Characterization of all-solid-state lithium secondary batteries using CuxMo6S8−y electrode and Li2S–P2S5 solid electrolyte

Issues and Challenges for Bulk‐Type All‐Solid‐State Rechargeable Lithium Batteries using Sulfide Solid Electrolytes

“…In particular, TiS 2 14b,f and Li x TiS 2 65 were reported to show good cycling performance in ASLBs, with reversible capacities close to the theoretical one (TiS 2 +Li + +e − ↔LiTiS 2 , 239 mA h g −1 ). The Chevrel‐phase compound, (Cu x )Mo 6 S 8− y , also exhibited excellent cycle life in ASLBs 5b,c. The outstanding performance of TiS 2 and (Cu x )Mo 6 S 8− y is associated with their metallic nature, their reversible intercalation/deintercalation, high Li + ion diffusivity, and so on 5b,c,14b,f,65.…”

Ceramic and polymeric solid electrolytes for lithium-ion batteries

“…Li 2 S-P 2 S 5 -Li 4 SiO 4 [10]), crystallization decreases conductivity. Sulfide electrolytes have been used in batteries with lithium-indium anodes and several different cathodes, including sulfides of nickel [13,14], copper [15] and copper-molybdenum [16], which operate at potentials of 2-3 V vs. Li/Li + . Sulfide electrolytes have also been used in batteries with a NiP 2 cathode [17], which operates at a lower potential, as well as with more widely used cathodes, including LiCoO 2 [18][19][20] and Li 4 Ti 5 O 12 [21,22].…”

Formation and structure of Na2S + P2S5 amorphous materials prepared by melt-quenching and mechanical milling

“…Subsequently, all-solid-state cells using a high conductivity glass-ceramic Li 2 S + P 2 S 5 solid electrolyte have been fabricated. Some cells have shown good cycleablity up to two thousand cycles [12][13][14].…”
