Ungawathola Kanjani Amabhethri e-Lithium NMC ngo-2024

Ubuchwepheshe bebhethri buhambe ibanga elide futhi buye babona ukuthuthuka kwakamuva ekuminyana kwamandla kanye nokuminyana kwamandla. Kube nokukhuphuka okukhulu kwesidingo samabhethri e-lithium-ion (Li-ion), ikakhulukazi ikhemistri ye-lithium-nickel-manganese-cobalt (Li-NMC) kanye ne-lithium ferro-phosphate (LFP).

Kulesi sihloko, sizodlula umehluko phakathi kwebhethri le-NMC ne-LFP, sihlaziye amathuba emakethe ye-lithium-ion ye-NMC yomhlaba wonke, futhi sihlole izici ezibalulekile okufanele abathengisi bazicabangele lapho bekhetha. Amabhethri e-NMC ukwengeza ohlwini lwazo.

Umehluko phakathi kwamabhethri e-NMC ne-LFP

I-NMC ne-LFP ngamakhemikhali amabili e-lithium-ion asetshenziswa kakhulu. Nakuba zingase zibonakale zifana ebusweni ngoba zombili zine-lithium kuzo, kunomehluko obalulekile okufanele uhlolwe lapho uthatha isinqumo sokuthi uzotshala kuphi.

Njengoba amagama ephakamisa, amabhethri e-NMC asebenzisa inhlanganisela ye-cathode ye-nickel, manganese, ne-cobalt, kuyilapho amabhethri e-LFP esebenzisa ama-cathode asekelwe ku-iron. Ngakho, uhlobo lwebhethri ngalunye lunesethi yalo yezinzuzo eziyingqayizivele kanye nemikhawulo.

Umehluko oyinhloko yilokho Amabhethri e-NMC abe nokuminyana kwamandla okuphezulu kunamabhethri e-LFP, okusho ukuthi ayakwazi ukugcina amandla engeziwe kuphakheji elincane nelilula. Ngenxa yalokho, Amabhethri e-NMC zisetshenziswa ezinhlelweni ezahlukahlukene lapho ukubumbana nokukhanya kubekwa phambili, njengezimoto zikagesi (EVs) kanye nezinto zikagesi zabathengi.

Mayelana nokuphepha, nokho, amabhethri e-LFP anedumela lokunikeza ukuphepha okuphakeme nokuzinza okushisayo uma kuqhathaniswa namabhethri e-NMC. Nakuba ngokuvamile ephephile, amabhethri e-NMC awaqinile ngendlela eshisayo njengozakwabo be-LFP, kodwa lokhu kungavinjelwa amasistimu okulawula okushisayo afanele asiza ukuvimbela ukushisa ngokweqile nokuqinisekisa ukuphepha.

Ukubuka konke kwemakethe yebhethri ye-lithium-ion yomhlaba wonke ye-NMC

Ngokusho kombiko by Ucwaningo namaMakethe, imakethe yebhethri ye-lithium-ion yomhlaba wonke ye-NMC kulindeleke ukuthi ibone ukwanda okukhulu esikhathini sokubikezela sika-2022-2030. Izokhula ngenani elilindelekile lokukhula konyaka elihlanganisiwe (CAGR) lama-22.8% ukuze lifinyelele inani lemakethe lama-USD 14.9 billion ngo-2030.

Ukushayela lokhu kukhula kwemakethe kukhuphuka kwesidingo emhlabeni wonke sokufakwa kwebhethri le-NMC kumishini kagesi, ezimotweni zikagesi, namadivayisi ezokwelapha. Ukuminyana kwamandla okuphezulu, ukuminyana kwamandla, nokusebenza ngempumelelo kwezindleko zamabhethri e-NMC kuwenza afanelekele lezi zinhlelo zokusebenza. Ukwamukelwa okwandisiwe kwemithombo yamandla avuselelekayo kuphinde kwenza amabhethri e-NMC adumile ezinhlelweni zokugcina amandla.

Ngokuya ngokuhlukaniswa kwesifunda, i-Asia-Pacific injalo ibikezelwe ukuthi izoba yimakethe enkulu kunazo zonke amabhethri e-lithium-ion, njengoba isifunda sibona isidingo esikhulayo sama-EV, ukusekelwa okuqhubekayo kukahulumeni kwezixazululo zamandla avuselelekayo, nokukhiqizwa okwandisiwe kwamabhethri e-Li-ion.

7 izici okufanele zicatshangelwe lapho ukhetha ibhethri le-NMC

Manje njengoba sesinombono wokuthi ayini amabhethri e-NMC namathemba awo emakethe eminyakeni ezayo, ake sihlole ukuthi yini okudingeka uyicabangele lapho ukhetha lolu hlobo lwebhethri ngaphezu kwamanye atholakalayo emakethe.

1. Amandla

Njengoba umsebenzi oyinhloko wamabhethri uwukugcina amandla amakhemikhali futhi uwaguqule abe amandla kagesi, ukwazi umthamo webhethri kubaluleke kakhulu enqubweni yokukhetha.

The umthamo olinganiselwe yebhethri le-NMC isho inani elishiwo likagesi ibhethri elikwazi ukulikhulula ngaphansi kwezimo ezithile zokuchithwa. I umthamo wangempela ibhekisela enanini langempela likagesi ibhethri eliwukhiphayo ngaphansi kwezimo ezithile zokuchithwa. Izinto ezifana nezinga lokukhipha kanye nezinga lokushisa kuzothinta lokhu.

