Embodiment 1
[0021] Material preparation: The average molecular weight of 300,000 polyethylene oxide and tributylmiammonium chloride and tributylmmonium chloride were 20%: 20%: 60%: 60% in a 20 ml reagent bottle, add 3 ml Anhydrous acetonitrile was stirred on a magnetic stirrer for 48 h, and then placed in a polytetrafluoroethylene plate, and the solution was gently scraped on the plate with a scraper having a thickness, volatilized under a nitrogen atmosphere and normal pressure. The vacuum drying tank was vacuum dry at 50 ° C for 48 h, i.e., a film which was controlled at a certain uniform thickness was obtained, and the rear shielded a circular wafer to be used.
[0022] Optical photograph analysis figure 1 A, b): The mechanical properties of the fully solid-state polymer electrolyte membrane are good, bendable), is a translucent film; electron microscope photos ( figure 1 C) The analysis showed that the film had a thickness of about 80 μm.

Embodiment 2
[0027]Material preparation and electrochemical performance test: polyethylene molecular oxide, 1-methyl-4-butylpiperidinium salt, and nano-titanium oxide at an average molecular weight of 150,000: 32%: 3% The ratio was placed in a 20 ml reagent bottle, and 5 ml of anhydrous acetic acetonitrile was added, and stirred at a magnetic stirrer at a rotational speed of 450 rpm for 72 h, then placed in a polytetrafluoride plate, and gently scrape it on the plate with a scraper with a thickness. The ventilation wardrobe is volatilized for 3 h and dried in vacuo at 40 ° C, that is, a film controlled at a certain uniform thickness is obtained, and the full solid polymer electrolyte film is punched into a 19 mm rounded and transferred to an inert atmosphere. use. The polypyrrol is used as a positive electrode, and the metal lithium is a negative electrode assembly full solid-state rechargeable chloride battery, and the circulating test is performed at 313K at a current density of 10 mA / g.

[0029] Material Preparation and Electrochemical Performance Test: Polycyclopropane and 1-methyl-4 butylpyrrolidine salt of the average molecular weight of 300,000, aluminum oxide in mass ratio of 70%: 15%: 15% In a 20 ml reagent bottle, 5 ml of methanol was dissolved, and stirred at a magnetic stirrer for 72 h on a magnetic stirrer, then placed in a polytetrafluoroide plate, and gently scrape it on the plate with a scraper having a thickness, in a nitrogen atmosphere And at normal pressure, 3-6 h was evaporated and dried in vacuo at 60 ° C. Place it in the box. The chloride is used as the positive electrode, and the metal magnesium / carbon composite is an negative electrode assembly full solid chloride ion battery, and the circulating test is performed at 313 K at a current density of 10 mA / g. The first discharge ratio can reach 55 mAh / g.
