Pouch cell structural reinforcement: BYDRecent Research Landscape

Mechanical failure of cell housings during thermal expansion leads to internal short circuits and pack degradation. This lever stabilizes the electrode core through rigid lateral containment to extend cycle life.

What technical problems is BYD addressing in Pouch cell structural reinforcement?

Mechanical deformation under internal pressure

(73)evidences

Pouch cells lack inherent rigid housing, making them vulnerable to deformation and internal damage during assembly or vehicle operation. Addressing this prevents cell displacement and catastrophic failure in high-vibration environments.

Structural instability under mechanical stress

(41)evidences

Pouch cells lack inherent rigid housing and are prone to shifting or deformation during vehicle operation. Preventing mechanical displacement ensures electrical contact integrity and prevents internal short circuits.

Structural vulnerability to external impact

(35)evidences

Mechanical deformation and casing breach during collision or vibration. Enhancing structural integrity prevents thermal runaway and internal component failure.

Structural casing deformation

(30)evidences

Standard pouch cell enclosures lack sufficient structural rigidity to protect internal components from physical deformation or puncture. Mitigating this vulnerability prevents thermal runaway and ensures long-term structural integrity in mobile applications.
