一种锂离子电池的负极极片及包含该极片的电池
摘要：
本发明属于锂离子电池技术领域，尤其涉及一种锂离子电池的负极极片，所述负极极片设置有裂纹结构，所述裂纹结构开口设置在极片表层。裂纹结构的设置能够大幅提高极片对电解液的吸收速度，降低锂离子电池注液后的静置时间。在采用上述裂纹结构的锂离子电池中，裂纹的存在为电解液在极片中的快速传输提供了一条高速公路，极大的提高了电池的充放倍率性能。此外，本发明还公开了一锂离子电池。
摘要（英）：

The invention belongs to the technical field of lithium ion battery, and especially relates to a lithium ion battery negative electrode sheet. The negative electrode sheet is provided with a crack structure with an opening arranged on the surface layer of the electrode sheet. With the crack structure, the absorption speed of the electrode sheet upon electrolyte can be greatly improved, and lithium ion battery settlement time can be reduced after injection. In a lithium ion battery with the crack structure, with the crack, a highway is provided for fast transmission of the electrolyte in the electrode sheet, such that battery charge/discharge rate performance can be greatly improved. The invention also discloses a lithium ion battery.
