AI Technical Summary
During the continuous coating process of wide-width electrode sheets for power batteries, the edge effect causes uneven lateral distribution of coating thickness. Existing technologies cannot achieve globally optimal current distribution and uniform coating thickness, resulting in current crosstalk and control lag issues.
By setting up multiple independently controlled power supply zones, combined with insulating shielding plates and flexible conductive contacts, a singular value decomposition decoupling algorithm is used to obtain the effective current density. A long short-term memory network prediction model with attention mechanism is constructed, and combined with incremental fine-tuning and elastic weight consolidation regularization, multi-objective optimization and rolling time-domain closed-loop control are achieved.
It effectively suppresses edge effects, achieves lateral consistency and longitudinal stability of coating thickness, improves the areal density uniformity of coating thickness, and enhances the control precision and robustness of the coating process.
