摘要： The present invention provides a negative electrode slurry, a negative electrode plate and an electrochemical energy storage device. The negative electrode slurry comprises a solvent and a solid component dispersed in the solvent. The solid component comprises a negative electrode active material, a water-soluble binder and a dispersant. The negative electrode active material comprises a carbon-type active material. The dispersant comprises an A dispersant and a B dispersant, the A dispersant is a cellulose-type dispersant, the B dispersant is at least one of poly(acrylic acid)-type dispersant, polyacrylate-type dispersant and polyacrylamide-type dispersant. Under a combined effect of the A dispersant and the B dispersant, they can ensure that the electrochemical energy storage device has excellent dynamic performance, which can prevent lithium (or sodium, magnesium and zinc) from precipitating under condition of rapid and large current charging, meanwhile they can ensure that the electrochemical energy storage device has excellent cycle performance.
