| description | The invention discloses a negative electrode composition, negative electrode slurry, a negative electrode pole piece, a secondary battery and an electric device containing the secondary battery, the negative electrode composition comprises a negative electrode active material and a plasticizer, and the plasticizer comprises polyether polyol. The negative electrode composition can effectively reduce the risk of cracking of a negative electrode film layer and improve the electrolyte infiltration performance of a negative electrode plate, so that the energy density, the cycle performance and the rate capability of the secondary battery are improved.
本申请公开了一种负极组合物、负极浆料、负极极片、二次电池及含有该二次电池的用电装置，该负极组合物包括负极活性材料以及增塑剂，所述增塑剂包括聚醚多元醇。本申请的负极组合物能够有效降低负极膜层开裂的风险、提高负极极片的电解液浸润性能，从而提高二次电池的能量密度、循环性能和倍率性能。 |
