LG Chem iri kuyedza lithium-sarufa (Li-S) masero. "Serial kugadzirwa pashure 2025"

Isu tinosanganisa LG Chem kunyanya neiyo classic lithium-ion maseru ayo anoshandiswa zvakanyanya mumotokari dzemagetsi. Nekudaro, iyo kambani iri kuyedza nedzimwe mhinduro senge lithium sulfur masero. Zvigumisiro zvinovimbisa, kugadzirwa kwehuwandu kunogoneka muhafu yechipiri yemakore gumi.

Mota yemuchadenga isina munhu ine Li-S bhatiri inotyora rekodhi rendege mu stratosphere

Sangano reSouth Korea Institute for Airspace Research rakagadzira EAV-3 isina munhu anofamba nendege mota. Inoshandisa masero matsva eLi-S akagadzirwa ne LG Chem. Munguva yekuedza kwemaawa gumi nematatu inofambiswa neEAV-13 mabhatiri, yakabhururuka kwemaawa manomwe mu stratosphere pahupamhi hwemakiromita gumi nemaviri kusvika makumi maviri nemaviri. Nokudaro, akaputsa rekodhi yehupamhi hwekubhururuka kwemotokari yemhepo isina munhu (mabviro).

Classic lithium-ion masero ane graphite kana graphite anode akaiswa nesilicon. Masero eLi-S akagadzirwa ne LG Chem anobva pane kabhoni sulfur anodes. Isu takangodzidza nezve macathodes anoshandisa lithium, saka anogona kuve NCM cathodes. Mugadziri haana kuzivisa mamwe ekuwedzera tekinoroji paramita yemasero, asi akati nekuda kwekushandiswa kwesarufa (gravimetric), kuwanda kwesimba remasero "kupfuura 1,5 times yakakwirira" kupfuura iyo yelithium-ion masero.

Iyi ishoma ye 0,38 kWh / kg.

LG Chem yakazivisa kuti ichagadzira itsva cell prototypes inogona kugonesa ndege kwemazuva akati wandei. Nokudaro, zviri nyore kugumisa kuti mugadziri haasati agadzirisa dambudziko rekuparara kwesarufa mu electrolyte uye kukurumidza kuparara kwebhatiri yeLi-S - pakanga pane photocells pamapapiro, saka pakanga pasina kushayikwa kwesimba.

Zvisinei neizvi Iyo kambani inotarisira kugadzirwa kwakawanda kwe lithium sulfur masero kutanga mushure me2025.... Vachave nemasimba emagetsi akapetwa kaviri emasero e-lithium-ion.
