INTERLAYER MATERIAL FOR LITHIUM-SULFUR BATTERY, AND LITHIUM-SULFUR BATTERY
An interlayer material for a lithium-sulfur battery, and a lithium-sulfur battery, the interlayer material including electrically conductive MOF modified carbon fiber paper material between the separator and cathode accelerating electron transfer and having catalytic and barrier effect on lithium polysulfides. The paper material is prepared by: pretreatment of the paper by subjecting the carbon fiber paper to hydrophilic treatment; preparation of carbon fiber paper grown with Co.sub.3(HITP).sub.2 including: complexing Co.sup.2+ and hexaiminotriphenylene on the paper surface, and allowing the product to grow in situ; and removal of structural impurities. The carbon fiber paper provides an electrically conductive substrate ensuring high-speed electrode movement between the cathode and separator; and Co.sub.3(HITP).sub.2 grown on the carbon fiber paper provides sufficient polarity for the adsorption of lithium polysulfides, alleviating the shortcomings of the carbon material, and promotes a lithium polysulfides reaction through the catalysis of Co—N.sub.4, inhibiting the shuttle effect of the polysulfides.

APPARATUS AND METHOD FOR ROLL-TO-ROLL MEMBRANE MANUFACTURE
A roll-to-roll process and apparatus is disclosed for treatment of a membrane substrate. The apparatus and process processes the membrane substrate in a forward direction using one or more treatment solutions, and then processes the membrane substrate in a reverse direction using other treatment solutions. The treatment solutions used in the forward and reverse directions are preferably chosen so that the treatment sequence is the same in both directions. In this manner, the membrane substrate can accumulate reaction time by repeated processing in forward and reverse directions. t,?
Method of manufacturing glassine paper
Invention relates to a method of manufacturing glassine paper comprising following steps of producing paper by forming a paper web in a forming section and drying the web in a press section and in a pre-drying section; applying film-forming product on both sides of the web; removing moisture from the film-forming product in an after-drying section; passing the web having film-forming product on its surfaces through an on-line calendering process; and reeling up the glassine paper.
