Imoto yasemoyeni enobude obuphakeme yelanga engaphethwe muntu (EAV-3) enobude obuphakeme eyakhiwe yi-Korea Aerospace Research Institute, elayishwe amabhethri e-LG Chem e-lithium-sulphur, yenze ngempumelelo ukuhlolwa kwendiza ye-stratospheric.

I-stratosphere ingumkhathi ophakathi kwe-troposphere (ubuso obungamakhilomitha angu-12) kanye nongqimba oluphakathi (50 kuya ku-80 km), nokuphakama kwe-12 kuya ku-50 km.

I-EAV-3 iyindiza encane ekwazi ukundiza isikhathi eside ngamandla elanga namabhethri ku-stratosphere ubude obungu-12km noma ngaphezulu. Sebenzisa amaphaneli elanga ezimpikweni ukuze ushaje, undize ngamaseli elanga namandla ebhethri phakathi nosuku, futhi undize namabhethri ashajwe emini ebusuku. I-EAV-3 inamaphiko angama-20m kanye nefuselage engu-9m.

Kulolu vivinyo lwendiza, i-EAV-3 iqophe irekhodi eliphezulu endizeni ye-stratospheric yama-drones asekhaya ase-Korea enobude bendiza obungu-22km. Phakathi nohambo lokundiza lwamahora angu-13, i-UAV yenze indiza ezinzile amahora afinyelela kwangu-7 endaweni eyi-stratosphere endaweni ephakeme engu-12km kuya ku-22km.

Amabhethri e-lithium-sulfur, njengelinye lamabhethri esizukulwane esisha athatha indawo yamabhethri e-lithium, asebenzisa izinto ezilula ezifana nezinto ze-sulphur-carbon composite cathode nezinto ze-lithium metal anode, futhi ukuminyana kwawo kwamandla ngeyunithi ngayinye isisindo singaphezu kwezikhathi ezingu-1.5 kune-lithium ekhona kakade. amabhethri. Inzuzo ukuthi ilula kunebhethri ye-lithium ekhona futhi inokuncintisana okungcono kwentengo ngoba ayisebenzisi izinsimbi ezingavamile.

I-LG Chem ithe ngokuzayo izokhiqiza imikhiqizo eminingi yesilingo sebhethri ye-lithium-sulphur futhi yenze ukuhlolwa kwendiza yezinsuku eziningi zebanga elide. Iphinde ihlele ukukhiqiza ngobuningi amabhethri e-lithium-sulphur ane-energy density ngaphezu kokuphindwe kabili kwamabhethri e-lithium akhona ngemuva kuka-2025.
