Yintoni iintsimbi ye-lithiumibhetri?Intshayelelo kumgaqo wokusebenza kunye neenzuzo zebhetri yentsimbi ye-lithium

Ibhetri yentsimbi ye-lithium luhlobo lwebhetri kwintsapho yebhetri ye-lithium.Igama layo elipheleleyo lithi lithium iron phosphate lithium ion battery.Izinto ze-cathode ikakhulu i-lithium iron phosphate.Ngenxa yokuba ukusebenza kwayo kulungele ukusetyenziswa kwamandla, ikwabizwa ngokuba yi "lithium iron power battery".(emva koku kuthiwa yi "lithium iron battery")

Umgaqo osebenzayo webhetri yentsimbi ye-lithium (LiFePO4)
Isakhiwo sangaphakathi se-LiFePO4 ibhetri: I-LiFePO4 kunye nesakhiwo se-olivine ngakwesobunxele sisetyenziswe njengesibonda esilungileyo sebhetri, esidibaniswe ne-aluminium foil kunye ne-potive pole yebhetri.Embindini kukho i-polymer diaphragm, eyahlula isibonda esilungileyo kwipali engafanelekanga.Nangona kunjalo, i-lithium ion Li + inokudlula kodwa i-electronic e - ayikwazi.Ngasekunene yipali engafanelekanga yebhetri eyenziwe ngekhabhoni (graphite), edityaniswe ngefoyile yobhedu kunye nepali engalunganga yebhetri.I-electrolyte yebhetri iphakathi kweziphelo eziphezulu nezisezantsi zebhetri, kwaye ibhetri ivalwe ngeqokobhe lentsimbi.

Xa ibhetri ye-LiFePO4 ihlawuliswa, i-lithium ion Li + kwi-electrode efanelekileyo ifudukela kwi-electrode engafanelekanga nge-polymer membrane;Ngethuba lenkqubo yokukhupha, i-lithium ion Li + kwi-electrode engafanelekanga ifudukela kwi-electrode efanelekileyo nge-diaphragm.Ibhetri ye-lithium-ion ibizwa ngokuba yimfuduko ye-lithium ion ngexesha lokutshaja kunye nokukhupha.

Ukusebenza okuphambili kwebhetri yeLiFePO4
I-voltage yegama lebhetri ye-LiFePO4 yi-3.2 V, i-voltage yokuphela kwentlawulo yi-3.6 V, kwaye i-voltage yokuphela yokukhupha i-2.0 V. Ngenxa yomgangatho ohlukeneyo kunye nenkqubo yezinto eziphathekayo kunye nezixhobo ze-electrode kunye nezinto ze-electrolyte ezisetyenziswa ngabavelisi abahlukeneyo, ukusebenza kwabo. iya kwahluka noko.Umzekelo, umthamo webhetri yemodeli efanayo (ibhetri esemgangathweni kwiphakheji enye) yahluke kakhulu (10% ~ 20%).

Izinto ezilungileyo zeibhetri yentsimbi ye-lithium
Xa kuthelekiswa neebhetri zemveli ze-asidi, iibhetri ze-lithium-ion zineenzuzo ezibalulekileyo kumbane osebenzayo, ubuninzi bamandla, ubomi bomjikelezo, njl. ukusebenza kobushushu obuphezulu, ukuphuma kwamandla aphezulu, ubomi bomjikelo omde, ubunzima obulula, ukonga iindleko zokuqinisa igumbi lomatshini, ubungakanani obuncinci, ubomi bebhetri obude, ukhuseleko olulungileyo, njl.
