LATP All solid state battery having LATP-containing cathode electrode composite and manufacturing method the same

摘要

Various embodiments of the present invention are directed to a pre-solid battery and a method of manufacturing the same, and a technical problem to be solved is to provide a pre-solid battery having a LATP-containing cathode composite and a method of manufacturing the same. To this end, the present invention provides a positive electrode composite material comprising a positive electrode active material, a positive electrode composite material formed by applying a positive electrode active material slurry including an ion conductive LATP (Li _a Al _b Ti _c P _d O ₁₂ ), a conductive material and an ion conductive binder on a positive electrode collector; A solid electrolyte formed by applying a solid electrolyte slurry including an ion conductive LLZO (Li _x La _y Zr _z O ₁₂ ), an ion conductive binder and a lithium sa And a negative electrode material, wherein the positive electrode composite material is adhered to one surface of the solid electrolyte and the negative electrode material is adhered to the other surface thereof, wherein a = 1 to 2 mole, b = 0.1 to 0.5 mole, c = 1 to 2 mole , d = 1 to 4 moles, x = 6 to 9 moles, y = 2 to 4 moles, z = 1 to 3 moles, and a process for producing the same.
