A Li-ion cell typically consists of a carbon-based negative electrode (NE); a porous polymer membrane separator (polypropylene and/or polyethylene); and a lithiated transition metal oxide (LiMxOy, M=Co, Ni, and/or Mn) positive electrode (PE). Electrodes are made by casting slurries of PE or NE-materials, PVDF-binder and carbon-black onto metal current collectors. Mixtures of Li-salts and organi...

A stable and high-performance polyimide (PI) fiber mat was prepared via a facile two-step procedure, electrospinning deposition followed by an imidization process. The PI separator presents higher thermal stability (>300 °C) than the commercial polypropylene (PP) (<160 °C). In Li/Cu half-cell configuration, shows long cycle life performance with coulombic efficiency of 82% at 0.5 mA cm–2 after ...

Abstract Uniform migration of lithium (Li) ions between the separator and anode is critical for achieving good quality Li deposition, which much significance metal battery operation, especially Li–sulfur (Li–S) batteries. Commercial separators such as polypropylene or polyethylene can be prepared by wet dry processes, but they indeed cause plentiful porosities, resulting in uneven ion stripping...

Abstract This paper described the plant scale catalytic process of plastic waste materials in order to obtain an alternative fuel from three wastes Polypropylene (PP), Polystyrene (PS) and Polyethylene (PE). Pyrolysis is thermochemical decomposition plastics at elevated temperatures (in absence or little supply oxygen) into a range useful products: gas, liquid, solid residue. These have consist...

Development of practical lithium (Li) metal batteries (LMBs) remains challenging despite promises Li anodes (LMAs), owing to dendrite formation and highly reactive surface nature. Polyolefin separators used in LMBs may undergo severe mechanical chemical deterioration when contacting with LMAs. To identify the best polyolefin separator for LMBs, this study investigated separator-deterministic cy...
