Lithium-ion and sodium-ion batteries are an assembly of different components (current collectors, electrodes, electrolyte, separator)<\/strong>, themselves made of different materials<\/strong>. An electrode, for example, consists of an electroactive material<\/strong>, an electronically conductive<\/strong> additive<\/strong> and a polymer binder<\/strong>. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The evaluation of a component or material consists of characterizing its battery performance<\/strong>, such as cyclability<\/strong> or charging speeds<\/strong>, possibly in comparison with a reference (a standard or the state of the art in the literature), up to a preliminary analysis of the causes of<\/strong> performance degradation<\/strong> (first verdict).<\/p>

The PLASSMAT platform is equipped to manufacture electrodes, assemble<\/strong> button cell<\/strong> and pocket cell<\/strong> batteries<\/strong>, and measure their electrochemical performance<\/strong>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
