Jirgin sama mai tsayin tsayin daka mai amfani da hasken rana mara matuki (EAV-3) wanda cibiyar binciken sararin samaniyar kasar Koriya ta ƙera, wanda ke ɗauke da batir lithium-sulfur na LG Chem, ya yi nasarar yin gwajin jirgin sama na stratospheric.

Stratosphere shine yanayin da ke tsakanin troposphere (surface zuwa kilomita 12) da tsakiyar Layer (kilomita 50 zuwa 80), tare da tsayin kilomita 12 zuwa 50.

EAV-3 karamin jirgin sama ne wanda zai iya tashi na dogon lokaci ta hanyar makamashin hasken rana da batura a cikin stratosphere a tsayin kilomita 12 ko fiye. Yi amfani da na’urorin hasken rana a kan fuka-fuki don yin caji, tashi da ƙwayoyin hasken rana da ƙarfin baturi a rana, da kuma tashi tare da cajin batir da rana da dare. EAV-3 yana da tsawon fuka-fuki na 20m da fuselage na 9m.

A cikin wannan gwajin jirgin, EAV-3 ya kafa tarihi mai tsayi a cikin jirgin da ba a sarrafa ba na cikin gida na Koriya mai tsayin kilomita 22. A cikin jirgin na sa’o’i 13, UAV ta gudanar da wani tsayayyen jirgi na tsawon sa’o’i 7 a cikin stratosphere a tsayin kilomita 12 zuwa 22km.

Batirin Lithium-sulfur, a matsayin daya daga cikin sabbin batura don maye gurbin baturan lithium, suna amfani da kayan haske irin su sulfur-carbon composite cathode kayan da lithium karfe anode, kuma yawan kuzarinsu na kowace naúrar ya fi sau 1.5 fiye da na lithium da ake da su. baturi. Amfanin shi ne cewa ya fi batirin lithium da ke da wuta wuta kuma yana da mafi kyawun gasa saboda baya amfani da ƙananan karafa.

LG Chem ya ce nan gaba za ta samar da karin kayayyakin gwajin batirin lithium-sulfur tare da gudanar da gwaje-gwajen jiragen sama na tsawon kwanaki da dama. Har ila yau, tana shirin samar da manyan batura na lithium-sulfur tare da yawan makamashi fiye da sau biyu na batirin lithium da ake dasu bayan 2025.
