METHOD FOR MANUFACTURING NON-AQUEOUS SECONDARY BATTERY ELECTRODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240332484 titled 'METHOD FOR MANUFACTURING NON-AQUEOUS SECONDARY BATTERY ELECTRODE
The patent application describes a method for manufacturing a non-aqueous secondary battery electrode with improved bonding between the positive electrode layer and a solid electrolyte layer.
- Preparation of a positive electrode layer solution containing a positive electrode active material, binder, and a first solvent.
- Formation of a positive electrode layer using the positive electrode layer solution.
- Formation of an electrolyte layer containing a solid electrolyte.
- Preparation of an adhesive layer solution containing a solid electrolyte and a second solvent.
- Formation of an adhesive layer using the adhesive layer solution.
- Stacking of the positive electrode layer, adhesive layer, and electrolyte layer in sequence, with the second solvent having higher solubility for the binder than the first solvent.
Potential Applications: - Manufacturing of non-aqueous secondary batteries with improved electrode structure. - Energy storage systems for various electronic devices.
Problems Solved: - Enhancing the bonding between the positive electrode layer and solid electrolyte layer. - Improving the overall performance and reliability of non-aqueous secondary batteries.
