With increasing demand for high performance energy storage devices, the feasibility of reliable and functional energy storage devices that well operates under extreme conditions is of prime importance for expanding applicative fields as well as for understanding materials’ intrinsic and extrinsic properties and device physics. In this talk, I will introduce the control in the physical structure and chemical composition of 2D nanomaterials for ultracapacitive energy storage devices under limited circumstances, where conditions are classified into thermodynamic (e.g. pressure, volume and temperature) and kinetic (e.g. high rate and frequency) variables. Firstly, I will focus on truly reversible pseudocapacitance of oxidized black phosphorous and their charge storage mechanism. Secondly, I will introduce porous MXene hybrids for large-scale flexible AC filtering energy storage devices with the record high volumetric capacitances.

The CEA-Grenoble site is a regulated access/restricted area. The access to the Blg C5/Room 421A is conditioned to a CEA badge request to be made NO LATER THAN Wednesday, Dec. 11, 2019 at 3:00 pm. Please contact Patrice Rannou  and send an electronic version of your passport/ID. Please do note that a valid ID (National ID card or passport only) will be required to collect your badge at the main entrance (Blg A2) of CEA-Grenoble (17 Avenue des martyrs, 38054 Grenoble Cedex 9). Last but not the least, do take into account that Blg C5 is located at a walking distance of ca. 10 min from the Blg A2 where you will collect your badge. Collecting your badge ca. 15-30 minutes before the start of the invited seminar is recommended.
