The requirement of production efficiency during sub- battery production is higher and higher.In the prior art, in order to improve the production efficiency of lithium ion battery,
The temperature when coating speed of pole piece improves pole piece drying at the same time can be generally improved, these operations are very easy to cause to apply on pole piece
Layer cracking or crimping.Especially with slurries of the LA133 as binding agent, compared to SBR, it is easier to open in coating process
Split or edge-curl phenomenon.
It is general to starch slurry using adjustment drying temperature or to closing in the prior art in order to overcome pole piece cracking or edge-curl phenomenon
The mode of the material such as alcohol or ether is added in material.The Chinese invention patent of Publication No. CN101420026A discloses a kind of lithium ion
The production method of anode, the drying process of the positive plate after coating is arranged to three phases by this method, and sets first
The temperature of drying stage and the 3rd drying stage is less than the temperature of the second drying stage, and the temperature of three drying stages is set respectively
For 60-70 DEG C, 70-90 DEG C and 60-70 DEG C.On this basis, alcohol or ether can also be added into anode sizing agent as surface
Power conditioning agent.This method can mitigate edge-curl phenomenon.But drying stage is divided into three phases by this method, process is more multiple
It is miscellaneous, the production efficiency of battery is greatly reduced, also increases cost, is unfavorable for lithium ion battery production in large-scale, high-efficiency.
