Claim 9:
10. The method according to claim 8, wherein the method comprises preparation of the porous composite material by a method comprising the following steps:
(1) immersing the inorganic porous framework or inorganic porous framework precursor into a solution or dispersion of the carbon material and/or carbon material precursor, so that pores of the inorganic porous framework or inorganic porous framework precursor are filled with the solution or dispersion;
(2) heating and drying the porous material obtained in step (1), so that the carbon material or the carbon material precursor is precipitated or solidified and supported on the inorganic porous framework or the inorganic porous framework precursor;
(3) further performing the following step when at least one of the carbon material precursor or the inorganic porous framework precursor is used as a starting material: heating the porous material obtained in step (2) under an inert gas atmosphere to convert the inorganic porous framework precursor into an inorganic porous framework, and/or reducing or carbonizing the carbon material precursor.
