Novel Anode Active Material Slurry For Coating An Anode Current Collector For A Secondary Li-Ion Battery
Patent No. EP4483428 (titled "Novel Anode Active Material Slurry For Coating An Anode Current Collector For A Secondary Li-Ion Battery") was filed by Trinseo Europe on Jun 27, 2023. The application was issued on Feb 12, 2025.
Patent Summary
An anode active material slurry for coating an anode current collector in secondary Li-ion batteries, comprising an alkali-swellable emulsion with hydrophobic alkyl groups. The slurry provides superior adhesion and electrical performance compared to conventional thickening agents like carboxymethyl cellulose, while maintaining the slurry's dispersion properties. The emulsion-based thickener enables uniform coating of the anode current collector, even during electrode slitting, without compromising the slurry's properties.
