Ungalungisa kanjani ibhethri le-lithium nge-voltage kodwa akukho okwamanje?

Lapho sihlangana a ibhethri le-lithium lokho kukhombisa i-voltage kepha akukho okwamanje, Kuyisimo esidinga ukuqonda okuningiliziwe kokusebenza kwangaphakathi kwebhethri kanye nezinkinga ezingenzeka. Ku-salperson, Kungabonakala sengathi ibhethri linamandla kodwa akukho okwamanje, Kepha empeleni, Lokhu kukhombisa ukuthi ukumelana kwangaphakathi kwebhethri kukhuphuke ngezinga elithile, cishe ifinyelela isimo esivulekile, okuholele endaweni eseduze ye-zero.

Uma sibheka ibhethri njengomthombo wamandla kagesi ngokumelana kwangaphakathi okukhulu kakhulu, Lapho kufakwa umthwalo, Ukugeleza kwamanje kudlula cishe akunakudelwa. Nokho, Lapho kulinganiswa nge-voltmeter ebangeni le-voltage, I-voltmeter ngokwayo inokumelana kwangaphakathi okuphezulu kakhulu. Naphezu kwe-loop ye-minuscule yamanje, kwanele ukukhiqiza ukwehla kwamandla kagesi, Ngaleyo ndlela kukhombisa ukufundwa kwamandla kagesi ku-voltmeter.

Kubalulekile ukuqaphela ukuthi wonke amabhethri anesikhathi esichaziwe sokuphila. Lapho ibhethri lifinyelela ekugcineni kwempilo yalo ewusizo, Kuba ukungalungiseki. Njengoba nje zonke izidalwa eziphilayo zigcina zifa, amabhethri nawo aphelelwe yisikhathi lapho engasakwazi ukusebenza ngempumelelo. Kulesi sigaba, Ukumelana kwangaphakathi kwebhethri kuba phezulu kakhulu, ukuyinikela ngaphandle kwenani lokulungisa. Okuwukuphela kwezinketho ezisele kungaba ukuphindaphindeka kabusha noma ukulahlwa okuqondile.

Ngokwesibonelo, amabhethri e-tithiyumu e-ternary ngokuvamile anomjikelezo wokukhishwa kwemali esukela 500 kwa- 1000 Izikhathi, Ngenkathi amabhethri we-lithium iron phosphate angafinyelela kuze kube 2000 Izikhathi. Lapho ibhethri selifinyelele kwinombolo ebekiwe yemijikelezo yokusebenzisa, Ifike ngokuphumelelayo ekugcineni kwempilo yayo yenkonzo futhi ayinakho okukhona.

Amabhethri e-Lithium asebenza ngokususelwa ekuhambeni okuphindaphindiwe kwama-lithium ion phakathi kwama-electrodes amahle nengalungile ngesikhathi sokushaja kanye nezinqubo zokukhipha amandla. Ngesikhathi sokushaja, I-Lithium ion defach kusuka ku-electrode plate ye-electrode futhi yehle ku-electrode engemihle nge-electrolyte. Ngokuqondile, ngesikhathi sokudilika, ukunyakaza kubuyiselwa emuva. Ubukhulu besikhathi samanje buxhomeke kwijubane lapho le mithium ion ihambisa khona.

Uma i-electrolyte ivuza noma yomile phezulu, Kuyafana nomfula olahlekelwa amanzi awo, Ukuvimbela ukunyakaza okubushelelezi kwe-lithium ions. Lokhu kuholela ekwehlisweni okukhulu ngejubane lokuvalwa kwama-lithium ions, okwenza ukwehla okukhulu ngejubane lokukhokhisa le ibhethri le-lithium futhi kuholele kumanje. Ngokungafani namabhethri e-lead-acid, Amabhethri e-Lithium njengamanje awanayo inketho yokungeza i-electrolyte ngokuzimela.

