Making process of lithium ion battery porous carrier

The invention discloses a making process of a lithium ion battery porous carrier, the specific surface area of the raw material of the porous carrier is greater than or equal to 1000m / g, the carbon tetrachloride adsorption value is greater than or equal to 50%, the phenol adsorption value is greater than or equal to 11mL, the particle size of the porous carrier is 20-45 mesh, the porous carrier is activated carbon and molecular sieve or a mixture of the activated carbon and the molecular sieve, the lithium ion battery porous carrier is prepared by a specific process, the porous carrier material prepared by the making process has the characteristics of strong adsorption capacity and stable surface functional group performance, after the porous carrier material is put into a lithium battery material groove, the test shows that the performance is excellent, excess gases generated in a lithium battery can be effectively absorbed, and the lithium battery performance and life are greatly improved.
