"Amaseli ethu e-aluminium-ion (i-aluminium-ion) ashaja izikhathi ezingu-60 ngokushesha kunamaseli e-lithium-ion." Hewu! :)

Iviki elisha, ibhethri elisha. Inkampani yase-Australia i-Graphene Manufacturing Group ithi ithuthukise amaseli asekelwe ku-graphene ne-aluminium (isici). Bathi "bashaja ngokushesha izikhathi ezingu-60 kunamaseli e-lithium ion angcono kakhulu" futhi "bangagcina amandla aphindwe kathathu kunamanye amaseli e-aluminium ion."

Amaseli e-Al-ion GMG. Konke kuzwakala kukuhle kakhulu

Uhlu lokuqukethwe

• Amaseli e-Al-ion GMG. Konke kuzwakala kukuhle kakhulu
  • I-Aluminium ishibhile, igraphene iyabiza

Amaseli e-GMG aluminium-ion kufanele abe sesimweni samaseli wezinkinobho, esiwazi ngokhiye noma amathoyizi amancane, isibonelo. Kodwa ukushaja ngokushesha izikhathi ezingamashumi ayisithupha kuzwakala emangalisayo. Une ngokwezibalo okokugcina kusuka emizuzwini engu-1 kuya kwengu-5. Ukuminyana kwamandla "iphindwe kathathu kunezinye izakhi ezinama-ion e-aluminium". 0,15-0,16 kWh/kg.

Le nkampani inenye ipharamitha: ikhono lokuthola amandla afinyelela ku-7 kW kusuka ku-1 kilogram yamaseli. Leyo amaseli emotweni kagesi eyisiboneloisisindo esingamakhilogremu angama-250, bangakhiqiza amandla afinyelela ku-1,75 MW (!, 2 km) wamandla ngesikhathi esiphezulu. Kuzwakala ku-cosmic, okungenani ephepheni. Uhlangothi olungemuva yi-voltage yokusebenza yeseli, okwamanje ingu-1,7 V.

Kusetshenziswa i-graphene, i-aluminium ion cell prototype eyakhiwe yi-GMG

Ekugcineni, ukukhulunywa kokusetshenziswa kwe-graphene kuzwakala kuthakazelisa, ngoba izixazululo ezinjalo sezivele zivele: i-graphene cathode yenza kwaba nokwenzeka ukufinyelela izinga le-0,2-0,3 kWh / kg futhi yenza kube nokwenzeka ukwenza amashumi noma ngisho namakhulu ezinkulungwane zomsebenzi. imijikelezo (!). Umbiko ovela eShayina uyathakazelisa ikakhulukazi, futhi ngenxa yokuba seduze kwe-Australia kanye nobudlelwano besayensi phakathi kwamazwe womabili. Nokho, iNyuvesi yaseZhejiang yakha iseli ye-aluminium ion cell eguquguqukayo, engashi ekwazi ukushaja ngemizuzwana engu-1,1 futhi igcine amaphesenti angu-91,7 omthamo wayo wangempela ngemva kwemijikelezo engu-250 (umthombo).

I-Aluminium ishibhile, igraphene iyabiza

Umsebenzi wamaseli e-aluminium ion ubulokhu uqhubeka iminyaka ngoba i-aluminium iyinsimbi ethembisayo njengebhlokhi yokwakha ye-anode yokunikela nge-ion. Kodwa kudinga ama-electrolyte abizayo nama-cathode uma sifuna ukuyivimbela ekuxhumaneni nezinye izakhi esitokisini, ngoba izibopho ezinjalo zibhubhisa ngokushesha uhlelo. Khonamanjalo, iGraphene Manufacturing Group ithi izokhipha amaseli enkinobho ye-aluminium-ion ngokuhamba kwesikhathi kulo nyaka noma ekuqaleni kuka-2022. Amasaka ezimoto kulindeleke ukuthi abe ngomumo ekuqaleni kuka-2024..

Amabhethri ezimoto asuselwe kumaseli e-aluminium-ion azoba lula hhayi ngenxa yokuminyana kwamandla aphezulu. Hhayi-ke, i-GMG ibika lokho Amaseli e-aluminium e-ionic awanazo izinkinga ngezinga lokushisa eliphezulu noma eliphansi, ngakho-ke kukhona ithuba lokuthi ngeke adinge ukupholiswa phansi noma ukushisisa kabusha.. Futhi, esikhathini esizayo, bazoba nesimo esifanayo futhi banikeze i-voltage efanayo namaseli we-lithium-ion wamanje, ngakho-ke angakwazi ukujwayela kalula kumaphakethe ebhethri akhona (umthombo).

Lokhu kungase kube nentshisekelo kuwe:
