Lithium sulfide Li₂S |Li₂S+GeS₂+P₂S₅/ Ndi₂S+SiS₂+Al₂S₃

Kufotokozera

Lithium sulfide Li₂S 3n4n(99.9%, 99.99%) ndi kristalo woyera wachikasu, CAS 12136-58-2, MW 45.95, kachulukidwe 1.66g/cm³, malo osungunuka 938 ° C, kuwira kwa 1372 ° C, amachitira mwamphamvu ndi madzi ndi sungunuka m'madzi, Mowa ndi asidi koma osasungunuka mu alkali.Lithium Sulfide ilipo mu mitundu iwiri ya orthorhombic ndi cubic structure yokhala ndi kachulukidwe ka 1.75g/cm.³ndi 1.63g/cm³motsatira.Kukhala anti-fluorite compound semiconductor ndi cubic Li₂S an indirect band-gap semiconductor ya 3.865 eV,Lithium sulfidendiopangidwa mwapadera kuti agwiritse ntchito mabatire apamwamba pomwe atha kugwiritsidwa ntchito ngati zinthu za electrode kapena ngati kalambulabwalo wa ma electrolyte olimba.Poyerekeza ndi organic madzi kapena gel electrolyte, olimba electrolyte Lithium Sulfide ali ndi ubwino mkulu chitetezo, bata matenthedwe ndi electrochemical bata, lalikulu lithiamu ion conductivity ndi otetezeka mu osiyanasiyana voteji.

Mapulogalamu

Lithium sulfide Li₂S ndi Li₂S+GeS₂+ P₂S₅ ndi Li₂S+SiS₂+ Al₂S₃ amaonedwa ngati zingamuthandize cathode zakuthupi otetezeka mphamvu yosungirako maselo, amene ali ndi moyo wautali, voliyumu mkulu ndi makhalidwe mkulu mphamvu, ndipo adzakhala azimuth azimuth zinthu electrolyte mu rechargeable mabatire lifiyamu-ion, mphira galasi, mikangano zida ndi kuwala. ndi zipangizo zamagetsi zotetezeka ndi zina. Sulfide Solid Electrolytes Lithium Sulfur Li₂S ndi Li₂S+GeS₂+ P₂S₅ ndi Li₂S+SiS₂+ Al₂S₃akukulanso gawo lofunikira la dongosolo lamphamvu lamphamvu lamagetsi ndi zida zosungiramo mphamvu zankhondo, galimoto yamagetsi, sitima yapamadzi ndi ndege.
