Ukuvula Amandla Avuselelekayo Ngezobuchwepheshe Bebhethri Ezithuthukisiwe
Njengoba imizamo yomhlaba wonke yokulwa nokushintsha kwesimo sezulu iqina, intuthuko kwezobuchwepheshe bebhethri iyavela njengezinto ezibalulekile ezibangela ukuhlanganiswa kwamandla avuselelekayo kanye nokususwa kwekhabhoni. Kusukela kuzixazululo zokugcina igridi kuya ezimotweni zikagesi (ama-EV), amabhethri esizukulwane esilandelayo achaza kabusha ukusimama kwamandla ngenkathi ebhekana nezinselele ezibalulekile zezindleko, ukuphepha, kanye nomthelela wemvelo.
Ukuphumelela Kwe-Chemistry Yebhethri
Intuthuko yakamuva kwezamakhemikhali ebhethri ehlukile ishintsha isimo:
- Amabhethri E-Iron-SodiumIbhethri le-iron-sodium le-Inlyte Energy libonisa ukusebenza kahle okungu-90% kokuhamba nokubuya futhi ligcina amandla ngaphezu kwemijikelezo engu-700, linikeza isitoreji esingabizi futhi esihlala isikhathi eside samandla elanga nawomoya.
- Amabhethri Esimo Esiqinile: Ngokushintsha ama-electrolyte ashisayo ngezinye izindlela eziqinile, lawa mabhethri athuthukisa ukuphepha kanye nobuningi bamandla. Nakuba izithiyo zokukhula zisekhona, amandla awo kuma-EV—ukukhulisa ububanzi nokunciphisa izingozi zomlilo—ayashintsha.
- Amabhethri e-Lithium-Sulfur (Li-S): Njengoba ubuningi bamandla obungokwemfundiso budlula kakhulu i-lithium-ion, izinhlelo ze-Li-S zibonisa isithembiso sokugcina izindiza kanye negridi. Ukuqamba okusha ekwakhiweni kwe-electrode kanye nokwakheka kwe-electrolyte kuxazulula izinselele zomlando ezifana nokuthutha kwe-polysulfide.
Ukubhekana Nezinselele Zokuzinza
Naphezu kwentuthuko, izindleko zemvelo zokumbiwa kwe-lithium zigcizelela izidingo eziphuthumayo zezinye izindlela eziluhlaza:
- Ukukhishwa kwe-lithium yendabuko kudla imithombo yamanzi eminingi (isb., imisebenzi ye-Atacama brine yaseChile) futhi kukhipha amathani angu-15 e-CO₂ ngethani le-lithium.
- Abacwaningi baseStanford basanda kuqala indlela yokukhipha amanzi nge-electrochemical, banciphisa ukusetshenziswa kwamanzi kanye nokukhishwa kwawo ngenkathi bethuthukisa ukusebenza kahle.
Ukwanda Kwezindlela Eziningi Zokubhekana Nezinkinga
I-Sodium ne-potassium ziya ngokuya zithandwa njengezinto ezithatha indawo ezinzile:
- Amabhethri e-sodium-ion manje ancintisana ne-lithium-ion ekubunjweni kwamandla ngaphansi kwamazinga okushisa aphezulu, kanti i-Physics Magazine igqamisa ukuthuthukiswa kwawo okusheshayo kwama-EV kanye nesitoreji segridi.
- Izinhlelo ze-potassium-ion zinikeza izinzuzo zokuzinza, yize ukuthuthukiswa kobuningi bamandla kuqhubeka.
Ukwandisa Umjikelezo Wempilo Yebhethri Ukuze Umnotho Ojikelezayo Ube Yindilinga
Njengoba amabhethri e-EV egcina umthamo ongu-70–80% wokusetshenziswa ngemva kwemoto, ukusetshenziswa kabusha kanye nokusetshenziswa kabusha kubalulekile:
- Izicelo Zokuphila Kwesibili: Amabhethri e-EV asethathe umhlalaphansi anika amandla isitoreji samandla sendawo yokuhlala noma sezentengiselwano, okuvimbela ukuphelelwa yisikhathi okuvuselelwayo.
- Ukuvuselela Izinto EzintshaIzindlela ezithuthukisiwe ezifana nokuvuselelwa kwe-hydrometallurgical manje zikhipha i-lithium, i-cobalt, kanye ne-nickel ngempumelelo. Kodwa-ke amabhethri e-lithium angu-5% kuphela aphinde asetshenziswe namuhla, angaphansi kakhulu kwesilinganiso se-lead-acid esingu-99%.
- Abashayeli bezinqubomgomo njengomyalelo we-Extended Producer Responsibility (EPR) we-EU babamba abakhiqizi icala ngokuphathwa kokuphela kwempilo.
Inqubomgomo Nokubambisana Okubangela Intuthuko
Imizamo yomhlaba wonke isheshisa ushintsho:
- UMthetho Wezinto Ezisetshenziswayo Ezibalulekile we-EU uqinisekisa ukuqina kochungechunge lokuhlinzeka ngenkathi ukhuthaza ukuvuselelwa kabusha.
- Imithetho yengqalasizinda yase-US ixhasa i-R&D ebhubhisayo, ikhuthaza ukubambisana komphakathi nezinkampani ezizimele.
- Ucwaningo oluhlanganisa imikhakha eyahlukene, njengomsebenzi we-MIT wokuguga kwebhethri kanye nobuchwepheshe bokukhipha ibhethri eStanford, luhlanganisa izikhungo zemfundo ephakeme kanye nezimboni.
Ukuya ohlelweni lwe-Ecosystem oluqhubekayo lwamandla
Indlela eya ku-net-zero idinga okungaphezu kokuthuthukiswa okuqhubekayo. Ngokubeka phambili amakhemikhali asebenzisa kahle izinsiza, amasu omjikelezo wokuphila ojikelezayo, kanye nokubambisana kwamazwe ngamazwe, amabhethri esizukulwane esilandelayo anganika amandla ikusasa elihlanzekile—ukulinganisela ukuphepha kwamandla nempilo yeplanethi. Njengoba uClare Grey egcizelele enkulumweni yakhe ye-MIT, "Ikusasa lokufakelwa kukagesi lincike kumabhethri angenamandla nje kuphela, kodwa azinzile kuzo zonke izigaba."
Lesi sihloko sigcizelela ukubaluleka okubili: ukwandisa izixazululo zokugcina ezintsha ngenkathi kufaka ukusimama kuyo yonke i-watt-hour ekhiqizwayo.
