Abstract
The utility model provides a box hat cylindrical lithium ion battery, the box hat includes the electric core encapsulation section of downside and the block encapsulation section of upside, the outside of electricity core encapsulation section is equipped with the nickel coating, and the cross section internal diameter of electric core encapsulation section is less than the cross section internal diameter of the arbitrary department of block encapsulation section, and integrative airtight fixedly connected with block layer board between the upper end of electric core encapsulation section and the lower extreme of block encapsulation section, electric core are located electric core encapsulation section, and the block seals presses on the block layer board, and the upper portion punching press after envelope of block encapsulation section is on the block. The ascending shrinkage joint of opening has been seted up on the upper portion of block encapsulation section, and the shrinkage joint is triangle -shaped. The inner space of block encapsulation section is cylinder or bottom surface diameter big -end -up's cone. Block layer board level setting or be low setting the in outer high. The oral area of box hat is thick, and the part is thin below the oral area, and this section outside has the nickel coating, and after electric core went into shell, the some end, drying, notes liquid, weld to block a shot, box hat thickness junction (the layer board of blocking a shot promptly) was held the block, is closed up the box hat.
Description
Technical field
The utility model relates to a kind of lithium ion battery, particularly relates to a kind of box hat cylindrical lithium ion battery.
Background technology
Lithium ion battery energy density is large, good rate capability, and safety, environmental protection, become mankind's main energy sources product.At present, box hat cylindrical lithium ion battery technical maturity, automaticity is high, and battery consistency is good, and cost is low, is widely used in electronics and power energy field.In box hat cylindrical lithium ion battery manufacturing process, battery core needs after entering shell to carry out box hat slot rolling operation, the box hat Incoming Quality Control that the stable needs of slot rolling operation are strict and production process control, the nickel coating of destructible box hat outside in slot rolling process, serious meeting damages box hat, cause the leakage of lithium ion battery later stage, and slot rolling process can produce metallic dust, if control not strict, then can affect the charge-discharge performance of lithium ion battery.In addition, the bad battery core occurred in production process, after slot rolling, battery core can only destroy, and only box hat re-assemblies, and battery core is not easily done over again process.
Summary of the invention
The purpose of this utility model is to provide a kind of without the need to slot rolling operation, preparation is simple, efficiency is high, cost is low box hat cylindrical lithium ion battery.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of box hat cylindrical lithium ion battery, comprise box hat, box hat is rotary body, battery core is provided with in box hat, box hat upper end above battery core is packaged with block, it is characterized in that, box hat comprises the battery core encapsulation section of downside and the block encapsulation section of upside, the outside of battery core encapsulation section is provided with nickel coating, the cross sectional inner diameter of battery core encapsulation section is less than the cross sectional inner diameter at block any place of encapsulation section, between the upper end of battery core encapsulation section and the lower end of block encapsulation section, one is airtight is fixedly connected with block supporting plate, battery core is positioned at battery core encapsulation section, block envelope is pressed on block supporting plate, be encapsulated on block after block encapsulation section top punching press.
According to described box hat cylindrical lithium ion battery, it is characterized in that, the top of described block encapsulation section offers the shrinkage joint of opening upwards, and shrinkage joint is triangle.
According to described box hat cylindrical lithium ion battery, it is characterized in that, the inner space of described block encapsulation section is the up big and down small cone of cylinder or basal diameter.
According to described box hat cylindrical lithium ion battery, it is characterized in that, described block pallets level arranges or is high outside and low outside setting.
The utility model primarily of box hat, block and battery core three part composition, the oral area (encapsulation section of namely blocking a shot) of box hat is thick, oral area is thin with lower part (i.e. battery core encapsulation section), and this section of outside is with nickel coating, after battery core enters shell, the some end, drying, fluid injection, the complete block of welding, block is held in box hat thickness junction (supporting plate of namely blocking a shot), box hat is closed up, mechanical stamping encases block and completes encapsulation, the manufacturing process of this lithium ion battery is without the need to slot rolling, operation is simple, and therefore production efficiency is high, and battery cost of manufacture is low.
