[0034] The preparation of carbon nanotube sodium superionic conductor comprises the following steps:
[0035] Step 1: Under high pressure, the flowing carbon nanotube liquid is collided with ultra-high pressure for 15-30 minutes to form a uniform and stable carbon nanotube dispersion;
[0036] Step 2: uniformly stir and mix the sodium superionic conductor, carbon nanotube dispersion and dispersant in the solvent N-methylpyrrolidone for 4-6 hours to obtain the first mixed solution; the reason for the formation of the superionic conductor is the non- The conductive ions form a rigid skeleton, and there are more occupyable positions than the number of conductive ions inside the crystal lattice. Free movement, the material has excellent comprehensive properties, high room temperature ionic conductivity, good thermal stability, and LiCoO 2 , LiMn 2 o 4 Positive electrodes such as metal lithium, lithium alloy and other negative electrodes have good compatibility, and carbon nanot...
