Beschreibung
Zusammenfassung:	The invention provides lithium ion battery cathode slurry, a cathode and a battery. The cathode slurry comprises a cathode active material, an agglomerant and a dispersing agent. The dispersing agent comprises a tartrate. With adopting the tartrate as the dispersing agent for the cathode slurry, dispersity of the cathode slurry is raised; viscosity and stability of the cathode slurry are improved; compatibility of the cathode slurry and electrolyte is improved, such that a SEI film with stable performance can be formed on the surface of the cathode, and decomposition of PC-based electrolyte can be avoided so as to improve battery performance.
