Abstract: Disclosed is a method of estimating the state-of-charge of a rechargeable battery, taking into account the factors battery spread and ageing. The method comprises the steps of: determining the starting state-of-charge of the battery by measuring the voltage across the battery and converting this measured value into a state-of-charge value; charging the battery; integrating the charge current and determining the accumulated charge during charging of the battery and adding said value to the starting state-of-charge. Also disclosed is a method for determining the use time left of a rechargeable battery.

Abstract: The invention relates to a method of manufacturing a lithium battery, which method includes the following steps: A) forming at least one anode and at least one cathode; B) forming at least one assembly that includes the anode, a separator layer and the cathode by positioning the separator layer between the anode and the cathode, and C) realizing an ultimate configuration for the assembly. The invention also relates to a lithium battery, which includes at least one lamination of at least one lithium cathode, and an anode that is connected to the lithium cathode via intermediate separator means. The invention also relates to an electrical appliance that includes such a lithium battery.

Abstract: A hydrogen storage material has a magnesium-containing intermetallic compound which can form a hydride with hydrogen. The intermetallic compound has an alloy of magnesium and a trivalent metal selected from the group of Sc, Y, La and the rare earth elements. The hydrogen storage material can further have a catalytically active material.