Umthamo webhethri ulinganiswa ngamahora we-ampere (Ah). Kubalulekile kubathengi ukuthi baqaphele umthamo webhethri ukuze baqinisekise ukuphakelwa kwamandla okusebenzayo nokuthembekile ezidingweni zokusetshenziswa kwekhasimende eliqondiwe.

2. Amandla

Ngale komthamo, kubalulekile futhi ukuhlola amandla kagesi ebhethri le-NMC. Ukukhetha ibhethri elingenawo amandla kagesi alungile kuyingozi yokulimaza amadivaysi noma awenze angasebenzi kahle.

Amabhethri e-Li-ion NMC ngokuvamile babe nobubanzi be-voltage okuzisholo ukuthi buphakathi 3.5 kanye 3.7 volts ngeseli. Ngakho-ke, abathengi kufanele baqinisekise ukuthi i-voltage yamabhethri ihambisana namadivayisi amabhethri ahloselwe wona noma adayiswa ukuze abe namandla.

3. Ubukhulu nesisindo

Njengoba kushiwo ngaphambili, amabhethri e-NMC anomthamo omkhulu wamandla uma kuqhathaniswa namabhethri e-LFP, ngaleyo ndlela avumela amadizayini aminyene futhi angasindi. Lokhu kufanele kucatshangelwe uma kunqunywa ukuthi iliphi ibhethri elikhethwayo, njengoba usayizi nesisindo samabhethri kuthinta ukuphatheka kwamadivayisi asetshenziswa kuwo.

Ukukhetha amabhethri aminyene kakhulu futhi kulula ukuwaphatha kuthinta kakhulu ukusebenziseka kwamadivayisi ahlukene.

4. Inani eliphezulu lokushaja kanye nokukhishwa kwamandla

Ubukhulu bokushaja nokukhipha amandla ebhethri le-NMC kuthinta isikhathi esisithathayo ukushaja ibhethri. Ukuqinisekisa ukuthi ibhethri isebenza kahle ngokulayishwa kwedivayisi, kubalulekile ukukhetha amabhethri anobukhulu obufanele bokushajwa kanye namandla okuphuma.

Ukungenzi lokhu kungaholela ezikhathini zokushaja kancane kanye nomonakalo kumadivayisi asetshenziswa amabhethri.

5. Impilo yomjikelezo weseli

Enye into ebalulekile okufanele icatshangelwe lapho ukhetha ibhethri le-NMC impilo yomjikelezo weseli. Impilo yomjikelezo wamaseli ebhethri ibhekisela enanini lokushaja nokukhipha imijikelezo ibhethri elikwazi ukuyiqeda ngaphambi kokuthi lilahlekelwe ukusebenza kwalo.

Amabhethri anomjikelezo wempilo ende ayakwazi ukuletha amandla esikhathini eside, okusho ukuthi kuzoba nokushintshwa okumbalwa okudingekayo. Ngakho-ke, kubalulekile ukucabangela lokhu njengoba kuthinta ukusetshenziswa kwesikhathi eside.

I-6. Ukuphepha

Uma kukhulunywa ngamabhethri e-lithium, ukuphepha kufanele kube yinto ehamba phambili. Ngenxa yokuthi zingase zethule ingozi yomlilo noma ukuqhuma lapho zihluleka ukusebenza ngokuphepha noma zilimale, kubalulekile ukukhetha amabhethri ahlolwe kanzima futhi athobela izindinganiso zokuphepha.

Nakuba amabhethri e-LFP ebhekwa njengephephile ngenxa yokuzinza kwawo okushisayo, amabhethri e-NMC anezinhlelo ezifanele zokulawula ukushisa angavimbela izingozi zokuphepha zamazinga okushisa aphezulu kanye nokushisa ngokweqile ukuze kuqinisekiswe ukusebenza okuphephile.

7. Umthelela wendawo

Kuyaphawuleka ukuthi ngokungafani namabhethri e-LFP asebenzisa izinto zokusetshenziswa ezingenabo ubuthi futhi ezitholakala kalula, amabhethri e-NMC, ikakhulukazi lawo ane-cobalt, abeka izinselele ezithile zemvelo nezimiso zokuziphatha ngenxa yemikhuba engasimeme ezimayini ze-cobalt.

Sekushiwo lokho, okwamanje ucwaningo luyenziwa mayelana nokuthuthukiswa kwezinhlobonhlobo zamabhethri e-NMC angenayo i-cobalt, okuzosiza ukubhekana nalokhu kukhathazeka eminyakeni ezayo.

Engeza amabhethri e-NMC alungile ohlwini lwakho lwamagama

Amabhethri e-NMC alapha ukuze ahlale, futhi njengoba ukuqagela kwemakethe kubonisa, azozuza ingxenye yemakethe eyengeziwe njengengxenye yebhethri ye-lithium-ion. Ukufaneleka kwazo kwamandla aphezulu kanye nokuminyana kwamandla kuzenza zibe inketho ekhethwayo yokusetshenziswa ezimotweni zikagesi kanye nezinto zikagesi zabathengi.

Ngakho-ke uma ubheke ukuthola amabhethri e-NMC ozowangeza ohlwini lwakho lwamagama, thatha isikhathi sokucabangela umthamo, amandla kagesi, ukushajwa okuphezulu kanye nokukhipha amandla, impilo yomjikelezo weseli, nokuphepha kwamabhethri. Ukuze uthole uhla olubanzi lwe Amamodeli ebhethri e-NMC ongakhetha kukho, vakashela Chovm.com futhi uhlole uhla lwemibhalo olubanzi lwabahlinzeki kanye nezinketho zomkhiqizo.
