For the manufacturing mold provided by the present invention, it is possible to carry out thermocompression setting for polymer batteries with different bending degrees by changing the size of the mold and the shape and size of the positioning groove 11 and the positioning protrusion 21 .
在本发明中，需要说明的是，本发明的制作模具需要对放入的聚合物电池进行热压定型时，所述定位凹槽11和定位凸起21的内壁优选为贴有绝缘硅胶垫，而当根据本发明的制作模具需要对放入的聚合物电池进行冷压降温定型时，所述定位凹槽11和定位凸起21的内壁优选为贴有绝缘铁氟龙，以满足不同阶段电池制备工序的需要。 In the present invention, it should be noted that when the production mold of the present invention needs to carry out hot pressing and setting for the polymer battery put in, the inner walls of the positioning groove 11 and the positioning protrusion 21 are preferably pasted with insulating silica gel pads, And when the production mold according to the present invention needs to carry out cold pressure cooling and sizing of the polymer battery put in, the inner walls of the positioning groove 11 and the positioning protrusion 21 are preferably pasted with insulating Teflon to meet the needs of batteries in different stages.

需要说明的是，对于本发明所制备的聚合物电池，其在结构设计上优选为叠片式聚合物电池，其采用的隔膜、负极、正极的对齐度要满足弯折后所需包覆量，并符合安全设计准则。 It should be noted that for the polymer battery prepared in the present invention, it is preferably a stacked polymer battery in terms of structural design, and the alignment of the separator, negative electrode, and positive electrode used in it must meet the required coating amount after bending. , and complies with safe design guidelines.
具体实现上，为了保证聚合物电池的安全性，首先在结构设计上要满足一些安全设计准则。比如，对于一般结构平整的聚合物电池，其对齐度的要求如下：隔膜对负极的对齐度，要求隔膜包住负极，隔膜与负极边缘距离≥0.5mm； In terms of specific implementation, in order to ensure the safety of polymer batteries, some safety design criteria must first be met in structural design. For example, for a polymer battery with a generally flat structure, the alignment requirements are as follows: the alignment of the separator to the negative electrode requires the separator to wrap the negative electrode, and the distance between the separator and the edge of the negative electrode is ≥ 0.5mm;
负极对正极的对齐度，首先要求负极包住正极，对于容量<300mAh的电池，负极与正极边缘距离>0.0mm；对于容量≥300mAh的电池，负极与正极边缘距离≥0.2mm。其次，要求在卷绕起始和结尾处极片长度方向，负极完全包住正极，负极与正极涂敷边缘距离≥0.5mm； The alignment of the negative electrode to the positive electrode first requires the negative electrode to enclose the positive electrode. For batteries with a capacity of <300mAh, the distance between the negative electrode and the edge of the positive electrode is >0.0mm; for batteries with a capacity of ≥300mAh, the distance between the negative electrode and the edge of the positive electrode is ≥0.2mm. Secondly, it is required that the negative electrode completely encloses the positive electrode in the length direction of the pole piece at the beginning and end of winding, and the distance between the negative electrode and the positive electrode coating edge is ≥0.5mm;
隔膜对正极的对齐度，要求隔膜包住正极，对于容量<300mAh的电池，隔膜与正极剪切边距离≥5mm；对于容量≥300mAh的电池，隔膜与正极剪切边距离≥8mm。对于可弯折的聚合物电池，其难点就在于弯折后对齐度，即隔膜对负极、负极对正极、隔膜对正极的包覆。为满足对齐度的要求，可根据电池弯折曲度的大小进行对齐度的补偿，实现其安全性的可靠性。 The alignment of the separator to the positive electrode requires the separator to wrap the positive electrode. For batteries with a capacity of <300mAh, the distance between the separator and the shearing edge of the positive electrode is ≥5mm; for batteries with a capacity of ≥300mAh, the distance between the separator and the positive electrode is ≥8mm. For a bendable polymer battery, the difficulty lies in the alignment after bending, that is, the coating of the separator to the negative electrode, the negative electrode to the positive electrode, and the separator to the positive electrode. In order to meet the alignment requirements, the alignment compensation can be performed according to the bending degree of the battery, so as to realize its safety and reliability.
对于聚合物电池，其制备工艺过程依次为：极组叠片、装配、化成、热压、老化、后处理、分选。其中的关键工序为极组叠片和热压。极组叠片在保证安全设计的前提下进行，并采用涂胶隔膜，以便热压时的聚合定型；热压是在具有弧形曲度工位的制作模具上，在合适的压力和温度下，使电池聚合成型至相应的弯折曲度。 For polymer batteries, the preparation process is as follows: electrode group lamination, assembly, formation, hot pressing, aging, post-treatment, and sorting. The key processes are pole group lamination and hot pressing. The pole group lamination is carried out under the premise of ensuring the safety design, and the rubber-coated diaphragm is used to facilitate the polymerization and shaping during hot pressing; , so that the battery is polymerized and molded to the corresponding bending degree.
