Nanosecond pulse laser-induced rapid construction of Bi-doped porous graphite carbon for expanding the range of lithiophilic host

In the traditional process, the conversion of metal-organic frameworks (MOFs) into carbon materials requires higher temperatures, longer preparation time, and an inert atmosphere. Herein, we report a fast and convenient nanosecond pulse laser-induced carbonization strategy to rapidly prepare MOFs-derived Bi-doped porous graphite carbon materials (LIC-Bi-MOF) in one step at room temperature and air atmosphere. During the prelithiation stage, the Li3Bi alloy formed by the reaction of Bi and Li can provide abundant Li nucleation sites and significantly reduce the overpotential of Li nucleation, thus inducing uniform nucleation and deposition of Li. The porous structure formed at the same time can provide channels for the transmission of ions and electrons and can adapt to the volume change during repeated lithium plating/stripping processes. Consequently, the symmetrical battery with LIC-Bi-MOF@Li electrode can work at a stable overpotential (∼12 mV) for 2400 h at 2 mA cm−2. In particular, a full cell with LiFePO4 cathode provides a good capacity retention of 82.52 % at 8 C after 3500 cycles. These exceptional qualities present a novel conceptual framework for fabricating stable and dendrite-free lithium hosts through a laser-induced carbonization approach, opening avenues for the practical application of secure and durable Lithium metal batteries (LMBs). •A nanosecond laser-induced carbonization strategy is used.•Bi nanoparticles can be formed by laser irradiation.•Porous graphite carbon can be formed by laser irradiation.•Li3Bi formed by the reaction of Bi and Li can provide a uniform Li nucleation site.•Porous graphite carbon promotes the transfer of electrons and ions.
