A Modified Water Soluble Binder for Graphite Anode in Li-Ion Battery: Towards a Better Binding Performance
However, because of the rigidness of the PMAA polymer, the electrodes go through delamination during production process. We modified the PMAA polymer structure, while maintaining the water solubility, change it to a flexible material. Peel tests show that the graphite laminates using the modified-PMAA material have better binding performance compared to PMAA polymer. Further gain includes improvement of the electrolyte uptake property and improved cell performance for graphite half cells.
