Alexia Lemoine,Ronan Invernizzi,Germain Vallverdu,L. Madec,Jacob Olchowka,Liliane Guerlou-Demourgues,Isabelle Baraille,Delphine Flahaut +7 more
TL;DR: In this paper, the surface reactivity of layered β(III)-cobalt oxyhydroxide, β(3)-CoOOH was investigated by implementing a multiscale study associating both experimental, surface characterization by X-ray photoemission spectroscopy (XPS) and scanning electron microscopy and first-principles calculations.

Stabilization and Improvement of Energy Storage Performance of High Mass Loading Cobalt Hydroxide Electrode by Surface Functionalization
Jacob Olchowka,Ronan Invernizzi,Alexia Lemoine,Joachim Allouche,Isabelle Baraille,Delphine Flahaut,Liliane Guerlou-Demourgues +6 more
TL;DR: In this article, a sonochemical approach was proposed to functionalize the surface of Co(OH)2 nanomaterials by EmimBF4 ionic liquid that greatly improves the stability and the electrochemical performances of high mass loading electrodes (13 mg cm−2).

Relating the Electrochemical Behavior of Birnessite to the Morphology and Specific Surface: Interest of Studying the Surface Reactivity
Alexia Lemoine,Ronan Invernizzi,Germain Salvato Vallverdu,Jacob Olchowka,Liliane Guerlou-Demourgues,Isabelle Baraille,Delphine Flahaut +6 more
TL;DR: In this paper , a multiscale study was carried out on three birnessites, nonprotonated (Na-MnO2, K-mnsO2 and HT-mno2), and protonated(HNa-mmo2, HK-mgo2 and HHT-momo2), to determine the surface reactivity of each material and show the impact of the surface properties on the energy storage of the supercapacitors.

Composite Mn–Co electrode materials for supercapacitors: why the precursor's morphology matters!
Ronan Invernizzi,Alexia Lemoine,L. Madec,François Weill,Marie-Anne Dourges,Céline Tang,Domitille Giaume,Isabelle Baraille,Pierre-Louis Taberna,Delphine Flahaut,Jacob Olchowka,Liliane Guerlou-Demourgues +11 more
TL;DR: In this article , three layered MnO2 phases with various morphologies (veils, nanoplatelets and microplatelets) were combined with electronic conductor cobalt oxyhydroxides with different platelet sizes (∼20 nm vs. 70 nm wide), to synthesize 6 different composites by exfoliation and restacking processes.
