If you can provide more details or clarify the context in which you encountered "200gana-906," I could offer a more targeted response.

– The Li‑Si‑Gr composite leverages a silicon‑nanowire scaffold (average length 150 nm) interwoven with few‑layer graphene sheets . Silicon supplies a theoretical capacity of 3 600 mAh·g⁻¹, but suffers from huge volumetric expansion (>300 %). GANA’s patented “elastic graphene matrix” accommodates this expansion, limiting particle pulverization and maintaining >95 % capacity after 2 500 cycles. 200gana-906
