General description

Differential thermal analysis of germanium (II) sulfide was investigated. Melting point of GeS is 665oC. GeS nanoparticles may be prepared by gas phase laser photolysis, to be used in lithium ion batteries. GeS films may be generated by electrochemical deposition and used as an electrolyte. A study also reports the formation of GeS clusters by laser ablation.

Strategies to enhance ionic conductivities in solid electrolytes typically focus on the effects of modifying their crystal structures or of tuning mobile-ion stoichiometries. A less-explored approach is to modulate the chemical bonding interactions within a material to promote fast lithium-ion
