Laser‑Driven Single‑Step Synthesis of Monolithic Prelithiated Silicon‑Graphene Anodes for Ultrahigh‑Performance Zero‑Decay Lithium‑Ion Batteries (IMAGE)
Caption
- We report an ambient single-step laser-driven process that simultaneously synthesizes and integrates prelithiated silicon nanoparticles into a robust graphene matrix using simple precursors.
- Prelithiation is achieved in situ through interfacial solid-state reactions between Si and common lithium salt precursors during the ultrafast photothermal graphitization of phenolic resin.
- Prelithiated silicon nanoparticles/laser-induced graphene anodes exhibit exceptional cycling stability (> 98% capacity retention after 2000 cycles) and near-zero performance decay in Li-ion half and full cells compared to non-lithiated counterparts.
