Secondary battery electrode, and method for producing same
摘要
說明書
The lithium secondary battery according to an exemplary embodiment of the present invention may be produced by producing an electrode assembly including a separator interposed between a positive electrode and a negative electrode, charging the produced electrode assembly in a case, and injecting the electrolyte and sealing the case. Otherwise, the lithium secondary battery may be produced by charging the electrode assembly impregnated with an electrolyte in a case and sealing the case. A battery case may be any case which is commonly used in the lithium secondary battery field. As an example, the case may have a cylindrical shape, a square shape, a pouch shape, or a coin shape, but the present invention is not limited to the specific shapes of the battery case, of course.
The present invention includes a battery module, in which the secondary battery described above, as an example, a lithium secondary battery is used as a unit cell and the unit cells are connected in series or in parallel.
The present invention includes a device to which electric power is supplied by the secondary battery described above, as an example, the lithium secondary battery. As a specific example, the device may be an electric automobile, a hybrid electric automobile, a plug-in hybrid electric automobile, a system for power storage, and the like, but is not limited thereto.
