Abstract
The utility model discloses a cylindrical battery which comprises a shell and a battery cap positioned at an end of the shell, wherein a battery sealing and insulating ring is arranged between the shell and the cap; non-conductive insulating paint is coated on a positive pole or a negative pole exposed out of the shell of the battery, non-conductive insulating paint layers are formed after the paint is dried and can achieve good insulating effect, the thickness of the non-conductive insulating paint layers are smaller than 0.05mm, and the non-conductive insulating paint can be various paints used for coating enamel covered wires. The cylindrical battery provided by the utility model can realize reliable and easy operation with low cost and has good insulating effect, and the thickness of the formed protective layer is small and is high-temperature resistant.
Description
Technical field
The utility model relates to battery, relates in particular to a kind of positive and negative insulating method that is short-circuited of battery that prevents.
Background technology
Existing cylindrical battery, as AA, the battery of models such as AAA, the housing of general battery is as the negative pole of battery, at one end be provided with block, block is as the positive pole of battery, be provided with the cell sealing insulated ring between block and the housing, be short-circuited for fear of between the battery plus-negative plate, existing way is: wait with non-conductive film (PVC film) or paster to separate battery plus-negative plate between positive pole that may be short-circuited and negative pole, the shortcoming of this class way is: non-conductive film generally all surpasses the thickness of 0.05MM, if non-conductive film is done too thinly then cracky, do not have the effect that prevents short circuit; If non-conductive film is done too thickly then is increased battery size.Non-conductive film non-refractory easily is heated back distortion and loses the effect that prevents short circuit.Existing battery insulation way makes employed material and operating cost also than higher.
The utility model content
The utility model be intended to overcome the deficiencies in the prior art provide a kind of reliably, cheaply, thin thickness, resistant to elevated temperatures, easy-operating cylindrical battery.
To achieve these goals, the utility model is designed a kind of cylindrical battery, comprise housing and the block that is positioned at an end of housing, between housing and block, be provided with the cell sealing insulated ring, the non-conductive insulating paint of coating on the negative or positive electrode outside being exposed to battery container, paint forms non-conductive insulating oil enamelled coating after doing, and can reach the good insulation performance effect by non-conductive insulating oil enamelled coating.
The thickness of described non-conductive insulating oil enamelled coating is less than 0.05mm.
Described non-conductive insulating paint is all kinds of paint to enamelled wire coating usefulness.
Outside the negative or positive electrode that has non-conductive insulating oil enamelled coating, paste or be enclosed with non-conductive film or paster etc., can play the effect of duplicate protection, make battery insulation more reliable.
Be exposed to the outer battery cathode of battery container.
Described non-conductive film is the PVC film.
The utility model cylindrical battery is by after anode or negative pole are coated with non-conductive insulating paint, after paint is done, form non-conductive insulating oil enamelled coating, by non-conductive insulating oil enamelled coating can reach reliably, cheaply, thin thickness, resistant to elevated temperatures, easy to operate and have a good insulation performance effect.In order further to improve the insulation degree, can wait with non-conductive film (PVC film) paster again to separate both positive and negative polarity, reach the effect of duplicate protection, make battery insulation more reliable.The utility model cylindrical battery is applied to especially than the insulation protection in the lithium battery that is easier to explode, the lithium ion battery.
Description of drawings
Fig. 1 is the battery structure schematic diagram in the utility model cylindrical battery.
Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with the accompanying drawings and the specific embodiments the utility model principle is described in further detail:
As shown in Figure 1, a kind of cylindrical battery, described battery comprises housing 1 and is positioned at the block 2 of an end of housing 1, at housing 1 with block a shot and be provided with cell sealing insulated ring 3 between 2, housing 1 is the negative pole of battery, and block 2 is the positive pole of battery, the non-conductive insulating paint of coating on the negative or positive electrode outside being exposed to battery container 1, paint forms non-conductive insulating oil enamelled coating after doing, and can reach the good insulation performance effect by non-conductive insulating oil enamelled coating.
The thickness of non-conductive insulating oil enamelled coating described in the utility model is less than 0.05mm.
In order to reach the good insulation performance effect, described non-conductive insulating paint is all kinds of paint to enamelled wire coating usefulness.
In addition,, outside the negative or positive electrode that has non-conductive insulating oil enamelled coating, paste or be enclosed with non-conductive film or paster etc., can play the effect of duplicate protection, make battery insulation more reliable for the realization insulation effect of advancing.
Non-conductive film described in the utility model is the PVC film.
After the utility model anode or negative pole are coated with non-conductive insulating paint, can separate both positive and negative polarity with non-conductive film (PVC film, paster etc.) again, reach the effect of duplicate protection.Such as being used for lithium ion batteries such as 18650 lithium ion batteries or 26650, effect is fine.Can be used in lithium ion batteries such as 18650 lithium ion batteries or 26650, effect is fine.
Claims (5)
1. cylindrical battery, comprise housing and the block that is positioned at an end of housing, be provided with the cell sealing insulated ring between housing and block, it is characterized in that: the non-conductive insulating paint of coating on the negative or positive electrode outside being exposed to battery container forms non-conductive insulating oil enamelled coating.
2. cylindrical battery according to claim 1 is characterized in that: the thickness of described non-conductive insulating oil enamelled coating is less than 0.05mm.
