Abstract
A lug and terminal connection structure of a power lithium-ion battery is used to solve the problems that an existing lug and terminal connection structure of the power lithium-ion battery is relativley soft in connection strips, poor in operability, hard to guarantee in uniformity and the like. The lug and terminal connection structure comprises a cover plate provided with an anti-rotating support, and rolled cores. The upper portion of each rolled core is connected with an anode lug and a cathode lug, and an anode terminal and a cathode terminal are arranged on the cover plate. The lug and terminal connection structure is characterized in that a bus board is further arranged on the structure, the bus board is bent to be an upper layer and a lower layer, the upper layer is fixedly connected with the terminals, and the lower layer is connected with the lugs. The lug and terminal connection structure of the power lithium-ion battery is standard in assembling operation, good in uniformity, and high in connection reliability. Meanwhile, due to the fact that the thickness of the bus board is increased, the section area of the bus board is increased accordingly, and the charge and discharge multiplying power of the battery is effectively improved.
Description
Technical field
The utility model relates to lug and the terminal connecting structure of a kind of battery components, particularly power lithium-ion battery, belongs to the battery technology field.
Background technology
Lithium ion battery have specific energy high, have extended cycle life, the characteristics such as environmentally friendly, be a kind of battery system that development potentiality is arranged very much, obtain using more and more widely in a lot of Portable movable electronic products, electric tool, new forms of energy relevant industries.Along with the fast development of lithium-ion electric pool technology, a lot of power lithium-ion batteries that are used for power function have also appearred at present.At present, mid power power lithium-ion battery with the design of many groups of volume core parallel waies, when the lug of many group volume cores is connected with battery output terminal, often adopt many groups tab welding with same polarity on shell wall, many groups tab welding of another polarity on terminal connector, is made the lithium ion battery that housing is an electrode; Perhaps the many groups lug with opposed polarity is welded on respectively on the anode and cathode terminals intercell connector, makes the coiled battery of two-terminal structure.Above two kinds of lugs commonly used and terminal connected mode, owing to needing to connect many groups volume core in parallel, and intercell connector thinner thickness, limited the discharging current of battery, and in the battery assembling process, because volume core lug is more, welding direction is overlapping, intercell connector is softer, poor operability, the consistency of battery are difficult to guarantee.
The utility model content
The utility model is used for solving the defective of above-mentioned prior art and a kind of lug and terminal connecting structure of being convenient to the power lithium-ion battery of assembly operation, high conformity is provided.
The alleged problem of the utility model solves with following technical proposals:
A kind of lug of power lithium-ion battery and terminal connecting structure, it comprises with the cover plate of anti-rotation support and volume core, each is rolled up core top and connects positive and negative lug, cover plate is provided with positive and negative terminal, special feature is: described structure also is provided with bus-bar, the bus-bar bending is for two-layer up and down, and upper strata and terminal are affixed, and lower floor is connected with each lug.
The lug of above-mentioned power lithium-ion battery and terminal connecting structure, described lug is comprised of end face and facade, and end face and facade are mutually orthogonal, described facade top parcel high-temperature insulation adhesive tape, facade and the welding of volume core, described end face and bus-bar weld and bus-bar are coated.
The lug of above-mentioned power lithium-ion battery and terminal connecting structure, described bus-bar upper strata is provided with bolt connecting hole, and bus-bar is connected with pole through clamping screw.
The lug of above-mentioned power lithium-ion battery and terminal connecting structure, the thickness of described bus-bar are 0.5～1.5mm.
The problems such as the utility model is for the lug of existing power lithium-ion battery and the terminal connecting structure intercell connector is softer, poor operability, consistency are difficult to assurance are improved, adopted the lug and strap of moulding, each tab welding is on the volume core, a plurality of volume cores consist of the internal poles group of specific model lithium battery, the positive and negative lug of each volume core upper end links to each other with the both positive and negative polarity bus-bar respectively, by the anti-loosening locking bolt bus-bar is connected with pole in the cover plate again.This syndeton assembly operation standard, high conformity, connection reliability is high.Simultaneously, because the thickness of bus-bar increases, its sectional area increases thereupon, Effective Raise the charge-discharge magnification of battery.
