Optimización de espinelas LiCo_yMn_2-yO₄ para electrodos positivos de baterías recargables de ion-litio mediante ajuste del dopado y de la temperatura de síntesis

Boletín de la Sociedad Española de Cerámica y Vidrio, 2004
The synthesis of LiCoyMn2‑yO4 (0 < y ≤ 0.33) spinels with optimised electrochemical performances in the 4V region has been carried out. They have been obtained by an original procedure designed by us, based on the reaction at 750ºC between the ...
