Title (EN) PROCESS FOR THE PREPARATION OF HIGH VOLTAGE NANO COMPOSITE CATHODE (4.9V) FOR LITHIUM ION BATTERIES
(FR) PROCÉDÉ POUR LA PRÉPARATION D'UNE CATHODE À BASE DE NANOCOMPOSITE POUR HAUTE TENSION (4,9 V), POUR DES ACCUMULATEURS AU LITHIUM-ION
Abstract: front page image
(EN)An olivine structured nano-composite LiMxMn1-xPO4/C was synthesized by a sol-gel assisted high energy ball mill method and the synthesis method does not require any inert atmosphere. Electrochemical cycling studies were carried out between 3.0-4.6V using 1M LiPF6 in 1:1 EC/DEC as electrolyte. The charge/discharge cycling studies of the nano-composite exhibit an average discharge capacity of 158 mAh/g at 0.1 C rate over the investigated 50 cycles.
(FR)Un nanocomposite à structure d'olivine LiMxMb1-xPO4/C a été synthétisé par un procédé de broyage à billes à haute énergie assisté par sol-gel. Le procédé de synthèse ne nécessite pas d'atmosphère inerte. Des études de cycles électrochimiques ont été réalisés entre 3,0 et 4,6 V en utilisant comme électrolyte 1M LiPF6 dans un rapport 1:1 EC/DEC. Les études des cycles de chargement et de déchargement du nanocomposite indiquent une capacité moyenne de déchargement de 158 mAh/g sous 0,1 C sur les 50 cycles étudiés.
