Polymer electrolyte membrane water electrolyzers (PEMWEs) are electrochemical devices that can be used for the production of hydrogen. In a PEMWE anode is most complex electrode to study due high overpotential oxygen evolution reaction (OER), not widely understood. A physical bottom-up multi-scale transient model describing operation proposed here. This includes detailed description elementary OER kinetics in anode, non-equilibrium behavior nanoscale catalyst-electrolyte interface, and...
Proton exchange membranes (PEM's) are currently under investigation for membrane water electrolysis (PEMWE) to deliver efficient production of the high purity hydrogen needed supply emerging clean-energy technologies such as fuel cells. The microblock aromatic ionomer described in this work achieves mechanical strength an aqueous environment a result its designed, biphasic morphology and displays many qualities required PEM. new thus shows good proton conductivity (63 mS cm–1 at 80 °C 100%...
A correlation between the evolution of KF content in SEI and cycling performance non-aqueous potassium-ion hybrid supercapacitor (KIC).
Ru and Ir based materials were prepared by the thermal decomposition of polymeric precursor's method. The anode catalysts free from carbon substrate obtained tailoring reaction process to avoid occurrence CO 2 formation during water electrolysis. Various contents added in catalytic compositions for improving oxidation-resistance RuO which was best metallic oxide H2O splitting. Their physical characterizations revealed presence agglomerates due probably heat treatment consisting removal...
Hybrid supercapacitors have been developed in the pursuit of increasing energy density conventional without affecting power or lifespan. Potassium-ion hybrid (KIC) consist an activated carbon capacitor-type positive electrode and a graphitic battery-type negative one working electrolyte based on potassium salt. Overcoming inherent problems (irreversible capacity, extensive volume expansion, dendrites formation), non-reproducibility results was major obstacle to development this KIC...
Aiming at increased performances for battery systems, lithium/sulfur technology (Li/S) is widely regarded as one of the most promising alternatives to lithium-ion systems. Although cyclability best Li/S current prototypes needs be further improved, potentially superior expected energy density (400-600 Wh.Kg -1 ) explains high attention that this has received over last 10 years. 1 Different studies 2,3 have pointed out both sulfur loading and utilization are required achieve capacity targeted...
The numerous battery gigafactory projects show that the Li-ion sector is booming. Although groundbreaking technologies such as all-solid-state batteries mobilize a lot of research effort, current liquid technology still needs to be updated. Only few publications are related electrode manufacturing. However, increasing active material content, areal capacity, or solid slurry content key improve energy density but also manufacturing costs. objectives this thesis work understand and preparation...
