Unyaka wezi-2022 unyaka okwaqala ngawo ukuqhuma kwesitoreji samandla saseShayina. Maphakathi no-Okthoba, iphrojekthi yokugcinwa kwamandla kagesi we-electrochemical enamandla angu-100 ngokubamba iqhaza kwe-Chinese Academy of Sciences izoxhunywa kugridi yase-Dalian ukuze isetshenziswe.Iphrojekthi kazwelonke yokuqala yaseChina engu-100MW yokugcina amandla e-electrochemical, kanye nesiteshi samandla esiphezulu sokulawula ibhethri eligeleza uketshezi esikhulu kunazo zonke emhlabeni esinamandla amakhulu nomthamo.
Iphakamisa nokuthi indawo yokugcina amandla yaseChina ingena ngokushesha.
Kodwa akugcini lapho.Isiteshi sikagesi esisezingeni lokuqala saseChina sesiqalisiwe eXinjiang, ngemuva kwalokho iphrojekthi yaseGuangdong yokubonisa indawo yokugcina amandla esezingeni lokuqala, iRulin Energy Storage Power Station yakwaHunan, iZhangjiakou Compressed Air Energy Storage Power Station kanye namaphrojekthi engeziwe angama-megawatt ayi-100 axhunyiwe. kugridi.
Uma ucabangela izwe lonke, kunezindawo zokugcina ezingaphezu kuka-65 100-megawatt ezihleliwe noma ezisebenzayo eShayina.Akulona ihaba elikhulu lelo.Ukutshalwa kwezimali kwakamuva kumaphrojekthi okugcina amandla e-China kungadlula i-1 trillion yuan ngo-2030, ngokusho kweNational Energy Administration.
Ezinyangeni zokuqala eziyi-10 zika-2022 kuphela, inani lokutshalwa kwezimali kweChina kumaphrojekthi okugcina amandla selidlule ama-yuan ayizigidi eziyizinkulungwane ezingama-600, lidlula zonke izimali ezitshaliwe zaseShayina zangaphambilini.Ngaphandle kwezwe, izimakethe zokugcina amandla ziklanywa eYurophu, e-United States, eJapan naseNingizimu Korea ngisho naseSaudi Arabia.Isikhathi sesakhiwo nesikali asikho ngaphansi kwesethu.
Sekushiwo lokho, i-China, kanye nomhlaba jikelele, ubhekene negagasi elikhulu lokwakhiwa kokugcinwa kwamandla.Abanye abangaphakathi embonini bathi: Ishumi leminyaka elidlule bekungumhlaba wamabhethri kagesi, okulandelayo umdlalo wokugcina amandla.
IHuawei, Tesla, Ningde Times, BYD nezinye iziqhwaga zamazwe aphesheya zijoyine lo mjaho.Kwethulwa umncintiswano oshube kakhulu kunomncintiswano wamabhethri kagesi.Uma ngabe kukhona oza phambili, kungenzeka kube yindoda eyazala iNingde Times yamanje.
Ngakho umbuzo uwukuthi: kungani ukuqhuma okungazelelwe kokugcinwa kwamandla, futhi yiziphi amazwe alwa ngazo?Ingabe i-Yongchao ingathola isisekelo?
Ukuqhuma kobuchwepheshe bokugcina amandla kuhlobene ngokuphelele namaShayina.Ubuchwepheshe bokuqala bokugcina amandla, okufanele baziwe kakhulu ngokuthi ubuchwepheshe bebhethri, basungulwa ngekhulu le-19 futhi kamuva bathuthukiswa baba yizinhlobonhlobo zemishini yokugcina amandla, kusukela ezishibhisi zamanzi kuya eziteshini zamandla e-photovoltaic kanye neziteshi zokugcina amandla kagesi ngamanzi.
Ukugcinwa kwamandla sekuphenduke ingqalasizinda.I-China ngo-2014 yaba ngeyokuqala ukuqamba ukugcinwa kwamandla njengenye yezindawo eziyisishiyagalolunye ezibalulekile zokuqanjwa kabusha, kodwa ikakhulukazi inkundla yobuchwepheshe bokugcina amandla ngo-2020 njengoba iChina kulo nyaka ifinyelele esicongweni sezinhloso zayo ezimbili zokungathathi hlangothi kwe-carbon, okuholele ekutheni uguquko.Amandla omhlaba namandla okugcina azoshintsha ngokufanele.
Amabhethri omthofu enza kuphela amaphesenti angu-4.5 yenani lonke ngenxa yokusebenza kwawo okungalungile, kuyilapho amabhethri e-sodium-ion kanye ne-vanadium ebhekwa ngabaningi njengokuthatha indawo yamabhethri e-lithium-ion okungenzeka kakhulu esikhathini esizayo.
I-sodium ions iphindwe izikhathi ezingaphezu kuka-400 ngaphezu kwe-lithium ion, ngakho-ke ishibhile kakhulu, futhi izinzile kumakhemikhali, ngakho awunakho ukusha nokuqhuma kwe-lithium.
Ngakho-ke, esimweni sezinsiza ezilinganiselwe ze-lithium-ion kanye nezintengo zebhethri ezikhulayo, amabhethri e-sodium-ion avele njengesizukulwane esilandelayo sobuchwepheshe obuningi obungapheli obungapheli.Kodwa iYongchao ihlose okungaphezu kobuchwepheshe bebhethri ye-sodium-ion.Siphishekela ukulinganiswa kwemboni yobuchwepheshe bebhethri ye-vanadium ion esikhathini sika-Ningde.
Izinsiza nokuphepha kwamabhethri e-vanadium ion aphakeme kunalawo e-lithium ion.Mayelana nezinsiza, iShayina iyizwe elicebe kakhulu emhlabeni e-vanadium, elinamaphesenti angama-42 ezinqolobane, eziningi zazo ezimbiwa kalula i-vanadium-titanium-magnetite.
Mayelana nokuphepha, i-vanadium flow battery electrolyte ene-dilute sulfuric acid solution equkethe i-vanadium ions, ngeke kwenzeke ukusha nokuqhuma, kanti i-electrolyte ewuketshezi, ingagcinwa ethangini lokugcina ngaphandle kwebhethri, ayithathi izinsiza ezingaphakathi kwebhethri, inqobo nje uma i-vanadium electrolyte yangaphandle, umthamo webhethri ungandiswa.
Ngenxa yalokho, ngokusekelwa nokukhuthazwa kwezinqubomgomo zikazwelonke, i-Yongchao Technology ithuthuka ngokushesha endleleni yocwaningo nokuthuthukiswa kobuchwepheshe bebhethri.
