Composite silicon carbon anode architecture: BYDRecent Research Landscape

Volume expansion during lithiation causes mechanical fracture and rapid capacity loss in high-energy anodes. Engineering the silicon-carbon composite structure mitigates mechanical stress to extend battery cycle life.

What technical problems is BYD addressing in Composite silicon carbon anode architecture?

Anode structural instability

(143)evidences

Silicon-based anodes suffer from extreme volumetric expansion during lithiation, leading to pulverization and loss of electrical contact. Addressing this mechanical failure is essential for maintaining cycle life and structural integrity in high-capacity batteries.

Interfacial contact loss

(34)evidences

Mechanical strain and volume changes during cycling cause physical separation between solid components. Maintaining continuous ionic and electronic pathways is necessary to prevent rapid capacity decay.
