Samsung est r\u00e9guli\u00e8rement critiqu\u00e9 pour la capacit\u00e9 de ses batteries bien en-de\u00e7\u00e0 des performances offertes par les fabricants de smartphones chinois. Qu\u2019\u00e0 cela ne tienne, la firme sud-cor\u00e9enne d\u00e9velopperait une batterie \u00e0 double cellule impressionnante.<\/strong><\/p>\n

\"Samsung<\/p>\n

L\u2019un des principaux crit\u00e8res sur lesquels les utilisateurs sont regardant lorsqu\u2019ils ach\u00e8tent un nouveau smartphone est sans conteste la\u00a0capacit\u00e9 de la batterie<\/strong>. Et s\u2019il existe un fabricant r\u00e9guli\u00e8rement point\u00e9 du doigt sur cet aspect, c\u2019est bien\u00a0Samsung<\/strong>, d\u2019autant plus que la puissance de charge de ses smartphones Galaxy stagne, elle aussi \u2013 \u00e0 ce propos,\u00a0la firme sud-cor\u00e9enne devrait enfin am\u00e9liorer la recharge filaire, mais \u00e9galement sans fil, avec sa future gamme de Galaxy S26<\/a>.<\/p>\n

<\/div>\n<\/div>\n<\/div>\n

Mais ce n\u2019est pas la seule mise \u00e0 niveau majeure sur laquelle la marque travaillerait. La division Samsung Display Interface (SDI)\u00a0testerait une impressionnante batterie de 20 000 mAh<\/strong>\u00a0\u2013 un v\u00e9ritable bond vis-\u00e0-vis des capacit\u00e9s actuelles des batteries qui \u00e9quipent les smartphones haut de gamme de la marque (environ 5 000 mAh).<\/p>\n

Samsung testerait une impressionnante batterie en silicium-carbone<\/h2>\n

Pour atteindre une telle capacit\u00e9, Samsung semble\u00a0s\u2019inspirer des\u00a0fabricants chinois<\/a><\/strong>\u00a0: cette\u00a0batterie serait en silicium-carbone (Si\/C)<\/strong>, une technologie capable d\u2019accro\u00eetre la densit\u00e9 \u00e9nerg\u00e9tique d\u2019une batterie (en stockant jusqu\u2019\u00e0 10 fois plus d\u2019ions lithium), sans augmenter l\u2019encombrement physique de l\u2019appareil.<\/p>\n

Cela gr\u00e2ce au mat\u00e9riau utilis\u00e9 pour l\u2019anode (la zone de stockage des ions lithium). Comme le rappellent nos confr\u00e8res de\u00a0Wccftech<\/a>, l\u2019anode des batteries lithium-ions est g\u00e9n\u00e9ralement faite en graphite, l\u00e0 o\u00f9 celle des batteries Si\/C est constitu\u00e9e d\u2019un mat\u00e9riau composite silicium-carbone nanostructur\u00e9.<\/p>\n

@phonefuturist et @SPYGO19726 ont partag\u00e9 sur X (ex-Twitter) les\u00a0capacit\u00e9s de cette batterie Si\/C \u00e0 double cellule exp\u00e9rimentale<\/strong>. La premi\u00e8re cellule aurait une \u00e9paisseur de 6,3 mm et une capacit\u00e9 de 12 000 mAh, la seconde afficherait une capacit\u00e9 de 8 000 mAh et une \u00e9paisseur de 4 mm. La batterie pourrait supporter 960 cycles de charge sur un an et 27 heures de temps d\u2019\u00e9cran allum\u00e9 avant de se vider compl\u00e8tement.<\/p>\n

Si une telle capacit\u00e9 fait r\u00eaver, ne vous attendez pas \u00e0 la retrouver dans les prochains\u00a0Galaxy S26, qui devraient embarquer une batterie de 4 300 mAh<\/a>\u00a0\u2013 au lieu des 4 900 initialement vis\u00e9s. Cette batterie exp\u00e9rimentale est loin d\u2019\u00eatre aboutie : elle pr\u00e9sente des d\u00e9fauts qui devront absolument \u00eatre corrig\u00e9s avant qu\u2019elle n\u2019arrive sur le march\u00e9. Si ses performances \u00e0 court terme sont tr\u00e8s bonnes, sa stabilit\u00e9 \u00e0 long terme ne l’est pas : les tests font \u00e9tat d\u2019un gonflement de pr\u00e8s de 80 % de la cellule de 8 000 mAh.<\/p>\n
