Abstract
The utility model relates to a battery with double cells, which comprises coiled core bodies, aluminum plastic films and electrolyte. The aluminum plastic films are used for coating the coiled core bodies, the electrolyte is inserted into the aluminum plastic films, each coiled core body is formed by coiling an anode, a diaphragm and a cathode, the two coiled core bodies which are in parallel connection are arranged inside the aluminum plastic films, and the anodes and the cathodes of the two coiled core bodies are coincident respectively. The two coiled core bodies are parallelly connected at lugs to form the battery, and the anode and the cathode of each coiled core body are respectively provided with two lugs via inner parallel connection, thereby greatly reducing inner resistance of the battery. On conditions of utilizing the same materials, discharge multiplying factor of the battery manufactured via a common manufacturing method is 15C, and multiplying factor property of the battery with double cells can achieve 25C.
Description
Technical field
The utility model relates to a kind of two electric core battery.
Background technology
Advantages such as lithium ion battery has voltage height, specific energy height, has extended cycle life, memory time is long, not only on portable electric appts, be used widely as mobile phone, Digital Video and laptop computer, and be widely used in big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, therefore more and more higher to the performance requirement of lithium ion battery.
Traditional liquid flexible packing battery is made and is used single volume core body, finishes with the plastic-aluminum packaging film encapsulation and forms a battery, and its both positive and negative polarity respectively has only a lug; Yet for the electrokinetic cell of high-multiplying power discharge, the surface density of positive/negative plate is less, be made into a volume during core body both positive and negative polarity sector-meeting very long, can influence the heavy-current discharge effect like this.
Summary of the invention
The technical problems to be solved in the utility model provides the high two electric core battery of a kind of battery discharge multiplying power.The utility model is achieved through the following technical solutions:
A kind of two electric core batteries of the present utility model, comprise the volume core body, and be used to coat the aluminum plastic film of volume core body, and the electrolyte in the injection aluminum plastic film, described volume core body is reeled and is formed by positive pole, barrier film, negative pole, be provided with the volume core body of two parallel connections in aluminum plastic film, the positive pole of described two volume core bodys overlaps, and negative pole overlaps.
As preferably, described positive pole comprises positive plate and positive pole ear, and described negative pole comprises negative plate and negative lug.
As preferably, the positive pole ear of described volume core body is an aluminium, and negative lug is a nickel.
Two electric core battery of the present utility model owing to use two volume core bodys, is combined into a battery by the parallel connection of lug place, makes both positive and negative polarity that two lugs respectively be arranged by inner parallel connection, has greatly reduced the internal resistance of battery.Use under the situation of same material, the battery discharge multiplying power that normal fabrication method is made is 15C, and two electric core battery high rate performances can reach 25C.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the exploded view of the two electric core batteries of the utility model;
Fig. 2 is the constitutional diagram of the two electric core batteries of the utility model;
Fig. 3 is the exploded view of volume core body in the two electric core batteries of the utility model;
Fig. 4 is the stereogram that the two electric core batteries of the utility model add aluminum plastic film.
Embodiment
As shown in Figures 1 to 4, a kind of two electric core batteries of the present utility model, comprise volume core body 1, and be used to coat the aluminum plastic film 2 of volume core body 1, and the electrolyte (not shown) in the injection aluminum plastic film 2, described volume core body 1 is reeled and is formed by positive pole 10, barrier film 11, negative pole 12, is provided with the volume core body 1 of two parallel connections in aluminum plastic film 2, the positive pole 10 of described two volume core bodys 1 overlaps, and negative pole 12 overlaps.Described anodal 10 comprise positive plate 101 and positive pole ear 102, and described negative pole 12 comprises negative plate 121 and negative lug 122.Owing to use two volume core bodys 1, be combined into a battery by the parallel connection of lug place, make both positive and negative polarity that two lugs respectively be arranged by inner parallel connection, greatly reduced the internal resistance of battery.In the present embodiment, the positive pole ear of described volume core body is an aluminium, and negative lug is a nickel.
Two electric core battery of the present utility model uses two volume core bodys, is combined into a battery by the parallel connection of lug place, wraps one deck plastic-aluminum packaging film in the volume core body outside of two parallel connections again, and electrolyte on the notes is with promptly becoming two electric core batteries after certain current activation.Make both positive and negative polarity that two lugs respectively be arranged by inner parallel connection, greatly reduced the internal resistance of battery.Use under the situation of same material, the battery discharge multiplying power that normal fabrication method is made is 15C, and two electric core battery high rate performances can reach 25C.
The foregoing description; it is an example of the present utility model; be not to be used for limiting enforcement of the present utility model and interest field, all or technical schemes of being equal to identical with the described content of the utility model claim all should be included in the utility model protection range.
