The invention belongs to the field of lithium ion battery diaphragm materials and discloses modified silicon dioxide and a lithium ion battery polyolefin microporous diaphragm. The diaphragm is prepared by the following method: blending modified silicon dioxide with polyolefin having high / ultrahigh molecular weight, adding common polyolefin, and pelleting so as to obtain modified masterbatch; mixing the modified masterbatch with polyolefin and then carrying out melt blending and extrusion so as to form a diaphragm with a hard elastic structure; and carrying out continuous tension on the diaphragm, and then carrying out heat shaping at the temperature of 100-150 DEG C so as to obtain the lithium ion battery polyolefin microporous diaphragm. According to the invention, the thickness of the lithium ion battery polyolefin microporous diaphragm is relatively low (less than 15mu m); the strength of the diaphragm is better (the longitudinal breaking strength is larger than 100MPa, the transversal breaking strength is about 8MPa, and breaking elongation is 50%); the porosity and pore structure of the diaphragm are adjustable (the porosity is more than 50%, and the pore diameter is 0.1-1mum); and the thermal shrinkage factor of the diaphragm is smaller (less than 5%). According to the invention, the defect and lack of the existing dry preparation technology of the lithium ion battery diaphragm are overcome.

The invention relates to a porous membrane for a liquid flow battery and its preparation and application. The porous membrane is composed of one or more organic polymer resins and one or two organic or inorganic components degradable in electrolyte The above is prepared from raw materials; the content of degradable components is 5-40wt% of the mass of the organic polymer resin; and it is prepared under constant temperature and humidity conditions during the preparation process. This type of membrane has a multi-level porous structure, which can effectively realize the separation of ions in different valence states and maintain the ion permeation selectivity of the ion membrane of the membrane. This type of composite membrane has simple process, environmentally friendly process, controllable pore structure, low cost and easy mass production.
