Isingeniso:
Amabhethri ayingxenye ebalulekile yamadivayisi amaningi nezinhlelo, kusuka kuma-Smartphones kanye nama-laptops ezimotweni nasemodeni elanga. Ukwazi uhlobo lwebhethri olisebenzisayo lubalulekile ukuphepha, ukugcinwa kanye nezinhloso zokulahla. Izinhlobo ezimbili ezivamile zamabhethriI-Lithium-ion (li-ion)namabhethri e-lead-acid. Uhlobo ngalunye lunezimpawu zalo futhi ludinga ukuphathwa okuhlukile. Kulesi sihloko, sizoxoxa ngokuthi singayisho kanjani uma ibhethri li-lithium noma ukuhola, kanye nomehluko omkhulu phakathi kwalokhu okubili.
Ukubonakala
Enye yezindlela ezilula zokuhlukanisa phakathi kwamabhethri e-lithium nama-hoidi-acid ngokubukeka kwawo komzimba. Amabhethri e-lead-acid ngokuvamile akhulu futhi anisindayo kuneamabhethri e-lithium-ion.Imvamisa zixande noma isikwele ngesimo futhi zinesembozo esivelile se-top ukuze sengeze amanzi. Uma uqhathanisa, amabhethri e-lithium-ion ancanyana, alula, futhi aza ngezimo ezahlukahlukene, kufaka phakathi i-cylindrical ne-prismatic. Abanayo isembozo esinqunyiwe futhi bavame ukuvalelwa epulasitiki.
Amathegi kanye namathegi
Enye indlela yokuthola uhlobo lwebhethri ukubheka amalebula nokumakwa ebhethri uqobo. Amabhethri e-lead-acid avame ukuba namalebula afana nalokhu, futhi angaba nokumaka okubonisa ama-voltage kanye namandla. Ngaphezu kwalokho, amabhethri e-Holive-acid avamisile amalebula axwayisa mayelana nobungozi be-sulfuric acid kanye nesidingo sokuphotha umoya ofanele. Amabhethri e-Lithium-ion, ngakolunye uhlangothi, ajwayele ukufakwa amalebula ngolwazi mayelana nokwakheka kwamakhemikhali, amavolumu, namandla anamandla. Bangase futhi babe nezimpawu ezibonisa ukuhambisana namazinga okuphepha, njenge-Ul (ama-laboratoratories angaphansi) noma i-European Ukuhlola Ukuhlola).
Voltage kanye namandla
I-voltage yebhethri namandla futhi anganikela ngemikhombandlela ngohlobo lwayo. Amabhethri e-lead-acid atholakala ngokuvamile kuma-voltages ama-2, 6, noma ama-12 volts futhi asetshenziswa kakhulu kwizicelo ezidinga okuphezulu kwamanje, njengamabhethri okuqala imoto. Ngakolunye uhlangothi, amabhethri e-lithium-ion, anobunzima obuphakeme wamandla, ngama-voltages asukela kuma-3.7 volts esitokisini esisodwa kuya kwama-48 amaphakethe webhethri asetshenziswa ezimotweni zikagesi noma amasistimu wokugcina amandla.
Izidingo zokulungiswa
Ukuqonda izidingo zokulungiswa kwebhethri kungasiza nokukhomba uhlobo lwayo. Amabhethri e-lead-acid adinga ukulungiswa okujwayelekile, kufaka phakathi amazinga okuhlola ama-electrolyte anamanzi anciphile, ama-terminals ahlanza, kanye nokuqinisekisa umoya omncane ukuze uvikele ukwakhiwa kwegesi ye-hydrogen eqhumayo. Ngokungqubuzanayo,Amabhethri e-Lithium-ionzikhululekile futhi azidingi ukuchelela njalo noma ukuhlanza okubulalayo. Kodwa-ke, badinga ukuvikeleka ekulahlekelweni ngokweqile kanye nokukhipha okujulile ukuvikela ukulimala futhi kuqinisekise isikhathi eside.
