Abantu bahlala bendibuza, yintoni engcono phakathi kwebhetri ye-lithium ion kunye nebhetri ye-lithium ion?Ukuba ufunda oku kulandelayo, uya kufumana impendulo.
Ibhetri ye-lithium ion inokwahlulwa ibe yibhetri ye-lithium ion, ibhetri ye-lithium ion okanye ibhetri yeplastiki ye-lithium ion ngokwee-electrolyte ezahlukeneyo ezisetyenziswa kwibhetri ye-lithium ion eqhelekileyo. ion, kunye nemigaqo yabo ngokusisiseko efanayo.Kodwa umahluko ongundoqo phakathi kwabo kuxhomekeke izinto ekrwada izisombululo electrolyte azifani, ibhetri ulwelo lithium kunyulwe isisombululo ulwelo electrolyte, kwaye ibhetri lithium polymer kunyulwe eqinileyo polymer electrolyte eliphezulu. isisombululo.
Enyanisweni, umxholo wenkcazo yebhetri ye-lithium ion ixhaphake.Ngeli xesha, ndiya kukunika isingeniso esifutshane sebhetri ye-lithium kuwe.
Ibhetri ye-lithium ibhekisela ekusebenziseni ibhetri isinyithi se-lithium okanye i-lithium alloy njengento ye-anode, sebenzisa isisombululo se-electrolyte esingenamanzi.Ibhetri ye-lithium ngokubanzi iquka ibhetri yensimbi ye-lithium kunye nebhetri ye-lithium ion.Ibhetri yesinyithi ye-lithium ngokuqhelekileyo ibhekisela ekusebenziseni ibhetri ye-manganese dioxide njengento efanelekileyo, isinyithi se-lithium okanye isinyithi sayo se-alloy njengento engalunganga, ukusetyenziswa kwesisombululo se-electrolyte esingenamanzi.Ibhetri ye-ion ye-lithium ngokubanzi ibhekisela ekusebenziseni ibhetri ye-lithium alloy metal oxide njengento efanelekileyo ye-electrode, igraphite njengento engafanelekanga ye-electrode, sebenzisa isisombululo se-electrolyte engekho emanzini. kwibhetri ye-lithium ion.Ngoko ke, ibhetri ye-lithium engaphezulu ibhekisela kwibhetri ye-lithium ion.
Ibhetri yeLithium ikwahlulwe ibe yibhetri ye-lithium engamanzi kunye nebhetri ephezulu yepolymer lithium iindidi ezimbini.Ukuze ukhangele amandla aluhlaza, ilizwe ngalinye liphanda i-lithium kunye nebhetri ye-lithium ngoku, ijonge phambili ukuyisebenzisa ukuze ithathe indawo yezibonelelo ezingahlaziywayo.Njengoko zilinganiselwe emhlabeni, ziya kukhupha izinto ezininzi eziyingozi xa sizisebenzisa.
Ibhetri ye-lithium yokuqhuba ibhetri ye-lithium yolwelo njengoko sisazi sonke.Ibhetri ye-lithium yanamhlanje ibhengezwe ukuba isetyenziswe kubomi bethu bemihla ngemihla.Umzekelo, ibhasi eqhelekileyo, itshintshwa ngokuthe ngcembe ziimoto eziqhuba i-lithium.Olu hlobo lwebhasi alulula nje ukucoca kunye nokukhuselwa kokusingqongileyo ngaphezu kwebhasi eyayisebenzisa igesi ngaphambili ngokubhekiselele kumbane kunye namandla, kodwa kunye nokuzinza ngakumbi kunye nokuzola kwinkqubo yokuqhuba.
Ngoku siye saqonda i-theory kunye nodidi lwebhetri ye-lithium, kunye nokwahlukana phakathi kwebhetri ye-lithium ion kunye ne-polymer lithium ion ibhetri.Makhe sithelekise iiyantlukwano ezimbini kuqala, ngokusekelwe kuthelekiso sinokufikelela kwizigqibo ngokukhawuleza.
Uthelekiso phakathi kwebhetri ye-polymer lithium kunye nebhetri ye-lithium ion.
▼Kwinqanaba loyilo lwemodeli
Ibhetri ye-lithium ion ye-polymer ingenziwa ngokwezifiso ngokweemfuno zabathengi, isitshixo singenxa yesisombululo sayo se-electrolyte engeyiyo yolwelo, isisombululo esiqinileyo se-electrolyte sinenzuzo ngakumbi kulondolozo lwexesha elide lwe-polymer lithium ion ibhetri.Ibhetri ye-Lithium ion okanye ibhetri ye-lithium elulwelo, sisisombululo se-electrolyte engamanzi, ngoko kufuneka kubekho imeko eyomeleleyo yokubamba i-electrolyte yebhetri ye-lithium njengopakisho lwecoil yesibini, kwaye olu hlobo lokupakisha lunomda othile ekubumbeni kwaye luphucule. ubunzima bubonke.
▼Kwi-voltage engundoqo yokusebenza
Ngenxa yebhetri ye-lithium ye-polymer isebenzisa izinto eziluhlaza ze-polymer, inokuvelisa ukubunjwa kabini kwiseli ye-lithium ukufezekisa uxinzelelo oluphezulu.Kodwa umthamo omfutshane wesekethe yeseli ye-lithium yebhetri ye-lithium kukuba kufuneka udibanise iiseli ezininzi ze-lithium kunye kuthotho ukuvelisa iqonga elisebenzayo loxinzelelo oluphezulu ukuba ufuna ukufezekisa uxinzelelo oluphezulu kwisicelo esithile.
▼Kwi-REDOX enokwenzeka
Kwi-polymer ibhetri ye-lithium, i-ion echanekileyo yesisombululo esiqinileyo se-electrolyte ine-conductivity ephantsi, kwaye ukongezwa kwezigcini kwisisombululo se-electrolyte kunempembelelo ebalulekileyo ekuphuculeni ukuqhutyelwa.Kuphela i-ion conductivity enhle iphuculwe kancinane, kwaye ngokungafaniyo nebhetri ye-lithium, i-conductivity yayo izinzile, akukho lula ukubandezeleka kumgangatho wokulimala kwezinto ezincedisayo.
▼Kwinkqubo yemveliso
Ibhetri ye-lithium ion i-polymer incinci kwaye ibhetri ye-lithium iyaqina, umda wokusetyenziswa kwebhetri ye-lithium kunye neshishini linokwandiswa libanzi ngenxa yobuninzi bebhetri ye-lithium.
Njengoko ibhetri ye-lithium ye-polymer kunye nebhetri ye-lithium ion inemilo eyahlukeneyo yezisombululo ze-electrolyte, zineendlela ezahlukeneyo zokusetyenziswa eziphambili.Zombini zineenzuzo kumashishini ahlukeneyo.
