Abantu bavame ukungibuza, yikuphi okungcono phakathi kwebhethri ye-polymer lithium ion nebhethri ye-lithium ion?Uma ufunda okulandelayo, uzothola impendulo.
Ibhethri le-lithium ion lingahlukaniswa libe ibhethri le-lithium ion eliwuketshezi, ibhethri le-lithium ion le-polymer noma ibhethri le-lithium ion lepulasitiki ngokuvumelana nama-electrolyte ahlukene asetshenziswa ebhethrini elivamile le-lithium ion.Ibhethri ye-lithium ion ye-polymer isebenzisa into efanayo ye-cathode njengempahla eluhlaza ye-lithium enguketshezi ion, nezimiso zabo ngokuyisisekelo ziyefana.Kodwa umehluko oyinhloko phakathi kwazo uncike ezintweni ezingavuthiwe zezixazululo ze-electrolyte azifani, ibhethri ye-lithium ewuketshezi ingakhethwa isisombululo se-electrolyte ewuketshezi, futhi ibhethri ye-lithium ye-polymer ikhethwe okuqinile kwe-polymer electrolyte ephezulu. isisombululo.
Eqinisweni, okuqukethwe kwencazelo yebhethri ye-lithium ion kuvame kakhulu.Lesi sikhathi, ngizokunikeza isingeniso esifushane sebhethri ye-lithium kuwe.
Ibhethri ye-lithium ibhekisela ekusebenziseni ibhethri insimbi ye-lithium noma i-lithium alloy njengento ye-anode, sebenzisa isixazululo se-electrolyte esinganamanzi.Ibhethri ye-lithium evamile ihlanganisa ibhethri ye-lithium yensimbi nebhethri ye-lithium ion.Ibhethri yensimbi ye-lithium ngokuvamile ibhekisela ekusebenziseni ibhethri manganese dioxide njengento enhle, insimbi ye-lithium noma insimbi yayo yengxubevange njengento engeyinhle, ukusetshenziswa kwesisombululo se-electrolyte esinganamanzi.Ibhethri ye-lithium ion ngokuvamile ibhekisela ekusebenziseni ibhethri i-lithium alloy metal oxide njengento eqondile ye-electrode, i-graphite njengento engalungile ye-electrode, sebenzisa isixazululo se-electrolyte esinganamanzi. kubhethri ye-lithium ion.Ngakho-ke, ububanzi bebhethri ye-lithium bubhekisela kubhethri ye-lithium ion.
Ibhethri ye-lithium nayo ihlukaniswe yaba ibhethri ye-lithium ye-lithium kanye nebhethri ephezulu ye-polymer lithium izigaba ezimbili.Ukuze ufune amandla aluhlaza, izwe ngalinye licwaninga ibhethri ye-lithium ne-lithium njengamanje, ibheke ngabomvu ukuyisebenzisela ukufaka esikhundleni sezinsiza ezingavuseleleki.Njengoba zilinganiselwe emhlabeni, zizokhipha izinto eziningi eziyingozi lapho sizisebenzisa.
Ibhethri ye-lithium yamandla okushayela ibhethri ye-lithium ewuketshezi njengoba sazi sonke.Ibhethri ye-lithium yanamuhla imenyezelwe ukuthi izosetshenziswa ekuphileni kwethu kwansuku zonke.Isibonelo, ibhasi elivamile, kancane kancane lishintshwa yizimoto zokushayela ze-lithium.Lolu hlobo lwebhasi akulula nje ukulihlanza kanye nokuvikela imvelo okwengeziwe kunebhasi elake lasebenzisa igesi ngaphambili mayelana nogesi namandla, kodwa futhi lizinze futhi lithule lapho lishayela.
Manje siye saqonda inkolelo kanye nesigaba sebhethri ye-lithium, kanye nomehluko phakathi kwebhethri ye-lithium ion nebhethri ye-polymer lithium ion.Into elandelayo sizoxoxa ngayo ngokuthi iyiphi ibhethri ye-lithium ye-polymer nebhethri ye-lithium enamandla.Ake siqhathanise le mehluko emibili kuqala, ngokusekelwe esiqhathanisweni singafinyelela iziphetho ngokushesha.
Ukuqhathanisa phakathi kwebhethri ye-polymer lithium nebhethri ye-lithium ion.
▼Ezingeni lokuklama amamodeli
Ibhethri ye-polymer lithium ion ingenziwa ngokwezifiso ngokwezidingo zekhasimende, ukhiye kungenxa yesisombululo salo se-electrolyte esingewona uketshezi, isixazululo esiqinile se-electrolyte sinenzuzo kakhulu ekugcinweni kwesikhathi eside kwebhethri ye-polymer lithium ion.Ibhethri ye-lithium ion noma ibhethri le-lithium eliwuketshezi, iyisixazululo esiwuketshezi se-electrolyte, ngakho-ke kufanele kube necala eliqinile lokubamba i-electrolyte yebhethri ye-lithium njengokufakwa kwekhoyili yesibili, futhi lolu hlobo lwendlela yokupakisha lunomkhawulo othile ekubumbeni futhi luthuthuke. isisindo esiphelele.
▼Ku-voltage eyinhloko yokusebenza
Ngenxa yebhethri ye-lithium ye-polymer isebenzisa izinto zokusetshenziswa ze-polymer, ingakhiqiza ukwakheka kongqimba oluphindwe kabili kuseli ye-lithium ukuze kuzuzwe ingcindezi ephezulu.Kodwa umthamo wesifunda esifushane weseli ye-lithium yebhethri ye-lithium ukuthi kufanele uxhume amaseli e-lithium amaningana ndawonye ochungechungeni ukuze ukhiqize isiteji sokusebenza sokucindezela okuphezulu uma ufuna ukufeza ukucindezela okuphezulu kuhlelo lokusebenza oluthile.
▼Ngamandla e-REDOX
Kubhethri ye-lithium ye-polymer, ama-ion alungile esisombululo se-electrolyte esiqinile sinokusebenza okuphansi, futhi ukungezwa kwezilondolozi kusixazululo se-electrolyte kunomphumela obalulekile ekuthuthukiseni ukuqhutshwa kwe-conductivity.Kuyinto enhle kuphela ion conductivity ngcono kancane, futhi ngokungafani nebhethri lithium, conductivity yayo uzinzile, akulula ukuhlupheka kusukela izinga umonakalo asizayo impahla.
▼Enqubweni yokukhiqiza
Ibhethri le-lithium ion le-polymer lincanyana futhi ibhethri le-lithium lishubile, ububanzi bokusetshenziswa kwebhethri ye-lithium kanye nemboni inganwetshwa banzi ngenxa yokuqina kwebhethri ye-lithium.
Njengoba ibhethri ye-lithium ye-polymer nebhethri ye-lithium ion inezimo ezihlukene zezixazululo ze-electrolyte, zinokusetshenziswa okuhlukile okuyinhloko.Zombili zinezinzuzo ezimbonini ezahlukene.
