具体实施方式
下面结合附图，详细说明发明的具体实施例。
本发明提供一种锂离子电池极片的涂布方法，包括以下步骤：
步骤1：浆料制备；
准备浆料；
步骤2：选材；
选择箔带的规格，包括宽度，厚度，材料等，其中箔带的宽度为极片4的长度；涂布完成后的极片4长度、厚度均影响到卷芯的大小，根据所需卷芯的规格，来决定选择何种规格的箔带；
步骤3：涂布；
涂布时在整片箔带的纵向方向的其中一侧边缘留有不涂布的留白区41；留白区连接极耳，所以，留白区的宽度与极耳的宽度最好相等；如此，可自动留白，留白区41尺寸精确，无需涂布机跳间隙、无须人工刮片，涂布机构动作步骤减少，如此，设备开机调试时间减少，可连续涂布，涂布效率提高；无需跳间隙，所以涂布密度均匀，使电池容量一致性得到提高，合格率提高，工作效率提高，大幅提高了极片涂布质量。
步骤4：烘干；
涂布完成的极片4进入烘箱烘干；
步骤5：辊压；
将烘干之后的极片4辊压，压实；
步骤6：分切；
在箔带的横向方向进行分切，分切后的极片4宽度作为极片4的宽度；极片在卷芯时，极片的宽度为卷芯的高度；同一箔带涂布后后可分切成多种宽度不同的极片4，即可卷成多种高度不同的卷芯5，可装入规格不同的锂离子电池的保护壳；根据所需卷芯5的高度，分切出不同宽度的极片4。
如图3所示，卷芯5包括正极片43和负极片44，正极片和负极片之间设有隔膜6，所述正极片和负极片的留白区分别设有正极耳45和负极耳46。正极片和负极片的留白区41的高度为卷芯5的高度，宽度与正极耳45和负极耳46的宽度相等。
锂离子电池极片的涂布方法，自动留白区域尺寸精确，无需涂布机跳间隙、无须人工刮片；涂布密度均匀，使电池容量一致性得到提高，合格率提高，大幅提高了极片涂布质量；涂布机构动作步骤减少，连续涂布，操作简单，涂布效率提高；设备开机调试时间减少，工作效率提高；选材时根据箔带的宽度、厚度、材料等可制成不同长度、厚度、材料的极片，制成不同规格的卷芯。
本发明还提供一种采用上述涂布方法的锂离子电池极片的涂布装置，包括涂布机头1和烘箱2，所述涂布机头1包括涂布辊14，所述涂布辊14设有浆料料斗11，浆料料斗11固定在涂布辊14前上方，使浆料3可以涂在涂布辊14上的极片4上。
所述浆料料斗11连接挡料压边板12，所述挡料压边板12包括挡料板121和压边板122两部分，所述挡料板121与浆料料斗11连接，挡住浆料3，防止浆料3溢出料斗11，所述压边板121与挡料板121活动连接，所述压边板122的宽度与留白区41的宽度相等，阻挡浆料在留白区41涂布，压边板122可更换，根据极片4所需留白区41的宽度不同更换不同宽度的压边板122。
涂布辊14上方设有刮刀13，所述刮刀包括涂布刮刀132和留白刮刀131两部分，所述留白刮刀131与涂布刮刀132接触的一端与压边板122外侧对应平齐，留白刮刀131的宽度与压边板122的宽度相等；即留白刮刀122可进一步对留白区41的浆料3进行挂除，保证留白区41的宽度和精度，与转移跳间隙涂布和挤压跳间隙涂布方式对比，极片4面密度一致，极,4涂布面密度精度提高了40%；涂布完成后的极片4分为其中一边缘的宽度小的矩形留白区41，和其余大部分宽度大的矩形涂布区42。
