Ukuvula amandla aVuselelekayo ngobuchwephesha bebhetri obukwinqanaba eliphezulu
Njengoko iinzame zehlabathi zokulwa nokutshintsha kwemozulu zisanda, impumelelo kwitekhnoloji yebhetri ibonakala njengeyona nto ibalulekileyo yokudibanisa amandla avuselelekayo kunye nokukhupha ikhabhoni. Ukususela kwizisombululo zokugcinwa kwegridi kwizithuthi zombane (EVs), iibhetri zesizukulwana esilandelayo zichaza ukugcinwa kwamandla ngelixa zijongene nemingeni ebalulekileyo kwiindleko, ukhuseleko kunye nefuthe lokusingqongileyo.
Ukuphumelela kwiChemistry yeBattery
Inkqubela phambili yakutsha nje kwezinye iikhemistri zebhetri zitshintsha imbonakalo yomhlaba:
- Iibhetri zeIron-Sodium: Ibhetri ye-iron-sodium ye-Inlyte Energy ibonisa ukusebenza kakuhle kwe-90% ukuya nokubuya kwaye igcina umthamo kwimijikelo engama-700, inikezela ngexabiso eliphantsi, ukugcinwa okuzinzileyo kwamandla elanga kunye nomoya.
- Iibhetri zeState-Solid: Ngokutshintshela i-electrolyte engamanzi anokutsha ngezinye iindlela eziqinileyo, ezi bhetri zongeza ukhuseleko kunye nokuxinana kwamandla. Ngelixa imiqobo ye-scalability isekhona, amandla abo kwii-EVs-ukunyusa uluhlu kunye nokunciphisa ingozi yomlilo-yinguqu.
- Iibhetri zeLithium-Sulfur (Li-S).: Ngoxinaniso lwamandla oluthiyori oludlula kakhulu i-lithium-ion, iinkqubo ze-Li-S zibonisa isithembiso sokuhamba ngenqwelomoya kunye nokugcinwa kwegridi. Izinto ezintsha kuyilo lwe-electrode kunye nokwakhiwa kwe-electrolyte kujongana nemingeni yembali efana ne-polysulfide shuttling.
Ukujongana nemingeni yoZinzo
Ngaphandle kwenkqubela phambili, iindleko zokusingqongileyo zemigodi ye-lithium zigxininisa iimfuno ezingxamisekileyo zezinye iindlela eziluhlaza:
- Ukukhutshwa kwe-lithium yemveli kudla imithombo yamanzi amaninzi (umzekelo, imisebenzi ye-Atacama brine yaseChile) kwaye ikhupha ~ iitoni ezili-15 ze-CO₂ ngetoni nganye ye-lithium.
- Abaphandi baseStanford kutshanje baye bavula indlela yokukhupha i-electrochemical, ukusika ukusetyenziswa kwamanzi kunye nokukhutshwa kwamanzi ngelixa bephucula ukusebenza kakuhle.
Ukunyuka kweNgcaciso yezinye iindlela
I-sodium kunye ne-potassium zifumana amandla njengeendawo ezizinzileyo:
- Iibhetri ze-sodium-ion ngoku ziphikisana ne-lithium-ion kubuninzi bamandla phantsi kobushushu obugqithisileyo, kunye ne-Physics Magazine igqamisa uphuhliso lwabo olukhawulezayo lwee-EV kunye nokugcinwa kwegridi.
- Iinkqubo ze-potassium-ion zibonelela ngeenzuzo zokuzinza, nangona ukuphuculwa koxinano lwamandla kuqhubeka.
Ukwandiswa kweBattery Lifecycle kuQoqosho lweSetyhula
Ngeebhetri ze-EV ezigcina i-70-80% yomthamo wokusetyenziswa emva kwemoto, ukusetyenziswa kwakhona kunye nokuphinda kusetyenziswe kwakhona kubalulekile:
- Izicelo zoBomi beSibini: Iibhetri ze-EV ezidla umhlala-phantsi zinika amandla indawo yokuhlala okanye ugcino lwamandla orhwebo, i-buffering intermittenncy ehlaziyekayo.
- Ukurisayikilisha iinguqulelo ezintsha: Iindlela eziphucukileyo ezifana ne-hydrometallurgical recovery ngoku ikhupha i-lithium, i-cobalt, kunye ne-nickel ngokufanelekileyo. Nangona kunjalo kuphela ~ 5% yeebhetri ze-lithium ziphinda zisetyenziswe namhlanje, ngaphantsi kwe-lead-acid's 99%.
- Abaqhubi bemigaqo-nkqubo abafana noxanduva lwe-EU oloNgezelelweyo loMvelisi (EPR) lubambe abavelisi bexanduva lolawulo lokuphela kobomi.
Umgaqo-nkqubo kunye neNtsebenziswano yokuBasa iNkqubela
Amanyathelo ehlabathi ayayikhawulezisa inguqu:
- UMthetho we-EU we-EU we-Critical Raw Materials Act uqinisekisa ukomelela kwekhonkco lonikezelo ngelixa ukhuthaza ukurisayikilishwa.
- Imithetho yeziseko zophuhliso yase-US ixhasa ngemali i-R&D yebhetri, ikhuthaza intsebenziswano phakathi kukarhulumente namashishini abucala.
- Uphando lwezoluleko olunqamlezayo, olufana nomsebenzi we-MIT wokuguga kwebhetri kunye ne-technology yokutsalwa yaseStanford, iibhulorho kwiziko lemfundo kunye neshishini.
Ngokubhekiselele kwi-Ecosystem yaMandla aZinzileyo
Indlela eya kwi-net-zero ifuna ngaphezulu kunophuculo olongezelelekileyo. Ngokubeka phambili iikhemistri ezisebenza kakuhle, izicwangciso zobomi besetyhula, kunye nentsebenziswano yamazwe ngamazwe, iibhetri ze-next-gen zinokunika amandla ikusasa elicocekileyo-ukulungelelanisa ukhuseleko lwamandla kunye nempilo yeplanethi. Njengoko uClare Grey wagxininisa kwintetho yakhe ye-MIT, "Ikamva lokufakelwa kombane lixhomekeke kwiibhetri ezingenamandla nje kuphela, kodwa ezizinzileyo kuzo zonke izigaba."
Eli nqaku ligxininisa ukubaluleka kwezinto ezimbini: ukukala izisombululo zogcino oluyilayo ngelixa ufaka uzinzo kwiyure nganye yewatt eveliswayo.
