Embodiment 1
[0040] The application provides the preparation method of the first non-woven paper ion battery diaphragm, and the specific steps are as follows:
[0041] At first the barium titanate 1g that particle diameter is 50nm joins in the acetone (100ml) and disperses uniformly, behind 1,4-butanediol and hexachlorocyclotriphosphazene (1,4-butanediol and hexachlorocyclotriphosphazene The molar ratio is 3:2) were added to acetone containing barium titanate, and reacted, the reaction conditions were 60 ° C stirring reaction for 4 hours, centrifuged to wash off the solvent and 80 ° C blast drying for 2 hours to obtain modified barium titanate powder ; Add modified barium titanate powder, sodium tripolyphosphate (0.1g), sodium lauryl sulfate (0.1g) to the DMSO solution of polyvinylidene fluoride PVDF (PVDF is 1g, DMSO is 50ml) and compounded Slurry and mix uniformly to obtain coating slurry.
[0042] The obtained coating slurry is coated on the surface of the non-woven paper, dried and th...

[0045] The application provides the second preparation method of non-woven paper ion battery separator, the specific steps are as follows:
[0046] At first the barium titanate 1g that particle diameter is 50nm joins in the acetone (100ml) and disperses uniformly, behind 1,4-butanediol and hexachlorocyclotriphosphazene (1,4-butanediol and hexachlorocyclotriphosphazene The molar ratio is 3:2) were added to acetone containing barium titanate, and reacted, the reaction conditions were 60 ° C stirring reaction for 4 hours, centrifuged to wash off the solvent and 80 ° C blast drying for 2 hours to obtain modified barium titanate powder ; Add modified barium titanate powder, sodium tripolyphosphate (0.1g), sodium lauryl sulfate (0.1g) to the DMSO solution of polyvinylidene fluoride PVDF (PVDF is 1g, DMSO is 50ml) and compounded Slurry and mix uniformly to obtain coating slurry.
[0047] The obtained coating slurry is coated on the surface of the non-woven paper, dried and then hot-...
Embodiment 3
[0049] The application provides the third preparation method of the non-woven paper ion battery separator, the specific steps are as follows:
[0050] At first the barium titanate 1g that particle diameter is 50nm joins in the acetone (100ml) and disperses uniformly, behind 1,4-butanediol and hexachlorocyclotriphosphazene (1,4-butanediol and hexachlorocyclotriphosphazene The molar ratio is 3:2) were added to acetone containing barium titanate, and reacted, the reaction conditions were 60 ° C stirring reaction for 4 hours, centrifuged to wash off the solvent and 80 ° C blast drying for 2 hours to obtain modified barium titanate powder ; Add modified barium titanate powder, sodium tripolyphosphate (0.1g), sodium lauryl sulfate (0.1g) to the DMSO solution of polyvinylidene fluoride PVDF (PVDF is 1g, DMSO is 50ml) and compounded Slurry and mix uniformly to obtain coating slurry.
[0051] The obtained coating slurry is coated on the surface of the non-woven paper, dried and then h...
