Beschreibung
Zusammenfassung:	This application discloses a negative electrode composition, a negative electrode slurry, a negative electrode plate, a secondary battery, and an electrical device containing the secondary battery. The negative electrode composition includes a negative active material and a plasticizer. The plasticizer includes a first plasticizer and optionally a second plasticizer. The first plasticizer includes at least one of a POSS-containing block copolymer or a polyester containing a -[O-CH(CH3)-C(=O)]-structural unit. The second plasticizer includes an organic solvent with a boiling point Tm of 160 °C to 250 °C.
