SLURRY COMPOSITION, AND POSITIVE ELECTRODE AND LITHIUM SECONDARY BATTERY COMPRISING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18030958 titled 'SLURRY COMPOSITION, AND POSITIVE ELECTRODE AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Simplified Explanation
The patent application describes a slurry composition for use in manufacturing a positive electrode for a lithium secondary battery. The slurry composition includes several components such as a positive electrode active material, an electrically conductive material, a binder, a thickener, an additive, and a solvent.
- The slurry composition improves the processability in the slurry coating process for manufacturing the positive electrode.
- The slurry composition contains a thickener called lithiated carboxymethyl cellulose, which helps to provide thixotropy.
- Thixotropy allows the slurry to have sufficient flowability and flexibility to adapt to changes in the slurry coating rate.
- The slurry composition also includes an additive called a carbodiimide-based compound, which further enhances its processability.
- The overall innovation of this patent application lies in the improved slurry composition that enables a more efficient and flexible manufacturing process for lithium secondary batteries.
Original Abstract Submitted
A slurry composition, and a positive electrode and a lithium secondary battery including the same are provided. The slurry composition includes a positive electrode active material, an electrically conductive material, a binder, a thickener comprising a lithiated carboxymethyl cellulose, an additive comprising a carbodiimide-based compound, and a solvent, and provides an improved processability in a slurry coating process for manufacturing a positive electrode for a lithium secondary battery due to its thixotropy by which sufficient flowability to flexibly respond to changes in slurry coating rate is secured.
