Description
Technical field
A kind of a kind of lithium battery of present invention design, and in particular to cylindrical lithium battery with safety guard.
Background technology
Lithium ion battery is a kind of rechargeable battery, and it relies primarily on lithium ion, and movement carrys out work between a positive electrode and a negative electrode.In charge and discharge process, Li+ comes and goes embedded and deintercalation between two electrodes：During rechargable battery, from positive pole deintercalation, through the embedded negative pole of electrolyte, negative pole is in rich lithium state for Li+；It is then contrary during electric discharge.The general battery for adopting the material containing elemental lithium as electrode.It is the representative of modern high performance battery.Existing lithium battery security performance is not high, it occur frequently that explosion accident, causes larger potential safety hazard.
The content of the invention
(1) technical problem to be solved
The technical problem to be solved in the present invention is to provide a kind of cylindrical lithium battery with safety guard, and its security performance is high, with explosion prevention function.
(2) technical scheme
To solve above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of cylindrical lithium battery with safety guard, including housing (7) and battery core (8), the battery core (8) is arranged in the housing (7), electrolyte (6) is housed between the housing (7) and battery core (8), housing (7) upper end is open, battery core (8) upper end is provided with wire (1), lower end is provided with lower wire (9), housing (7) upper end is provided with sealant layer (4) and seals the housing (7), the upper wire (1) is through the sealant layer (4), sealant layer (4) lower surface is provided with plastic sheet (5).
As preferred; sealant layer (4) top is provided with crown cap (3); overtemperature protector (2) is provided between the crown cap (3) and sealant layer (4), overtemperature protector (2) two ends connect the upper wire (1) and crown cap (3) respectively.
(3) beneficial effect
The present invention is compared to prior art, and which has the advantages that：Which on the basis of existing production technology is not changed, can improve the security performance of product, prevent blast, and low cost, simple structure are novel in design, with practicality.
Description of the drawings
Fig. 1 is the structural representation of the cylindrical lithium battery with safety guard of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Following examples are used to illustrate the present invention, but are not limited to the scope of the present invention.
A kind of cylindrical lithium battery with safety guard as shown in Figure 1, including housing (7) and battery core (8), the battery core (8) is arranged in the housing (7), electrolyte (6) is housed between the housing (7) and battery core (8), housing (7) upper end is open, battery core (8) upper end is provided with wire (1), lower end is provided with lower wire (9), housing (7) upper end is provided with sealant layer (4) and seals the housing (7), the upper wire (1) is through the sealant layer (4), sealant layer (4) lower surface is provided with plastic sheet (5).Sealant layer (4) top is provided with crown cap (3); overtemperature protector (2) is provided between the crown cap (3) and sealant layer (4), overtemperature protector (2) two ends connect the upper wire (1) and crown cap (3) respectively.
When the phenomenon that in use, is short-circuited etc. causes lithium battery temperature to raise suddenly, overtemperature protector can be automatically powered off, and protect lithium battery.
The present invention on the basis of existing production technology is not changed, can improve the security performance of product, prevent blast, and low cost, simple structure are novel in design, with practicality.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, on the premise of without departing from the technology of the present invention principle; some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
