LG Chem imayesa ma cell a Lithium Sulfur (Li-S). "Kupanga kwakanthawi pambuyo pa 2025"
Timagwirizanitsa LG Chem makamaka ndi ma cell a lithiamu-ion omwe amagwiritsidwa ntchito kwambiri pamagalimoto amagetsi. Komabe, kampaniyo ikuyesera njira zina monga lithiamu-sulfure maselo. Zotsatira zikulonjeza, kupanga misala kumatheka mu theka lachiwiri la zaka khumi.
Galimoto yopanda ndege yokhala ndi batire ya Li-S imaphwanya mbiri ya ndege mu stratosphere
South Korea Institute for Airspace Research yapanga ndege ya EAV-3 yopanda munthu. Imagwiritsa ntchito maselo atsopano a Li-S opangidwa ndi LG Chem. Pakuyesa kwa maola 13 koyendetsedwa ndi mabatire a EAV-3, adawuluka maola 7 mu stratosphere pamtunda wa 12 mpaka 22 makilomita. Choncho, adaphwanya mbiri ya kutalika kwa ndege yopanda ndege (gwero).
Maselo apamwamba a lithiamu-ion ali ndi ma graphite kapena graphite anode okhala ndi silicon. Ma cell a Li-S opangidwa ndi LG Chem amachokera ku carbon sulfure anode. Tinangophunzira za ma cathodes omwe amagwiritsa ntchito lithiamu, kotero iwo akhoza kukhala NCM cathodes. Mlengi sanaulule zina zaumisiri magawo a maselo, koma ananena kuti chifukwa cha ntchito sulfure (gravimetric), mphamvu kachulukidwe maselo ndi "kuposa 1,5 nthawi apamwamba" kuposa maselo lifiyamu-ion.
Izi ndi zosachepera 0,38 kWh / kg.
LG Chem yalengeza kuti ipanga ma prototypes atsopano omwe amatha kuyendetsa ndege kwa masiku angapo. Choncho, n'zosavuta kunena kuti wopanga sanayambebe kuthetsa vuto la kusungunuka kwa sulfure mu electrolyte ndi kuwonongeka kwachangu kwa batri ya Li-S - panali photocells pamapiko, kotero panalibe kusowa kwa mphamvu.
Osatengera izi Kampaniyo ikuyembekeza kupanga ma cell a lithiamu sulfure kuyambika pambuyo pa 2025.... Adzakhala ndi mphamvu zochulukirapo kawiri kuposa maselo a lithiamu-ion.
Izi zingakusangalatseni:
