- Abstract
- The coupling of composite polymer electrolytes (CPEs) with Se/C cathodes was achieved in this study to address the needs of modern solid-state lithium batteries, including high-energy density, low temperature (30 degrees C) operation, electrochemical stability, and ease of manufacture. Our solid-state Li-Se battery exhibited exceptional rate performance at 30 degrees C and even surpassed contemporary solid-state Li-S batteries, which operate at elevated temperatures, in terms of performance. Excellent battery performance was exemplified by a sustained capacity of 250 mA h g-1 over 200 cycles at 2C. We also fabricated pouch-type solid-state Li-Se batteries using CPEs and demonstrated their ease of manufacture relative to previous solid-state Li-Se batteries. This paper presents a promising approach for advancing all-solid-state batteries through the synergistic utilization of CPEs and Li-Se chemistry. The coupling of composite polymer electrolytes with Se/C cathodes was achieved in this study to address the needs of modern solid-state batteries, including high-energy density, low temperature operation, cycle stability, and ease of manufacture.
