Abstract
A power-enhanced lithium manganese battery capacity structure is provided, which comprises a lithium ribbon (1) and a tab (2) pressed into one end of the lithium ribbon (1). The structure is characterized in that an adhesive tape (3) is attached to the other end of the lithium ribbon (1) with the tab (2) from one end. The structure overcomes the shortcoming that the lithium ribbon of the current lithium manganese battery can be consumed firstly, which cuts off the electron transport pathway, and the lithium manganese battery hereby can not reach the designed capacity. With the adoption of the technical proposal of the utility model, the lithium manganese battery capacities of different types are all increased by 10 to 20 percent; what's more, the battery capacity consistency is improved as well.
Description
Technical field
The utility model relates to disposable lithium-manganese cell technical field, and more particularly it is a kind of structure that improves power-type lithium-manganese cell capacity.
Background technology
Present disposable power-type lithium-manganese cell, be cylindrical, square all be to adopt takeup type structure (coiling type power type lithium-manganese cell).Its internal electrical core all is by one deck negative electrode (manganese dioxide), reel behind one deck barrier film and one deck anode (lithium band) superposition and form (seeing Fig. 1, Fig. 2), battery is in the process of using, lithium ion on the anode (lithium band) permeates to negative electrode by the barrier film on two sides, be embedded in the negative electrode, gradually anode (lithium band) will run out of, thereby be fully utilized, and emit maximum capacity.Yet battery often can not be emitted designed heaped capacity in the application of reality, and reason is that anode (lithium band) is not fully utilized.The anode (see figure 3) is in the process of discharge, lithium band 1 is the slow consumption attenuation, when the capacity of emitting reaches the 80-90% left and right sides of design capacity, lithium band 1 is under very thin situation, at the 2-3cm place near lug 2 one ends, the lithium band can run out of earlier, thereby has blocked the path of electron transport, cause other end residue lithium band not to be utilized, and can not reach design capacity.
Summary of the invention
The purpose of this utility model is to provide a kind of structure that improves power-type lithium-manganese cell capacity, and it has solved at the power-type lithium-manganese cell in discharge process, and the problem that the anode lithium band disconnects reaches designed capacity requirement, has improved the consistency of battery.
The purpose of this utility model reaches by following measure: a kind of structure that improves power-type lithium-manganese cell capacity: it comprises lithium band 1, lug 2, lug 2 is pressed into an end of lithium band 1, it is characterized in that having adhesive tape 3 to be affixed to the other end of lithium band 1 from an end of lithium band 1 that lug 2 is arranged.
In technique scheme, described adhesive tape 3 is the other ends that are affixed to lithium band 1 from an end of the lithium band 1 that lug 2 is arranged sideling.
When battery discharge, post the side of fillet adhesive tape and the part that is covered by adhesive tape on the lithium band, will not participate in exoelectrical reaction, just just single face participation reaction of the lithium band of this part so, the speed of consumption has only other partly half.When other lithium band has partly become very thin, even when ruing out of, this lithium band still can slow consumption and is played and transmit electronics and guarantee the not intercepted effect of electron transport path.
A kind of structure that improves power-type lithium-manganese cell capacity of the utility model has following advantage: 1. when battery discharge, post the side of fillet adhesive tape and the part that is covered by adhesive tape on the lithium band, to not participate in exoelectrical reaction, just just single face participation reaction of the lithium band of this part so, the speed of consumption has only other partly half.When other lithium band has partly become very thin, even when ruing out of, this lithium band still can slow consumption and is played and transmit electronics and guarantee the not intercepted effect of electron transport path.2. adhesive tape 3 sticks sideling, if with the parallel subsides of lithium band, electric core is behind coiling, the place of taping can accumulate because of the thickness of adhesive tape, diameter can increase herein.Subsides just are distributed to different places uniformly with the thickness of adhesive tape sideling, thereby have avoided the diameter of certain to increase.

Embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to qualification of the present utility model, simultaneously by illustrating that advantage of the present utility model will become clear more and understands easily.
Consult accompanying drawing as can be known: a kind of structure that improves power-type lithium-manganese cell capacity of the utility model, it comprises lithium band 1, lug 2, adhesive tape 3, and lug 2 is pressed into an end of lithium band 1, and adhesive tape 3 is affixed to the other end of lithium band 1 sideling from the end that lug 2 is arranged.
Prove after testing: after having adopted technical solutions of the utility model, the capacity of different big or small size battery all has the increase of 10-20%, and has improved the consistency of battery capacity.
Claims (2)
