Initial investigations explore the adsorption of lithium(Li)/sodium(Na)/magnesium(Mg) ions and their diffusion on α-Te anode. The Li-ion showed higher adsorption energy (−2.21 eV) compared to Na and Mg ions. The diffusion barrier of Li and Na is found to be 0.23 and 0.17 eV, respectively, compared to the Mg ion (0.53 eV). To understand the electrolyte–electrode interface characteristics, Li salt electrolytes with bis(fluorosulfonyl) imide (FSI) and bis-trifluoromethane sulfonyl imide (TFSI) anions are made to interact in parallel and perpendicular orientations with the surface of the α-Te anode. The adsorption of both FSI and TFSI anions is energetically favorable, and it induces a semiconductor-to-metal transition in the anode. Furthermore, the AIMD study on Li⁺ integrated FSI/TFSI anions with α-Te was performed to understand the structural and dynamical parameters including the radial distribution function (RDF), diffusivity, etc. The α-Te monolayer has retained its structural integrity throughout the simulations. The RDF plots confirm that the oxygen of FSI and TFSI are more aggregating around the Li ions forming the solvation shell that initiates ion migration. Also, the pathway of Li⁺ ion migration through the anions involves both vehicular and structural diffusion mechanisms. The self-diffusion coefficient of Li-ion is calculated as 4.48 × 10^–9 m²/s and 3.05 × 10^–9 m²/s in FSI and TFSI systems, respectively.

Therefore, a conductive carbon nanofiber host with a directed gradient pore structure is reported in this work (signed as GPCF), based on two carbon nanofiber networks with both a small pore size (∼2.6 μm) as the current collector side and a large pore size (∼3.9 μm) facing the separator side. As a result, the uniform lithium-ion flow with a small ion concentration gradient from the separator to the current collector side is formed within GPCF, to enable the dendrite-free lithium deposition morphology. The GPCF anode can run for more than 160 cycles at 0.5 mA cm^–2 and 1 mAh cm^–2, and the Coulombic efficiency is up to 99%. In contrast, the carbon nanofiber hosts with only small, large, or inverse gradient pore size structures easily form significant “dead Li” after 80, 120, and 100 cycles, respectively, and the Coulombic efficiency fluctuates severely.
