Chemical and mechanical degradation at the contact point between solid-state components leads to high impedance and cell failure. Mitigating these surface-level irregularities ensures stable ion transport and prevents premature battery death.

Uncontrolled sebum production leads to skin conditions and aesthetic concerns. Regulating this secretion improves dermatological health and product efficacy.

Variations in precursor ratios lead to poor electrochemical reproducibility and capacity loss. Precise control over composition prevents phase impurities and ensures structural stability during cycling.
