Microporous polymeric separator architecture: BYDRecent Research Landscape

Internal short circuits and thermal runaway risks increase as battery energy density rises. Engineering the physical pore structure and thermal shutdown properties of the separator mitigates these safety hazards.

What technical problems is BYD addressing in Microporous polymeric separator architecture?

Internal short circuit risk

(24)evidences

Weak physical bonding between electrode plates and separators causes mechanical instability and internal resistance. Enhancing interfacial integrity prevents delamination and improves battery cycle life.

Inaccurate internal potential measurement

(23)evidences

Electrochemical instability and signal drift in reference electrodes prevent precise monitoring of internal cell states. Reliable potential tracking is necessary to prevent hazardous conditions like lithium plating or dendrite growth.
