Thermal tab encapsulation assembly: BYDRecent Research Landscape

Inconsistent thermal contact during soft-pack encapsulation leads to electrolyte leakage and cell failure. Precise mechanical control of the sealing interface ensures hermetic integrity and prevents thermal degradation of the laminate.

What technical problems is BYD addressing in Thermal tab encapsulation assembly?

Electrode core positioning inaccuracy

(17)evidences

Misalignment during cell stacking and casing insertion causes internal short circuits or non-uniform pressure distribution. Precise spatial control prevents mechanical stress and electrochemical failure.

Inconsistent electrode tab alignment

(16)evidences

Mechanical misalignment during folding and insufficient thermal bonding of cell tabs lead to structural failure or electrolyte leakage. Precise positioning and thermal integration prevent internal shorts and ensure hermetic integrity.

Electrical connection integrity failure

(15)evidences

Mechanical instability or misalignment during the tab assembly process leads to intermittent electrical contact or structural failure. Ensuring connection integrity prevents device malfunction and manufacturing defects.
