Izinto eziluncedo ze-Super Capacitor kwi-Automotive Applications

Kwiminyaka yakutshanje, ngokuthandwa kweemoto, iintlobo kunye nobuninzi beemveliso ze-elektroniki kwizithuthi ziyanda.Uninzi lwezi mveliso zixhotyiswe ngeendlela ezimbini zonikezelo lwamandla, enye isuka kwimoto ngokwayo, amandla abonelelwa ngojongano oluqhelekileyo lwesithuthi.Enye iphuma kumandla okugcina, asetyenziselwa ukugcina isixhobo sisebenza emva kokuba umbane wesilayidi secuba ucinyiwe.Okwangoku, uninzi lweemveliso zombane zeemoto zisebenzisa iibhetri ze-lithium-ion njengemithombo yamandla egcinayo.Kodwa ii-supercapacitors ngokuthe ngcembe zithatha indawo yeebhetri ze-lithium-ion.Ngoba?Masiqale siqonde ukuba zisebenza njani izixhobo ezibini zokugcina amandla.

Zisebenza njani ii-supercapacitors:

Ii-Supercapacitors zisebenzisa i-carbon-based actives, i-carbon conductive emnyama kunye ne-binder exutywe njengempahla ye-pole piece, kwaye isebenzise i-electrolyte epolarized ukufunxa ii-ion ezintle kunye nezingalunganga kwi-electrolyte ukwenza isakhiwo sombane esiphindwe kabini sokugcina amandla.Akukho mpendulo yekhemikhali eyenzekayo ngexesha lenkqubo yokugcina amandla.

Umgaqo osebenzayo webhetri ye-lithium:

Iibhetri zeLithium zixhomekeke kakhulu ekuhambeni kwee-ion ze-lithium phakathi kwe-electrode efanelekileyo kunye ne-negative ukuze isebenze.Ngexesha lokutshaja kunye nokukhupha, ii-ion ze-lithium ziyadityaniswa kwaye zichanelwe ngasemva naphambili phakathi kwee-electrode ezimbini.Ngexesha lokutshaja, i-ion ze-lithium zichithwa kwi-electrode efanelekileyo kwaye zidibanise kwi-electrode engafanelekanga nge-electrolyte, kwaye i-electrode engafanelekanga ikwimeko ecebileyo ye-lithium.Inkqubo yokutshaja kunye nokukhupha i-chemical reaction.

Ukususela kwimigaqo yokusebenza kwezi zinto zimbini zokugcina amandla, kugqitywe ukuba kutheni ukusetyenziswa kwee-supercapacitors kwiirekhodi zokuqhuba kunokutshintsha iibhetri ze-lithium-ion.Oku kulandelayo luncedo lwee-supercapacitors ezisetyenziswa kwiirekhodi zokuqhuba:

I-1) Umgaqo osebenzayo weebhetri ze-lithium-ion yisitoreji samandla ekhemikhali, kwaye kukho iingozi ezifihliweyo.Inzuzo kukuba xa ushiya umbane wesithuthi, usenokuba nexesha elithile lobomi bebhetri, kodwa i-lithium ion kunye ne-electrolytes ziyatsha kwaye ziqhume.Iibhetri ze-lithium-ion, xa sele zifutshane, zinokutshisa okanye ziqhume.I-supercapacitor iyinxalenye ye-electrochemical, kodwa akukho mpendulo yekhemikhali eyenzekayo ngexesha lenkqubo yokugcina amandla.Le nkqubo yokugcina amandla ibuyiselwa umva, kwaye ngokuchanekileyo ngenxa yoko ukuba i-supercapacitor inokuhlawulwa ngokuphindaphindiweyo kwaye ikhutshwe ngezigidi zamaxesha.

I-2) Ubuninzi bamandla be-supercapacitors buphezulu.Oku kungenxa yokuba ukuchasana kwangaphakathi kwee-supercapacitors kuncinci, kwaye ii-ion zinokuqokelelwa ngokukhawuleza kwaye zikhutshwe, eziphakamileyo kakhulu kunezinga lamandla ebhetri ye-lithium-ion, okwenza ukutshaja kunye nokukhupha isantya se-supercapacitors phezulu.

3) Ukumelana nokushisa okuphezulu kweebhetri ze-lithium-ion akulungile.Ngokuqhelekileyo, izinga lokukhusela liphezulu kune-60 degrees Celsius.Kwimeko yokushisa okuphezulu kwelanga okanye iimeko zesiphaluka ezimfutshane, kulula ukubangela ukutshisa okuzenzekelayo kunye nezinye izinto.I-supercapacitor inoluhlu olubanzi lobushushu bokusebenza ukuya kuthi ga kwi -40 ℃ ~ 85 ℃.

4) Ukusebenza kuzinzile kwaye ixesha lokujikeleza lide.Ekubeni ukutshaja kunye nokukhutshwa kwe-supercapacitor yinkqubo yomzimba kwaye ayibandakanyi inkqubo yeekhemikhali, ilahleko incinci kakhulu.

I-5) I-Super capacitors iluhlaza kunye nokusingqongileyo.Ngokungafani neebhetri ze-lithium-ion, i-supercapacitors ayisebenzisi isinyithi esinzima kunye nezinye izinto eziyingozi.Ngethuba nje ukhetho kunye noyilo lunengqiqo, akukho mngcipheko wokuqhuma kwe-bulge phantsi kweqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu ngexesha lokusetyenziswa, olufanelekileyo kwiimeko zokusetyenziswa kwezithuthi.

I-6) I-supercapacitor inokudityaniswa, ngoko akukho ngxaki njengoqhagamshelwano olubuthathaka lwebhetri.

I-7) Akukho mjikelezo okhethekileyo wokutshaja kunye nokulawula ukukhutshwa kwesekethe kuyadingeka.

I-8) Xa kuthelekiswa neebhetri ze-lithium-ion, i-supercapacitors ayinayo impembelelo engafanelekanga kwixesha labo lokusetyenziswa ngenxa yokugqithiswa kunye nokugqithisa.Ewe kunjalo, ii-supercapacitors zikwanazo nezingeloncedo zexesha elifutshane lokukhupha kunye notshintsho olukhulu lwamandla ombane ngexesha lenkqubo yokukhupha, ke ezinye izihlandlo ezithile kufuneka zisetyenziswe kunye neebhetri.Ngamafutshane, iingenelo ze-supercapacitors zifanelekile kwiimeko zokusetyenziswa kweemveliso zemoto, kwaye irekhodi lokuqhuba ngumzekelo omnye.

Umxholo ongentla uluncedo lwe-super capacitor kwizicelo zeemoto.Ngethemba iluncedo kubantu abafuna ukufunda ngee-super capacitors.I-JYH HSU (JEC) Electronics Ltd (okanye i-Dongguan Zhixu Electronic Co., Ltd.) iye yazinikela kuphando kunye nophuhliso, ukuveliswa kunye nokuthengiswa kwee-capacitors zokhuseleko iminyaka engaphezu kwe-30.
