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

摘要

Various embodiments of the present invention relate to an all-solid-state battery and a method for manufacturing the same. The present invention is to provide an all-solid-state battery having a LATP-containing positive electrode composite and a method for manufacturing the same. The all-solid-state battery comprises: a positive electrode composite formed by applying positive electrode active material slurry, comprising a positive electrode active material, ion conductive LATP (Li_aAl_bTi_cP_dO_12), a conductive material, and an ion conductive binder, on a positive electrode collector; solid electrolyte formed by applying solid electrolyte slurry comprising ion conductive LLZO (Li_xLa_yZr_zO_12), an ion conductive binder, and lithium sa and a negative electrode material. The positive electrode composite is attached to one side with respect to the solid electrolyte as a center. The negative electrode material is attached to the other side. In the present invention, disclosed are an all-solid-state battery having an LATP-containing positive electrode composite and a method for manufacturing the same, wherein a = 1-2 moles, b = 0.1-0.5 moles, c = 1-2 moles, d = 1-4 moles, x = 6-9 moles, y = 2-4 moles, and z = 1-3 moles.
