Description
Technical field
The utility model relates to a kind of battery.
Background technology
The application of storage battery more and more widely, modern society is also more and more higher to the requirement of indexs such as the performance of storage battery, capacity.Need jumbo battery pack as electric bicycle and electric automobile, such battery pack is connected by a large amount of batteries or is composed in parallel.
The battery case of existing cylindrical battery is generally negative pole, and it is anodal that battery cap is generally.Because it is less that the anodal block of cylindrical battery is used for the contact area of positive electrical connection, when being connected into battery pack, cylindrical battery can only adopt welding manner, and this has limited the assembling mode of cylindrical battery composition battery pack to a certain extent.Be electrically connected the battery pack that is connected into when breaking down by welding, can easily do not detect and change, whole battery group can only be scrapped, therefore caused huge waste single battery.
Generally all design on the block of existing secondary lithium-ion cylindrical battery the explosion-proof valve device is arranged, time block is produced in case battery breaks down, but when explosion-proof valve lost efficacy, battery breaks down afterwards to block a shot and still may produce, and cause the electrolyte leakage, thereby influence other normal battery.
The shell of secondary lithium-ion cylindrical battery generally is the steel of outer nickel plating, coating is worn easily in production and use, thereby cause getting rusty, finally cause the resistance of battery pack and battery positive and negative electrode electrical connections to increase even can't conducting, reduced the electric current output performance of battery or made battery can not export electric energy, influenced the normal use of battery pack, in addition some the time can cause bigger security incident.
The utility model content
The utility model purpose is to provide a kind of be convenient to dismounting and replacing in battery pack, has the higher-security energy, guarantees that battery in use keeps the assembled battery of low internal resistance.
In order to achieve the above object, the utility model provides a kind of assembled battery, and this assembled battery comprises reel electric core, shell, block, and this assembled battery also comprises positive electrode cap, and positive electrode cap is positioned at the block outside and is electrically connected with block.Positive electrode cap comprises insulator cap and the outer cap of cathode metal.
The assembled battery that the utility model provides, positive electrode cap is electrically connected by welding with block, insulator cap is set to keep the insulation of positive electrode cap and shell between outer cap of the cathode metal of positive electrode cap and the battery case.
In order to achieve the above object, the utility model provides a kind of assembled battery, and this assembled battery also comprises the negative pole cap, and the negative pole cap is electrically connected with battery case.
The outer cap whole outer surface of the cathode metal of the assembled battery that the utility model provides may be used to the outside and is electrically connected to be assembled into battery pack, so can adopt for the battery pack of various electric connection mode, for example, in the conductive hole that is inserted into battery frame, the periphery of the outer cap of cathode metal or bottom surface are electrically connected with conductive hole and are assembled into battery pack, dismantle easily when the battery pack of this structure breaks down, and can detect and change single battery.
The assembled battery that the utility model provides, the negative pole cap is electrically connected by welding with battery case, connected mode is fastening reliable, electrical connections is not got rusty by shell to be influenced, the negative pole cap can adopt the copper of outer nickel plating, be electrically connected reliably with battery pack with battery guaranteeing, improved the security performance of battery pack.
The assembled battery that the utility model provides, the negative pole cap is electrically connected by welding with battery case, and electrical connections is not got rusty by shell to be influenced, and can guarantee that battery in use keeps low internal resistance, thereby guarantee the normal use and the fail safe of battery.
Description of drawings
Fig. 1 is the explosive view of the assembled battery that provides of the utility model.
Fig. 2 is the positive electrode cap structural representation of assembled battery of the present utility model.
Fig. 3 be assembled battery of the present utility model insulator cap partly cut open schematic diagram.
Fig. 4 is the negative pole cap schematic diagram of assembled battery of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
As shown in Figure 1 and Figure 2, assembled battery 1 comprises battery 2, positive electrode cap 3 and negative pole cap 4.Positive electrode cap 3 is made up of insulator cap 5 and the outer cap 6 of cathode metal, and negative pole cap 4 is a metallic conductor.
The outer cap 6 of cathode metal and block 7 are electrically connected by spot welding, and the outer cap 6 of cathode metal utilizes insulator cap 5 and shell 8 insulation, and step 9 is arranged on the insulator cap 5, and step 9 is used to guarantee that outer cap 6 of cathode metal and shell 8 insulate.Battery 1 was electrically connected with the positive pole of battery pack when the outer cap 6 of cathode metal was used for that assembled battery 1 is assembled into battery pack.The outer contact area of the outer cap 6 of cathode metal is big, is applicable to the assembling of the large-capacity battery pack of various assembling modes.For example, the outer cap 6 of cathode metal is inserted in the conductive hole of battery frame, the periphery of the outer cap 6 of cathode metal or bottom surface are electrically connected with conductive hole and are assembled into battery pack.Dismantle easily when the battery pack of this structure breaks down, and can detect and change single battery.
Wherein the through hole 10 of the outer cap 6 of cathode metal is used for exhaust.
As shown in Figure 3, there are the card rank 11 that are connected in shell 8 slot rollings inboard of insulator cap 5, and these card rank 11 are used for the stable assembling of positive electrode cap 3 and battery 2.When the explosion-proof valve of battery 2 lost efficacy, battery 2 broke down, then block a shot 7 can be subjected to insulator cap 5 card rank 11 resistance and can not produce, thereby guaranteed the stability and the fail safe of battery pack.
The outer cap 6 of cathode metal can become with the copper of outer nickel plating.Insulator cap 5 can adopt PTFE (polytetrafluoroethylene) material and other proper polymer material of high temperature high voltage resistant.
Be illustrated in figure 4 as the negative pole cap 4 of assembled battery 1, negative pole cap 4 and battery case 8 are electrically connected by spot welding.When battery case 8 got rusty, negative pole cap 4 can guarantee to be electrically connected with the spot welding electric connection mode of shell 8 to be stablized, and prevents to be electrically connected the resistance increase, thereby has guaranteed the security performance and the serviceability of battery pack.
The above only is embodiment of the present utility model; and unrestricted practical range of the present utility model; all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included within the protection range of the utility model patent application.
