Kwihlabathi eliguquka ngokukhawuleza lokugcina amandla, iintlobo ezimbini zeebhetri ziye zaba ziindaba eziphambili:Iibhetri zeSodium-ion (iiSIB)kwayeIibhetri zeLithium-iron-phosphate (iibhetri zeLFP). Zombini iteknoloji yebhetri yesodiyam kunye neteknoloji yebhetri yelithium ziiteknoloji ezithembisayo, kodwa zineempawu ezahlukeneyo ezenza zilungele ukusetyenziswa ezahlukeneyo. Kweli nqaku, siza kuhlola ukuba zeziphi iibhetri zesodiyam-ion kunye ne-lithium-iron-phosphate, size emva koko sithelekise umahluko wazo ngokusekelwe kwiziphumo zophando lwakutshanje.
Zithini iiBhetri zeSodium-ion (iiSIB)?
Iibhetri zeSodium-ion (iiSIB)luhlobo lwebhetri etshajwayo esebenzisa ii-ion ze-sodium (Na+) njengezithwali zokutshaja. I-sodium ininzi kwaye ayibizi kakhulu, nto leyo eyenza ii-SIB zibe yiteknoloji entsha yebhetri yokutshintsha i-lithium.
Ii-SIB zihlala zisebenzisa i-hard carbon njengezinto ze-anode, nto leyo eyahlukileyo kwi-graphite esetyenziswa kakhulu kwi-LIBs. Izinto ze-cathode zingahluka, kodwa zihlala zenzelwe ukwamkela ubungakanani obukhulu bee-sodium ions xa kuthelekiswa nee-lithium ions.
Zithini iibhetri ze-LFP (ibhetri yeLithium-iron-phosphate)?
Iibhetri zeLithium-iron-phosphate (iibhetri zeLFP)luhlobo oluthile lwebhetri ye-lithium-ion esebenzisa i-lithium iron phosphate (LiFePO4) njengezinto ze-cathode.
Iibhetri zeLithium LiFePO4 zaziwa ngokuzinza kobushushu bazo, ubomi obude bomjikelo, kunye nokhuseleko.
Zisetyenziswa kakhulu kwizithuthi zombane (ii-EV), kwindawo yokugcina amandla avuselelekayo, nakwezinye izinto apho ukhuseleko kunye nobomi obude bubaluleke kakhulu.
