Abstract
The utility model discloses a cylindrical lithium battery, which comprises a casing (1) and a bare electric core (2) arranged in the casing (1), wherein electrolyte (6) is arranged between the casing (1) and the bare electric core (2), a positive electrode conducting wire (5) and a negative electrode conducting wire (5) are respectively led out from the upper end and the lower end of the bare electric core (2), at least one end of the upper end and the lower end of the casing (1) is provided with an opening, the conducting wires (5) arranged on the bare electric core (2) are led out from the opening part of the casing, and sealing glue (3) is adopted for sealing the opening part of the casing (1). When the structure of the utility model is adopted, the conducting wires of the upper end and the lower end of the electric core are led out from the opening of the upper end and the lower end of the casing, the sealing glue is used for sealing the opening of the casing of the lithium battery, the structure is simple, the cost is low, and the production efficiency is also improved.
Description
Technical field:
The utility model relates to field of batteries, is a kind of column type lithium battery concretely.
Background technology:
The column type lithium battery of prior art, comprise housing, be arranged on the naked electric core in the housing, between housing and naked electric core, electrolyte is housed, described housing upper end open also is provided with enclosed slot on the periphery of upper end, adopt block that opening is sealed, described block places on the enclosed slot, and be lined with the insulated enclosure circle thereon, the housing upper end-face edge bends inwards and pushes down insulated enclosure circle and block, thereby play the effect of sealing, the both positive and negative polarity lead is drawn at the two ends up and down of naked electric core respectively, and the upper end wire bonds is on block, and the lower end wire bonds is on the housing inner bottom surface.Prior art is sealed comparatively complicated to the column lithium battery, need establish enclosed slot on housing and adopt insulated enclosure circle and block to seal, and complex structure has increased production cost.
The utility model content:
The technical problems to be solved in the utility model provides the simple column type lithium battery of a kind of enclosuring structure.
Technical solution of the present utility model is, the column type lithium battery of following structure is provided, and comprises housing, is arranged on the naked electric core in the housing, between housing and naked electric core electrolyte is housed, and the both positive and negative polarity lead is drawn at the two ends up and down of naked electric core respectively.
Described housing is at least one end opening up and down, and the lead on the naked electric core is drawn from the opening part of housing, adopts the opening part sealing of fluid sealant with housing.
Adopt after the above structure compared with prior art, the utlity model has following advantage: adopt the utility model structure, the upper and lower side lead of naked electric core is drawn from the upper and lower side opening part of housing, come the opening of sealed lithiam battery housing with fluid sealant, simple in structure, cost is low, has also improved production efficiency.
As improvement, on the inwall at shell nozzle place, be provided with screw thread, like this, when using the fluid sealant sealing, improved the cohesive force of fluid sealant and inner walls effectively.
Description of drawings:
Accompanying drawing is the structural representation of column type lithium battery of the present utility model.
Shown in the figure: 1, housing, 2, naked electric core, 3, fluid sealant, 4, the plastics catch, 5, lead, 6, electrolyte.
Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Column type lithium battery of the present utility model comprises housing 1, is arranged on the naked electric core 2 in the housing 1, between housing 1 and naked electric core 2 electrolyte 6 is housed, and both positive and negative polarity lead 5 is drawn at the two ends up and down of naked electric core 2 respectively.
Described housing both ends open about in the of 1, the upper end lead of naked electric core 2 is drawn from the upper end open of housing 1, and the lower end lead of naked electric core is drawn from the lower ending opening of housing 1, adopts upper end open place and the lower ending opening place sealing of fluid sealant 3 with housing 1; Described fluid sealant 3 is that viscosity height, intensity height do not react with electrolyte.
The upper end open place and the lower ending opening place of housing 1 are equipped with plastics catch 4, and described plastics catch 4 is provided with the centre bore that passes for lead 6.
On the inwall at housing 1 upper end open place and lower ending opening place, be equipped with screw thread.
Claims (2)
1. column type lithium battery, comprise housing (1), be arranged on the naked electric core (2) in the housing (1), between housing (1) and naked electric core (2), electrolyte (6) is housed, both positive and negative polarity lead (5) is drawn at the two ends up and down of naked electric core (2) respectively, it is characterized in that: at least one up and down end opening of described housing (1), lead (5) on the naked electric core (2) is drawn from the opening part of housing, adopts the opening part sealing of fluid sealant (3) with housing (1).
