Inadequate sealing at the interface where electrical leads penetrate the battery housing. Preventing electrolyte leakage and moisture ingress ensures long-term electrochemical stability.

Mechanical stress and electrolyte leakage at the tab-to-cover interface compromise cell longevity. Ensuring a robust seal prevents premature battery failure and environmental contamination.

Mechanical failure or leakage at the interface between internal components and external packaging. Ensuring robust containment prevents environmental contamination and internal short circuits.
