A novel fabrication process for preparing high-density polyethylene (HDPE) based carbon fibre cloths (CFCs) containing microporous structures is developed by using conventional melt spinning, special weaving technique, electron radiation treatment and further the carbonization. For this purpose, the new developed HDPE GX5052 (LyondellBasell, ρ_PE=0.963 g⁄cm^3 , Mn=10.000 and Mw=70.000 g/mol) were melt spun as textile filaments (T_t=110 dtex f72, σ=35.1 cN/tex, ε=22.2 %) with a diameter of 14 µm each. The melt spun fibres were woven into fabrics that have plain and twill weave structures in 10 cm width. These fabrics were then treated with electron beam radiation at a room temperature under oxygen and nitrogen atmosphare at the IPF Dresden e. V. The woven fabrics were stabilized with H2SO4 98 % at 100 °C for 2 h and carbonizied at 800 °C for 10 min using a special carbonisation oven at ITM. The obtained HDPE-based CFCs exhibit a thickness of around 100 µm with a special microporous structures. These HDPE-based CFCs are therefore promising candiates as cathodes for lithium-sulfur (Li-S) batteries as high-performance cathodes lithium-sulfur (Li-S) batteries.
