Iyo yakakwirira-yakareba-yakareba-yakareba solar isina munhu aerial mota (EAV-3) yakagadziridzwa neKorea Aerospace Research Institute, yakatakura LG Chem’s lithium-sulfur mabhatiri, yakabudirira kuita stratospheric bvunzo yekubhururuka.

The stratosphere ndiyo mhepo iri pakati petroposphere (surface kusvika 12 km) uye yepakati layer (50 kusvika 80 km), ine hurefu hwe12 kusvika 50 km.

EAV-3 indege diki inokwanisa kubhururuka kwenguva yakareba kuburikidza nesimba rezuva uye mabhatiri ari mu stratosphere pakureba kwe12km kana kudarika. Shandisa solar panel pamapapiro kuchaja, bhururuka nemaseru ezuva uye simba rebhatiri masikati, uye bhururuka nemabhatiri akachajwa masikati usiku. Iyo EAV-3 ine mapapiro akareba 20m uye fuselage ye9m.

Muyedzo iyi yekubhururuka, EAV-3 yakaisa rekodhi yakakwirira mukubhururuka kwe stratospheric yeKorea drones yemumba ine kukwira kwe 22km. Munguva yekubhururuka kwemaawa gumi nematatu, iyo UAV yakaita kubhururuka kwakadzikama kweanosvika maawa manomwe mustratosphere pakakwirira 13km kusvika 7km.

Lithium-sarufa mabhatiri, seimwe yechizvarwa chitsva mabhatiri kutsiva lithium mabhatiri, shandisa zvinhu zvakareruka senge sulfur-carbon composite cathode zvinhu uye lithium metal anode zvinhu, uye simba ravo remagetsi payuniti huremu hunopfuura ka1.5 pane yelithium iripo. mabhatiri. Chakanakira ndechekuti yakareruka pane iripo lithium bhatiri uye ine mutengo uri nani kukwikwidza nekuti haishandise simbi isingawanzo.

LG Chem yakati mune ramangwana ichagadzira yakawanda lithium-sarufa bhatiri yekuedza zvigadzirwa uye kuita akawanda-mazuva ekureba bvunzo dzendege. Inorongawo kugadzira mabhatiri e-lithium-sarufa ane simba rinopfuura kaviri mabhatiri e-lithium aripo mushure me2025.
