Ceramic-in-polymer versus polymer-in-ceramic polymeric electrolytes—A novel approach

Thin, flexible and thermally stable ceramic membranes as separator for lithium-ion batteries

“…The interfacial resistance of Li/PCM/Li cell increases with time during its initial days of storage, then suddenly decreases and remains stable after a period ten days (250 ohms). Thus the prepared PCM is found to be stable towards lithium metal electrode, which is better than our earlier results [28] and almost comparable with the results achieved by Wieczorek and coworkers with membranes of larger pores and percentage of porosity [10]. The better stability of PCM with lithium metal anode is ascribed to the MgAl 2 O 4 , ceramic's scavenging ability to trace the solvent impurities [32].…”

“…Costa et al, have also reviewed battery separators based on vinylidene fluoride(VDF) polymers and copolymers for lithium-ion battery applications [9]. Syzdek et al introduced a novel polymer-in-ceramic membrane in which the polymer is introduced in a ceramic matrix, and the materials are found to have long-term stability in contact with a lithium metal anode [10]. In order to increase the thermal stability of the membranes, Jeong and co-workers coated Al 2 O 3 on both sides of a porous poly ethylene membrane [11].…”

Nanocomposite polymer membrane derived from nano TiO2-PMMA and glass fiber nonwoven: high thermal endurance and cycle stability in lithium ion battery applications

“…It's well known that the poor interfacial compatibility of electrodes and polymer electrolytes or polyolefin separator filled with liquid electrolytes will cause the bad cycle 40 performance of Li-ion batteries, 36,37 and the existence of ceramic particles in polymer electrolyte membrane or coating on polyolefin separator is an effective way to improve the cycle performance. 38 In this work, the R inf of the cell with NCPE is much smaller 50 than that of the cell with PP separator. This confirms that improving interfacial compatibility of electrodes and polymer electrolytes or polyolefin separator filled with liquid electrolyte will result in good cycle performance of cells.…”

Electrolytes for high-energy lithium batteries

“…Recently, Syzdek et al (2009) reported on a liquid-inceramic composite, where the ceramic provides a continuous supporting phase and is soaked with a liquid electrolyte. The porous ceramic matrix was formed by a tape-casting method, uni-axial pressing and grain sintering of a slurry of c-Al 2 O 3 particles.…”
