The invention discloses a pole plate material of a lithium ion battery. The electrode plate material of the lithium ion battery includes 5 to 70 parts by weight of a non-buffering active material; and 30 to 95 parts by weight of a buffering active material. In the present invention, by adding a specific proportion of buffer material (such as graphite particles), the non-buffer active material itself or the shell can be prevented from being damaged or broken during the rolling step, so the cycle life of the battery can be improved. |
