Invention Reference Number
This invention enhances the mechanical, electrical, and electrochemical properties of dry-processed battery electrodes by modifying precursor composition. By increasing the durability and conductivity of electrodes, this technology promotes eco-friendly, solvent-free electrode production for battery manufacturing and reduces manufacturing costs.
Description
In traditional electrode manufacturing, toxic solvents are required to create electrode slurries, which are then dried—an energy-intensive process that leaves toxic byproducts. This new approach, known as dry processing, combines active materials with binders without solvents, yielding dry electrode sheets. However, these dry-processed electrodes tend to be brittle and have low electrical conductivity. The invention addresses these weaknesses by modifying the mixture composition, which boosts both mechanical strength and conductivity. This method allows for the production of stronger, eco-friendly electrodes suitable for demanding applications like electric vehicles and stationary energy storage systems
