Aluminum foil surface morphology: BYDRecent Research Landscape

Interfacial resistance and mechanical failure at the current collector reduce cycle life and energy density. These innovations engineer the surface structure and metallurgical properties of aluminum foils to ensure stable electrochemical contact.

What technical problems is BYD addressing in Aluminum foil surface morphology?

Interfacial contact resistance

(28)evidences

Poor adhesion and high impedance at the current collector interface cause power loss and capacity fade. Reducing this resistance improves charge transfer efficiency and cycle life.

Electrode interface adhesion failure

(18)evidences

Poor adhesion and structural failure between the current collector and active material layers. Mitigating this interface degradation prevents delamination and internal resistance spikes in high-density battery cells.
