Iphrojekthi ye-Alise: Amaseli ethu e-lithium-sulphur afinyelele ku-0,325 kWh / kg, siya ku-0,5 kWh / kg

I-Alise Project iphrojekthi yocwaningo exhaswe yi-European Union, ebandakanya izinkampani nezinhlangano eziyi-16 ezivela emazweni ayi-5. Ososayensi bamane bazishaya isifuba ngokuthi badale iseli ye-prototype Li-S (lithium-sulphur) enamandla angu-0,325 kWh/kg. Amaseli e-lithium-ion angcono kakhulu asetshenziswayo njengamanje afinyelela ku-0,3 kWh/kg.

Uhlu lokuqukethwe

Ukuminyana okuphezulu = ububanzi bokushajwa kwebhethri
- U-Li-S emotweni: ishibhile, ngokushesha, ngokuqhubekayo. Kodwa hhayi manje

Ukuminyana kwamandla okuphezulu kweseli kusho ukuthi lingagcina amandla engeziwe. Amandla engeziwe ngeyunithi ngayinye yesisindo noma amabanga aphezulu ezimoto zikagesi (ngenkathi ugcina usayizi webhethri wamanje), noma ngenye indlela ububanzi bamanje anamabhethri amancane nalula... Noma ngabe iyiphi indlela, isimo sihlezi singumnqobi kithi.

Amaseli e-lithium-sulphur ayinto ewusizo kakhulu yokufunda uma kukhulunywa ngokuminyana kwamandla ngeyunithi ngayinye yesisindo. I-lithium nesibabule yizici ezilula, ngakho-ke i-elementi ngokwayo ayinzima. Iphrojekthi ye-Alise ikwazile ukuzuza u-0,325 kWh/kg, cishe ngamaphesenti angu-11 ngaphezu kwalokho okufunwa i-CATL yaseChina kumaseli ayo e-lithium-ion asezingeni eliphezulu:

Omunye wabahlanganyeli be-Alise Project, i-Oxis Energy, ngaphambili wayethembise ukuminyana kwe-0,425 kWh / kg, kodwa kuphrojekthi ye-EU, ososayensi banquma ukwehlisa ukuminyana ukuze, phakathi kwezinye izinto, bazuze: amandla aphezulu okushaja. Nokho, ekugcineni bafuna ukushintshela ku-0,5 kWh/kg (umthombo).

Ibhethri lisekelwe kumamojuli agcwaliswe ngamaseli e-Li-S (c) Alise Project.

U-Li-S emotweni: ishibhile, ngokushesha, ngokuqhubekayo. Kodwa hhayi manje

Amaseli e-lithium nesibabule abukeka ethembisa, kodwa isasasa liyaphela okwamanje. Bakukhumbuza ukuthi kusekude phambili. Ngokwesibonelo Amabhethri e-Li-S okwamanje amelana cishe nemijikelezo yokushaja eyi-100.kuyilapho imijikelezo engu-800-1 ithathwa njengencane enengqondo namuhla, futhi sekuvele kunezibonelo ezithembisa imijikelezo yokushaja engu-000-3:

Izinga lokushisa nalo liyinkinga: ngaphezu kuka-40 degrees Celsius, amaseli e-Li-S abola ngokushesha... Abacwaningi bangathanda ukuphakamisa lo mngcele okungenani ube amadigri angu-70, izinga lokushisa elenzeka ngokushaja okusheshayo.

Kodwa-ke, kukhona okumele kulwelwe, ngoba lolu hlobo lweseli aludingi i-cobalt ebizayo, okunzima ukuyithola, kodwa kunalokho i-lithium eshibhile nesibabule esivame ukutholakala. Ikakhulukazi njengoba ukuminyana kwamandla etiyetha kusibabule kufika ku-2,6 kWh/kg - cishe izikhathi eziyishumi kunamaseli e-lithium-ion angcono kakhulu athulwe namuhla.
