Description

A kind ofly improve primary alkaline battery sealing, fail safe and the method for storage life
Technical field
The present invention relates to and a kind ofly improve primary alkaline battery sealing, fail safe and the method for storage life, in particular to passing through primary alkaline battery sealing ring material water content control, thus the sealing of raising primary alkaline battery, fail safe and the method for storage life.
Background technology
Usually, sealing, fail safe and storage life are three important indicators weighing primary alkaline battery quality, and sealing ring determines the performance of these three indexs to a great extent.But a lot of primary alkaline battery manufacturer all only rests in the structural design of battery seal ring and the selection of sealing ring material the research of primary alkaline battery at present, and the research not deeply to sealing ring material water content.
The water content of primary alkaline battery sealing ring material is relevant with the stress intensity of material to the size of sealing ring, and the stress of the size of sealing ring and sealing ring has direct relation with the sealing property of battery.And the stress of sealing ring material also determines the size of the explosion-proof pressure that the explosion-proof valve be arranged on sealing ring can bear, therefore the water content of sealing ring material determines battery hermetization, security performance and storage life to a certain extent.The present inventor by control to sealing ring material water content, thus improves the sealing of primary alkaline battery, fail safe and storage life.
Summary of the invention
The object of the present invention is to provide and a kind ofly improve primary alkaline battery sealing, fail safe and the method for storage life.
Preferably, the object of the invention is to by primary alkaline battery sealing ring material water content control, thus improve the sealing of primary alkaline battery, fail safe and the method for storage life.Described power brick contains: the negative pole end be made up of steel band or nickel plated steel strip, be positioned at the aperture of more than 1 on negative pole end, the sealing ring injection molded by insulating polymeric material, be connected to the collector of the battery cathode (anode) on negative pole end, the active material of battery cathode (anode), the barrier film of battery, the active material of anode (negative electrode), carries battery material, serves as the box hat of the battery of battery pole collector and anode end.It is characterized in that: the water content of described sealing ring before being assembled into battery is 1%-3.5%.Described sealing ring, its insulating polymeric material is generally nylon66 fiber, NYLON610, nylon 612.Insulating material be NYLON610 and nylon 612 time, the preferred 1.5%-2.5% of water content of sealing ring, when insulating material is nylon66 fiber, the preferred 2%-3.5% of water content.
For LR03 (AAA type) battery, sealing ring is under the prerequisite meeting moisture content requirement, and the burst pressure of sealing ring explosion-proof valve is 35-120kg/cm 2, be preferably 60-90kg/cm 2; To LR6 battery (AA type), sealing ring is under the prerequisite meeting moisture content requirement, and the burst pressure of sealing ring explosion-proof valve is 30-110kg/cm 2, be preferably 50-85kg/cm 2; For LR14 (C type) battery, sealing ring is under the prerequisite meeting moisture content requirement, and the burst pressure of sealing ring explosion-proof valve is 20-50kg/cm 2, be preferably 25-40kg/cm 2; For LR20 (D type) battery, sealed nylon circle is under the prerequisite meeting moisture content requirement, and the burst pressure of sealing ring explosion-proof valve is 10-40kg/cm 2, be preferably 15-35kg/cm 2.
Should be appreciated that description and the follow-up detailed description of aforementioned cardinal principle are exemplary illustration and explanation, should not be used as the restriction to the claimed content of the present invention.
Accompanying drawing explanation
With reference to the accompanying drawing of enclosing, the following description by embodiment of the present invention is illustrated by the more object of the present invention, function and advantage, wherein:
Fig. 1 schematically shows the profile of primary alkaline battery.
Fig. 2 is that schematic diagram installed incorrectly by battery.
Embodiment
By reference to one exemplary embodiment, object of the present invention and function and the method for realizing these objects and function will be illustrated.But the present invention is not limited to following disclosed one exemplary embodiment, can be realized by multi-form to it.The essence of specification is only help various equivalent modifications Integrated Understanding detail of the present invention.
The water content of primary alkaline battery sealing ring material is relevant with the stress intensity of material to the size of sealing ring, and the size of sealing ring and the stress of sealing ring have direct relation with the sealing property of battery, therefore the water content of sealing ring material determines the quality of battery hermetization to a certain extent.
Experiment shows, uses the sealing ring that same mould is produced, also can size is different because the water content of sealing ring material is different.If sealing ring material water content is on the low side, the sealing ring made can because size is less than normal cannot with the shell close contact of battery, cause battery sealing-performance bad and the phenomenon of leakage occur; If sealing ring material water content is higher, then sealing ring can cannot put into battery case because size is bigger than normal, even if or put into battery case, also can because of crimp cannot with battery case close contact, thus the effect of sealing can not be played well.
And if sealing ring material water content is on the low side, after sealing ring sealing, because sealing ring material stress is comparatively large, sealing ring and battery case can not close contacts, still cannot play good sealing function.Carry out shell in process of production difficulty during the program of sealing ring crimping process is also significantly improved.
In addition, due to the water content of primary alkaline battery sealing ring material and its stress closely related, and the stress of sealing ring material determines the size of the explosion-proof pressure that the explosion-proof valve be arranged on sealing ring can bear.If the explosion-proof pressure that explosion-proof valve can bear is bigger than normal, when cell internal pressure increases fast, explosion-proof valve may be blasted because cannot normally open, and brings personal injury and property loss to consumer.If the explosion-proof pressure that explosion-proof valve can bear is less than normal, pressure less in battery can break through explosion-proof valve, thus causes battery leakage, will damage electrical equipment, and battery life will be caused to terminate.Therefore the water content of battery seal ring material is related to security performance and the useful life of battery.
Experimental result shows, and use the sealing ring that same mould is produced, the explosion-proof pressure that explosion-proof valve can bear also can be different because of the difference of sealing ring material water content.If the water content of sealing ring material is on the low side, then because stress is comparatively large, the explosion-proof pressure that explosion-proof valve can bear is bigger than normal; If the water content of sealing ring material is higher, although solve excessive, the unbalanced problem of stress, but can be soft and explosion-proof valve can be born explosion-proof pressure is less than normal owing to crossing, the requirement for explosion-proof pressure cannot be met.
Therefore, by the water content control of sealing ring a suitable scope, most important for producing sealing ring that size and explosion-proof pressure all meet the demands.
