Title of invention: Lithium secondary battery containing inorganic electrolyte Technical field [One] The present invention relates to a lithium secondary battery including an inorganic electrolyte solution having improved high rate characteristics. [2] This application claims priority based on Korean Patent Application No. 10-2018-0081308 filed on July 12, 2018. Background [3] As technology development and demand for mobile devices increase, the demand for rechargeable, miniaturized, and large-capacity secondary batteries is rapidly increasing. In addition, lithium secondary batteries having a high energy density and voltage among secondary batteries have been commercialized and widely used. [4] A lithium secondary battery is generally manufactured by interposing two electrodes having different potentials and a separator for preventing an electrical short between the two electrodes, and then injecting an electrolyte for transferring lithium ions to the two electrodes. As an electrolyte for such a lithium secondary battery, a liquid electrolyte obtained by dissolving a lithium salt in an organic solvent is mostly used. [5] Meanwhile, in recent years, as safety issues such as ignition and explosion have been raised in critical situations such as high temperature and overcharging, the need for battery design that does not use flammable and flammable organic solvents has emerged. Phosphorus sulfur dioxide-based inorganic electrolytes are being actively researched. [6] In addition, the sulfur dioxide-based inorganic electrolyte is predicted to be advantageous in terms of high rate characteristics as it exhibits about 7 times higher ionic conductivity (about 78 to 80 mS/cm) than the organic electrolyte. [7] However, since the sulfur dioxide-based inorganic electrolyte does not have sufficient wettability for the hydrophobic carbon material negative electrode, which is mainly used for lithium secondary batteries, the diffusion rate of lithium ions is lowered. Since the insertion and discharge of the cells are not smooth, the charging and discharging efficiency may be lowered, and thus improvement thereof is required. [8] Detailed description of the invention Technical challenge [9] The present invention is to solve the above problems, and one object of the present invention is to provide a lithium secondary battery having improved high rate charge/discharge characteristics when a sulfur dioxide-based inorganic electrolyte is applied together with a carbon material negative electrode. [10] Means of solving the task [11] According to an aspect of the present invention, in the first aspect, the anode, the cathode, a separator interposed between the anode and the cathode, and a sulfur dioxide-based inorganic electrolyte are included, and the anode is a negative electrode active material with titanium oxide (TiO x , 0
