Ibhetri ye-lithium-ion (ngamanye amaxesha ibhetri ye-Li-ion okanye i-LIB) ilungu lentsapho yeentlobo zebhetri ezihlawulelwayo apho i-lithium ion isuka kwi-electrode engafanelekanga ukuya kwi-electrode efanelekileyo ngexesha lokukhutshwa kunye nokubuyisela emva xa utshaja.
Iibhetri ze-Li-ion zisebenzisa i-lithium compound edibeneyo njengento enye ye-electrode, xa kuthelekiswa ne-metallic lithium esetyenziswe kwibhetri ye-lithium engahlawulekiyo.
I-electrolyte, evumela ukunyakaza kwe-ionic, kunye nee-electrodes ezimbini zizinto ezihambelanayo zeseli ye-lithium-ion. Iibhetri zeLithium-ion zixhaphakile kubathengi be-elektroniki.
Zezinye zezona ntlobo zidumileyo zeebhetri ezinokutshajwa kwakhona kwii-elektroniki eziphathwayo, ezinoxinano oluphezulu lwamandla, akukho siphumo sokukhumbula, kunye nelahleko ecothayo kuphela yentlawulo xa ingasetyenziswa.
Ngaphaya kwee-elektroniki zabathengi, ii-LIBs zikwakhula ekudumeni emkhosini, kwizithuthi zombane kunye nezicelo ze-aerospace.
Ngokomzekelo, iibhetri ze-lithium-ion ziba yinto eqhelekileyo kwiibhetri ze-asidi ezikhokelayo eziye zasetyenziswa ngokwembali kwiinqwelo zegalufa kunye nezithuthi eziluncedo.
Endaweni yeepleyiti ezinzima kunye ne-asidi ye-electrolyte, umkhwa kukusebenzisa iipakethi zebhetri ze-lithium-ion ezilula ezinokubonelela ngombane ofanayo njengeebhetri ze-lead-asidi, ngoko akukho kuguqulwa kwindlela yokuqhuba isithuthi efunekayo.
Ikhemistri, ukusebenza, iindleko kunye neempawu zokhuseleko ziyahluka kwiintlobo ze-LIB.
Izixhobo zombane eziphathwayo zisebenzisa ii-LIBs ezisekwe kwi-lithium cobalt oxide (), enika uxinano lwamandla aphezulu, kodwa inika imingcipheko yokhuseleko, ngakumbi xa yonakele.
I-Lithium iron phosphate (LFP), i-lithium manganese oxide (LMO) kunye ne-lithium nickel manganese cobalt oxide (NMC) zibonelela ngoxinano lwamandla aphantsi, kodwa ubomi obude kunye nokhuseleko lwendalo.
Iibhetri ezinjalo zisetyenziselwa ngokubanzi izixhobo zombane, izixhobo zonyango kunye nezinye iindima. I-NMC ingakumbi ikhuphisana eliphambili kwizicelo zemoto.
ILithium nickel cobalt aluminiyam oxide (NCA) kunye ne-lithium titanate (LTO) luyilo olukhethekileyo olujolise kwiindima ezithile ze-niche.
Iibhetri zeLithium-ion zinokuba yingozi phantsi kweemeko ezithile kwaye zinokubeka ingozi yokhuseleko njengoko ziqulathe, ngokungafaniyo nezinye iibhetri ezinokutshajwa kwakhona, i-electrolyte enokutsha kwaye zigcinwa zicinezelekile.
Ngenxa yoku, imigangatho yovavanyo yezi bhetri ingqongqo kuneebhetri ze-acid-electrolyte, ifuna zombini uluhlu olubanzi lweemeko zovavanyo kunye novavanyo olongezelelweyo lwebhetri.
Oku kusabela kwiingozi ezixeliweyo kunye nokusilela, kwaye kuye kwakho ukukhunjuzwa okunxulumene nebhetri ziinkampani ezithile.
NdinguJoost Nusselder, umseki weZixhobo zeGqirha, umthengisi womxholo, kunye notata. Ndiyathanda ukuzama izixhobo ezitsha, kwaye kunye neqela lam ndiye ndenza amanqaku ebhlog anzulu ukusukela ngo-2016 ukunceda abafundi abathembekileyo ngezixhobo kunye neengcebiso zokwenza.
