HOCHSPANNUNGS-POSITIV-ELEKTRODENMATERIAL MIT SPINELLSTRUKTUR AUF DER BASIS VON NICKEL UND MANGAN FÜR LITHIUMZELLENBATTERIEN |
摘要 |
A spinel structure compound of the formula LiNi0.4Mn1.6O4-δ, wherein δ>0, has a lattice parameter of from 8.179 to 8.183 Å. The compound may be prepared by mixing carbonated precursors under stoichiometric conditions to produce a mixture, subjecting the mixture to a first heat treatment at a temperature of from 500 to 700° C., and then subjecting the mixture to one or more annealing treatments at a temperature of from 700 to 950° C., followed by cooling in a medium containing oxygen. The spinel structure compound may be used as an electrochemically active material in an electrode, for example an electrode of a battery. |
