Anode-less lithium metal batteries (ALLMB) are promising candidates for energy storage applications owing to high-energy-density and safety characteristics. However, the unstable solid electrolyte interphase (SEI) formed on anode copper current collector (CuCC) leads to poor reversibility of uneven lithium deposition/stripping. Though the well-known knowledge of lithium salt-derived inorganic-rich SEI (iSEI) benefiting uniform lithium deposition, how to design a lithium salt-philic CuCC with undiscovered salt-philic facet that favors lithium salt adsorption and catalyzing salt decomposition into iSEI, remains unexplored yet.

Herein, the co-doping of the highest electronegative fluorine (F) and large atomic radius chlorine (Cl) into G via a one-step electrochemical exfoliation protocol is engineered to actualize the ultralong cycling stability for flexible micro-supercapacitors (MSCs). Density functional theoretical calculations unveiled that the F into G can form the "ionic" C─F bond to increase the repulsive force between nanosheets, and the introduction of Cl can enlarge the layer spacing of G as well as increase active sites by accumulating the charge on pore defects.

The introduction of sulfur (S) into nickel molybdate (NiMoO) at room temperature leads to the formation of sulfur-doped NiMoO (S-NiMoO), thereby significantly enhancing the conductivity and facilitating electron transfer in NiMoO. Furthermore, the introduction of S effectively modulates the electron density state of NiMoO and facilitates the formation of highly active catalytic sites characterized by a significantly reduced hydrogen absorption Gibbs free energy (ΔG) value of -0.
