  • Publication number: 20200395836
    Abstract: In a linear motor and the linear compressor having the same according to the present disclosure, a plurality of magnets are coupled to a stator equipped with a winding coil, and a mover core made of magnetic material instead of a permanent magnet is provided on the mover, and by the magnetizing plurality of magnets in the same direction, the motor output can increase by increasing thrust instead of decreasing the centering force for the mover core. In addition, as it is applied to a two-pore motor, it is possible to easily control the mover core and to easily perform an assembly operation and a magnetization operation for the magnet. In addition, as the stator is made of a grain-oriented core, core loss may be reduced and the motor efficiency may be improved.

  • Patent number: 8383265
    Abstract: Provided is a lithium secondary battery comprising a lithium transition metal compound-containing cathode and a graphitized carbon-containing anode with addition of a surfactant to the cathode and/or the anode, whereby the addition of the surfactant improves the wettability of an electrolyte on the electrode, thereby increasing the battery capacity and improving rate properties and cycle properties of the battery, in conjunction with a significant reduction of a manufacturing process time of the battery.

  • Publication number: 20070264535
    Abstract: Disclosed herein is a battery pack constructed such that a battery case, in which an electrode assembly is mounted, is made of a laminate sheet having high strength, side sealing parts of the battery case are formed in a specific shape, and a protection circuit module (PCM) is located in the inner space of at least one of the side sealing parts. The side sealing parts in themselves are used as a structure to decide the external shape of the battery pack, and, at the same time, are used as spaces for mounting the PCM therein. Consequently, it is possible to construct the battery pack without using additional pack sheathing members, to simplify the assembly process of the battery pack, and to manufacture the battery pack in a thinner and more compact structure with the reduced manufacturing costs. Furthermore, the PCM is located at either side of the battery cell while the PCM is spaced apart from electrode terminals.

  • Publication number: 20060093908
    Abstract: Provided is a secondary battery having an electrode assembly installed in a battery case made up of a laminated sheet composed of an outer coating layer of a polymer film, a barrier layer of a metal foil and an inner sealant layer of a polyolefin material, wherein the metal foil of the barrier layer is formed of an aluminum alloy, the outer coating layer is formed of polyethylene naphthalate (PEN) and/or the outer surface of the outer coating layer is provided with a polyethylene naphthalate (PET) layer, and wherein the battery has a nail penetration resistance force of more than 6.5 kgf. The battery in accordance with the present invention exhibits further improved safety due to the ability to significantly reduce the probability of invasion, ignition or explosion as compared to conventional batteries, even when the battery is exposed to external physical impact or is pressed by sharp objects.
