Uyafuna ukwenza ibhethri lisebenze?

Impendulo iwukuthi ibhethri idinga ukwenziwa isebenze, kodwa lona akuwona umsebenzi womsebenzisi. Ngavakashela kuleyo mboni. Ezinsukwini zokuqala, amabhethri e-lithium ahamba ngezinqubo ezilandelayo:

I-electrolyte yegobolondo lebhethri ye-lithium ifakwe-perfused-to-seal, ishajwa nge-voltage engaguquki, bese iyakhishwa. Lo mjikelezo uphindaphindiwe izikhathi eziningana. I-electrolyte iyiningi futhi imanzisa i-electrode. Ikhono lokuvula liqinile futhi lihlangabezana nezidingo. Leli khono liyinqubo esebenzayo. Hlola Umthamo webhethri, khetha izinga lokuhlukaniswa komehluko webhethri lebhethri elinemisebenzi ehlukene (umthamo), ukufanisa umthamo, njll. Ibhethri ye-lithium ewumphumela manje isiyasebenza ezandleni zabasebenzisi. Amabhethri e-Ni-Cd kanye ne-Ni-MH nawo angenziwa asebenze ngokuguqulwa kwefekthri. Amanye amabhethri ayasebenza esimweni esivuliwe futhi avalwa ngemva kokwenza kusebenze. Le nqubo ingenziwa kuphela umkhiqizi webhethri.

★Lokho okubizwa ngokuthi ukusebenza kwesibili nakho kungenziwa. Umsebenzisi uzama ukushajwa futhi ashiye ibhethri izikhathi eziningi ngangokunokwenzeka lapho esebenzisa ibhethri elisha okokuqala ngqa.

● Kodwa ngokusho kokuhlola kwami ​​(mayelana namabhethri e-lithium), isikhathi sokugcina amabhethri e-lithium yizinyanga ezingu-1-3. Kuyishajethi ejulile kanye nokucutshungulwa komjikelezo ojulile, futhi isimo sakhona sokuhamba somthamo awekho nhlobo. (Nginesitatimende sokuqinisekisa ukwenza kusebenze ibhethri esigabeni sengxoxo.)

Ingabe kuthatha amahora angu-12 ezimweni ezintathu zokuqala?

Le nkinga ihlobene eduze nenkinga yokusebenzisa ibhethri okukhulunywe ngayo ngenhla. Uma sicabanga ukuthi ibhethri lasembonini line-electrode passivation esandleni somsebenzisi, kuthatha imijikelezo emithathu yokushaja ejulile nokukhipha ukuze ibhethri isebenze. Eqinisweni, inkinga yokushaja okujulile akuwona amahora angu-12 wokungakhokhi. Ngakho-ke esinye isihloko sami esithi “Isikhathi Sokushaja Ibhethri Yefoni Yomakhalekhukhwini” siphendula lo mbuzo.

Impendulo ayikhokhisi amahora angu-12.

Ezinsukwini zakuqala, ngenxa yesinxephezelo sesidingo kanye nenqubo yokushaja ama-drip yamabhethri e-Ni-MH eselula, kungathatha cishe amahora angu-5 ukufinyelela esimweni sokushaja esiphelele esikhundleni samahora angu-12. Izici zokushaja kwamandla kagesi ezingaguquki zamanje neziqhubekayo zamabhethri e-lithium zenza isikhathi sokushaja esijulile sibe ngaphansi kwamahora angu-12.

Isibonelo, kubhethri engu-600ma, setha lamanje ku-0.01C.6mA), isikhathi sokushaja se-1C aseqi emaminithini angu-150, bese usetha yamanje ku-0.001 ° C (0.6mA), futhi isikhathi sokushaja amahora angu-10. Lokhu kungase kube ngenxa yokunemba kwethuluzi. Ayikwazi ukutholwa ngokunembile manje, kodwa umthamo otholwe kusuka ku-0.01 kuya ku-0.001 degrees yi-1.7 mA kuphela, futhi umthamo otholwe ngokushintshanisa amahora angaphezu kuka-7 ungaphansi kuka-3/1000, ongenakho ukubaluleka okungokoqobo.

Ngaphezu kwalokho, zikhona ezinye izindlela zokushaja. Isibonelo, uma indlela yokushaja ishayela yebhethri ye-lithium ifinyelela ku-voltage wokubopha ongu-4.2V, ngeke iphele kusigaba samanje esincane, ngokuvamile imizuzu engu-150 ngemva kokushajwa okugcwele okungu-100%. Omakhalekhukhwini abaningi bashayelwa ama-pulses.

Abanye abantu basebenzisa omakhalekhukhwini babo ukuze bashaje eminyakeni yokuqala, base besebenzisa isihlalo ukushaja ukuze babone ubukhulu obugcwele bomakhalekhukhwini. Le ndlela yokuhlola ayiqaphile.

Okubalulekile Ilambu eliluhlaza elikhishwa ishaja akukona ukuhlola ukushaja kwangempela.

★★Hlola i-voltage lapho ibhethri ye-lithium ishajwa (noma ikhishwe) yonke indlela ngemva kokuthola ukuthi ibhethri ye-lithium ishajwe ngokugcwele.

Inhloso yangempela yesigaba samanje sokwehla kwamandla kagesi ukwehlisa kancane kancane i-voltage eyengeziwe ebangelwa ukushaja kwamandla okumelana nebhethri kwangaphakathi. Uma i-current iphansi njengo-0.01c, njengo-6mA, umkhiqizo wamanje kanye nokumelana kwangaphakathi kwebhethri (ngokuvamile ngaphakathi kwama-millionhm angu-200) kuba ngu-1mV kuphela, futhi i-voltage ngalesi sikhathi ingabhekwa njenge-voltage yebhethri okwamanje.

Okwesibili, i-voltage yereferensi yeselula ayilingani ngempela ne-voltage eyireferensi yokushaja kwesihlalo. Ifoni ephathekayo icabanga ukuthi ibhethri igcwele futhi ishaja isihlalo, kuyilapho isihlalo sicabanga ukuthi ibhethri ayigcwele futhi iyaqhubeka nokushaja.
