SYSTEM AND METHOD FOR FABRICATING ELECTRODE FILM FOR SECONDARY BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 17524241 titled 'SYSTEM AND METHOD FOR FABRICATING ELECTRODE FILM FOR SECONDARY BATTERY
Simplified Explanation
The patent application describes a system for fabricating an electrode film for a secondary battery. The system includes three main units: a powder film fabrication unit, a base material film fabrication unit, and an electrode film fabrication unit.
- The powder film fabrication unit forms a mixture powder by combining active material powder, binder powder, and conductive material powder. It then fibrillates the mixture powder to create a powder film roll.
- The base material film fabrication unit forms a mixture solution by combining carbon-based powder, binder powder, and organic solvent. It patterns the mixture solution on a base material film to create a base material film roll.
- The electrode film fabrication unit places the base material film roll between two powder film rolls and bonds them together to create an electrode film roll.
Potential applications of this technology:
- This system can be used in the production of secondary batteries, such as lithium-ion batteries, which are widely used in various electronic devices.
- The electrode film fabrication process can be easily integrated into existing battery manufacturing processes, making it suitable for large-scale production.
Problems solved by this technology:
- The system simplifies the fabrication process of electrode films for secondary batteries by combining the formation of powder films and base material films into a single process.
- By using a mixture solution and fibrillating the mixture powder, the system ensures uniform distribution of active material, binder, and conductive material in the electrode film.
Benefits of this technology:
- The simplified fabrication process reduces production time and cost, making it more efficient for battery manufacturers.
- The uniform distribution of materials in the electrode film improves the overall performance and reliability of the secondary battery.
- The system can be easily integrated into existing battery manufacturing processes, minimizing the need for significant changes or investments in equipment.
