Abstract
The utility model discloses a Li-ion battery cover plate comprising a plate body, wherein, the upper side and lower side of the plate body are provided with a sealing pad separately, an anode tablet is arranged above the sealing pad of the upper side of the plate body, the anode tablet, sealing pad and the plate body are connected with each other through two rivets, a nickel connection sheet and an aluminum tag are arranged separately at the upper end and lower end of each of the rivets. The utility model is capable of improving the large current amplifying performance of the battery; replacing the welding way with the riveting connection way, the nickel connection sheet is connected to the anode tablet, which eliminates the inner resistance of the welding point and prevents the reduction of the tightness of the battery caused by spot-welding the nickel connection sheet at the same time.
Description
Technical field
The utility model relates to a kind of lithium ion battery, relates in particular to a kind of cover board arrangement of lithium ion battery.
Background technology
At present, most lithium ion battery cover board, be to link to each other with the volume core of inside battery by a single aluminium strip that is riveted on the cover plate compressing tablet, and by on the cover plate compressing tablet spot welding nickel strap link to each other with external circuit, battery is when high-multiplying power discharge like this, electric current by aluminium strip can not be excessive, otherwise aluminium strip will generate heat, even fusing; And because on the cover board the spot welding nickel strap can cause this solder joint place internal resistance bigger than normal, battery should generate heat at the place when heavy-current discharge, melts the beneath sealing gasket of anodal compressing tablet, thereby causes battery sealing-performance to descend; Simultaneously, when spot welding nickel strap on anodal compressing tablet, the vibrations of welding machine can cause the reduction of anodal compressing tablet and cover plate riveting intensity, thereby cause anodal compressing tablet loosening, and the sealing of battery descends.
Summary of the invention
The purpose of this utility model provides a kind of lithium ion battery cover board, and this cover plate not only has the function of common cover, and can effectively improve the battery high-rate discharge capacity, and battery has good sealing characteristics in processing, use simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lithium ion battery cover board, comprise plate body and sealing gasket, and be provided with sealing gasket in the both sides up and down of plate body, described sealing gasket is in the same place by rivet with plate body.
The top of above-mentioned plate body upside sealing gasket is provided with anodal compressing tablet, and anodal compressing tablet by rivet and sealing gasket, plate body rivet clasp together.
The top of above-mentioned anodal compressing tablet is provided with brace, and brace is in the same place by rivet and anodal compressing tablet, sealing gasket and plate body rivet clasp.
The sealing gasket of above-mentioned plate body downside below is provided with lug, and lug by rivet and sealing gasket, plate body rivet clasp together.
The top and bottom of above-mentioned each rivet are respectively arranged with brace and lug.
Above-mentioned anodal compressing tablet, sealing gasket and plate body are in the same place by two rivet rivet clasps.
Above-mentioned brace adopts nickel material to make.
Above-mentioned lug adopts aluminum to make.
The beneficial effects of the utility model are: lithium ion battery cover board described in the utility model is owing to adopted two discharge circuits, battery is when high-multiplying power discharge, current ratio by aluminium pole ears is less, the heat that aluminium pole ears sends is fewer, be difficult for fusing, simultaneously since the nickel brace by the rivet rivet clasp on plate body, eliminated that the place's internal resistance of spot-welding technology solder joint is bigger than normal, the shortcoming of easy heating, therefore can be with the sealing gasket fusing of anodal compressing tablet below, thus the sealing of battery guaranteed.
Description of drawings
1 is plate body among the figure, and 2 is rivet, and 3 is lug, and 4 is brace, and 5 is sealing gasket, and 6 is anodal compressing tablet.
Embodiment
Be described in further detail below in conjunction with 1 pair of the utility model of accompanying drawing, a kind of lithium ion battery cover board, comprise plate body 1, the upside of plate body 1 and downside are provided with sealing gasket 5, above plate body upside sealing gasket, be provided with anodal compressing tablet 6, anodal compressing tablet 6, sealing gasket 5 are in the same place by two rivet 2 rivet clasps with plate body 1, are respectively arranged with nickel brace 4 and aluminium pole ears 3 in the top and bottom of each rivet 2.
