1 Ibhetri yeLithium
Ibhetri ye-lithium luhlobo lwebhetri esebenzisa isinyithi se-lithium okanye i-lithium alloy njengento engafanelekanga ye-electrode kwaye isebenzisa isisombululo esingenamanzi se-electrolyte.Amandla ayo athile aphezulu kakhulu, kodwa aneengozi ezinokubakho zokhuseleko.Izinto ezilungileyo ze-electrode zebhetri ye-lithium yi-manganese dioxide okanye i-thionyl chloride, kunye ne-electrode engafanelekanga i-lithium.Emva kokuba ibhetri idityanisiwe, ibhetri inamandla ombane kwaye ayifuni kutshajiswa.Olu hlobo lwebhetri lunokuhlawuliswa, kodwa ukusebenza komjikelo akulunganga.Ngexesha lokutshaja kunye nokukhutshwa komjikelo, kulula ukwenza i-lithium dendrites, okukhokelela kwisiphaluka esifutshane sangaphakathi sebhetri, ngoko ngokubanzi olu hlobo lwebhetri aluvunyelwe ukuhlawuliswa.
Ibhetri yeLithium Ion
Ibhetri yeLithium Ion (iNgonyama) ibhekisa kwibhetri egcwalisekayo esebenzisa i-lithium ion njengezinto ezisebenzayo.Xa ibhetri ikhutshwe kwi-voltage yokuphelisa, inokuphinda itshajwe ukubuyisela imeko ngaphambi kokukhutshwa.Iibhetri ze-lithium-ion zigcina kwaye zikhulule i-ion ze-lithium ngokusebenzisa izinto ezisebenzayo ezigqunywe kwi-electrode, oko kukuthi, ukugcina amandla ombane ngokusebenzisa i-deintercalation ye-lithium ion kwizinto ezisebenzayo ze-electrode.Undoqo weebhetri ze-lithium ion ngokwenene kukusebenzisa umahluko woxinaniso lwe-lithium ion yokugcina amandla kunye nokukhupha.Ayikho i-lithium yensimbi kwibhetri, ngoko ukhuseleko lwayo lungcono kuneebhetri ze-lithium, kwaye amandla athile eebhetri ze-lithium ion aphantsi kuneebhetri ze-lithium.amandla.
3 Umahluko phakathi kwebhetri ye-lithium kunye nebhetri ye-lithium ion
Kwithiyori, iibhetri ze-lithium kunye neebhetri ze-lithium-ion zineengcamango ezahlukeneyo.Ibhetri esebenzisa intsimbi ye-lithium njengesixhobo se-electrode ibizwa ngokuba yibhetri ye-lithium, eyebhetri yokuqala.Inokulahlwa emva kokusetyenziswa kwaye ayinakuphinda isetyenziswe.Izinto ezintle ze-electrode ze-lithium ion ibhetri yi-lithium cobalt oxide (okanye enye i-lithium metal oxide), kunye ne-electrode engafanelekanga i-carbon material.Ukuze ukwahlula kwibhetri ye-lithium yendabuko, ibizwa ngokuba yi-lithium ion ibhetri.Iibhetri zeLithium-ion ziibhetri zesibini ezinokutshajwa kwaye ziphinde zisetyenziswe, oko kukuthi, iibhetri zethu eziqhelekileyo ezinokutshajwa kwakhona.Kubomi bemihla ngemihla, abantu abaninzi babhidanisa ezi zimbini kwaye babize iibhetri ze-lithium-ion ezifinyeziweyo njengeebhetri ze-lithium, ezikhokelela ekubhidekeni kweengcamango.
Kukho umahluko omkhulu kakhulu phakathi kweebhetri ze-lithium kunye neebhetri ze-lithium ion electrochemically, oko kukuthi, umbane wokukhupha.Ngokuqhelekileyo, iqonga lokukhupha ibhetri ye-lithium yi-3.0 V, ngoko i-voltage ye-lithium yebhetri yeekhamera ezininzi yi-3.0 V, kunye ne-backup lithium ibhetri yefowuni yeselula nayo i-3.0 V. I-avareji yokukhupha i-lithium-ion iibhetri ziphakathi kwe-3.6 kunye ne-3.8 V. Okwangoku, uninzi lweebhetri ze-lithium-ion zefowuni zine-voltage ye-3.7 V, kwaye ezinye sele zi-3.8 V. Lo mbane wegama ungasetyenziselwa ukwahlula iibhetri ze-lithium-ion kwi-lithium. iibhetri.Ebomini, akukho ngqongqo ukubiza iibhetri ezisetyenziswa kwiikhamera, ii-laptops kunye neefowuni eziphathwayo njengeebhetri ze-lithium ezihlaziyiweyo okanye iibhetri ze-lithium.Ibizwa ngokuba ziibhetri ze-lithium ion kwaye ifinyeziwe njenge-Li-ion okanye i-Li +.Isishunqulelo sebhetri ye-lithium ngu-Li, ngaphandle kwe- + (isimboli ye-ion entle).
