Definitions
- the present invention relates to a cable type secondary battery free of deformation.
- a secondary battery is a device that converts external electrical energy into chemical energy, stores it, and generates electricity when needed.
- the term “rechargeable battery” is also used to mean that it can be charged multiple times.
- Commonly used secondary batteries include lead storage batteries, nickel cadmium batteries (NiCd), nickel hydrogen storage batteries (NiMH), lithium ion batteries (Li-ion), and lithium ion polymer batteries (Li-ion polymer). Secondary batteries offer both economic and environmental advantages over primary batteries that are used once and discarded.
- Secondary batteries are currently used where low power is used. Examples are devices, handhelds, tools, and uninterruptible power supplies that help start up the car. Recently, the development of wireless communication technology has led to the popularization of portable devices, and there is also a tendency to wirelessize many kinds of conventional devices, and the demand for secondary batteries is exploding. In addition, hybrid vehicles and electric vehicles have been put to practical use in terms of prevention of environmental pollution, and these next-generation vehicles employ technologies that use secondary batteries to reduce value, weight, and increase lifespan.
- secondary batteries are cylindrical, rectangular or pouch type batteries. This is because the secondary battery is manufactured by mounting an electrode assembly composed of a negative electrode, a positive electrode, and a separator inside a pouch-shaped case of a cylindrical or rectangular metal can or an aluminum laminate sheet, and injecting an electrolyte into the electrode assembly. Therefore, since a certain space for mounting the secondary battery is essentially required, the cylindrical, square or pouch type of the secondary battery has a problem in that it acts as a limitation for the development of various types of portable devices. Accordingly, there is a need for a new type of secondary battery that is easily deformed.
- Korean Patent No. 0444711 discloses a linear battery composed of a plurality of negative electrodes and a positive electrode having a separator interposed between a negative electrode and a positive electrode. It is disclosed, but the flexibility is not good. In addition, when excessive deformation occurs in the cable type secondary battery due to external force, there is a problem that detachment of the active material may occur.
- an object of the present invention is to provide a secondary battery having a novel linear structure that is easily deformed and can maintain stability and excellent performance of the secondary battery.
- a cable type secondary battery includes a negative electrode current collector having a horizontal cross section of a predetermined shape and extending in a longitudinal direction; A negative electrode active material pattern layer formed on the outer surface of the negative electrode current collector to be spaced apart from each other at predetermined intervals; An electrolyte layer surrounding the anode active material pattern layer and serving as a passage of charged ions; A cathode active material pattern layer formed on an outer surface of the electrolyte layer, the cathode active material patterns being spaced apart from each other at predetermined intervals at positions corresponding to the anode active material patterns; And a positive electrode current collector surrounding an outer surface of the positive electrode active material pattern layer.
- the positive electrode current collector may be a pipe-shaped current collector having a predetermined shape, or may be a mesh current collector having a predetermined shape.
- the positive electrode current collector may be a wire-type current collector wound on the outer surface of the positive electrode active material pattern layer.
- the current collector is a surface treated with carbon, nickel, titanium, silver on the surface of stainless steel, aluminum, nickel, titanium, calcined carbon, copper or stainless steel, vision treated with aluminum-cadmium alloy, conductive material
- conductive material It is preferable to use a conductive polymer or a conductive polymer.
- Such conductive materials may include polyacetylene, polyaniline, polypyrrole, polythiophene and polysulfuride, ITO (Indum Thin Oxide), silver, palladium and nickel, and the conductive polymer may be polyacetylene, polyaniline, polypyrrole, polythiol Offen, polysulfuritride and the like can be used.
- the active material layer is a negative electrode active material pattern layer; natural graphite, artificial graphite, carbonaceous material; Metals (Me) that are lithium-containing titanium composite oxide (LTO), Si, Sn, Li, Zn, Mg, Cd, Ce, Ni, or Fe; Alloys composed of the metals (Me); Oxides of the metals (Me) (MeOx); And composites of the metals (Me) and carbon, and the like.
