Embodiment 1
[0020] Example 1: Measuring the conductivity of electrolyte membranes made of different lithium-containing minerals at room temperature
[0021] Experimental group 1: Step 1): Weigh 0.5g of LiClO 4 , 1.0g of calcium fluoride and 1.5g of PEO powder, mixed into 50ml of acetonitrile, and stirred to obtain a uniform viscous solution.
[0022] Step 2): Put 1.0 g of spodumene into a QM planetary ball mill (produced by Shanghai Chubo Laboratory Equipment Co., Ltd.) for 1 hour, and the rotation speed of the rotor is 600 r / min. After grinding, weigh a small amount and measure its average particle size in a particle size analyzer. The average particle size of spodumene is less than 20 μm.
[0023] Step 3): Weigh 0.15g of ground spodumene, add 50ml of acetonitrile, 20-40kHz ultrasonic vibration for 15min, and stir evenly.
[0024] Step 4): Mix the mixture obtained in step 1) and step 3), stir until uniform, pour it into a polytetrafluoroethylene mold, place it at room temperature, and form a fil...
Embodiment 2
[0031] Step 1): Weigh 0.5g of LiClO 4 , 1.0g of calcium fluoride and 1g of PEO powder, mixed into 50ml of acetonitrile, and stirred to obtain a uniform viscous solution.
[0032] Step 2): Put 1.0 g of lithium permeate feldspar into a QM planetary ball mill (produced by Shanghai Chubo Laboratory Equipment Co., Ltd.) and grind for 1 hour, and the rotation speed of the rotor is 600 r / min. After grinding, weigh a small amount and measure its average particle size with a particle size analyzer. The average particle size of lapholite is less than 20 μm.
[0033] Step 3): Weigh 0.2g of the ground feldspar, add 50ml of acetonitrile, oscillate ultrasonically at 20-40kHz for 15min, and stir evenly.
[0034] Step 4): Mix the mixture obtained in step 1) and step 3), stir until uniform, pour it into a polytetrafluoroethylene mold, place it at room temperature, and form a film naturally. Then, it was dried in vacuum at 60°C for 24 hours to obtain a polymer electrolyte membrane.
Embodiment 3
[0036] Step 1): Weigh 0.5g of LiClO 4 , 1.0g of calcium fluoride and 2.5g of PEO powder, mixed into 50ml of acetonitrile, stirred to obtain a uniform viscous solution.
[0037] Step 2): Put 1.0 g of lepidolite into a QM planetary ball mill (produced by Shanghai Chubo Laboratory Equipment Co., Ltd.) for 1 hour, and the rotation speed of the rotor is 600 r / min. After grinding, weigh a small amount and measure its average particle size with a particle size analyzer. The average particle size of lepidolite is less than 20 μm.
[0038] Step 3): Weigh 0.17g of ground lepidolite, add 50ml of acetonitrile, 20-40kHz ultrasonic vibration for 15min, and stir evenly.
[0039] Step 4): Mix the mixture obtained in step 1) and step 3), stir until uniform, pour it into a polytetrafluoroethylene mold, place it at room temperature, and form a film naturally. Then, it was dried in vacuum at 60°C for 24 hours to obtain a polymer electrolyte membrane.
