Description
Technical Field
The utility model belongs to the technical field of lithium ion battery, concretely relates to lithium cell is just, negative pole ear and lithium cell.
Background
The utmost point ear of the electric core of the lithium cell among the prior art, just, the negative pole ear need adopt different materials to make usually, positive ear uses the aluminum product usually, the negative pole ear uses the copper product, it is fashionable at the group battery, just, the negative pole ear externally respectively with metal row welded connection, however because just, the negative pole ear has adopted different metal material, the mutual welding degree of difficulty is high between the different metal material, so also be difficult for welding between utmost point ear and the outside metal sheet, adopt the aluminium row the same with positive ear then negative pole ear is difficult for welding, adopt the copper bar the same with the negative pole ear then positive ear is difficult for welding, the welding is unreliable, and the processing cost is high. Chinese patent CN205752354U discloses a lithium battery tab for the welding process of the lithium battery tab is more convenient and simple when the battery is assembled, the processing cost is low including the copper strip substrate, the surface of one end of the copper strip substrate is covered with the aluminum layer, and the lithium battery of the lithium battery tab is still adopted. However, when the lithium battery tab is used for replacing the positive tab, the external metal plate is a copper bar, the cost is high, and when the lithium battery tab is used for replacing the negative tab, the positive tab is made of pure aluminum, and the resistance is large.
Disclosure of Invention
Not enough to above-mentioned prior art, the utility model aims at providing with low costs, the lithium cell that resistance is little just, the negative pole ear and use this lithium cell just, the lithium cell of negative pole ear.
In order to achieve the above object, the utility model provides a following technical scheme: lithium cell is just, negative pole ear, including positive pole ear, negative pole ear, its characterized in that: the anode tab adopts a copper strip base material, the whole surface of one end is coated with an aluminum layer, the surfaces of the front side and the back side of the other end are coated with aluminum layers, the cathode tab adopts a copper strip base material, and the surface of one end is coated with an aluminum layer. Further, the aluminum layers of the negative electrode tab are coated on the front and back side surfaces of one end of the negative electrode tab.
The utility model provides a lithium battery, adopts above-mentioned lithium battery just, negative pole ear as the positive, negative pole ear of lithium battery, the one end setting that the aluminium lamination had been covered on positive ear full surface is inside the lithium battery and with the inside electrode material of lithium battery is connected, and the one end setting that the aluminium lamination had been covered on positive and negative both sides surface is outside the battery, the negative pole ear covers the one end setting that has the aluminium lamination and is outside the battery, and the other end setting is in inside the lithium battery and with the inside electricity of lithium battery
The anode tab and the cathode tab are exposed out of the outer end of the lithium battery and are respectively connected with an aluminum bar in a welding mode.
Compared with the prior art, the utility model discloses following beneficial effect has: the positive electrode lug and the negative electrode lug are both made of copper strip base materials, so that the resistance is small; the outer ends of the exposed lithium batteries are covered with aluminum layers and are welded with the aluminum bars, so that the cost is low, and the welding is easy and reliable.
