Ngokuchasene nemvelaphi yenguqu yamandla ehlabathi kunye neenjongo "zekhabhoni ezimbini", itekhnoloji yebhetri, njengeyona nto ingundoqo yokugcina amandla, ifumene ingqwalasela ebalulekileyo. Kwiminyaka yakutshanje, iibhetri ze-sodium-ion (SIBs) ziye zavela kwiibhubhoratri ukuya kwimizi-mveliso, ibe sisisombululo esilindelweyo sokugcina amandla emva kweebhetri ze-lithium-ion.
Ulwazi oluSisiseko malunga neebhetri zeSodium-ion
Iibhetri zesodium luhlobo lwebhetri yesibini (etshajwayo) esebenzisa i-sodium ion (Na⁺) njengabathwali bentlawulo. Umgaqo wabo wokusebenza ufana neebhetri ze-lithium-ion: ngexesha lokuhlawula kunye nokukhupha, i-sodium ions shuttle phakathi kwe-cathode kunye ne-anode nge-electrolyte, eyenza ukugcinwa kwamandla kunye nokukhululwa.
·Izinto ezingundoqo: I-cathode ngokuqhelekileyo isebenzisa i-oxides enemibala, iikhompawundi ze-polyanionic, okanye i-analogues eluhlaza okwesibhakabhaka yasePrussian; i-anode ikakhulu yenziwe ngekhabhoni enzima okanye i-soft carbon; i-electrolyte sisisombululo setyuwa yesodium.
·Ukukhula kweTekhnoloji: Uphando lwaqala ngo-1980, kwaye ukuqhubela phambili kwamva nje kwizinto kunye neenkqubo kuphucule kakhulu ukuxinana kwamandla kunye nobomi bomjikelezo, okwenza urhwebo lube nokwenzeka.
Iibhetri zeSodium-ion vs.
Nangona iibhetri ze-sodium-ion zabelana ngesakhiwo esifanayo kunye neebhetri ze-lithium-ion, zihluke kakhulu kwiipropati eziphathekayo kunye neemeko zesicelo:
| Umlinganiselo wokuthelekisa | Iibhetri zeSodium-ion | Iibhetri zeLithium-ion |
| Ubutyebi obuninzi | Isodium ininzi (2.75% kuqweqwe loMhlaba) kwaye isasazwe ngokubanzi | ILithium inqabile (0.0065%) kwaye igxile ngokwejografi |
| Iindleko | Iindleko ezisezantsi zempahla ekrwada, ikhonkco lobonelelo oluzinzile | Ukuguquguquka kwexabiso eliphezulu le-lithium, i-cobalt, kunye nezinye izinto, ezixhomekeke kwizinto ezithunyelwa ngaphandle |
| Ukuxinana kwamandla | Phantsi (120-160 Wh/kg) | Phezulu (200-300 Wh/kg) |
| Ukusebenza kobushushu obuphantsi | Ugcino lwesakhono>80% ku -20℃ | Ukusebenza kakubi kumaqondo okushisa aphantsi, umthamo uyancipha ngokulula |
| Ukhuseleko | Ukuzinza okuphezulu kwe-thermal, ukumelana ngakumbi nokugqithisa / ukukhupha | Ifuna ulawulo olungqongqo lwemingcipheko yokubaleka eshushu |
Izinto eziluncedo ezingundoqo zeebhetri zesodium-ion:
1.Iindleko eziphantsi kunye noZinzo lweZibonelelo: I-sodium ifumaneka ngokubanzi emanzini olwandle kunye neemaminerali, ukunciphisa ukuthembela kwiintsimbi ezinqabileyo kunye nokunciphisa iindleko zexesha elide nge-30% -40%.
2. UKhuseleko oluPhakamileyo kunye nokuBulunga kokusiNgqongileyo: Ikhululekile kungcoliseko lwentsimbi enzima, ehambelana neenkqubo ezikhuselekileyo ze-electrolyte, kwaye ilungele ukugcinwa kwamandla amakhulu.
3. Ukuguquguquka koLudwe lobushushu olubanzi: Ukusebenza okugqwesileyo kwiindawo eziphantsi kweqondo lokushisa, ilungele imimandla ebandayo okanye iinkqubo zokugcina amandla ngaphandle.
Amathuba okusetyenziswa kweebhetri zeSodium-ion
Ngenkqubela phambili yetekhnoloji, iibhetri zesodium-ion zibonisa amandla amakhulu kwezi ndawo zilandelayo:
1. IiNkqubo zokuGcina amandla amakhulu (ESS):
Njengesisombululo esincedisayo samandla omoya namandla elanga, ixabiso eliphantsi leebhetri zesodium-ion kunye nobomi obude bunokunciphisa ngokufanelekileyo ixabiso elilinganayo lombane (LCOE) kunye nokuxhasa ukuchetywa kwegridi.
2. Izithuthi zoMbane ezinesantya esiphantsi kunye namavili amabini:
Kwiimeko ezineemfuno ezisezantsi zoxinano lwamandla (umzekelo, iibhayisekile zombane, izithuthi zolungiselelo), iibhetri zesodium-ion zinokuthatha indawo yeebhetri ze-lead-asidi, ezinika zombini izibonelelo zokusingqongileyo nezoqoqosho.
3. Ugcino lwaMandla kunye neSikhululo seSikhululo sokuGcina amandla:
Ukusebenza kwabo okubanzi komgangatho wobushushu kubenza bafanelekele iimfuno zamandla okugcinwa kuzo kwizicelo ezinobushushu obunobushushu obufana nezikhululo zonxibelelwano kunye namaziko edatha.
IiNdlela zoPhuhliso lwexesha elizayo
Uqikelelo lwemizi-mveliso luqikelela ukuba imakethi yehlabathi ye-sodium-ion ibhetri iya kudlula i-5 yeebhiliyoni zeedola ngo-2025 kwaye ifikelele kwi-10% -15% yemarike yebhetri ye-lithium-ion ngo-2030. Izalathiso zophuhliso lwexesha elizayo ziquka:
