Enhanced performance of common electrode materials obtained by means of atmospheric plasma coatings Robotti, Marco Dosta Parras, Sergi Gardon Ramos, Marc Kourasi, M. Mellor, B. Wills, R. García Cano, Irene Guilemany, J. M. (José María) Elèctrodes Revestiments Aliatges Electrodes Coatings Alloys 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. 2020-04-24T07:55:07Z 2020-04-24T07:55:07Z 2016-02-01 2020-04-24T07:55:07Z info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 2352-152X https://hdl.handle.net/2445/157337 656172 eng Versió postprint del document publicat a: https://doi.org/10.1016/j.est.2015.12.001 Journal Of Energy Storage, 2016, vol. 5, p. 127-133 https://doi.org/10.1016/j.est.2015.12.001 cc-by-nc-nd (c) Elsevier, 2016 http://creativecommons.org/licenses/by-nc-nd/3.0/es info:eu-repo/semantics/openAccess 7 p. application/pdf Elsevier Articles publicats en revistes (Ciència dels Materials i Química Física)
