Ibhethri ye-lithium-ion isebenza kanjani?Iziphi izinzuzo enazo kunebhethri elinomthofu?Isitoreji sebhethri ye-lithium-ion sikhokha nini?A ibhethri ye-lithium-ion(okufushane: ibhethri ye-lithiumion noma ibhethri ye-Li-ion) igama elijwayelekile lama-accumulators asekelwe kumakhemikhali e-lithium kuzo zonke izigaba ezintathu, ku-electrode engalungile, ku-electrode ephozithivu kanye naku-electrolyte, iseli le-electrochemical.Ibhethri ye-lithium-ion inamandla athile aphezulu uma iqhathaniswa nezinye izinhlobo zamabhethri, kodwa idinga amasekhethi okuvikela ngogesi ezinhlelweni eziningi, njengoba isabela kabi ekukhishweni okujulile nokushajwa ngokweqile.Amabhethri elanga e-lithium ion ashajwa ngogesi ovela kusistimu ye-photovoltaic futhi aphinde akhishwe njengoba kudingeka.Isikhathi eside, amabhethri okuhola ayebhekwa njengesixazululo esifanelekile samandla elanga kule njongo.Kodwa-ke, ngokusekelwe kumabhethri e-lithium-ion anezinzuzo ezinkulu, nakuba ukuthengwa kusahlotshaniswa nezindleko ezengeziwe, kodwa, ezibuyiselwayo ngokusetshenziswa okuhlosiwe.Isakhiwo Sobuchwepheshe Nokuziphatha Kwesitoreji Samandla Amabhethri e-Lithium-ionAmabhethri e-lithium-ion awahlukani ngokuyisisekelo kusukela kumabhethri e-lead-asidi esakhiweni sawo esijwayelekile.Isithwali sokushaja kuphela esihlukile: Uma ibhethri ishajwa, i-lithium ion "iyafuduka" isuka ku-electrode ephozithivu iye ku-electrode engeyinhle yebhethri futhi ihlale "igcinwe" lapho kuze kube yilapho ibhethri likhishwa futhi.Izikhombi ze-graphite ezisezingeni eliphezulu zivame ukusetshenziswa njengama-electrode.Kodwa-ke, kukhona futhi okuhlukile okunabaqhubi bensimbi noma abaqhubi be-cobalt.Ngokuya ngama-conductor asetshenzisiwe, amabhethri e-lithium-ion azoba nama-voltage ahlukene.I-electrolyte ngokwayo kufanele ingabi namanzi ebhethrini le-lithium-ion njengoba i-lithium namanzi kubangela ukusabela okunodlame.Ngokungafani nabanduleli bawo be-lead-acid, amabhethri e-lithium-ion esimanje (cishe) awanayo imiphumela yenkumbulo noma azikhiphe ngokwawo, futhi amabhethri e-lithium-ion agcina amandla awo aphelele isikhathi eside.Amabhethri okugcina amandla e-lithium-ion ngokuvamile ahlanganisa izakhi zamakhemikhali i-manganese, i-nickel ne-cobalt.I-Cobalt (igama lamakhemikhali: i-cobalt) iyisici esingavamile ngakho-ke yenza ukukhiqizwa kwamabhethri e-Li abize kakhulu.Ngaphezu kwalokho, i-cobalt iyingozi emvelweni.Ngakho-ke, kunemizamo eminingi yocwaningo yokukhiqiza impahla ye-cathode yamabhethri e-lithium-ion high-voltage ngaphandle kwe-cobalt.Izinzuzo zamabhethri e-Lithium-ion ngaphezu kwamabhethri e-lead-acid◎Ukusetshenziswa kwamabhethri e-lithium-ion yesimanje kuletha izinzuzo eziningi amabhethri alula we-lead-acid angeke akwazi ukuziletha.◎Okokuqala, anempilo yesevisi ende kakhulu kunamabhethri e-lead-acid.Ibhethri ye-lithium-ion iyakwazi ukugcina amandla elanga isikhathi esicishe sibe yiminyaka engama-20.◎Inani lemijikelezo yokushaja kanye nokujula kokukhishwa nakho kukhulu ngokuphindwe kaningi kunamabhethri omthofu.◎Ngenxa yezinto ezihlukene ezisetshenziswa ekukhiqizeni, amabhethri e-lithium-ion nawo alula kakhulu kunamabhethri omthofu futhi ahlangene kakhulu.Ngakho-ke, bathatha indawo encane ngesikhathi sokufakwa.◎Amabhethri e-lithium-ion nawo anezindawo zokugcina ezingcono ngokuzikhipha.◎Ngaphezu kwalokho, umuntu akumelwe akhohlwe isici sezemvelo: Ngoba amabhethri omthofu awahambisani neze nemvelo ekukhiqizeni kwawo ngenxa yomthofu osetshenzisiwe.Izibalo Zokhiye Wobuchwepheshe Bamabhethri e-Lithium-ionNgakolunye uhlangothi, kufanele futhi kuphawulwe ukuthi, ngenxa yesikhathi eside sokusetshenziswa kwamabhethri omthofu, kunezifundo ezinengqondo kakhulu zesikhathi eside kunamabhethri e-lithium-ion asemasha kakhulu, ukuze ukusetshenziswa kwawo kanye nezindleko ezihambisana nawo. ingabuye ibalwe kangcono nangokwethembeka.Ngaphezu kwalokho, uhlelo lokuphepha lwamabhethri omthofu wesimanje ngokwengxenye lungcono kakhulu kunalolo lwamabhethri e-lithium-ion.Empeleni, ukukhathazeka mayelana nokukhubazeka okuyingozi kumaseli e-li ion nakho akunasisekelo: Isibonelo, ama-dendrites, okungukuthi amadiphozithi e-lithium akhomba, angakheka ku-anode.Amathuba okuthi lezi bese zicupha izifunda ezimfushane, futhi ngaleyo ndlela ziphinde zibangele ukubaleka kokushisa (ukusabela kwe-exothermic ngesizukulwane sokushisa esinamandla, esizisheshisayo), anikezwa ikakhulukazi kumaseli e-lithium aqukethe izingxenye zeseli zekhwalithi ephansi.Esimweni esibi kakhulu, ukusakazeka kwaleli phutha kumaseli angomakhelwane kungaholela ekuphenduleni kweketanga kanye nomlilo ebhethri.Kodwa-ke, njengoba amakhasimende amaningi esebenzisa amabhethri e-lithium-ion njengamabhethri elanga, imiphumela yokufunda yabakhiqizi abanenani elikhulu lokukhiqiza iphinde iholele ekuthuthukisweni okwengeziwe kobuchwepheshe bokusebenza kwesitoreji kanye nokuphepha okuphezulu kokusebenza kwamabhethri e-lithium-ion kanye nokwehliswa kwezindleko ezengeziwe. .Isimo samanje sokuthuthukiswa kobuchwepheshe bamabhethri e-Li-ion singafingqwa ngezibalo ezilandelayo ezibalulekile:
