Adhesive polymer separator coating: BYDRecent Research Landscape

Internal resistance and electrode delamination cause premature battery failure and safety risks. Engineering the adhesive interface between the separator and electrode ensures mechanical stability and consistent ion transport.

What technical problems is BYD addressing in Adhesive polymer separator coating?

Internal short circuit risk

(45)evidences

Weak mechanical bonding between the separator and electrodes leads to internal shifting and cell swelling. Improving adhesion prevents structural instability and internal short circuits during cycling.

Electrode component adhesion failure

(11)evidences

Weak mechanical bonding between electrode active materials and current collectors leads to delamination during cycling. Enhancing structural integrity prevents capacity loss and internal resistance increases.
