Title:
NEGATIVE ELECTRODE COMPOSITION, NEGATIVE ELECTRODE SLURRY, NEGATIVE ELECTRODE PLATE, SECONDARY BATTERY, AND ELECTRICAL DEVICE COMPRISING SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/205965
Kind Code:
A1
Abstract:
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.
