Structural and textural analysis of the precursor of Laponite synthesis: Enhanced hydrogen adsorption in a clay material

Mohammad Abdelsater, Martine Lanson, Valérie Magnin, Erwan Paineau, Cristina Coelho, Delphine Vantelon, Erik Elkaim, Jean-Pascal Rueff, Victor Balédent, Marie-Vanessa Coulet, Virginie Marry, Lorella Masci, Laurent Truche, Stéphane Rols, Pascale Launois

This study focuses on a precursor of the synthesis of Laponite, named pre-Laponite. Pre-Laponite shares similar molecular formula and structure with Laponite, but it exhibits reduced long-range order. N2 adsorption isotherms reveal that both materials possess comparable BET (N2) specific surface…

HAXPES at 4th synchrotron generation

Jean-Pascal Rueff

The advent of 4th generation synchrotrons will profoundly renew the HAXPES field of research in the near future. Based on more than 10 years of experience of HAXPES for advanced materials studies at the GALAXIES beamline [1] of the SOLEIL Synchrotron, including investigation of quantum materials [2…

Understanding Degradation Mechanisms in Water‐In‐Salt Electrolyte. Part 2: Impact of the Electrochemical Parameters on the Cycling Behavior of LiFePO₄ versus TiS₂

Célia Doublet, Théo Faverge, Vincent Martin, Hiram Castillo Michel, Jean‐pascal Rueff, Marian Chatenet, Lauréline Lecarme, Claire Villevieille

Water‐in‐salt electrolytes (WISE) have emerged as a promising route for the development of safe and high‐voltage aqueous lithium‐ion batteries, owing to their expanded electrochemical stability window (ESW) and reduced safety issue. Despite this potential, the long‐term cycling performance of WISE‐…
