| titleOfInvention | A kind of modification method of polyolefin lithium ion battery separator |
| abstract | A method for modifying a polyolefin lithium ion battery separator belongs to the field of lithium ion battery separators. The pretreated polyolefin separator in step 1) is immersed in a polycationic electrolyte solution containing calcium salt, and after 10 to 100 minutes, it is taken out and washed, and then immersed in a polyanionic electrolyte solution containing sodium silicate for 10 to 100 minutes. In this way, While the polycation electrolyte and the polyanion electrolyte are assembled by electrostatic interaction, the Ca 2+ in the calcium salt reacts in situ with the SiO 3 2~ ions of the sodium silicate to generate calcium silicate inorganic nanoparticles in the polyelectrolyte; repeat In the steps of 1 to 6 times, organic/inorganic hybrid composite layers with different numbers of assembled layers are constructed on the surface of the polyolefin porous membrane; and then it can be dried. The separator has good thermal stability and charge-discharge stability. |
