Ugcino lwe-hydro emponthiweyo luxabisa kancinci kwiimfuno zexesha elide{13} kodwa lufuna indawo ethile kwaye kuthatha iminyaka ukuphuhla. Iibhetri eziqukuqelayo zinika iminyaka engama-25-iminyaka engama-30 yobomi ngaphandle kokuthotywa, izenza zibenomtsalane kusetyenziso olufuna ukukhwela ibhayisekile yonke imihla kumashumi eminyaka, nangona ixabiso eliphezulu langaphambili licotha ukwamkelwa. Umoya oxiniweyo kunye nogcino lwe-thermal luhambelana nezicelo ezithile kodwa akukho nto i-lithium-ion's versatility. Kwiinkonzo zegridi zeeyure ze-2-4, i-lithium-ion okwangoku ayinayo enye indlela yokukhuphisana ngeendleko kwinqanaba.
Yintoni ebangela imililo yebhetri ye-lithium - kwaye yenzeke kangaphi?
I-Thermal runaway iqala xa iiseli zitshisa ngaphaya komda wokunyamezela{0}}ngokwesiqhelo ukusuka kwiisekethi ezimfutshane ezibangelwa kukutshaja, ukonakala koomatshini, okanye iziphene zokwenziwa. Amaqondo obushushu angaphakathi ajikela phezulu ngokusabela kwe-exothermic, ukufunxa ii-electrolyte ezinokutsha ezinokuvutha. Amazinga okusilela anamhlanje ehle aye malunga nesehlo esinye nge-10 -i-15 GWh esasazwe ukusukela ngo-2024, ezantsi ukusuka ku-1 nge-4-5 GWh ngo-2020. Ikhemistri ye-LFP ibonisa iiprofayili ezingcono kakhulu zokhuseleko kuneendlela ezizezinye ezisekwe nickel. Uthintelo lugxile ekuveliseni umgangatho, iinkqubo zolawulo lobushushu, ukujongwa kwesilumkiso kwangethuba, kunye neempawu zoyilo eziqulathe okanye ezicinezela imililo ngaphambi kokusasazwa.
Ngaba iinkqubo zokuhlala zelanga zisebenza ngokufanelekileyo ngaphandle kokugcinwa kwebhetri?
Ewe, kodwa ngokusikelwa umda. Igridi-ebotshelelwe kwisolar ngaphandle kweebhetri ixhomekeke kwinethi yemigaqo-nkqubo yemitha ebolekisa ngokugqithisileyo ekusetyenzisweni kwangokuhlwa. Apho kukho ukulinganisa okufanelekileyo kwesambuku kukho, iibhetri zongeza iindleko ngaphandle kwenzuzo enkulu yemali ngaphandle kokuba amandla okugcina amanzi athethelela inkcitho. Nangona kunjalo, iCarlifonia kunye neminye imimandla yanciphisa imbuyekezo yokuthumela ngaphandle emva kowama-2024, isenza ukuba iibhetri zibaluleke kakhulu kwiinkqubo zelanga zoqoqosho. Vala{6}}igridi okanye iimeko zegridi ezingathembekanga zifuna iibhetri. Olona khetho lufanelekileyo luxhomekeke kwimigaqo-nkqubo yasekhaya, amaxabiso ombane, kunye nexabiso elibekwe kumandla okuzimela kunye nokukwazi ukulondoloza ngexesha lokucima.
Ingcamango yokugqibela
Iinkqubo zokugcina amandla ebhetri ye-Lithium-ioni zihambile ukusuka kwindima exhasayo ukuya kwintsika esembindini kutshintsho lweziseko zamandla. Ukwehliswa kweendleko zethekhinoloji ngama-90% ukusukela ngo-2010 kwenze ukuba usasazwe lube luncedo kwimilinganiselo ebikade ithathwa njengento engenakwenzeka ngokwezoqoqosho. Njengoko isizukulwana esinokuhlaziywa siqhubeka sisanda kwihlabathi jikelele, inkqubo yokugcina amandla i-lithium ion ibhetri yetekhnoloji ibonelela ngokuguquguquka okwenza imithombo ephakathi ethembekileyo ibe yezinye iindlela ezithembekileyo.
Icandelo lijongene nemingeni esemthethweni malunga nokhuseleko, amakhonkco obonelelo, kunye nokuthotywa komsebenzi. Nangona kunjalo iingongoma ezikhokelela ekucuthweni kweendleko eziqhubekayo, ukuphuculwa kwezakhiwo zokhuseleko, kunye nezinye iikhemistri ezilungisa imida yangoku. Imibutho kunye nabaqulunqi bomgaqo-nkqubo abaphatha inkqubo yokugcina amandla ebhetri ye-lithium ion njengento yokuzikhethela baya kuzifumana bekwingxaki yokhuphiswano njengoko igridi yamandla ihlengahlengisa ngokusisiseko ukujikeleza ukuveliswa okunokuvuselelwa.
