Lithium et Cadmium – \u00c0 propos des \u00e9l\u00e9ments<\/h2>\n<\/div><\/div>\n
\n
\"\"<\/div>
\n

Lithium<\/h3>\n

C’est un m\u00e9tal alcalin doux et blanc argent\u00e9.\u00a0Dans des conditions standard, c’est le m\u00e9tal le plus l\u00e9ger et l’\u00e9l\u00e9ment solide le plus l\u00e9ger.\u00a0Comme tous les m\u00e9taux alcalins, le lithium est hautement r\u00e9actif et inflammable et est stock\u00e9 dans de l’huile min\u00e9rale.

\n

Cadmium<\/h3>\n

Le cadmium est un m\u00e9tal mou, blanc bleu\u00e2tre, chimiquement similaire aux deux autres m\u00e9taux stables du groupe 12, le zinc et le mercure.\u00a0Dans l’industrie nucl\u00e9aire, le cadmium est couramment utilis\u00e9 comme absorbeur de neutrons thermiques en raison de la section efficace d’absorption des neutrons tr\u00e8s \u00e9lev\u00e9e de 113Cd.\u00a0Le 113Cd a une section efficace d’absorption sp\u00e9cifique.

Lithium et Cadmium – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Lithium<\/a><\/h3>\n

Le lithium a de nombreuses applications, de la graisse lubrifiante, aux ajouts d’alliages notamment pour les alliages d’aluminium et de magn\u00e9sium, aux \u00e9maux pour c\u00e9ramiques, et enfin, les batteries au lithium.\u00a0En particulier, le lithium joue et continuera de jouer un r\u00f4le de plus en plus important dans l’avenir de l’air pur aliment\u00e9 par batterie.\u00a0Les batteries au lithium sont largement utilis\u00e9es dans les appareils \u00e9lectroniques grand public portables et dans les v\u00e9hicules \u00e9lectriques allant des v\u00e9hicules de grande taille aux jouets radiocommand\u00e9s.\u00a0Le terme \u00ab\u00a0batterie au lithium\u00a0\u00bb fait r\u00e9f\u00e9rence \u00e0 une famille de diff\u00e9rentes chimies lithium-m\u00e9tal, comprenant de nombreux types de cathodes et d’\u00e9lectrolytes, mais tous avec du lithium m\u00e9tallique comme anode.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

\n
\n
\n

Cadmium<\/a><\/h3>\n

Le cadmium est principalement consomm\u00e9 pour la production de batteries rechargeables au nickel-cadmium.\u00a0En 2009, 86 % du cadmium \u00e9tait utilis\u00e9 dans les piles, principalement dans les piles rechargeables au nickel-cadmium.\u00a0Les autres utilisations finales comprennent les pigments, les rev\u00eatements et le placage, et comme stabilisants pour les plastiques.\u00a0La fabrication de cellules solaires pourrait devenir un autre march\u00e9 important pour le cadmium \u00e0 l’avenir.\u00a0Dans l’industrie nucl\u00e9aire, le cadmium est couramment utilis\u00e9 comme absorbeur de neutrons thermiques en raison de la section efficace d’absorption des neutrons tr\u00e8s \u00e9lev\u00e9e de 113Cd.\u00a0Le 113Cd a une section efficace d’absorption sp\u00e9cifique.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
