I-LG Chem ihlola amaseli e-lithium-sulfur (Li-S). "Ukukhiqizwa kwe-serial ngemuva kuka-2025"

Sihlobanisa i-LG Chem ikakhulukazi namaseli e-lithium-ion asetshenziswa kakhulu ezimotweni zikagesi. Kodwa-ke, inkampani izama ezinye izixazululo ezifana namaseli e-lithium sulphur. Imiphumela iyathembisa, ukukhiqizwa ngobuningi kungenzeka engxenyeni yesibili yeshumi leminyaka.

Imoto yasemoyeni engenamuntu enebhethri ye-Li-S yephula irekhodi lendiza ku-stratosphere

I-South Korean Institute for Airspace Research idale i-EAV-3 yendiza engenamuntu. Isebenzisa amaseli e-Li-S amasha athuthukiswe yi-LG Chem. Ngesikhathi sokuhlolwa kwamahora angu-13 okunikwa amandla amabhethri e-EAV-3, indize amahora angu-7 ku-stratosphere endaweni ephakeme yamakhilomitha angu-12 kuya kwangu-22. Ngakho-ke, wephula irekhodi lokuphakama kokundiza kwemoto yasemoyeni engenamuntu (umthombo).

Amaseli e-lithium-ion akudala ane-graphite noma ama-graphite anode ahlanganiswe ne-silicon. Amaseli e-Li-S athuthukiswe yi-LG Chem asuselwa ku-carbon sulphur anode. Sifunde kuphela ngama-cathodes asebenzisa i-lithium, ngakho-ke angaba ama-NCM cathodes. Umkhiqizi akazange adalule noma yimiphi eminye imingcele yezobuchwepheshe yamaseli, kodwa wathi ngenxa yokusetshenziswa kwesulfure (i-gravimetric), ukuminyana kwamandla amaseli "kungaphezu kwezikhathi ezingu-1,5" kunamaseli e-lithium-ion.

Lokhu ubuncane be-0,38 kWh / kg.

I-LG Chem imemezele ukuthi izodala ama-cell prototypes amasha angakwazi ukunika amandla indiza izinsuku ezimbalwa. Ngakho-ke, kulula ukuphetha ngokuthi umenzi akakayixazululi inkinga yokuchithwa kwesibabule ku-electrolyte kanye nokuwohloka okusheshayo kwebhethri ye-Li-S - kwakukhona ama-photocells emaphikweni, ngakho kwakungekho ukushoda kwamandla.

Ngaphandle kwalokhu Inkampani ilindele ukukhiqizwa ngobuningi kwamaseli e-lithium sulphur kuqale ngemuva kuka-2025.... Bazoba namandla aphindwe kabili kunamaseli e-lithium-ion.
