Passivation in Lithium Amabhethri
I-passivation kumabhethri e-lithium, ikakhulukazi lawo asebenzisa i-lithium thionyl chloride (I-LiSOCl2) ikhemistri, ibhekisela kwinto evamile lapho ifilimu elincanyana lakha phezu kwe-lithium anode. Le filimu yakhiwe ikakhulukazi i-lithium chloride (LiCl), i-byproduct yokusabela kwamakhemikhali okuyinhloko ngaphakathi kweseli. Yize lesi sendlalelo sokunciphisa singathinta ukusebenza kwebhethri, ikakhulukazi ngemva kwesikhathi eside sokungasebenzi, siphinde sidlale indima ebalulekile ekuthuthukiseni impilo yeshalofu yebhethri nokuphepha.
Ukwakhiwa Kwesendlalelo Se-Passivation
Kumabhethri e-lithium thionyl chloride, ukudlula kwenzeka ngokwemvelo ngenxa yokusabela phakathi kwe-lithium anode ne-thionyl chloride (SOCl2) electrolyte. Lokhu kusabela kukhiqiza i-lithium chloride (LiCl) kanye ne-sulphur dioxide (SO2) njengemikhiqizo ekhiqizwayo. I-lithium chloride kancane kancane yenza ungqimba oluncane oluqinile ebusweni be-lithium anode. Lesi singqimba sisebenza njengesivikelo sikagesi, sivimbela ukugeleza kwama-ion phakathi kwe-anode ne-cathode.
Izinzuzo Passivation
Isendlalelo se-passivation asiyona ingozi ngokuphelele. Inzuzo yayo eyinhloko ukuthuthukisa impilo yeshalofu yebhethri. Ngokukhawulela izinga lokuzikhulula kwebhethri, isendlalelo sokudlula siqinisekisa ukuthi ibhethri igcina ukushajwa kwayo ngesikhathi esinwetshiwe sokugcina, okwenza amabhethri e-LiSOCl2 alungele izinhlelo zokusebenza lapho ukuthembeka kwesikhathi eside ngaphandle kokunakekelwa kubalulekile, njengasezimeni eziphuthumayo namandla ayisipele. izimpahla, amasosha, kanye nemishini yezokwelapha.
Ngaphezu kwalokho, isendlalelo se-passivation sinomthelela ekuphepheni okuphelele kwebhethri. Ivimbela ukusabela okweqile phakathi kwe-anode ne-electrolyte, okungaholela ekushiseni ngokweqile, ekuqhumeni, noma ngisho nokuqhuma ezimeni ezimbi kakhulu.
Izinselelo ze-Passivation
Ngaphandle kwezinzuzo zako, ukwehlisa amandla kubangela izinselele ezinkulu, ikakhulukazi uma ibhethri libuyiselwa kusevisi ngemva kwesikhathi eside lingasebenzi. Izakhiwo zokuvikela ze-passivation layer zingaholela ekwandeni kokumelana kwangaphakathi, okungase kubangele:
● I-voltage yokuqala eyehlisiwe (ukubambezeleka kwe-voltage)
●Umthamo usuwonke unciphe
●Isikhathi sokuphendula esinensayo
Le miphumela ingaba yinkinga kumadivayisi adinga amandla aphezulu ngokushesha lapho ivuliwe, njengezilandeleli ze-GPS, izithumeli zendawo eziphuthumayo, nezinye izisetshenziswa zezokwelapha.
Ukususa noma Ukunciphisa Imithelela Yokudlula
1. Ukusebenzisa Umthwalo: Indlela eyodwa evamile yokunciphisa imithelela yokudlula ihlanganisa ukufaka umthamo kagesi omaphakathi ebhethrini. Lo mthwalo usiza 'ekuphuleni' isendlalelo sokudlula, ngokuyisisekelo sivumele ama-ion ukuthi aqale ukugeleza ngokukhululeka phakathi kwama-electrode. Le ndlela ivame ukusetshenziswa lapho amadivaysi ekhishwa endaweni yokugcina futhi kudingeka ukuthi asebenze ngokushesha.
2. Ukushaja i-Pulse: Ezimweni ezinzima kakhulu, indlela ebizwa ngokuthi ukushaja ishayela ingasetshenziswa. Lokhu kubandakanya ukusebenzisa uchungechunge lwama-pulses amafushane, amanje aphezulu kubhethri ukuze kuphazamise ungqimba lwe-passivation kakhudlwana. Le ndlela ingasebenza kahle kodwa kufanele ilawulwe ngokucophelela ukugwema ukulimaza ibhethri.
3. Isimo Sebhethri: Amanye amadivaysi ahlanganisa inqubo yokumisa efaka umthwalo ebhethrini ngesikhathi sokulondoloza. Lesi silinganiso sokuvimbela sisiza ekunciphiseni ukujiya kongqimba lwe-passivation olwakhayo, ukuqinisekisa ukuthi ibhethri lihlala lilungele ukusetshenziswa ngaphandle kokuwohloka okuphawulekayo kokusebenza.
4. Izimo Zokugcina Ezilawulwayo: Ukugcina amabhethri ngaphansi kwezimo zemvelo ezilawulwayo (izinga lokushisa elilungile kanye nomswakama) nakho kunganciphisa izinga lokwakheka kongqimba lwe-passivation. Amazinga okushisa apholile anganciphisa ukusebenza kwamakhemikhali okuhilelekile ku-passivation.
5. Izithasiselo Zekhemikhali: Abanye abakhiqizi bebhethri bengeza izinhlanganisela zamakhemikhali ku-electrolyte ezingakhawulela ukukhula noma ukuzinza kwesendlalelo sokudlula. Lezi zengezo zenzelwe ukugcina ukumelana kwangaphakathi kumazinga alawulekayo ngaphandle kokuphazamisa ukuphepha noma impilo yeshalofu yebhethri.
Sengiphetha, nakuba i-passivation ekuqaleni ingabonakala njengento embi kumabhethri e-lithium thionyl chloride, inkemba esika nhlangothi zombili ephinde inikeze izinzuzo ezibalulekile. Ukuqonda imvelo ye-passivation, imithelela yako, kanye nezindlela zokunciphisa le miphumela kubalulekile ekwandiseni ukusebenza kwalawa mabhethri ezinhlelweni zokusebenza. Amasu afana nokufaka umthwalo, ukushaja ukushaya kwenhliziyo, kanye nesimo sebhethri kubalulekile ekulawuleni ukudlula, ikakhulukazi ezinhlelweni ezibucayi nezithembeke kakhulu. Njengoba ubuchwepheshe buthuthuka, ukuthuthukiswa okuqhubekayo kukhemistri yebhethri nezinhlelo zokuphatha kulindeleke ukuthi kuthuthukise ukuphathwa kwe-passivation, ngaleyo ndlela kwandise ukusebenza nokusebenza kahle kwamabhethri asekelwe e-lithium.
