Abstract
The utility model discloses a lithium ion battery structure of a two-terminal output electrode. Battery cores are arranged between an upper battery shell and a lower battery shell. The lithium ion battery structure is characterized in that a first contact and a second contact which are not connected with each other are embedded at the different end faces of the upper battery shell or the lower battery shell during injection molding; a first bonding pad and a second bonding pad are respectively arranged on the positions, adjacent to the first contact and the second contact, on a protection circuit board; the first bonding pad is connected with the first contact through a lead by utilizing a groove of a battery; the second bonding pad is connected with the second contact through a lead by utilizing the groove of the battery. According to the lithium ion battery structure, internal coated copper of the protection board is used as electrode output for connecting different positions of a shell, the battery thickness space is saved, shell injection molding is convenient, battery assembly is convenient, and the shell processing cost is reduced.
Description
Technical field
The utility model relates to lithium ion battery field, in particular, relates to the lithium ion battery structure of a kind of two ends output electrode.
Background technology
Lithium ion battery has the advantages such as voltage is high, specific energy is high, recycle often, memory time is long, not only on portable electric appts as mobile phone, Digital Video and laptop computer are used widely, and be widely used in the big-and-middle-sized electrical equipment aspects such as electric automobile, electric bicycle and electric tool, therefore require more and more higher to the overall dimension of lithium ion battery.Some power supply headspaces are narrow and small, but difference while simultaneously requiring again battery diverse location all to want output electrode to meet battery to use is exported, input state.And cell integrated structure is very compact, shell wall is very thin, between battery case and battery, in the very little situation in space, is very difficult in different battery end-face output electrodes simultaneously.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the casing of lithium ion battery structure of a kind of two ends output electrode is provided.
The technical solution of the utility model:
The lithium ion battery structure of a kind of two ends output electrode; between battery upper casing and battery lower casing, battery is set; it is characterized in that: pre-buried unconnected the first contact and the second wafer each other in the time of the different end face injection moulding of battery upper casing or battery lower casing; position adjacent with the second wafer with the first contact on protective circuit plate arranges respectively the first pad and the second pad; the first pad utilizes the groove of battery to be connected with the first contact by wire, the second pad utilizes the groove of battery to be connected with the second wafer by wire.
The utility model pre-buried unconnected output contact each other when different end face injection moulding on shell, separate between contact like this, can not take inside battery space because interconnecting, connection between contact completes by protective circuit plate, protective circuit plate plays and prevents battery short circuit on the one hand, overcharge, cross and put, overcurrent, the effect of power management, protective circuit plate and two diverse locations are exported the close position of contact and are all designed with pad on the other hand, utilize the groove of battery that the different pads of baffle are connected with the contact on shell by wire, the output of battery is directed on shell contact.In design in the past, the output contact of diverse location is interconnective with nickel strap; protect and connect the battery short circuit that nickel strap causes with nickel strap after avoiding battery to install by insulating paper; but such design nickel strap and insulating tape have taken part battery space, impact assembling effect.The utility model has been saved the space of nickel strap, and maximum utilizes existing space to complete the output of the different end faces of battery.
The utility model has the advantages that: utilize the copper that covers of baffle inside to export as the electrode of connected with outer casing diverse location, save cell thickness space, facilitate shell injection moulding, battery is easy to assembly, and shell processing cost reduces.
Brief description of the drawings
Fig. 1 is the lithium ion battery structure schematic diagram with two ends output electrode;
In figure: 1. the first contact 2. lower casing 3. battery core 4. upper casings
5. protective circuit plate 6. wire 7. the second wafers.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, there is the cylinder type lithium battery of multi-protective function, as we can see from the figure, of the present utility modelly formed by two aggregation battery cores 3, protective circuit plate 5, battery upper casing 4, battery lower casing 2, the first contact 1, the second wafer 7 and wire 6.Between the like-identified pad of baffle, cover copper by inside and connect, utilize the groove cabling of battery that the output on baffle is directed on the contact of battery case by wire, saved the thickness space of battery.
The utility model reduces battery wall thickness, utilizes protective circuit plate by the contact output polarity of diverse location.
The utility model utilizes the groove between forward position and the connection in series-parallel battery of polymer battery core to connect output.
The utility model is exported the contact polarity of different shell diverse locations by protective circuit plate.
