This invention relates to the field of sodium-ion battery technology, specifically to a modified hard carbon material and its preparation method, a negative electrode sheet, and a sodium-ion battery. The modified hard carbon material is obtained by mixing and grinding a hard carbon precursor with naphthalene at a mass ratio of 5-9:1-5, followed by a two-stage heat treatment. This invention utilizes the gas-phase infiltration and high-temperature carbonization of naphthalene at specific temperatures. In the first stage, naphthalene is converted into gaseous molecules. Its small kinetic diameter allows it to penetrate deep into the micropores of the hard carbon precursor and be adsorbed under capillary action and pressure difference. In the second stage, naphthalene undergoes pyrolysis, transforming in situ into an amorphous soft carbon layer. This achieves uniform and deep filling of carbon within the micropores of the hard carbon, effectively reducing the average pore size. This not only promotes the pre-desolvation of solvated sodium ions but also helps to obtain an ultrathin and stable NaF-rich solid electrolyte interface film, improving the rate performance of the material. Furthermore, this process is simple, efficient, and low-cost, which is beneficial for large-scale production.

This invention discloses a thin-film solar cell with synergistic passivation and field-effect modulation functions, and its fabrication method, belonging to the field of solar cell technology. The core of this invention lies in introducing an ultrathin barium titanate (BaTiO3) interlayer between the back electrode and the CZTSSe absorber layer. This interlayer not only passively blocks electron backflow and suppresses interfacial recombination by utilizing its large conduction band offset with CZTSSe, but more importantly, it can induce BaTiO3 absorption during high-temperature selenization. 2+ Cu in CZTSSe + Non-equivalent cation migration and exchange occur, thereby actively constructing a directionally favorable cation migration and exchange-induced built-in electric field (CME-field) within the quasi-neutral region of the absorber layer, synergistically promoting the collection of photogenerated holes. This invention achieves a synergistic effect of "passive blocking" and "active driving," significantly improving battery performance and increasing the photoelectric conversion efficiency of battery devices to 14.00%.