Ngokuhamba kwemijikelezo eminingi yokukhipha, Endleleni lapho kuhamba khona ama-lithium ions, Ukuqongelelwa kwensalela yemfucumfucu kwenzeka. Lokhu kufana nokuvalwa kwenzeke emithanjeni yegazi lomuntu ngenxa yezici ezinjenge-cholesterol njengeNkathi Yodwa. Izinsalela ezinjalo ziyehlisa ukunyakaza kwe-ion, okuholela ekunciphiseni okuphelele kwesindla sebhethri. Endabeni yamabhethri anamandla, Lapho umthamo wehla 80% umthamo olinganiselwe, abasalungele ukusetshenziswa okuqhubekayo.

Nokho, Akuwona wonke amacala a ibhethri le-lithium ekhombisa i-voltage kepha akukho njengamanje angenathemba. Izingqinamba ezihlobene nemibuthano ye-peripheral noma yokuvikela ngokuvamile zingabhekelwa phambili. Ekuxhumeni kwamabhethri e-lithium, okuvame ukwenziwa ngezinsimbi ezinokuvuka okuhle, ukuxhumana nomoya noma ukuvezwa kuma-acid athile nezisekelo ngesikhathi sokusetshenziswa kungaholela ekugcekeni nase-oxidation, kwakha ama-oxides amhlophe noma ezinye izinto ngokusebenza kabi. Lezi zinto zidala ukumelana okukhulu kumaphoyinti okuxhuma, enikeza ukubukeka kokuba namandla kagesi kepha akukho okwamanje. Ezimweni ezinjalo, ukuhlanza noma ukufaka esikhundleni lokhu kuxhumana noma ama-electrodes ukunciphisa ukumelana nokuxhumana kungavumela ibhethri le-lithium ukusebenza kahle futhi.

Ngaphezu kwalokho, amabhethri e-lithium, Ngenxa ye-voltage yabo ephansi ye-monomer futhi yamanje, kuvame ukudinga amaseli amaningi axhumeke ngokufana nochungechunge ukwakha iyunithi. Uma umthamo weyunithi yonke uncipha, Kungabizwa ngokuthi yi-monomer ebanzi noma ukuxhumana kabi okuvela ekutholeni i-sunoptimal soldering ngesikhathi soMhlangano. Ukuhlonza nokulungisa inkinga nge-monomer ehambisanayo kungaxazulula inkinga.

Ngokungafani namabhethri e-lead-acid, Amabhethri e-Lithium azwela kakhulu futhi ajwayele ukudinga amabhodi okuvikela. Uma amabhodi okuvikela ukungasebenzi kahle, kungakhombisa ngokungafanele amandla okuncipha. Ukushintsha iBhodi Lokuvikela Elinephutha lingabuyisela ukusebenza okujwayelekile kwebhethri.

Kunesimo futhi lapho ibhethri selingenzi lutho ngesikhathi eseluliwe, okwenza ukuthi i-voltage ilahle kakhulu kangangokuba iBhodi Lokuvikela lehluleka ukusebenza kahle. Ezimweni ezinjalo, Isusa iBhodi Lokuvikela futhi ishaja ibhethri ngokuzimela isikhashana ukukhulisa amavolushi, kulandelwa ukubuyisela kabusha ibhodi lokuvikela, ingavumela ibhethri ukuthi liqale ukusebenza okujwayelekile.

Ekuphetheni, Lapho usebenza nge ibhethri le-lithium lokho kuveza ama-voltage kepha akukho okwamanje, Ukuhlolwa okuphelele kwezici ezahlukahlukene ezifana nesikhathi sebhethri, Isimo se-electrolyte, Ubuqotho be-PRENCE, futhi isimo sesifunda sokuvikela siyadingeka. Kuya ngesizathu esithile esikhonjwe, Ukulungiswa okufanele noma izindlela zokulungisa zingathathwa. Nokho, Kubalulekile ukusondela ekuxazululeni ibhethri ngokuqapha nokulandela imihlahlandlela yezokuphepha ukugwema izingozi ezingaba khona.
