Abstract
A sulfide-based crystallized glass for an all-solid secondary battery has a sulfide that includes Li2S and P2S5, wherein the sulfide-based crystallized glass consists of 1 to 5% by mole of Li3BO3. A method for manufacturing the sulfide-based crystallized glass comprises steps of mixing (1) 75 to 80% by mole of Li2S and 20 to 25% by mole of P2S5, and then mixing (2) 95 to 99% by mole of obtained mixture at (1) and 1 to 5% by mole of Li3BO3 with a mechanical milling method, and subjecting the mixture thus obtained to a heat-treatment process.
