle after the cell polar ear welding combination, if wherein a slice electricity core then can cause whole Battery pack to scrap unusually;
4, the battery pack profile expands: can cause electric core to expand after battery pack is used for a long time or mal-condition uses down again, traditional approach does not have headspace to cause the battery pack profile to rouse shell or explosion.
Summary of the invention
To above-mentioned technological deficiency, the technical problem that the utility model need solve provide a kind of safe, be convenient to dismantle, the lithium battery group of battery pack good looking appearance.
The technical problem that the utility model need solve realizes through following technical scheme: a kind of lithium battery group; Comprise range upon range of electric core monomer; Electricity core monomer is provided with positive and negative lug, and the positive and negative lug of adjacent electric core monomer is to be staggered to left positive and negative lug row and right positive and negative lug row by opposed polarity; In the positive and negative lug row in the left and right sides, be arranged with conducting metal piece and insulated electro wooden unit between the different positive and negative lugs, conducting metal piece and insulated electro wooden unit are staggered successively being located between the different positive and negative lugs.
Further: in above-mentioned lithium battery group, the positive and negative lug in a described left side lists and also is provided with the positive and negative lug in left side row, conducting metal piece and the insulated electro wooden unit fixing lead screw that runs through of riveting tightly; The positive and negative lug in the described right side lists and also is provided with the positive and negative lug in right side row, conducting metal piece and the insulated electro wooden unit fixing lead screw that runs through of riveting tightly.Also be provided with the rubber blanket that electric core monomer is separated between the described electric core monomer.Described rubber blanket is annular.
Compared with prior art, above-mentioned lithium battery group comprises range upon range of electric core monomer, and electric core monomer is provided with positive and negative lug, and the positive and negative lug of adjacent electric core monomer is to be staggered to left positive and negative lug row and right positive and negative lug row by opposed polarity; In the positive and negative lug row in the left and right sides, be arranged with conducting metal piece and insulated electro wooden unit between the different positive and negative lugs, conducting metal piece and insulated electro wooden unit are staggered successively being located between the different positive and negative lugs.The conducting metal piece is adopted in the conducting of positive and negative lug between the electricity core monomer; Such as aluminium block, copper billet etc.; The insulated electro wooden unit is adopted in insulation between next-door neighbour's the positive and negative lug; Realize coupled in series between the different so electric core monomers, positive and negative lug row, conducting metal piece, insulated electro wooden unit are riveted tightly fixing through lead screw.The main part of electricity core monomer adopts ring-shaped rubber pad to isolate, and reserves about 10% expansion space.So the beneficial effect of the utility model patent is:
1, lithium battery group security performance improves: this mode need not high-temperature soldering, can not cause damage to the sealing and the internal diaphragm of lithium battery group;
2, be convenient to dismounting: battery pack becomes and can electric core monomer all be separated replacing after turning on screw, and simple after sale cost is low, and flexibility is high;
3, lithium battery group good looking appearance:, can not cause lithium battery group profile drum shell after electric core monomer uses and expands and break owing to reserve the expansion space.
