Amandla elanga ahlala ethathwa njengomthombo wamandla ohambelana nokusingqongileyo. Ixabiso leepaneli zelanga kunye nee-injini zomoya zehle kakhulu kule minyaka ilishumi idlulileyo, nto leyo ebenza ukuba bakhuphisane ngakumbi namalahle kunye negesi yendalo. Kodwa uphuhliso kunye nolwalathiso lweebhetri ezithwala umbane ziya kuba nefuthe kuphuhliso lwale projekthi yeteknoloji.

Ngoku, into efanayo iyenzeka ngeebhetri, eziza kwenza ukuba izithuthi zombane zingabizi kwaye zivumele igridi ukuba igcine amandla angaphezulu ukubonelela xa kufuneka. Imfuno yeebhetri kushishino lwezothutho kuqikelelwa ukuba iza kukhula phantse kangangama-40 ngo-2040, ibeka uxinzelelo olwandayo kwikhonkco lokubonelela ngezinto ekrwada. Ukukhula kwenani lezithuthi zombane kwihlabathi liphela kuya kwandisa imfuno yombane. Ukubonelelwa kwezinto ezikrwada kwiibhetri ze-lithium kunokuba ngumba.

Ngokungafaniyo neepaneli zelanga, ukuveliswa kweeseli ezintsha zodwa akuyi kwanela ukuqinisekisa ukuhla kwexabiso eliqhubekayo ngaphandle kwesenzo sokujongana nokunqongophala kwezinto ezibalulekileyo. Iibhetri zeLithium ziqulethe izinyithi ezinqabileyo ezifana ne-cobalt, ixabiso layo liphindwe kabini kwiminyaka emibini edlulileyo, ukuphakamisa iindleko zemveliso yebhetri.

Iindleko zeebhetri ze-lithium-ion, ezilinganiswe nge-kilowatt-yure yombane owenziweyo, iye yawa ngama-75 ekhulwini kwiminyaka eyisibhozo edlulileyo. Kodwa ukunyuka kwamaxabiso kuya kubeka uxinzelelo olwandayo kwikhonkco lokubonelela ngezinto ezikrwada. Ngenxa yoko, ii-automakers ziye zajika kwiibhetri ze-lithium, ezisebenzisa iipesenti ezingama-75 ngaphantsi kwe-cobalt kuneteknoloji yangoku.

Iindaba ezilungileyo kukuba imboni yebhetri ayizami nje ukwandisa amandla okugcina amandla eebhetri ezinomlinganiselo ofanayo wezinto eziluhlaza, izama ukutshintshela kubonelelo oluninzi lwesinyithi.

Abatyali-mali bagalele imali kwi-startups ezinokuphuhlisa itekhnoloji entsha ethembisayo yebhetri, kunye nezixhobo ezijonge ukuphuhlisa iindawo zokugcina umbane omileyo zikwaqwalasela oko kubizwa ngokuba ziibhetri zokuhamba, ezisebenzisa izinto ezinokuphinda zisetyenziswe njenge-vanadium.

Emva kweminyaka engaphezu kwe-20 yophuhliso, i-vanadium flow battery ibe bubuchwepheshe bokugcina amandla obudala. Isalathiso saso sikwinqanaba le-MWh kwizikhululo zamandla ezinkulu zokugcina amandla ombane olutsha kunye neegridi zamandla. Iibhetri zeLithium zibalulekile kwiibhanki zamandla, zifana neepuni kunye nefosholo xa kuthelekiswa. azinakuthathelwa indawo enye kwenye. Ukhuphiswano olubalulekileyo lweebhetri ze-vanadium flow flow are large-scale energy storage such as hydraulic energy storage, compressed air energy storage, and flowing battery for other systems.

Iinkampani zombane ziya kuguqukela kwiibhetri ezihambayo, ezigcina amandla ombane kwizikhongozeli ezinkulu, ezizimela ngokwazo ezizaliswe lulwelo lwe-electrolyte, ethi emva koko impompelwe ebhetrini. Iibhetri ezinjalo zinokusebenzisa izinto eziluhlaza ezahlukeneyo, ezifana ne-metal vanadium esetyenziswa ngoku kwishishini lentsimbi.

Inzuzo yeebhetri ze-vanadium kukuba azilahlekelwa yintlawulo ngokukhawuleza njengeebhetri ze-lithium (inkqubo eyaziwa ngokuba yintlawulo yokubola). I-Vanadium ikwalula ukuyiphinda.

Xa kuthelekiswa neebhetri ze-lithium, iibhetri ze-vanadium redox ezihambayo zineenzuzo ezintathu ezibalulekileyo:

Okokuqala, lula. Inkqubo inokuba nkulu njengefriji yakho okanye ibe nkulu njengesikhululo esisezantsi kwindawo yakho. Kukho umbane owaneleyo wokunika amandla ikhaya lakho usuku ukuya enyakeni, ngoko ke unokuyila ngendlela ofuna ngayo.

2. Ubomi benkonzo ende. Unokufuna isiqingatha senkulungwane.

3. Ukhuseleko olulungileyo. Akukho xinzelelo ebusweni bexesha eliphezulu kunye nokugqithiswa, okuyi-taboo yeebhetri ze-lithium, kwaye akuyi kubakho umlilo kunye nokuqhuma konke.

I-China ilawula imveliso ye-vanadium kunye ne-akhawunti yesiqingatha sobonelelo lwehlabathi. Njengoko inani labavelisi bebhetri baseTshayina lisanda, kusenokwenzeka ukuba uninzi lweebhetri ziya kuveliswa eTshayina kumashumi eminyaka ezayo. NgokweBenchmark Mineral Intelligence, isiqingatha semveliso yebhetri yehlabathi inokuba kwilizwe lam ngo-2028.

Ukuba iibhetri ze-vanadium zisetyenziswa ngokubanzi kwizixhobo zokugcina iiseli zelanga, kunokwenzeka ukusebenzisa amandla ahlaziyekayo ukuhlawula iibhetri ze-lithium kwizithuthi zombane. Ikwavumela ukusetyenziswa kwezixhobo ezininzi ze-lithium kwi-automotive and electronic technology battery applications.
