Description
Technical field
The utility model belongs to battery pole piece preparing technical field, is specifically related to a kind of power lithium ion battery pole piece preparation facilities and preparation technology thereof.
Background technology
It is high that lithium ion battery has output voltage, and specific energy is high, discharging voltage balance, the feature had extended cycle life.So lithium ion battery is widely used in notebook computer, digital camera, field of mobile phones; And more and more obtain application in dynamic field, energy storage field.Because power and energy storage field use lithium battery all need many strings, how also just can satisfy the demands afterwards, therefore battery with two side terminals is had higher requirement.
At present along with the continuous lifting of automation degree of equipment, the uncontrollable factor in lithium ion battery production process reduces gradually, and battery consistency is also more and more higher.But often there is battery pole piece pair roller in process prepared by battery pole piece after, just enter rolling step when pole piece does not have timely and effective uniform expansion; A kind of scheme is that battery pole piece does not toast direct winding, and due to timeliness effect, the battery core pole piece spooled expands and causes electric core winding tension, and easily cause sepage difficulty, the internal resistance of cell raises, and circulation is deteriorated; Another kind of scheme is that battery pole piece toasts after rolling, because the battery pole piece unbalance stress after rolling, inner ring and outer ring bounce-back thickness can be inconsistent, cause the consistency of battery core internal resistance, circulation etc. to be deteriorated, and easily occur the problem that battery shortens.
Utility model content
The purpose of this utility model is overcome defect of the prior art and provide one that battery pole piece can be made before rolling fully to expand, and battery pole piece thickness is even, when core size after battery winding is even, core external diameter variance is less than 0.01 and the finished product internal resistance variance power lithium ion battery pole piece preparation facilities that is less than 1.0.
The purpose of this utility model is achieved in that and comprises the twin rollers of end with wrap-up, described end is provided with the tail end of the twin rollers of wrap-up the cutting machine being with splitting winding device successively, pelleter, the baking oven of the rear wrap-up of band baking and battery pole piece up-coiler; After described band baking, the oven interior of wrap-up is provided with conveyer.
Described conveyer is feed belt or transmits one of carrying roller.
Be provided with ultrasonic welding machine in described pelleter, described ultrasonic welding machine is provided with soldering tip, and the top of described soldering tip is provided with solder joint, and the top of described solder joint is provided with several lines, and the height of described lines is less than 0.10mm.
The bottom area sum of several lines described is less than 1/2nd of the topside area of solder joint.
The material of described soldering tip is titanium alloy, one of magnadure or sintered steel.
The utility model can make battery pole piece fully expand before rolling, and battery pole piece thickness is even, and when core size after battery winding is even, core external diameter variance is less than 0.01 and the finished product internal resistance variance advantage that is less than 1.0.
