Also provided herein is a lithium-ion battery including the separator disclosed herein. The separator disclosed herein is excellent in terms of safety, ion permeability, and cycle characteristics.

The present invention provides a non-aqueous electrolytic solution comprising a phosphinoamine-based compound represented by formula (1) below and a lithium ion secondary battery comprising the non-aqueous electrolytic solution. By adding the phosphinoamine-based compound to the non-aqueous electrolytic solution, oxidative degradation in the non-aqueous electrolytic solution is suppressed, and thus gas generation is suppressed. ##STR00001##

The present invention discloses an unmanned aerial vehicle and a battery thereof. The battery includes a battery body and a shell disposed on one end of the battery body. The shell has a clamp button disposed on the side opposite the unmanned aerial vehicle. One end of the clamp button is fixed on the shell and the other is used for detachably connecting with the unmanned aerial vehicle. The clamp button makes the battery detachably connect with the main body of the unmanned aerial vehicle be possible and it is very convenient for changing the battery.

A separator for a rechargeable battery includes a porous substrate and a heat-resistance layer on at least one surface of the porous substrate. The heat-resistance layer includes a binder having a cross-linked structure, a sphere-shaped filler, and a plate-shaped filler, and the plate-shaped filler is included in a smaller amount than the sphere-shaped filler in the heat-resistance layer. A rechargeable battery includes the separator.

Methods and supercapacitor-emulating fast-charging batteries are provided. Methods comprise configuring a fast-charging battery to emulate a supercapacitor with given specifications by operating the fast-charging battery only within a partial operation range which is defined according to the given specifications of the supercapacitor and is smaller than 20%, possibly 5% or 1%, of a full operation range of the fast-charging battery. Devices are provided, which comprise control circuitry and a modified fast-charging lithium ion battery having Si, Ge and/or Sn-based anode active material and designed to operate at 5 C at least and within a range of 5% at most around a working point of between 60-80% lithiation of the Si, Ge and/or Sn-based anode active material, wherein the control circuitry is configured to maintain a state of charge (SOC) of the battery within the operation range around the working point.

A hub comprises a main body with a speaker; a communication module included in the main body; a window formed of a transparent material; a display panel for displaying a screen based on information exchanged via the communication module; and a cover housing coupled to a top of the main body and having a display panel and an opening at an upper surface thereof. The window is provided on an upper surface of the display panel, wherein a normal vector with respect to a predetermined plane in which the opening falls is at an acute angle relative to a horizontal plane, and a vector acquired by orthogonally projecting the normal vector with respect to the horizontal plane faces forward. A portion of the inner surface of the cover housing is parallel with the normal vector, and the window is provided so that an upper surface faces the direction of the normal vector.
