Abstract
The utility model discloses a three-dimensional lithium ion battery distance ring with an anode distance piece. The three-dimensional distance ring comprises a distance ring body for isolating a positioning core and a cover plate for a lithium ion battery, wherein the distance ring body extends downwards to form a projecting distance piece on one side surface passing through a groove of a battery core anode lug; the projecting distance piece is 4-6 millimeters in height and 0.4-0.6 millimeter in thickness. The three-dimensional distance ring extends downwards to form the projecting distance piece 7 on the side face passing through the groove of the battery core anode lug during assembly of the battery, and the distance piece is used for isolating the battery core anode lug and a cathode piece, so that a manual sticking way of high-temperature gummed paper used in a conventional lithium ion battery assembly is replaced, the problems of crease and powder removal of a pole piece exposed out of the upper part of a battery core due to obliqueness at different degrees and non-uniform sticking force in the stuck high-temperature gummed paper are solved, the product quality is ensured, the potential safety hazard of the battery core is reduced, and the safety and the reliability of the battery are enhanced.
Description
Technical field
The utility model belongs to technical field of lithium ion, relates to a kind of lithium ion battery assembly, is specifically related to the three-dimensional spacer ring of a kind of lithium ion battery with anodal spacer.
Background technology
The advantages such as lithium ion battery tool is high with voltage, electricity capacity large, long circulation life, memory-less effect, quality is light, working range is wide, performance and the capacity requirement of existing market to lithium ion battery is more and more higher, impel the increase of lithium ion battery body internal cell core auxiliary material, allow battery utilize space also dwindling gradually.Lithium ion battery comprises housing, cover plate assembly, battery and electrolyte, and housing and cover plate assembly form a confined space conventionally, and battery and electrolyte are contained in this confined space.Between battery and cover plate, use the isolation of three-dimensional spacer ring, and paste high tempreture tape by the top at battery anode ear place and stop contacting of anode ear and negative plate, avoid causing short circuit.As shown in Figure 1, lithium ion battery 1 is in the time of assembling, high tempreture tape 4 is pasted on the anode ear top that need connect in battery 2, again spacer ring 5 is just being overlapped to battery, negative electrode lug covers, then will be just, negative electrode lug is connected bonnet upper cover plate 6. because this lithium ion battery is when the production line batch jobs with cover plate, by artificial stickup high tempreture tape 4, the high tempreture tape 4 of pasting there will be in various degree crooked, and the stickup dynamics inequality pole piece wrinkle that easily cause battery top to expose, shedding, therefore hand paste operation not only affects quality, and the potential safety hazard that can make battery exist, have influence on the security reliability of battery.
Summary of the invention
The purpose of this utility model is to solve the pole piece wrinkle shedding of battery top, problem that difficulty hand-manipulated is large, provide a kind of lithium ion battery with anodal spacer three-dimensional spacer ring structure, anodal spacer by from three-dimensional spacer ring anode ear place to downward-extension, make battery anode ear and negative plate isolation, solved the problems referred to above that prior art exists.
The technical scheme that the utility model adopts is, the three-dimensional spacer ring of a kind of lithium ion battery with anodal spacer, comprise that lithium ion battery is used for isolating the spacer ring of location battery and cover plate, described spacer ring passes the side of groove in battery anode ear, downwards the outstanding spacer of elongation moulding one.
The three-dimensional spacer ring of lithium ion battery with anodal spacer described in the utility model, is further characterized in that,
Described outstanding spacer height is 4～6 millimeters, and thickness is 0.4～0.6 millimeter.
The utility model is with the three-dimensional spacer ring of lithium ion battery of anodal spacer, in the time of assembled battery, by pass the side of groove in battery anode ear, the outstanding spacer of elongation moulding one is isolated battery anode ear and negative plate downwards, the mode of the high tempreture tape of the artificial stickup while having substituted existing lithium ion battery assembling, solve crooked in various degree that the high tempreture tape pasted occurs, and the stickup dynamics inequality pole piece wrinkle that easily cause battery top to expose, shedding, problem, guarantee product quality, reduce the potential safety hazard that battery exists, improve the security reliability of battery.
Accompanying drawing explanation
Fig. 1 is existing lithium ion battery package assembly schematic diagram;
Fig. 2 a and Fig. 2 b are the lithium ion battery three-dimensional spacer ring structural representation of the utility model with anodal spacer.
In figure, 1. lithium ion battery, 2. battery, 3. anode ear passes groove, 4. high tempreture tape, 5. spacer ring, 6. cover plate, 7. spacer.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The three-dimensional spacer ring of a kind of lithium ion battery with anodal spacer, as shown in Figure 2, comprise that lithium ion battery is used for isolating the spacer ring 5 of location battery 2 and cover plate 6, described spacer ring 5 passes the side of groove 3 in battery 2 anode ears, the outstanding spacer 7 of elongation moulding one downwards, described outstanding spacer 7 is highly 4～6 millimeters, and thickness is 0.4～0.6 millimeter.
The utility model is with the three-dimensional spacer ring of lithium ion battery of anodal spacer, it is the side that passes groove 3 in spacer ring 5 in anode ear, elongation moulding one projecting height is 4～6 millimeters downwards, thickness is the spacer 7 of 0.4～0.6 millimeter, make spacer ring 5 become a three-dimensional spacer ring, it is isolated battery 2 anode ears and negative plate by the outstanding spacer 7 of spacer ring 5, prevention anode ear contacts with negative plate, while having substituted in this way existing lithium ion battery assembling, isolates anode ear, contacts with negative plate with the artificial high tempreture tape of pasting.
The utility model is with the three-dimensional spacer ring of lithium ion battery of anodal spacer, solved while assembling lithium ion battery in order to stop contacting of anode ear and negative plate in the past, paste high tempreture tape owing to using, the high tempreture tape 4 occurring is crooked in various degree, and high tempreture tape 4 stickup dynamics inequalities easily cause the pole piece wrinkle that battery 2 tops expose, the problem of shedding, guarantee lithium ion battery product quality, reduced the potential safety hazard that battery exists, improved the security reliability of battery.
Above-mentioned execution mode is an example of the present utility model; not enforcement and the interest field for limiting utility model; all equivalences of making according to the content described in the utility model patent protection scope change and modify, and all should be included in the utility model claim.
