LG Chem e hlahloba lisele tsa lithium-sulfur (Li-S). "Serial tlhahiso ka mor'a 2025"

Re amahanya LG Chem haholo-holo le lisele tsa lithium-ion tsa khale tse sebelisoang haholo likoloing tsa motlakase. Leha ho le joalo, k'hamphani e ntse e leka litharollo tse ling tse kang lithium sulfur cell. Liphello li tšepisa, tlhahiso ea bongata e ka khoneha karolong ea bobeli ea lilemo tse leshome.

Koloi e sa sebetsoang ea sefofane e nang le betri ea Li-S e roba rekoto ea sefofane sebakeng sa stratosphere

South Korea Institute for Airspace Research e thehile EAV-3 e sa sebetsoeng ea sefofane. E sebelisa lisele tse ncha tsa Li-S tse entsoeng ke LG Chem. Nakong ea teko ea lihora tse 13 e tsamaisoang ke libeteri tsa EAV-3, e ile ea fofa lihora tse 7 sebakeng sa stratosphere sebakeng sa 12 ho ea ho 22 km. Ka hona, o ile a roba tlaleho ea bophahamo ba sefofane sa sefofane se se nang motho (mohloli).

Lisele tsa khale tsa lithium-ion li na le graphite kapa graphite anode e kentsoeng ka silicon. Lisele tsa Li-S tse entsoeng ke LG Chem li thehiloe ho li-anode tsa carbon sulfur. Re ithutile feela ka li-cathodes tse sebelisang lithium, kahoo li ka ba li-cathodes tsa NCM. Moetsi ha aa ka a senola mekhoa e meng ea tekheniki ea lisele, empa a re ka lebaka la tšebeliso ea sebabole (gravimetric), matla a matla a lisele "a phahame ka makhetlo a 1,5" ho feta a lisele tsa lithium-ion.

Sena ke bonyane ba 0,38 kWh / kg.

LG Chem e phatlalalitse hore e tla theha li-prototypes tse ncha tsa lisele tse ka matlafatsang sefofane ka matsatsi a 'maloa. Ka hona, ho bonolo ho etsa qeto ea hore moetsi ha a e-s'o rarolle bothata ba ho qhibiliha ha sebabole ka electrolyte le ho senyeha ka potlako ha betri ea Li-S - ho ne ho e-na le li-photocells mapheong, kahoo ho ne ho se na khaello ea matla.

Leha ho le joalo Khamphani e lebelletse hore tlhahiso e kholo ea lisele tsa lithium sulfur e tla qala kamora 2025.... Ba tla ba le matla a matla a makhetlo a mabeli a lisele tsa lithium-ion.
