Yintoni iPasivation yeLiSoCl2 ibhetri? Uyisusa njani?

Ukugqithiswa kwiibhetri zeLithium

Ukugqithiswa kwiibhetri ze-lithium, ngakumbi ezo zisebenzisa i-lithium thionyl chloride (LiSOCl2) i-chemistry, ibhekisela kwinto eqhelekileyo apho ifilimu encinci yenza i-lithium anode. Le filimu iqulunqwe ikakhulu yi-lithium chloride (LiCl), imveliso yempendulo yeekhemikhali eziphambili ngaphakathi kweseli. Ngelixa lo maleko wokunciphisa unokuchaphazela ukusebenza kwebhetri, ngakumbi emva kwexesha elide lokungasebenzi, ukwadlala indima ebalulekileyo ekwandiseni ubomi beshelufu yebhetri kunye nokhuseleko.

Ukuqulunqwa koMaleko wePassivation

Kwiibhetri ze-lithium thionyl chloride, ukugqithisa kwenzeka ngokwemvelo ngenxa yokusabela phakathi kwe-lithium anode kunye ne-thionyl chloride (SOCl2) electrolyte. Le mpendulo ivelisa i-lithium chloride (LiCl) kunye ne-sulphur dioxide (SO2) njengemveliso. I-lithium chloride ngokuthe ngcembe yenza umaleko omncinci, oqinileyo kumphezulu we-lithium anode. Olu luhlu lusebenza njenge-insulator yombane, luthintela ukuhamba kweeyoni phakathi kwe-anode kunye ne-cathode.

Iinzuzo zePasivation

I-passivation layer ayinabungozi ngokupheleleyo. Olona ncedo lwayo luphambili kukuphucula ubomi beshelufu yebhetri. Ngokunciphisa izinga lokuzikhupha kwebhetri, umaleko wokudlula uqinisekisa ukuba ibhetri igcina intlawulo yayo ngexesha elongeziweyo lokugcina, okwenza iibhetri zeLiSOCl2 zilungele usetyenziso apho ukuthembeka kwexesha elide ngaphandle kokugcinwa kubalulekile, njengakwimeko kaxakeka kunye namandla okugcina. izixhobo, zomkhosi, kunye nezixhobo zonyango.

Ngaphezu koko, i-passivation layer inegalelo kukhuseleko olupheleleyo lwebhetri. Ikhusela ukuphendula okugqithisileyo phakathi kwe-anode kunye ne-electrolyte, enokukhokelela ekugqithiseni, ukugqabhuka, okanye ukuqhuma kwiimeko ezinzima.

Imiceli mngeni yePasivation

Ngaphandle kwezibonelelo zayo, i-passivation ibeka imingeni ebalulekileyo, ngakumbi xa ibhetri ibuyiselwa kwinkonzo emva kwexesha elide lokungasebenzi. Iipropathi ezikhuselayo zomaleko we-passivation zingakhokelela ekwandeni kokuchasana kwangaphakathi, okunokuthi kubangele:
● Umbane wokuqala ocuthiweyo (ukulibaziseka kombane)
● Ukuhla kwamandla ewonke
● Ixesha lokuphendula elicothayo

Ezi ziphumo zinokuba yingxaki kwizixhobo ezifuna amandla aphezulu ngokukhawuleza xa zisebenza, ezinje nge-GPS trackers, abathumeli bendawo kaxakeka, kunye nezinye izixhobo zonyango.

Ukususa okanye ukuNcitshiswa kweziphumo zePassivation

1. Ukufaka uMthwalo: Enye indlela eqhelekileyo yokunciphisa iimpembelelo zokudlula ibandakanya ukufaka umthamo wombane ophakathi kwibhetri. Lo mthwalo unceda 'ukwaphula' umaleko wokudlula, ngokuyimfuneko uvumela ii-ion ukuba ziqalise ukuhamba ngokukhululekileyo phakathi kwee-electrode. Le ndlela isetyenziswa rhoqo xa izixhobo zikhutshwa kwindawo yokugcina kwaye kufuneka zenze ngokukhawuleza.

2. Ukutshaja iPulse: Kwiimeko ezinzima ngakumbi, indlela ebizwa ngokuba yi-pulse charging ingasetyenziswa. Oku kubandakanya ukufaka uthotho lwee-pulses ezimfutshane, eziphezulu-yangoku kwibhetri ukuphazamisa i-passivation layer ngakumbi. Le ndlela inokusebenza kodwa kufuneka ilawulwe ngononophelo ukuthintela ukonakalisa ibhetri.

3. Ubume bebhetri: Ezinye izixhobo zibandakanya inkqubo yokubeka imeko ethi ngamaxesha athile ifake umthwalo kwibhetri ngexesha logcino. Lo mlinganiso wothintelo unceda ukunciphisa ubukhulu bomaleko wokudlula owenzekayo, ukuqinisekisa ukuba ibhetri ihlala ikulungele ukusetyenziswa ngaphandle kokuthotywa okubalulekileyo kokusebenza.

4. IiMeko zokuGcina eziLawulwayo: Ukugcina iibhetri phantsi kweemeko ezilawulwayo zokusingqongileyo (ubushushu obuphezulu kunye nokufuma) kunokunciphisa izinga lokubunjwa kwe-passivation layer. Ubushushu obupholileyo bunokucothisa ukusabela kweekhemikhali ezibandakanyekayo kwi-passivation.

5. Izongezo zeMichiza: Abanye abavelisi bebhetri bongeza iikhompawundi zekhemikhali kwi-electrolyte enokunciphisa ukukhula okanye ukuzinza kwe-passivation layer. Ezi zongezo zenzelwe ukugcina ukuchasana kwangaphakathi kumanqanaba alawulekayo ngaphandle kokuphazamisa ukhuseleko okanye ubomi beshelufu yebhetri.

Ukuqukumbela, ngelixa i-passivation inokubonakala ngathi yinto engalunganga kwiibhetri ze-lithium thionyl chloride, likrele elintlangothi-mbini elikwabonelela ngeenzuzo ezibalulekileyo. Ukuqonda ubume be-passivation, iziphumo zayo, kunye neendlela zokunciphisa ezi ziphumo kubalulekile ekwandiseni ukusebenza kwezi bhetri kwizicelo ezibonakalayo. Ubuchwephesha obufana nokufaka umthwalo, ukutshaja i-pulse, kunye ne-betri conditioning ibalulekile ekulawuleni i-passivation, ngakumbi kwizicelo ezibalulekileyo kunye nokuthembeka okuphezulu. Njengoko iteknoloji ihambela phambili, uphuculo olongezelelweyo kwikhemistri yebhetri kunye neenkqubo zolawulo kulindeleke ukuba ziphucule ukuphathwa kwe-passivation, ngaloo ndlela kwandiswa ukusebenza kunye nokusebenza kakuhle kweebhetri ezise-lithium.
