Title (EN) AN ANODE MATERIAL FOR ULTRAFAST-CHARGING LITHIUM ION BATTERIES AND A METHOD OF ITS SYNTHESIS
(FR) MATÉRIAU D'ANODE POUR CHARGE ULTRA-RAPIDE DE BATTERIES AU LITHIUM-ION ET SON PROCÉDÉ DE SYNTHÈSE
Abstract: front page image
(EN)An anode material for ultrafast-charging lithium ion batteries, the anode material comprising C-Li4Ti5O12. A method of synthesizing an anode material for ultrafast-charging lithium ion batteries, the method comprising the steps of: adding lithium to an organic alcohol to form a first solution; adding titanium via an organic titanium source to the first solution to form a second solution; adding water to the second solution to form a diluted second solution; heating the diluted second solution at a temperature ranging from about 80°C to about 180°C to obtain solid Li4Ti5O12; and annealing the solid Li4Ti5O12 in the absence of air to obtain the anode material comprising C-Li4Ti5O12.
(FR)L'invention concerne un matériau d'anode pour charge ultra-rapide de batteries au lithium-ion, comprenant C-Li4Ti5O12. L'invention concerne également un procédé de synthèse de matériau d'anode pour charge ultra-rapide de batteries au lithium-ion, comprenant les étapes consistant à ajouter du lithium à un alcool organique afin de former une première solution; à ajouter du titane via une source de titane organique à la première solution afin de former une seconde solution; à ajouter de l'eau à la seconde solution afin de former une seconde solution diluée; à chauffer la seconde solution diluée à une température comprise entre environ 80°C et 180°C afin d'obtenir Li4Ti5O12 solide; et à soumettre le Li4Ti5O12 solide à un recuit en l'absence d'air afin d'obtenir le matériau d'anode comprenant C-Li4Ti5O12.
