The utility model discloses the structure is simplified, low in manufacturing cost, but transships the heavy current, has less connection internal resistance.
Description
Technical Field
The utility model relates to a lithium cell technical field, concretely relates to transition row that is used for lithium cell electrode electricity to connect.
Background
With the development of battery technology, especially lithium ion batteries, battery packs composed of single lithium batteries are used as power supplies, both as power batteries and energy storage batteries, and have been widely used in the fields of electric vehicles, energy storage power stations, and the like. The anode of the single lithium battery is an aluminum sheet, and the cathode of the single lithium battery is a copper sheet. The single lithium batteries need to be connected in series to form a battery pack. The existing lithium battery pack is formed by stacking and connecting more than two single lithium batteries in series, and the connection mode of the aluminum electrode and the copper electrode of the adjacent single lithium batteries is mainly as follows: be equipped with aluminium connector, copper connector at aluminium electrode, copper electrode, aluminium electrode and aluminium connector welded connection, copper electrode and copper connector welded connection, connect aluminium connector, copper connector again, the main defect of this kind of mode lies in: the structure is complicated, the manufacturing cost is high, the internal resistance of the joint is large, and the overload large current is difficult to realize.
Disclosure of Invention
The utility model discloses to prior art's not enough, provide a structure simplification, low in manufacturing cost can transship the heavy current, has less copper aluminium transition row that is used for copper aluminium electrode electricity to connect of connecting the internal resistance.
The utility model discloses a technical goal is realized to following technical scheme.
The utility model provides a copper aluminium transition row for copper aluminium electrode electricity connects which improves and lies in: the copper sheet and the aluminum sheet are horizontally arranged side by side, and the adjacent end parts are overlapped and welded to form the copper sheet and the aluminum sheet.
According to a preferable scheme, the copper sheet and the aluminum sheet are both straight plates, and the close ends of the copper sheet and the aluminum sheet are overlapped and welded to form a step structure.
In a further development of this preferred embodiment, the copper and aluminum foils are bent in the longitudinal direction into a circular arc.
In another preferred scheme, the close end parts of the copper sheet and the aluminum sheet are respectively and longitudinally bent to the same side to form an L shape, and the bent L-shaped outer end faces of the copper sheet and the aluminum sheet are overlapped and welded to be connected.
The preferable scheme is further improved in that the opposite ends of the copper sheet and the aluminum sheet are longitudinally bent into a U shape in the same bending direction of the adjacent ends.
Compared with the prior art, the utility model, following positive effect has:
1. by copper sheet, aluminium foil horizontal flat side by side, close tip overlap, welded connection forms copper aluminium transition row, during the use, copper electrode, the aluminium electrode of adjacent monomer lithium cell respectively with the utility model discloses a copper sheet, aluminium foil welded connection just can be with realizing the connection of adjacent monomer lithium cell copper electrode, aluminium electrode, and like this, the structure is simplified, is showing and is reducing manufacturing cost, but transships the heavy current, is showing and is reducing and connect the internal resistance.
2. Various shapes are arranged, and different use requirements are met.
