TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The continuous inorganic coating comprises oxides of silicon, zinc, zirconium, tin, titanium, barium and/or aluminum. The continuous inorganic coating has a thickness of 1-500 mm. The continuous inorganic coating on the surfaces of the pores within the porous material reaches a depth of 0.01-20 mu m. The carrier gas comprises nitrogen, argon, helium, oxygen, air and/or hydrogen. The coating gas comprises vapor or mist of silicon, zinc, zirconium, tin, titanium, barium and/or aluminum, preferably the coating gas comprises vapor or mist of tetraethoxysilane, tetramethoxysilane, hexamethyldisiloxane, hexamethyldisilazane, aluminum butoxide, diethylzinc, triethylaluminum, trimethylaluminum, metal alkyl, titanium tetraisopropoxide, titanium tetrapropoxide, metal alkoxide, zinc nitrate, aluminum nitrate, metal nitrate, zinc acetate, aluminum nitrate, tin acetate, metal acetate, zinc sulfate, aluminum sulfate, tin sulfate, metal sulfate, zinc chloride, zirconium chloride, aluminum chloride, titanium chloride and/or metal chloride.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The porous material comprises: polyethylene, polypropylene, polyethylene terephthalate, polyvinylidene fluoride, PTFE, polyacrylonitrile, polyimide, polyamide, polyester and/or natural fiber. The porous material has a thickness of 5-80 mu m, and a porosity of 40-75%. In the hybrid porous material, the surfaces of the pores within the porous material are completely covered by the continuous inorganic coating, or partially covered by the continuous inorganic coating. Preferred Method: The dry coating process is a plasma coating process, where the dry coating process uses a carrier gas and a coating gas. EXAMPLE - Porous separator having a tri-layer structure comprising polypropylene was subjected to a coating process. Hexamethyldisiloxane (HMDSO) was placed in a gas washing bottle and heated to 30 degrees C, then the plasma coating process was performed at an operating pressure of 1 atmosphere, a helium flow of 4.91 l/minute, a HMDSO steam flow of 2 sccm was carried by helium, an RF power of 90W, a coating period of 15 seconds, and a sample-electrode spacing of 2.1 mm, to obtain a hybrid porous material.
