Beschreibung
Zusammenfassung:	The present application discloses a negative electrode composition, a negative electrode slurry, a negative electrode plate, a secondary battery, and an electrical device comprising the secondary battery. The negative electrode composition comprises a negative electrode active material and a plasticizer, and the plasticizer comprises a polyether polyol. The negative electrode composition of the present application can effectively reduce the risk of cracking of a negative electrode film layer, and improve the electrolyte infiltration performance of the negative electrode plate, thereby improving the energy density, cycle performance and rate capability of the secondary battery. La présente demande divulgue une composition d'électrode négative, une suspension d'électrode négative, une plaque d'électrode négative, une batterie secondaire et un dispositif électrique contenant la batterie secondaire. La composition d'électrode négative comprend un matériau actif d'électrode négative et un plastifiant, et le plasti
