Provided are a core material for a vacuum insulation panel including porous aluminosilicate, and a vacuum insulation panel provided with the same. The core material for the vacuum insulation panel according to the present disclosure has superior long-term durability and improved gas adsorption ability (particularly, superior water absorption ability) while requiring a low raw material cost. The vacuum insulation panel including the core material may exhibit more improved insulation performance by minimizing a reduction in the vacuum degree without an additional getter or absorbent.

Provided are a method of preparing solid electrolyte particles of Chemical Formula 1 including preparing a precursor solution by mixing a titanium precursor, a lanthanum precursor, and a lithium precursor in an aqueous or organic solvent, and heat treating the precursor solution, solid electrolyte particles prepared thereby, and a lithium secondary battery including the solid electrolyte particles:LiLaTiO(0&#x3c;x&#x3c;0.16).&#x2003;&#x2003;&#x3c;Chemical Formula 1&#x3e; According to a method of preparing solid electrolyte particles according to an embodiment of the present invention, solid electrolyte particles may be easily prepared by heat treating at low temperature for a short period of time.

Solid electrolyte particles, preparation method thereof, and lithium secondary battery comprising the same

Provided are a secondary battery including a positive electrode, a negative electrode, and a solid electrolyte layer disposed between the positive electrode and the negative electrode, wherein the positive electrode and the negative electrode include first solid electrolyte particles, the solid electrolyte layer includes second solid electrolyte particles, and a particle diameter of the second solid electrolyte particles is greater than a particle diameter of the first solid electrolyte particles. In the secondary battery, the electrode may increase the amount of movement of lithium ions by increasing a contact area between the solid electrolyte particles and electrode active material, and the solid electrolyte layer may minimize the reduction of ionic conductivity by decreasing interfacial resistance due to the contact between the electrode and the solid electrolyte layer. Thus, stability and performance of the secondary battery may be improved.
