Silicon carbon composite electrode architecture: BYDRecent Research Landscape

Volume expansion during lithiation causes mechanical fracture and rapid capacity loss in high-capacity anodes. Engineering the carbon-silicon interface and morphology stabilizes the composite structure to extend cycle life.

What technical problems is BYD addressing in Silicon carbon composite electrode architecture?

Electrode mechanical instability

(135)evidences

Silicon-based anodes suffer from severe structural disintegration during lithiation cycles. Mitigating this physical degradation prevents capacity loss and short cycle life.

Interfacial contact loss

(27)evidences

High volume expansion in silicon anodes and rigid solid electrolytes leads to mechanical disconnection at the electrode-electrolyte interface. Maintaining physical contact ensures continuous ion and electron transport during cycling.
