However, its synthesis involves toxic reagents and generates impurities, requiring significant solvent use for purification. This study introduces a novel synthetic method using sodium hydroxide as the sole reagent, which acts as both a base and Na source in the ion exchange step. With this procedure, we reduce the amounts of chemicals, diminish toxicity, improve the purity of the target compound, and use less solvent while maintaining comparable electrochemical performance. Additionally, the procedure is carried out under anhydrous conditions that avoid the undesirable hydrolysis of the imine linkages. In a previous report, the processing of the composite electrode was not established. In this article, we address this issue; the electrochemical performance, specifically the rate capability, is enhanced by processing the electrodes in laminate form rather than powder. As alternative to N-methyl-2-pyrrolidone (NMP), a common but disadvantageous solvent in laminate processing, other solvents were explored by testing acetone (DMK), methylisopropylketone (MIPK), and a DMK-NMP mixture. The remarkable electrochemical performance (specific capacity of 260\u2013280 mAh\/g, and capacity retentions higher than 84% at 1C (260 mA\/g) remained consistent across these solvents. Furthermore, we investigated replacing copper with aluminum as the current collector to reduce costs and increase the energy density of the battery. While aluminum performed comparably to copper at low specific currents C\/10 (26 mA\/g), it showed a significant shift in the redox process potentials at higher specific currents.<\/jats:p>","DOI":"10.3390\/ma17194918","type":"journal-article","created":{"date-parts":[[2024,10,9]],"date-time":"2024-10-09T07:39:52Z","timestamp":1728459592000},"page":"4918","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Towards More Sustainable Schiff Base Carboxylate Anodes for Sodium-Ion Batteries"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-5459-0439","authenticated-orcid":false,"given":"Irene","family":"G\u00f3mez-Berenguer","sequence":"first","affiliation":[{"name":"Departamento de Qu\u00edmica Inorg\u00e1nica, Universidad Complutense de Madrid, 28040 Madrid, Spain"},{"name":"Instituto de Qu\u00edmica Org\u00e1nica General, Consejo Superior de Investigaciones Cient\u00edficas, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1179-884X","authenticated-orcid":false,"given":"Bernardo","family":"Herrad\u00f3n","sequence":"additional","affiliation":[{"name":"Instituto de Qu\u00edmica Org\u00e1nica General, Consejo Superior de Investigaciones Cient\u00edficas, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5974-6147","authenticated-orcid":false,"given":"Jos\u00e9 Manuel","family":"Amarilla","sequence":"additional","affiliation":[{"name":"Instituto de Ciencia de Materiales de Madrid, Consejo Superior de Investigaciones Cient\u00edficas, 28049 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8577-9572","authenticated-orcid":false,"given":"Elizabeth","family":"Castillo-Mart\u00ednez","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica Inorg\u00e1nica, Universidad Complutense de Madrid, 28040 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11636","DOI":"10.1021\/cr500192f","article-title":"Research Development on Sodium-Ion Batteries","volume":"114","author":"Yabuuchi","year":"2014","journal-title":"Chem.
