Air Dehydration Membranes for Nonaqueous Lithium–Air Batteries
May 28 , 2021
Jian Zhang, Wu Xu,* Xiaohong Li, and Wei Liuz PTFE thin film coated on the porous metal substrate sheet.— In the third stage of our membrane development, the PTFE membranes were coated onto the metal substrates by spin coating with DuPont PTFE TE-3859 fluoropolymer resin. The resin is anegatively charged, hydrophobic colloid containing approximately60% by total weight of 0.05–0.5 m PTFE particles ...

An Approach to Make Macroporous Metal Sheets as Current Collectors for Lithium-Ion Batteries
Jun 23 , 2021
The freestanding, laminated film was sintered in air by increasing the temperature of the furnace at a slow rate to 1000°C, holding at1000°C for 1 h, and then decreasing the temperature at a rate of5°C/min to room temperature. This high temperature treatment was done to completely burn all carbon and organic materials to generate a porous structure and to simultaneously allow CuO particles to conn...
