The present invention includes a solid electrolyte for a lithium battery, which includes a compound of formula Li_(1+X)A_XB_(2-X)(PO_4)_3, and B_2O_3 or Bi_2O_3 as sintering aid. In the formulas, A is at least one material selected from a group consisting of aluminum (Al), chromium (Cr), gallium (Ga), iron (Fe), scandium (Sc), indium (In), lutetium (Lu), yttrium (Y), and lanthanum (La), B is at least one material selected from a group consisting of titanium (Ti), germanium (Ge), and zirconium (Zr), and X has a value of 0.1 to 0.5. According to the present invention, in an oxide-based lithium ion conductive solid electrolyte, B_2O_3 and Bi_2O_3 are added as the sintering additive to lower the sintering temperature, increase the density of the sintered body, and decrease the grain boundary resistance, thereby improving the lithium ion conductivity. This enables high output and high performance of the lithium battery. COPYRIGHT KIPO 2017 (AA) Embodiment 1 (BB) Embodiment 2 (CC) Embodiment ...

The present invention relates to a method for improving long-term deterioration and strength stability of a Ni-YSZ anode support through an addition of Al_2O_3. In particular, the strength of a Ni-3YSZ is remarkably reduced compared to the strength of a Ni-8YSZ after a long-time operation under an acceleration anode operation condition of SOFC, and a formation of a new monoclinic crystal system phase of a Ni-3YSZ cermet leading to degradation of the bending strength of the anode support is caused. An addition of 1 to 5 wt% of Al_2O_3 prevents a formation of a new phase of a Ni-3YSZ anode support during a long-term operation. Also, mechanical strength and structural stability are improved. Thus, to stably replace a Ni-8YSZ as an anode support of SOFC, the present invention can be useful in producing a Ni-3YSZ cermet having improved long-term deterioration and strength stability.
