石墨颗粒
摘要：
本发明提供了一种用于锂二次电池阴极的石墨颗粒，其特征在于，当将一些石墨颗粒与有机粘合剂的混合物应用到电流收集器上时，该石墨颗粒不容易在在电流收集器的平面方向定向排列。本发明还提供了一种用于锂二次电池阴极的石墨颗粒，其在使用过程中吸收和释放离子，该石墨颗粒在其中具有气孔，其能够吸收在吸收和释放离子时所产生的电极的膨胀和收缩。本发明还提供了一种用于锂二次电池阴极的石墨颗粒，该石墨颗粒含有一些定向排列的平面相互不平行的部分。
摘要（英）：

The present invention provides a graphite particle for the cathode of a lithium secondary battery. When the mixture of some graphite particles and an organic bond are applied on a current collector, the graphite particles are not easy to be in a direction arrangement on the plane of the current collector. The present invention also provides a graphite particle for the cathode of a lithium secondary battery, wherein, the graphite particle absorbs or discharges ions, and the graphite particle is capable of absorbs expansion and contraction of the electrodes when absorbing and discharging ions. The present invention also provides a graphite particle the cathode of a lithium secondary battery, wherein, the graphite particle has parts with planes un-parallel in a direction arrangement.
