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.

摘要： A film made of a fluorinated polymer of the polyvinylidene fluoride type having suitable properties for use as a lithium storage battery separator is produced using a phase inversion technique in which a solution containing the fluorinated polymer is brought into the presence of an atmosphere laden with water vapor to precipitate the fluorinated polymer. The fluorinated polymer can be precipitated by placing the support on which the solution is deposited, in which the fluorinated polymer has been previously dissolved, in an enclosure containing an atmosphere laden with water vapor and thermostatically regulated to a temperature comprised between 30° C. and 70° C. The relative humidity content during precipitation of the fluorinated polymer is advantageously between about 60% and about 98%.
