Yintoni eNgcono, iibhetri zeLithium-Ion okanye iLithium Iron Phosphate?
Ukugcina okumileyo kunye nothutho lwentengiso, i-LFP iphumelela kwiindleko zizonke zobunini malunga ne-80% yeeprojekthi esizibonayo. I-NMC isenengqiqo malunga -nosetyenziso olunyanzelweyo kunye nokubandayo{3}} kokusasazwa kwemozulu ngaphandle kohlahlo lwabiwo-mali lolawulo lobushushu. Nantso ke impendulo emfutshane.
Impendulo ende ibandakanya umjikelo wakho womsebenzi othile, imiqobo yesiza sakho, kwaye ngokunyaniseka, yintoni iCFO yakho ezimisele ukuyisayina ngaphambili ngokuchasene neendleko zomjikelo wobomi. Ukuba uthelekisa iikowuti zababoneleli ngoku okanye wakha i-spec ye-RFP, yonke le nto iquka izinto esizifundileyo ekusebenzeni.
Ukuthathwa kwemakethi ye-LFP kwenzeke ngokukhawuleza kunokuba uninzi lwabahlalutyi bebeqikelele. 49% ye-EV yeebhetri zehlabathi jikelele ngo-2024, kufutshane{2}}nolawulo lulonke kugcino lwegridi. UTesla utshintshe iMegapack kwiiseli ze-LFP zeCATL kunye newaranti eyandisiweyo ukuya kwiminyaka eyi-15. Iprojekthi ye-BYD ye-12.5 GWh kunye neNkampani yoMbane yaseSaudi ihambe nge-LFP. I-CATL ibango zero zero zezehlo ze-thermal kwi-256 GWh esetyenzisiweyo. Ishishini livote ngezigqibo zalo zokuthenga.
Kodwa amanqaku othelekiso lwekhemistri ajikelezayo ayaphoswa yintoni eneneni eqhuba ezi zigqibo kwinqanaba leprojekthi. Amanani oxinaniso lwamandla awakuxeleli ukuba ufakelo lwakho luza kungena kwindawo eyabelweyo. Iinkcazo zobomi bomjikelo azibaleli iipateni zokuthotywa oza kuzibona phantsi kweemeko zakho zokusebenza. Amaqondo obushushu apapashiweyo okubalekayo awatoliki ngokuthe ngqo kwinto eya kufunwa ngumcimi-mlilo wakho.
Okwenyani-Imeko yeHlabathi
Besinomthengi we-telecom kulo nyaka uphelileyo i-spec NMC yofakelo lwe-backup kuba amanani oxinano lwamandla omthengisi akhangeleka ngcono ephepheni. Utyelelo lwesiza luveze ukuba baya kudinga ukongeza umthamo we-HVAC ukuphatha umthwalo oshushu. Ukuphuculwa koxinzelelo lomlilo kutyhalele umva umva kwiinyanga ezintathu. Itotali yeendleko ezifakiweyo zeza ngama-22% ngaphezu kwe-LFP eyenye ebebeyikhabile ekuqaleni. Iiseli ze-NMC ngokwazo bezitshiphu ngekWh nganye. Yonke into eyayibangqongileyo yayingekho.
Le pateni iyaphinda. Isigqibo sekhemistri yebhetri singena kwiindleko ze-BOS, ixesha lokuvumela ixesha, iimfuno ze-inshurensi, kunye nezivumelwano zokulondolozwa. Amaqela okuthenga agxininise kumxinwa kwiseli{2}}imilinganiselo yenqanaba ephosa le nkqubo{3}}iziphumo zomgangatho.
Kubomi bomjikelo, amanani ababoneleli bamanani acaphula afanele ukuphononongwa. "Imijikelo ye-5,000 ukuya kwi-80% umthamo" ivakala ngokuthe ngqo de umbe kwiimeko zovavanyo. Yeyiphi inqanaba C-? Bubuphi ubunzulu bokukhutshwa? Loluphi uluhlu lobushushu? Iseli evavanywe kwi-0.5C kunye ne-25℃kwilebhu yenza ngokuhluke kakhulu kwibhayisikili enye kwi-1C kwisitya sokuthumela ePhoenix.
Okwenyani-idata yezithuthi zehlabathi iyaqala ukubonakala. Inyathelo le-Electric School Bus Initiative lilandele umkhondo we-847 LFP{3}}iibhasi ezixhotyiswe nge-7.2% kunye nokuthotywa komthamo kwiminyaka emihlanu yokusebenza. Oko kungcono kuneengcinga ezininzi zewaranti. Izithuthi ze-NMC zibonisa umahluko ongakumbi{7}}ezinye zibambe kakuhle, ezinye zibetha imida yewaranti ngaphambi kwexesha elilindelekileyo. Umgangatho weseli kunye nomgangatho wolawulo lwe-thermal ubaluleke ngaphezu kweleyibhile yekhemistri kwi-spec sheet.
