A poly(vinylidene co-hexafluoropropylene) (PVDF-HFP) membrane is functionalized with polyaniline (PANI) and graphene oxide (GO) nanoparticles. The obtained PVDF-HFP polymer electrolyte membranes (PEMs) have been characterized implemented in lithium-ion batteries. As a result, the PVDF-HFP/PANI shows highest ionic conductivity (IC) of 1.04 × 10-3 mS cm-1 compared to pristine PVDF-HFP/PANI/GO ternary membrane; however, PANI addition decreases tensile strength from 4.2 MPa 2.8 MPa. Therefore,...
Solid oxide fuel cells (SOFCs) are efficient yet environmentally benign devices that can convert chemical energy into electrical and heat for large scale of applications. However, higher operating temperature this device limits the selection proper materials to be used as electrode electrolyte well sacrifices durability. Thus, it is desirable develop with superior electrochemical performance at intermediate (600-900 oC) SOFC. LaSrCoFeO3 (LSCF) doped CuO an attracting promising cathode...
A mixture of lanthanum strontium cobalt ferrite (LSCF) and nickel oxide (NiO) makes for a desirable cathode material an IT-SOFC due to its excellent oxygen reduction capability. This study investigates the effect NiO addition into LSCF on physical electrochemical properties.
