Hydrog\u00e8ne<\/h3>\n

Avec un poids atomique standard d’environ 1,008, l’hydrog\u00e8ne est l’\u00e9l\u00e9ment le plus l\u00e9ger du tableau p\u00e9riodique.\u00a0Sa forme monoatomique (H) est la substance chimique la plus abondante de l’Univers, constituant environ 75 % de toute la masse baryonique.

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.

Le lithium trouve 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, aux 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
