MXenes, 2D materials, are increasingly being studied for energy applications because of their structural stability. Using a multi-technique approach, it was possible to identify how structure can affect the electrochemical stability of the material in sodium ion batteries.<\/p>\n","protected":false},"author":93,"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"tags":[1301],"targets":[1317],"pubblicazioni_tipologie":[773],"class_list":["post-196439","pubblicazioni","type-pubblicazioni","status-publish","hentry","tag-sodium-ion-batteries","targets-research","pubblicazioni_tipologie-isi-article-en"],"acf":{"projects":{"ID":191041,"post_author":"464","post_date":"2024-07-10 15:54:35","post_date_gmt":"2024-07-10 13:54:35","post_content":"","post_title":"Storage systems, including electrochemical and power-to-gas, and their interfaces with grids","post_excerpt":"The more ambitious the decarbonisation goals become, the more important energy storage is.

The most common MXene composition Ti3C2Tx (T = F,
\nO) shows outstanding stability as anode for sodium ion batteries (100% of capacity retention after 530 cycles with charge efficiency >99.7%). However, the reversibility of the intercalation\/deintercalation process is strongly affected by the synthesis parameters determining, in turn, significant differences in the material structure. This study proposes a new approach to identify the crystal features influencing the performances, using a structural model built with a multitechnique approach that allows exploring the short-range order of the lamella. The model is then used to determine the long-range order by inserting defective elements into the structure. With this strategy it is possible to fit the MXene diffraction patterns, obtain the structural parameters including the stoichiometric composition of the terminations (neutron data), and quantify the structural disorder which can be used to discriminate the phases with the best electrochemical properties.<\/p>\n","scarica_file":false,"link_estreno":[{"link_text":"Download ISI Article","link":"https:\/\/pubs.acs.org\/doi\/10.1021\/acs.nanolett.1c02809#"}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2021-09-23","autori":"C.