Uhlalutyo lwe-DOE luka-2020 lokugcinwa kwegridi luqikelele ukuba i-LFP ihlala malunga ne-67% ubude kune-NMC phantsi kweemeko ezifanayo zokukhwela ibhayisekile. Ipapashwe kwi-energy.gov. Indlela yokusebenza ithande iprothokholi zovavanyo olusemgangathweni, ngoko ke{5}}umahluko wehlabathi uya kwahluka, kodwa isiphelo sesalathiso sibambe uninzi lweemeko zokusebenza esizenzileyo.
Ukusebenza kwemozulu ebandayo kulapho i-LFP isilela ngokunyanisekileyo, kwaye ayipheleli ekunciphiseni umthamo.
Ukutshaja i-LFP ngaphantsi kwe-0℃kubangela i-lithium plating kwi-anode. Ayincitshiswanga ukusebenza{2}}umonakalo osisigxina oqokelelekayo ngesiganeko ngasinye sentlawulo ebandayo. Iseli ibonakala ilungile. I-BMS ayinakuphawula nantoni na. Kodwa uthoba isidima sepakethi ngalo lonke ixesha.
Iiprothokholi zokutshaja kwishishini ziphendula ngokucutha amaxabiso entlawulo kumaqondo obushushu aphantsi. Kwi -10℃, izinga elivumelekileyo lehla ukuya malunga ne-0.02C. Amashumi amahlanu kunye neeyure zentlawulo epheleleyo ngelo xesha. Ukungasebenzi kakuhle ngaphandle kokufudumeza okusebenzayo.
Sicaphule iiprojekthi kuMbindi-ntshona ophezulu apho ulawulo lobushushu bongeze i-12-18% kwiindleko zesistim. I-insulated enclosures, izinto zokufudumeza, izilawuli. Kusafakwe ipensile ngokuchasene ne-NMC kwi-TCO yeminyaka eli-10, kodwa uNyaka woku-1 ubeyinkunzi eyinkunzi kwaye ifuna ukusayinwa kwesigqeba esingaphaya kohlahlo lwabiwo-mali lweprojekthi.
Ukuba ufakelo lwakho lujongene-neqondo lobushushu eliphantsi lokukhenkceza kwaye uhlahlo lwabiwo-mali lwakho lokufudumeza luthintelekile, i-NMC inokuba lucingo oluchanekileyo ngaphandle kweendleko eziphezulu zomjikelo wobomi. Sithethe nabathengi kwi-NMC kanye ngesi sizathu. Ayiyiyo yonke iprojekthi ekufuneka ibe yi-LFP.
Kumaxabiso, iBloombergNEF 2024-uphando luka-2025 lubonisa iindleko zomgangatho wepakethi malunga ne-$81/kWh ye-LFP xa ithelekiswa ne-$128/kWh ye-NMC. Kodwa amaxabiso epakethi awayibambi into oza kuyihlawula ngokwenene.
Amaxabiso aseTshayina e-LFP ehle ngaphantsi kwe-$50/kWh phakathi- ngo-2024. Ezinye iintengiselwano zendawo kuthiwa zivaliwe phantsi kweedola ezingama-40/kWh. Imeko yonikezelo ngokugqithisileyo yeyokwenyani-CATL kunye ne-BYD engxamisekileyo phambi kwemfuno, kwaye abavelisi abancinci babhangisa uluhlu lwempahla. Ukuba uthenga umthamo kwaye iqela lakho lokuthenga liyayazi indlela yokuthethathethana, imiyinge epapashiweyo yisilingi, hayi imigangatho.
Icala elisecaleni: iiseli ezitshiphu ezisuka kubaboneleli abanxungupheleyo ngamanye amaxesha zithetha umahluko womgangatho. Sizibonile iibhetshi ezinomthamo usasazeke ngokubanzi kune-spec. Imiba yokulinganisa i-BMS. Amaxwebhu angahambelaniyo noko kukwikhreyithi. Iiseli ezingama-45/kWh ezifuna i-15% ngaphezulu yabasebenzi be-QC kwaye zenze amabango ewaranti aziyigcini imali.
Ubudlelwane obusekiweyo kunye -nomthengisi omnye (CATL, BYD, EVE, CALB ye-LFP; i-Samsung SDI, i-LG Energy Solution, i-SK On ye-NMC) rhweba enye inzuzo yeendleko zokuthembeka konikezelo. Ukunyamezela kwakho umngcipheko kunye nomthamo wokuthenga umisela indawo omawufike kuyo kuloo ndawo.
