Example Embodiment
[0036] Example 1
[0037] (1) Disperse 200 mg of silicon nanoparticles into 400 mL of ethanol / water mixed solution, where the volume ratio of ethanol to water is 4:1 (V:V). Add 4.0 mL of concentrated ammonia and 2.0 g of ethyl orthosilicate to the mixed solution dropwise. The mixed solution was stirred at room temperature for 12 hours, then centrifuged, washed with ethanol 3 times, and dried at 80°C to obtain Si@SiO with a core-shell structure 2 Particles.
[0038] (2) Use an electronic balance to weigh 0.2g Ping Ping plus O and dissolve it in 5 g of N-N dimethylformamide, place it in a 20 mL sample bottle, and heat and stir at 60°C until it is completely dissolved. Then use a balance to weigh 0.2 g Si@SiO 2 , 0.4g polyacrylonitrile was dissolved in the mixed solution, the sample bottle was sealed with a sealing film, stirred at 60°C for 24 hours, and ultrasonically dispersed at room temperature for 1 hour to obtain a uniformly dispersed spinning solution. Cut out 40 cm×40 cm alu...

[0043] Example 2
[0044] (1) Disperse 200 mg of silicon nanoparticles into 400 mL of ethanol / water mixed solution, where the volume ratio of ethanol to water is 4:1 (V:V). Add 4.0 mL of concentrated ammonia and 2.0 g of ethyl orthosilicate to the mixed solution dropwise. The mixed solution was stirred at room temperature for 12 h, then centrifuged, washed with ethanol 3 times, and dried at 80°C to obtain Si@SiO2 particles with a core-shell structure.
[0045] (2) Use an electronic balance to weigh 0.2 g of Ping Ping plus O and dissolve it in 5 g of N-N dimethylformamide, place it in a 20 mL sample bottle, and heat and stir at 60°C until it is completely dissolved. Then weigh 0.2 g of Si@SiO2 and 0.4 g of polyacrylonitrile in the mixed solution with a balance. The sample bottle was sealed with a sealing film, stirred at 60°C for 24 hours, and ultrasonically dispersed at room temperature for 1 hour to obtain a uniformly dispersed spinning solution. Cut out 40 cm×40 cm aluminum foi...
