Abstract
The invention relates to a plastic shell of a power lithium battery with a blocking seal groove on an upper cover. The plastic shell consists of the upper cover and a lower shell. The plastic shell is characterized in that the blocking seal groove is arranged around the combined position of the inside of the upper cover and the upper port of the relative lower shell. The plastic shell has the advantages that the blocking seal groove arranged on the upper cover prevents electrolyte from overflowing so as to protect the adhesive at the combined position of the upper cover and the upper port of the lower shell from being corroded, the adhesive mode can be popularized, and the power lithium battery adopting the plastic shell structure can be widely applied. Simultaneously, a sealing rubber strip for resisting electrolyte corrosion in the blocking seal groove also plays a good role in sealing so as to ensure good sealing effect of the battery and greatly improve the yield. The process is simple and the cost is low.
Description
Technical field
The invention belongs to dynamic lithium battery, relate in particular to the plastic shell of power lithium battery that a kind of loam cake has blocking seal groove.
Background technology
Dynamic lithium battery is brought into use the environment-friendly type plastic shell, its loam cake and the method that adopts heat seal being connected of lower house more.Its shortcoming is the bad control of technology, can occur somewhere gas leakage during hot pressing, causes the monoblock battery to be scrapped; Next is that size is difficult to control after the heat seal, and the consistency of integral product is poor, causes outward appearance not attractive in appearance.The industry begins loam cake on probation and lower house outside bonding mode.Though this kind mode technology has simply overcome the shortcoming of heat seal process, is in for a long time in the R﹠D process, is not applied in the formal product.Its main cause is that the electrolyte of lithium battery all has corrosion and solvation to any adhesive.So far also be not applicable to the corrosion resistant adhesive that plastic shell of power lithium battery is bonding on the market, influenced the extensive use of plastic shell of power lithium battery.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology; and provide a kind of loam cake to have the plastic shell of power lithium battery of blocking seal groove; the blocking seal groove that loam cake is provided with stops the excessive of electrolyte; can protect the adhesive of loam cake and lower house binding site suitable for reading not to be corroded; can promote bonding mode, the dynamic lithium battery employing is moulded shell structure and is able to extensive use.
The present invention for achieving the above object, by the following technical solutions: a kind of loam cake has the plastic shell of power lithium battery of blocking seal groove, comprise by what loam cake and lower house constituted and mould shell, it is characterized in that: the inboard lower house binding site periphery suitable for reading relatively of described loam cake is provided with blocking seal groove.
Be provided with the sealing joint strip of electrolyte resistance corrosion in the blocking seal groove of described loam cake inboard.
The lateral wall of described blocking seal groove and lower house lateral wall suitable for reading plugs together the position and is provided with adhesive-layer.
Beneficial effect: the blocking seal groove that loam cake is provided with stops the excessive of electrolyte, can protect the adhesive of loam cake and lower house binding site suitable for reading not to be corroded, and can promote bonding mode, and the dynamic lithium battery employing is moulded shell structure and is able to extensive use.The sealing joint strip of electrolyte resistance corrosion is also brought into play good sealing function in the blocking seal groove simultaneously, has guaranteed the excellent sealing effect of battery, and qualification rate increases substantially.Technology is simple, cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure, a kind of loam cake has the plastic shell of power lithium battery of blocking seal groove, comprises by what loam cake 1 and lower house 2 constituted moulding shell, and the inboard lower house binding site periphery suitable for reading relatively of described loam cake is provided with blocking seal groove 3.Be provided with the sealing joint strip 4 of electrolyte resistance corrosion in the blocking seal groove of described loam cake inboard.The lateral wall of described blocking seal groove and lower house lateral wall suitable for reading plugs together the position and is provided with adhesive-layer 5.
During assembling, will dose sealing joint strip in the prefabricated loam cake blocking seal groove, along the lateral wall coating adhesive of blocking seal groove, at lower house lateral wall coating adhesive suitable for reading, loam cake fastens, and loam cake and lower house junction suitable for reading promptly forms adhesive-layer, and loam cake and lower house are intact bonding.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1. a loam cake has the plastic shell of power lithium battery of blocking seal groove, comprises by what loam cake and lower house constituted moulding shell, and it is characterized in that: the inboard lower house binding site periphery suitable for reading relatively of described loam cake is provided with blocking seal groove.
2.
Loam cake according to claim 1 has the plastic shell of power lithium battery of blocking seal groove, it is characterized in that: the sealing joint strip that is provided with the electrolyte resistance corrosion in the blocking seal groove of described loam cake inboard.
3. loam cake according to claim 1 has the plastic shell of power lithium battery of blocking seal groove, it is characterized in that: the lateral wall of described blocking seal groove and lower house lateral wall suitable for reading plugs together the position and is provided with adhesive-layer.
