A polybenzimidazole/graphite oxide based three layer membrane for intermediate temperature polymer electrolyte membrane fuel cells [PDF]

open access: yes, 2016
A three layer membrane (TLM) of polybenzimidazole/graphite oxide/polybenzimidazole (PBI/GO/PBI) has been fabricated as an electrolyte for intermediate temperature polymer exchange membrane fuel cells (IT-PEMFCs). The membrane is prepared by encapsulating

High‐Performance, Flame‐Retardant, Binder‐Free Li‐Hectorite‐Polybenzimidazole Fiber Separator for Li‐Ion Batteries

open access: yesMacromolecular Materials and Engineering
Li‐Hectorite (Li‐Hec) clays have inherent 2D diffusion slits offering high lithium (Li+) ion conductivity. Such Li‐Hec clays spontaneously delaminate into flexible nanosheets, allowing them to be coated on high‐temperature stable polybenzimidazole (PBI ...
