Title of invention: Cylindrical secondary battery including piezoelectric element and thermoelectric element Technical field [One] This application claims the benefit of priority based on Korean Patent Application No. 10-2018-0152912 filed on November 30, 2018, and all contents disclosed in the documents of the Korean patent application are included as part of this specification. [2] The present invention relates to a cylindrical secondary battery including a piezoelectric element and a thermoelectric element. Background [3] Recently, interest in energy source prices and environmental pollution are amplified due to depletion of fossil fuels, and the demand for eco-friendly alternative energy sources is becoming an indispensable factor for future life. Accordingly, research on various power generation technologies such as nuclear power, solar power, wind power, and tidal power continues, and a power storage device for more efficient use of the energy produced in this way is also drawing great interest. [4] Moreover, as technology development and demand for mobile devices and battery vehicles increase, the demand for batteries as an energy source is rapidly increasing, and accordingly, many studies on batteries that can meet various demands are being conducted. In particular, in terms of materials, there is a high demand for lithium secondary batteries such as lithium ion batteries and lithium ion polymer batteries having advantages such as high energy density, discharge voltage, and output stability. [5] Secondary batteries are classified according to the structure of an electrode assembly in which a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode are stacked. Typically, a jelly-roll type (wound type) electrode assembly in which a long sheet-shaped anode and cathode are wound with a separator interposed therebetween. Stacked (stacked) electrode assemblies that are sequentially stacked. Recently, in order to solve problems with the jelly-roll type electrode assembly and the stack type electrode assembly, As an electrode assembly having an advanced structure, a stack/folding type electrode assembly having a structure in which unit cells in which a predetermined unit of anodes and cathodes are stacked with a separator interposed therebetween are sequentially wound on a separation film has been developed. [6] According to the purpose of use, such electrode assemblies are accommodated in a pouch case, a cylindrical can, and a square case to manufacture a battery. [7] Among them, cylindrical batteries are easy to manufacture and have high energy density per weight, so they are used as energy sources for various devices ranging from portable computers to battery vehicles. In order to make the most of the energy density advantage, the content of silicon is increased in the negative active material. At this time, silicon is greatly expanded in volume during the charging and discharging process of the battery, which generates a lot of stress inside the battery during the repeated volume expansion process of the negative electrode. Compared to silicon, volume expansion is relatively small, but graphite also expands in volume and generates stress. In particular, there is a problem that the stress is concentrated in the stepped portion of the anode. [8] In addition, in the case of a high-density and high-capacity battery such as a cylindrical battery, a lot of thermal energy is generated during the charging and discharging process, and there is a problem in that it must be effectively controlled. [9] Therefore, there is a need for a technology that can fundamentally solve this problem. Detailed description of the invention Technical challenge [10] An object of the present invention is to solve the problems of the prior art and technical problems that have been requested from the past. [11] After in-depth research and various experiments, the inventors of the present application convert the stress generated by the expansion of the cathode into electrical energy by installing piezoelectric elements and thermoelectric elements on the anode tab, as described later, and use them. It was confirmed that heat energy could be controlled, and the present invention was completed. Means [12] The cylindrical secondary battery according to the present invention for achieving this purpose includes a positive electrode, a negative electrode, and a separator, the positive electrode includes a positive electrode tab, and a piezoelectric element and a thermoelectric element may be formed at the edges of the positive electrode tab. [13] The positive electrode tab may have a long rectangular strip shape compared to the width. [14] The piezoelectric element and the thermoelectric element may be formed on both edges of the anode tab in the longitudinal direction, respectively. [15] A storage space in which the piezoelectric element and the thermoelectric element can be installed may be formed at the edge. [16] The storage space may have a step shape. [17] Only the piezoelectric element may be formed at the edge. [18] The thermoelectric element may be formed in a central portion of the positive electrode tab. [19] In the central portion, a recessed portion having a structure recessed into the anode tab may be formed. [20] The thermoelectric element may be accommodated in the indentation. [21] Electrical energy generated by the piezoelectric element may be transferred to the thermoelectric element through an upper anode tab. [22] Two or more of the anode tabs may be formed on the anode. [23] The negative electrode is manufactured by coating and drying a negative electrode active material on a negative electrode current collector, and additional components may be optionally further included if necessary. [24] The negative electrode current collector is generally made to have a thickness of 3 to 500 micrometers. Such a negative electrode current collector is not particularly limited as long as it has conductivity without causing a chemical change in the battery, for example, copper, stainless steel, aluminum, nickel, titanium, calcined carbon, copper or stainless steel. Surface treatment with carbon, nickel, titanium, silver, etc., aluminum-cadmium alloy, and the like may be used. In addition, like the positive electrode current collector, it is possible to strengthen the bonding force of the negative electrode active material by forming fine irregularities on the surface thereof, and may be used in various forms such as films, sheets, foils, nets, porous bodies, foams, and nonwoven fabrics. [25] Examples of the negative active material include carbon such as non-graphitized carbon and graphite-based carbon; Li x Fe 2 O 3 (0≤x≤1), Li x WO 2 (0≤x≤1), Sn x Me 1-x Me' y O z (Me: Mn, Fe, Pb, Ge; Me' : Al, B, P, Si, elements of groups 1, 2, and 3 of the periodic table, halogens, metal complex oxides such as 0
