urn:hdl:2445/157819 Enhancing the performance of common electrode materials by means of atmospheric plasma spray coatings Robotti, Marco Dosta Parras, Sergi Gardon Ramos, Marc García Cano, Irene Guilemany, J. M. (José María) Kourasi, M. Mellor, B. Wills, R. Elèctrodes Revestiments Titani Electrodes Coatings Titanium Atmospheric plasma spraying is used here to obtain titanium sub-oxide coatings on the following electrode substrates: a 316 stainless steel sheet, an aluminium alloy 2024 sheet, a carbon-polymer composite and nickel foam. It is necessary to increase the roughness of the substrate to aid the adhesion of the coating to the smooth electrodes; this is especially critical for the fragile carbon-polymer composite. High-energy conditions increase the strain caused by the mismatch between coefficients of thermal expansion when coating the thin steel and aluminium sheets, and degraded the carbon-polymer composite and nickel foam. Therefore, it is necessary to adjust the spraying parameters to lower-energy conditions in order to achieve well-bonded and homogeneous coatings on all four substrates and avoid the presence of cracks in their cross-section area. The suitability of the coated materials as battery electrodes was studied. 2020-04-28T08:48:56Z 2020-04-28T08:48:56Z 2015-12-06 2020-04-28T08:48:57Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Versió postprint del document publicat a: https://doi.org/10.2016/j.est.2015.12.001 Journal Of Energy Storage, 2015, vol. 5, p. 127-133 https://doi.org/10.2016/j.est.2015.12.001 cc-by-nc-nd (c) Elsevier, 2015 http://creativecommons.org/licenses/by-nc-nd/3.0/es info:eu-repo/semantics/openAccess Elsevier Articles publicats en revistes (Ciència dels Materials i Química Física)
