Description
Technical field
The present invention relates to a kind of cascaded structure, relate in particular to a kind of cascaded structure of electric core.
Background technology
Lithium ion battery (Li-ion Batteries) is the lithium battery development.The button cell of using in the camera just belongs to lithium battery.The positive electrode of lithium battery is manganese dioxide or thionyl chloride, and negative pole is a lithium.Battery promptly had voltage after the battery assembling was accomplished, and need not charge. and this battery also can charge, but cycle performance is bad, in the charge and discharge cycles process, forms Li dendrite easily, causes internal short-circuit of battery, so this generally speaking battery is forbidden charging.Afterwards, it was negative pole that sony corporation of japan has been invented with the raw material of wood-charcoal material, made anodal lithium battery with the compound that contains lithium, in charge and discharge process, did not have lithium metal to exist, and had only lithium ion, Here it is lithium ion battery.When battery is charged, there is lithium ion to generate on the positive pole of battery, the lithium ion of generation arrives negative pole through electrolyte movement.And be layer structure as the carbon of negative pole, and it has a lot of micropores, and the lithium ion that reaches negative pole just is embedded in the micropore of carbon-coating, and the lithium ion of embedding is many more, and charging capacity is high more.Equally, when battery is discharged (we use the process of battery), the lithium ion that is embedded in the negative pole carbon-coating is deviate from, and it is anodal to move back again.
Lithium ion battery generally is made up of electric core and metallic plate, and in order to dwindle the volume of entire cell, industry can be together in series electric core usually, and in the prior art, the electric core that people normally will connect directly welds together.Only, this kind cascaded structure makes that the structural strength of battery is lower, thereby influences the useful life of battery.
Therefore, be necessary to provide a kind of electric core cascaded structure that overcomes above-mentioned defective.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and can prolong the battery electric core cascaded structure in useful life.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of electric core cascaded structure; It comprises: several electric core groups, several metallic plates and a pair of lug, said electric core group comprise the first electric core group, the second electric core group, the 3rd electric core group and the 4th electric core group, and said metallic plate comprises first metallic plate, second metallic plate, the 3rd metallic plate, the 4th metallic plate and the 5th metallic plate; The bending part that said second, third metallic plate is respectively equipped with body and extends from the body bending; The negative pole anodal and the second electric core group of the said first electric core group welds with first metallic plate mutually, and the negative pole of the said first electric core group welds with the body of second metallic plate mutually, and the positive pole of the said second electric core group welds with the body of the 3rd metallic plate mutually; The positive pole of the said the 3rd electric core group welds with the bending part of second metallic plate mutually; The negative pole of the said the 3rd electric core group welds with the 4th metallic plate mutually, and the negative pole of the said the 4th electric core group welds with the bending part of the 3rd metallic plate mutually, and the positive pole of the said the 4th electric core group welds with the 5th metallic plate mutually; Wherein a lug is installed on the 4th metallic plate, and another lug is installed on the 5th metallic plate.
The invention has the beneficial effects as follows: above-mentioned electric core cascaded structure has higher intensity, thereby has prolonged the useful life of battery.
