Embodiment 1
[0031] use MoS 2 As the positive active material, the positive plate is assembled according to MoS 2 : The mass ratio of platinum slurry is 70:30 and mixed evenly, then evenly spread the gel on the molybdenum sheet of 10mm×20mm, and finally put it in an oven at 60-120 degrees Celsius for more than 12 hours and dry it with GF / The D separator material is wrapped as the positive electrode of the battery. The negative electrode is high-purity aluminum, which is soaked in absolute ethanol for 1-2 hours, dried by ultrasonic vibration, and then cut into a sheet of 10mm×20mm as the negative electrode. Anhydrous aluminum chloride and 1-ethyl-3-methylimidazolium chloride are formulated into an ionic liquid in a glove box in an argon atmosphere at a mass ratio of 1.3:1, as an electrolyte for an aluminum ion battery of the present invention. Finally, the prepared positive electrode, negative electrode and electrolyte were assembled into a battery in the glove box. After the battery is...
Embodiment 2
[0033] use MoS 2 As the positive electrode active material, it is mixed with the conductive material Super-P and the binder polytetrafluoroethylene (PTFE) at a mass ratio of 75:15:10, added to absolute ethanol for dispersion, and ultrasonically Shake for 20-30 minutes and mix evenly, then put it in an oven at 60 degrees Celsius and bake until it becomes gel, then spread the gel evenly on a molybdenum sheet of 10mm×20mm, and finally put it in an oven at 60-120 degrees Celsius for more than 12 hours to bake After drying, wrap it with GF / D diaphragm material as the positive electrode of the battery. The negative electrode is high-purity aluminum, which is soaked in absolute ethanol for 1-2 hours, dried by ultrasonic vibration, and then cut into a sheet of 10mm×20mm as the negative electrode. Anhydrous aluminum chloride and 1-ethyl-3-methylimidazolium chloride are formulated into an ionic liquid in a glove box in an argon atmosphere at a mass ratio of 1.3:1, as an electrolyte for...
