Abstract
The 80SnS·20P2S5 (mol%) amorphous material was prepared by a mechanical milling technique. The obtained material was fine powders with a few micrometers in size. All-solid-state cells with the SnS-P2S5 amorphous electrode and the Li2S-P2S5 glass-ceramic electrolyte, where a continuous P2S5 sulfide network between both the materials was formed, were fabricated. The cells exhibited high reversible capacity of over 400 mAh gâ1 for 50 cycles at room temperature. The addition of P2S5 as a glass former to SnS improved cell capacity and cyclability, suggesting that P2S5 network played an important role in enhancing the availability of SnS as an electrode material.
