摘要： There is provided a method for sealing a filling orifice formed on a wall of a container in a leak-proof manner using a stopper arrangement comprising a tubular member with a flange having an upper face, and a lower face for covering the orifice, and a mandrel with a stem which is housed inside the tubular member, the force necessary for rupturing the stem being greater than the force resulting from the entry and advancement of a head of the mandrel inside the tubular member, comprising introducing the stopper arrangement into the orifice, bringing the nosepiece of the riveting tool into abutment with the upper face of the flange, actuating the riveting tool so as to exert a tensile force on the stem and bring about expansion of the tubular member against the wall of the orifice and rupturing the stem of the stopper arrangement.

摘要： A lithium-ion battery including a negative electrode (anode) containing lithium titanate oxide (Li4Ti5O12) (LTO) as an active material and a stable interface layer disposed on a surface of the electrode; a positive electrode (cathode); an electrolyte containing a solvent and an impedance growth reducing additive; and a separator disposed between the electrodes. The LTO-based cell with the stable interface layer on the negative electrode is formed by holding the potential of the negative electrode below the reduction potential of the impedance growth reducing additive for a sufficient length of time during a first formation cycle. The stable interface layer on the negative electrode mitigates impedance growth on the positive electrode over cycle life. When the impedance growth reducing additive is fluoroethylene carbonate (C3H3FO3), the stable interface layer includes a LiF deposit.
