Abstract: The invention relates to powdered lithium oxide Li2O, which has a specific surface area according to BET of at least 5 m2/g and a bulk density of at most 0.3 g/ml, a process for its preparation and its use in the preparation of overlithiated metal oxides.

Abstract: A connection box for a system of an aircraft is provided, which includes a plurality of connection boxes, with a holder for holding a line connector for the supply of the system of the aircraft, wherein the system includes, in addition to this connection box, a further connection box with a holder for holding a line connector for the supply of the system of the aircraft. The connection box is configured to receive the further connection box in such a way that both connection boxes can be mounted under an opening in the floor of the aircraft so that both connection boxes are accessible from the opposite side of the floor through the opening in the floor.

Abstract: A construction group of an aircraft for feeding a line to a connector section of the cabin module includes a flex zone for providing of at least one cabin module having a connector section for physical connection to a line of the aircraft. The flex zone is configured to receive different cabin modules and/or a cabin module at different positions. The construction group further includes a guide element for guiding the line to be connected to the connector section along the fuselage of the aircraft, and a support element extending along the flex zone for feeding the line from the guide element to the connector section, wherein during the receiving of the construction group in the aircraft, the longitudinal axis of the support element includes a component in direction of the attitudinal axis of the aircraft.
