I-CATL iyamangalisa. Wethula amaseli e-Na-ion (sodium-ion) kanye nebhethri elisekelwe kuwo
I-CATL yaseShayina izidla ngesizukulwane sokuqala samaseli e-sodium-ion kanye nebhethri lesibonelo elinikwa amandla yiwo. Izikhungo zocwaningo ezehlukene bezilokhu zethula izinguqulo zokuqala zamaseli iminyaka eminingana, futhi i-CATL ifuna ukwethula uchungechunge lokuhlinzeka ngokukhiqizwa kwawo ngo-2023. Ngakho-ke, uhlose ukuzilungiselela ukukhiqizwa ngobuningi futhi azilethe emakethe.
Izakhi ze-Lithium-ion kanye ne-Na-ion (Na+) enguqulweni ye-CATL
Amaseli e-sodium-ion - ngokusobala - esikhundleni se-lithium, asebenzisa elinye ilungu leqembu le-alkaline, i-sodium (Na). I-sodium ingenye yezinto ezitholakala ngobuningi obukhulu oqweqweni lomhlaba, itholakala nasemanzini olwandle futhi kulula kakhulu ukuyithola kune-lithium. Ngenxa yalokho, amaseli e-Na-ion ashibhile ukuwakhiqiza.okungenani uma kuziwa ezintweni zokusetshenziswa.
Kodwa i-sodium nayo inezinkinga zayo. Ngokusho kwe-CATL, amandla athile ezakhi ze-sodium-ion afinyelela ku-0,16 kWh / kg ngakho-ke, cishe ingxenye yamaseli e-lithium-ion angcono kakhulu. Ngaphezu kwalokho, ukusetshenziswa kwe-sodium kusho ukuthi "izidingo eziqinile" kufanele zisebenze ekwakhiweni nasekuziphatheni kwamaseli. Lokhu kungenxa yobukhulu be-sodium ion, eyi-1/3 emikhulu kune-ion ye-lithium ngakho-ke iphusha i-anode ihlukane kakhulu - ukuvimbela ukulimala kwe-anode, i-CATL yakha i-anode "eqinile" enezimbobo.
Isizukulwane esisha samaseli e-CATL Na-ion ukuminyana kwamandla ka-0,2 kWh/kg noma ngaphezulu kulindeleke ukuthi kuzuzwe, bazoqala ukunyathela ezithendeni ze-lithium iron phosphate (LiFePO4). Kakade amaseli e-sodium ion bashaja amaphesenti angaba ngu-80 ngemizuzu engu-15okuwumphumela omuhle kakhulu - amaseli e-lithium-ion atholakala kakhulu kwezohwebo asezingeni lemizuzu engu-18, futhi kuma-laboratories kwakungenzeka ukunciphisa leli nani.
Ubuchwepheshe bokukhiqiza amaseli e-Na-ion kumele buhambisane nobuchwepheshe obaziwa ngamaseli e-lithium-ion.Ngakho, imigqa yokukhiqiza ingaguqulwa isuka ku-sodium iye ku-lithium, amanothi e-CATL. Ama-elementi amasha kufanele futhi abe nokusebenza okungcono emazingeni okushisa aphansi futhi ahlukahlukene, ku -20 degrees Celsius kumele bagcine amaphesenti angama-90 (!) omthamo wabo wokuqalaNgaleso sikhathi, amabhethri e-LFP ngaphansi kwalezi zimo anamaphesenti angama-30 kuphela amandla awo lapho evivinywa ekamelweni lokushisa.
I-CATL yethule ibhethri elisuselwe kumaseli e-Na-ion futhi ayifaki ngaphandle ukuthi izoletha izixazululo eziyingxube emakethe esikhathini esizayo. Inhlanganisela yamaseli e-Li-Ion ne-Na-Ion ephaketheni elilodwa izokuvumela ukuthi usebenzise kokubili izixazululo, kuye ngezimo ezikhona.
Inothi lomhleli www.elektrowoz.pl: I-prototype yokuqala yamaseli e-Na-ion avaliwe kumaphakheji wezohwebo angu-18650 aboniswe yi-French Atomic Energy and Alternative Energy Committee CEA ngo-2015 (umthombo). Babenamandla amakhulu angu-0,09 kWh/kg.
Lokhu kungase kube nentshisekelo kuwe:
