Description
Technical field
The utility model relates to the cylindrical flexible-packed battery structure of a kind of lithium manganese.
Background technology
Existing cylindrical lithium manganese cell is the box hat structure, there is following shortcoming in this structure: 1. the box hat cylindrical battery adopts first customized shell, the method for back plug positive and negative pole material, and it is not tight to cause electric core to contact with housing like this, the space does not make full use of in the battery case, and the capacity of battery is low; 2. it is too much that the metal-back battery size is subjected to the restriction of shell, and weight is big simultaneously.3. the poor stability of complex structure, use.
Summary of the invention
The objective of the invention is to overcome the weak point of above-mentioned existing box hat cylindrical battery, and provide a kind of lithium manganese cylindrical flexible-packed battery structure.
The purpose of this utility model reaches by following measure: the cylindrical flexible-packed battery structure of lithium manganese, it comprises anode ear, negative electrode lug, as the lithium band of negative plate and the positive plate of doing with manganese dioxide, lithium band and positive plate isolate by barrier film and electrolyte and coiled cylindrical, it is characterized in that described anode ear and negative electrode lug lay respectively at columniform two ends, the cylindrical outer layer of aluminum plastic film outsourcing that has.
In technique scheme, between described anode ear and the positive plate insulating cement is arranged, between negative electrode lug and the lithium band insulating cement is arranged.
The utility model flexible package cylinder lithium-manganese cell structure is compared with box hat cylinder lithium-manganese cell has following advantage: (1). and security performance is good: the flexible package cylindrical battery structurally adopts plastic-aluminum flexible packing, be different from the metal shell of box hat cylindrical lithium manganese, in case generation potential safety hazard, the metal shell battery explodes easily, and flexible-packed battery usually at most only can tympanites, blasts, probability on fire is extremely low.(2). the capacity height, volume is little: common box hat cylindrical battery adopts first customized shell, the method of back plug positive and negative pole material, it is not tight to cause electric core to contact with housing like this, the space does not make full use of in the battery case, and flexible-packed battery can utilize the useful space more fully, makes that the capacity of unit volume performance is higher, and can do forr a short time with the capacity situation lower volume.(3). in light weight: as because the huge advantage of sheathing material on weight, to make the box hat battery light about 40% of the equal capacity specifications of flexible-packed battery weight.(4). internal resistance is little, can provide bigger discharging current and the discharge platform of Geng Gao: because the inner basic vacuum state that is of flexible-packed battery, contact between positive pole, barrier film and the negative pole is more tight, effectively reduced the internal resistance of cell, thereby bigger discharging current and the discharge platform of Geng Gao can be provided, satisfy the demand of high power consumption electrical appliance.(5). self discharge is little, and electrical property is more stable: the sheathing material aluminum-plastic composite membrane surface of flexible-packed battery is non-conductive, can effectively avoid because inside battery floats the inside battery micro-short circuit that powder causes, thereby reduce self-discharge rate, and more stable electrical property is provided.(6). the overall dimension flexible design, the exploitation of new model battery is rapid: because the punching out of flexible-packed battery shell is random big, its overall dimension design is very flexible, and it is too much that size is subjected to the influence restriction of shell unlike the metal-back battery, more can satisfy customer personalized demand.

Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute qualification of the present utility model, simultaneously by with the contrast of the structure of existing box hat cylindrical lithium manganese cell, advantage of the present utility model will become clear more and understand easily.
Consult Fig. 8 as can be known: the cylindrical flexible-packed battery structure of the utility model lithium manganese, it comprises anode ear 1, negative electrode lug 2, as the lithium band 3 of negative plate and the positive plate of doing with manganese dioxide 4, lithium band 3 and positive plate 4 isolate by barrier film and electrolyte 5 and coiled cylindrical, described anode ear 1 and negative electrode lug 2 lay respectively at columniform two ends, the cylindrical outer layer of aluminum plastic film 6 outsourcing plastic packagings that have; Between described anode ear 1 and the positive plate 4 insulating cement 7 is arranged, insulating cement 7 (insulating cement has the effect that connects and insulate) is arranged between negative electrode lug 2 and the lithium band 3.
Consult Fig. 9 as can be known: the cylindrical flexible-packed battery structure compared of existing box hat cylindrical lithium manganese cell and the utility model lithium manganese is more complicated, its anode ear 1, negative electrode lug 2 are positioned at the same end of cylindrical lithium manganese cell, and increased positive cover resistance 12, in the lower end of positive cover resistance 12 sealing position 11 is arranged, below box hat cylindrical lithium manganese cell, insulating trip 8 is arranged, blast ring 9 is arranged in the lower end of insulating trip 8.Parts are more, so complex structure.
