Kwihlabathi elikhula ngokukhawuleza logcino lwamandla, zimbini iindidi zeebhetri bezisenza izihloko eziphambili:Iibhetri zesodium-ion (SIBs)kwayeIibhetri zeLithium-iron-phosphate (iibhetri zeLFP). Zombini iteknoloji yebhetri ye-sodium kunye ne-lithium iteknoloji yebhetri ithembisa iteknoloji, kodwa ineempawu ezicacileyo ezenza ukuba zilungele izicelo ezahlukeneyo. Kweli nqaku, siza kuphonononga ukuba zeziphi iibhetri ze-sodium-ion kunye ne-lithium-iron-phosphate, kwaye emva koko uthelekise ukungafani kwazo ngokusekelwe kwiziphumo zophando lwakutsha nje.
Ziziphi iibhetri zeSodium-ion (SIBs)?
Iibhetri zesodium-ion (SIBs)luhlobo lwebhetri ehlaziywayo esebenzisa i-sodium ion (Na+) njengabathwali bentlawulo. I-sodium ininzi kwaye ayibizi, yenza i-SIBs iteknoloji entsha yebhetri yokutshintsha i-lithium.
Ii-SIBs ziqhele ukusebenzisa i-hard carbon njengesixhobo se-anode, esahlukileyo kwigraphite esetyenziswa rhoqo kwiiLIBs. Izinto ze-cathode ziyakwazi ukuhluka, kodwa zihlala ziyilelwe ukuba zifake ubungakanani obukhulu be-sodium ions xa kuthelekiswa ne-lithium ion.
Zeziphi iibhetri ze-LFP (Ibhetri ye-iron-phosphate)?
Iibhetri zeLithium-iron-phosphate (iibhetri zeLFP)i-subtype yokugcina ibhetri ye-lithium-ion esebenzisa i-lithium iron phosphate (LiFePO4) njengento ye-cathode.
Iibhetri zeLithium LiFePO4 ziyaziwa ngokuzinza kwazo ngokushushu, ubomi bomjikelo omde, kunye nokhuseleko.
Zisetyenziswa ngokubanzi kwizithuthi zombane (EVs), ukugcinwa kwamandla avuselelekayo, kunye nezinye izicelo apho ukhuseleko kunye nokuphila ixesha elide kubaluleke kakhulu.
