LITHIUM SULFIDE
FUNCTIONAL SULFIDE MATERIALS
Lithium sulfide is being researched and developed as a solid electrolyte material for all-solid-state
lithium ion batteries and a negative electrode material of high-capacity lithium batteries, and Nippon
Chemical Industrial Co., Ltd. provides lithium sulfide to many universities, public research institutes,
and private enterprises. The company has added various improvements and achieved:
(1) a uniform shape and particle size by increasing crystallinity;
(2) reduced impurity metals by use of high-purity raw materials; and
(3) reduced sulfur oxide concentration by highly controlled manufacturing conditions.
