Polymeric dielectric isolation coatings: BYDRecent Research Landscape

Mechanical failure during high-speed film tearing and application increases cell internal resistance and scrap rates. Engineering the structural integrity and surface adhesion of the protective layers ensures consistent battery electrode isolation.

What technical problems is BYD addressing in Polymeric dielectric isolation coatings?

Inconsistent battery case insulation

(34)evidences

Inadequate dielectric barriers between cells and modules lead to short circuits and thermal runaway. Robust isolation prevents catastrophic electrical breakdown in high-voltage vehicle environments.

Intercell electrical short circuiting

(20)evidences

Structural failure or misalignment of electrical tabs during assembly and operation. Preventing these defects ensures electrical continuity and prevents internal short circuits.
