Yintoni iisinyithi se-lithiumIntshayelelo kumgaqo wokusebenza kunye neenzuzo zebhetri yesinyithi ye-lithium

Ibhetri yesinyithi yeLithium luhlobo lwebhetri kusapho lwebhetri yeLithium. Igama layo elipheleleyo yibhetri yeLithium Iron phosphate yeLithium ion. Izinto zeCathode ikakhulu yiLithium Iron phosphate. Ngenxa yokuba ukusebenza kwayo kufanelekile kakhulu kwiindlela zombane, ikwabizwa ngokuba yiLithium Iron Power Battery. (emva koku ibizwa ngokuba yiLithium Iron Battery)

Umgaqo wokusebenza webhetri yesinyithi ye-lithium (LiFePO4)
Ulwakhiwo lwangaphakathi lwebhetri yeLiFePO4: ILiFePO4 enesakhiwo se-olivine ngasekhohlo isetyenziswa njengepali ye-positive yebhetri, eqhagamshelwe ngefoyile ye-aluminiyam kunye nepali ye-positive yebhetri. Embindini kukho i-polymer diaphragm, eyahlula ipali ye-positive kwipali ye-negative. Nangona kunjalo, i-lithium ion iLi+ ingadlula kodwa i-electronic e – ayinakudlula. Ngasekunene kukho ipali ye-negative yebhetri eyenziwe ngekhabhoni (igrafiti), eqhagamshelwe ngefoyile yobhedu kunye nepali ye-negative yebhetri. I-electrolyte yebhetri iphakathi kweziphelo eziphezulu nezisezantsi zebhetri, kwaye ibhetri ivalwe ngeqokobhe lesinyithi.

Xa ibhetri yeLiFePO4 itshajiwe, i-lithium ion Li+kwi-electrode echanekileyo ifudukela kwi-electrode engalunganga nge-membrane yepolymer; Ngexesha lenkqubo yokukhupha, i-lithium ion Li+kwi-electrode engalunganga ifudukela kwi-electrode echanekileyo nge-diaphragm. Ibhetri yeLithium-ion ibizwa ngokufuduka kwee-ion ze-lithium ngexesha lokutshaja nokukhupha.

Ukusebenza okuphambili kwebhetri yeLiFePO4
I-voltage eqhelekileyo yebhetri yeLiFePO4 yi-3.2 V, i-voltage yokutshaja yokugqibela yi-3.6 V, kwaye i-voltage yokukhutshelwa kokuphela yi-2.0 V. Ngenxa yomgangatho owahlukileyo kunye nenkqubo yezinto ze-electrode ezilungileyo nezingalunganga kunye nezixhobo ze-electrolyte ezisetyenziswa ngabavelisi abahlukeneyo, ukusebenza kwazo kuya kwahluka kancinci. Umzekelo, umthamo webhetri wemodeli efanayo (ibhetri eqhelekileyo kwiphakheji efanayo) yahlukile kakhulu (10% ~ 20%).

Iingenelo zeibhetri yesinyithi ye-lithium
Xa kuthelekiswa neebhetri zemveli ze-lead-acid, iibhetri ze-lithium-ion zineengenelo ezibalulekileyo kwi-voltage yokusebenza, uxinano lwamandla, ubomi bomjikelo, njl. Xa kuthelekiswa nebhetri yemveli ye-lead-acid, inezi nzuzo zilandelayo: uxinano lwamandla aphezulu, ukhuseleko oluqinileyo, ukusebenza kakuhle kobushushu obuphezulu, amandla aphezulu, ubomi bomjikelo omde, ubunzima obuphantsi, iindleko zokuqinisa igumbi lomatshini ezonga imali, ubungakanani obuncinci, ubomi bebhetri obude, ukhuseleko olulungileyo, njl.
