2.3.2. Preparation of modified diaphragm According to the proportion of the same active material, conductive carbon, and PDVF at 8:1:1, the prepared activated material was uniformly coated on the surface of the diaphragm and dried in a vacuum oven at 60°C for 10h to obtain a modified diaphragm.
At the same time, the smaller the contact angle of the electrolyte on the diaphragm, the better the wettability of the electrolyte. The wetting angles of the diaphragm, HC modified diaphragm and AHC modified diaphragm are 32°, 25°, and 11°, respectively.
Based on the above advantages, the AHC-modified diaphragm prepared from hazelnut shell biomass carbon material not only retains the original performance of the diaphragm but also has the ability of physical barrier and chemical adsorption of polysulfides, which greatly reduces the shuttle effect.
