The invention aims to overcome the defects of the prior art and provide a preparation method of a composite polymer solid electrolyte, which can obviously improve the ionic conductivity, the mechanical strength and other properties of the polymer electrolyte and improve the properties of a solid lithium/sodium ion battery.
In order to achieve the purpose, the invention adopts aramid fiber as a modified material to prepare the aramid fiber/polymer matrix/lithium (sodium) salt composite solid electrolyte, and the specific technical scheme is as follows:
1) preparing a certain amount of aramid fiber and inorganic salt (such as potassium hydroxide and sodium hydroxide) in dimethyl sulfoxide, stirring for a period of time at a certain temperature to prepare an aramid nanofiber solution with good dispersibility, and then performing dialysis treatment to obtain an aramid nanofiber/dimethyl sulfoxide solution with high purity and good dispersibility; the aramid fiber is one or two of poly-p-phenylene terephthamide and poly-m-phenylene isophthalamide.
2) Adding a certain amount of the aramid nano-fiber solution into an organic solvent, continuously stirring for a period of time to completely disperse the solution, adding lithium/sodium salt and a polymer matrix material, and continuously stirring at a certain temperature to obtain an aramid nano-fiber/polymer matrix material/lithium (sodium) salt composite solution with good dispersibility; the polymer matrix material is one or more of polyethylene oxide, polyacrylonitrile, polycarbonate, polymethyl methacrylate, polyvinylidene fluoride and polyvinylidene fluoride-hexafluoropropylene, the lithium salt comprises one or more of lithium chloride, lithium perchlorate, lithium hexafluorophosphate, lithium bistrifluoromethylsulfonyl imide and lithium trifluoromethylsulfonyl imide, the sodium salt comprises one or more of sodium chloride, sodium perchlorate, sodium hexafluorophosphate, bistrifluoromethylsulfonyl imide and sodium trifluoromethylsulfonyl imide, and the organic solvent is one or more of acetonitrile, N-dimethylformamide, N-dimethylacetamide, dimethyl sulfoxide and N-methylpyrrolidone.
3) Treating the composite solution by a slurry coating method or a solution casting method, and drying the obtained composite gel film to obtain an aramid nano-fiber/polymer matrix/lithium (sodium) salt composite solid electrolyte film with a certain thickness; the content of the aramid fiber in the composite solid electrolyte is 0.1-40.0 wt%, and the content of the lithium/sodium salt in the composite solid electrolyte is 5.0-50.0 wt%.
