“…17 Highly ordered mesoporous carbon consists of a carbon matrix arranged with regularly patterned mesopores. [18][19][20][21][22][23] This kind of carbon was synthesized by using an ordered mesoporous silica template coated on a carbon precursor. CMK-3, which is synthesized by using rod-shaped silica SBA-15 as the template, has stacks of hollow rod-shaped pores.…”

The electrochemical properties of a lithium air secondary battery (LAB) cell incorporating CMK-3 or carbon replica (CR) as a highly ordered mesoporous carbon support material were examined under the condition of a current density of 0.1 mA/cm 2 with a voltage range of 2.0 to 4.2 V in a dry air atmosphere. The first discharge capacities of the LAB cell incorporating Pt 10 Ru 90 electrocatalyst/CMK-3 and CR were 103 and 1000 mAh/g, respectively. The cycle properties of the LAB cell incorporating Pt 10 Ru 90 electrocatalyst/CMK-3 was poor; in contrast, the one incorporating CR showed better cycle stability (828 mAh/g up to 9 cycles). These superior properties with CR are due to its larger surface area and larger total pore volume than those of CMK-3.

“…Flat voltage regions were observed around 1.7 and 2.3 V (vs. Li-Al) during discharging and charging, respectively, indicative of the reversible reaction of sulfur with lithium in the composites. 4,20 Additional reactions were confirmed at around 1.2 V for milling times of 300 and 600 min, indicative of a reaction of carbon and/or the solid electrolyte material with lithium. 4,18,23 The composite milled for 10 min exhibited a low 1st discharge capacity of approximately 550 mAh g ¹1 , which is less than half of the theoretical capacity of sulfur.…”

“…To evaluate the cyclability of the battery, the low-voltage Li-Al anode was replaced with a Li-In anode to eliminate unexpected reactions (e.g., that between carbon and lithium) and to prevent the decomposition of SE in the low voltage region. 4,20,23 In addition to this change, cut-off voltage of discharge process was slightly increased. The cut-off voltage of 0.73 V (vs. Li-In: 1.33 V vs. Li) was selected instead of 1.0 V (vs. Li-Al: 1.30 V vs. Li).…”

Composite sulfur electrodes are prepared by prolonged mechanical milling (;300 min) for use in all-solid-state lithium-sulfur batteries, and their structure and electrochemical properties are investigated. These batteries exhibit a high initial discharge capacity (>1500 mAh g −1). Sulfur, acetylene black, and the solid electrolyte Li 3.25 -Ge 0.25 P 0.75 S 4 are mixed by planetary ball milling to form composites that contain amorphous phases of the starting materials, as well as a byproduct with a novel structural unit arising from the reaction between sulfur and the solid electrolyte. Batteries with a composite electrode/Li 3.25 Ge 0.25 P 0.75 S 4 /Li-In anode configuration exhibit a high initial discharge capacity (>1100 mAh g −1). However, the capacity fades during cycling (~500 mAh g −1 at the 30th cycle), possibly because of the increased resistance of the composite. Structural and compositional changes of the byproduct and the solid electrolyte itself during the battery reaction could contribute to the increase in resistance that cause the deterioration of cyclability.
