The application discloses a titanium-doped silicon-carbon negative electrode material and a preparation method thereof. The preparation method comprises the following steps: S100, mixing a carbon source, a titanium source and a pore-forming agent in water to obtain a first product containing titanium oxide through freeze-drying; S200, calcining the first product in a reducing gas to obtain Ti4O7-doped porous carbon; and S300, performing gas-phase deposition of a silane gas source and a carbon gas source on the outer surface and pores of the Ti4O7-doped porous carbon in an inert gas to obtain a silicon-carbon negative electrode material. The carbon source, the titanium source and the pore-forming agent are mixed in water to generate titanium oxide, and the titanium oxide is calcined by using a reducing gas, so that the titanium oxide is reduced into Ti4O7 with metallic conductivity and high catalytic activity, and the electron transmission is fast and the structure is stable. The silane gas source and the carbon gas source are gas-phase deposited on the Ti4O7-doped porous carbon to generate silicon-carbon active substances in situ, and the structural stability and the conductivity are improved.

This invention relates to the field of garment processing technology, specifically providing a drying device designed to solve the problem of lint filters often not being installed correctly. To address this, the drying device of this invention includes a drying duct and a lint filter. The drying duct has an insertion port, through which the lint filter is inserted. A blocking and positioning structure is located on the inner wall of the drying duct, away from the insertion port, and this structure abuts against the lint filter. By using the blocking and positioning structure within the drying duct, the user can push the lint filter forward along the duct until it abuts against the blocking and positioning structure, at which point it can no longer be pushed. This indicates that the lint filter has been installed in the designated position, thus preventing improper installation.
