La\u00a0batterie lithium-ion<\/span><\/a>\u00a0est un accumulateur \u00e9lectrochimique qui utilise le\u00a0lithium<\/span><\/a>\u00a0sous une forme ionique.<\/p>\n

Principe de la batterie \u00e0 lithium-ion<\/h2>\n

Cette batterie lib\u00e8re de l’\u00e9lectricit\u00e9 par \u00e9change\u00a0r\u00e9versible<\/span><\/a>\u00a0des ions lithium entre deux\u00a0\u00e9lectrodes<\/span><\/a>\u00a0: une\u00a0anode<\/span><\/a>\u00a0en\u00a0graphite<\/span><\/a>\u00a0et une\u00a0cathode<\/span><\/a>\u00a0en oxyde m\u00e9tallique. Cet \u00e9change se fait au sein d’un \u00e9lectrolyte\u00a0liquide<\/span><\/a>.<\/p>\n

<\/div>\n

Inconv\u00e9nients de cette batterie<\/h2>\n

Ce dispositif pr\u00e9sente certains risques en cas de fuite, de surchauffe ou de formation d’une structure cristalline de lithium entre les \u00e9lectrodes. Diff\u00e9rents syst\u00e8mes \u00e9lectrom\u00e9caniques \u00e9quipent ce type de batterie pour \u00e9viter ces \u00e9v\u00e9nements.<\/p>\n

Avantages de cette batterie<\/h2>\n

Les avantages de la batterie\u00a0lithium-ion<\/span><\/a>\u00a0sont sa tr\u00e8s forte densit\u00e9 \u00e9nerg\u00e9tique (\u00e9nergie<\/span><\/a>\u00a0par unit\u00e9 de\u00a0volume<\/span><\/a>) et son importante \u00e9nergie massique (\u00e9nergie par unit\u00e9 de\u00a0masse<\/span><\/a>). En outre, ce type de batterie n’est pas affect\u00e9 par l’effet-m\u00e9moire et son autod\u00e9charge est r\u00e9duite.<\/p>\n

Ces caract\u00e9ristiques font de cette batterie l’une des meilleures solutions actuelles pour alimenter en \u00e9lectricit\u00e9 les appareils nomades (appareil photo, t\u00e9l\u00e9phone\u00a0mobile<\/span><\/a>) ou les\u00a0v\u00e9hicules<\/span><\/a>\u00a0(voiture hybride,\u00a0voiture\u00a0\u00e9lectrique<\/span><\/a>).<\/p>\n