Umthelela emvelweni
Umthelela wezemvelo webhethri ungaba ukucatshangelwa okubalulekile lapho unquma uhlobo lwebhethri. Amabhethri e-lead-acid aqukethe ukuhola kanye ne-sulfuric acid, zombili ezingalimaza emvelweni uma zingalawulwa kahle. Ukuhola kuyinsimbi enobuthi esindayo ne-sulfuric acid kuyawohloka futhi kungadala inhlabathi nokungcoliswa kwamanzi uma kungaxazululwa kahle futhi kuchithwe. Amabhethri e-Lithium-Ion abuye alethe izinselelo zezemvelo ngenxa yokukhishwa kwe-lithium nezinye izinsimbi zomhlaba ezingandile, ezingaholela ekubalekeni okushisayo kanye nemililo uma kungavunyelwanga kahle. Ukuqonda umthelela wezemvelo wamabhethri kungakusiza ukuba wenze izinqumo ezinolwazi ngokusetshenziswa kwebhethri nokulahlwa.
Ukulahla nokuphinda usebenzise kabusha
Ukulahlwa okufanelekile kanye nokuvuselelwa kabusha kwamabhethri kubalulekile ukunciphisa umthelela wezemvelo kanye nokuqinisekisa ukuthi izinto ezibalulekile ziyatholakala. Amabhethri e-lead-acid ajwayele ukuvunziwa kabusha ukuze abuyiselwe ukuhola nangopulasitiki, okungasetshenziswa ukwenza amabhethri amasha neminye imikhiqizo. Ukuphinda usebenzise kabusha amabhethri we-lead-acid kusiza ukuvikela ukungcoliswa kokuhola futhi kulondolozwe izinsiza zemvelo.Amabhethri e-Lithium-ionFuthi aqukethe izinto ezibalulekile ezifana ne-lithium, i-cobalt kanye ne-nickel, ezingaphinde zisetshenziswe kabusha futhi zisetshenziswe kabusha kumabhethri amasha. Kodwa-ke, ingqalasizinda eyenziwe kabusha yamabhethri e-lithium-ion isathuthuka, futhi izinqubo ezifanele zokuvuselela kabusha zibalulekile ekunciphiseni ukulimala kwemvelo.
Ukucatshangelwa Kwezokuphepha
Ukuphepha kuyisici esibalulekile lapho usingatha futhi ukhomba amabhethri, ikakhulukazi amabhethri e-lithium-ion, ezaziwa ngokuthi ama-runaway ashisayo futhi abambe umlilo uma elonakaliswa. Ukuqonda izinyathelo zokuphepha zohlobo ngalunye lwebhethri kubalulekile ukuvikela izingozi futhi kuqinisekiswe ukuphathwa okufanele. Amabhethri e-lead-acid angakhipha igesi eqhumayo ye-hydrogen uma edluliselwe ngaphezulu noma emfushane, futhi angenza ukushiswa kwamakhemikhali uma i-electrolyte ihlangana nesikhumba noma ngamehlo. Ukuphepha okufanelekile kokuphepha, njengokusebenzisa imishini yokuzivikela komuntu kanye nokulandela imihlahlandlela yomenzi, kubalulekile lapho usebenza nanoma yiluphi uhlobo lwebhethri.
Ukugcina
Ngokufundwa, ekhomba ukuthi ibhethri yi-lithium noma i-lead-acid idinga ukucatshangelwa kwezinto ezahlukahlukene, kufaka phakathi ukubukeka komzimba, amalebula kanye nezinketho zemvelo, izidingo zemvelo, izinketho zokulahla kabusha kanye nokuhlolwa kokulahla kabusha. Ngokuqonda umehluko phakathi kwama-lithium-ion namabhethri e-lead-acid, abantu nezinhlangano bangenza izinqumo ezinolwazi mayelana nokusetshenziswa kwabo, ukugcinwa kanye nokulahlwa kwabo. Ukukhonjwa okufanele nokuphathwa kwamabhethri kubalulekile ukuphepha, ukuvikela imvelo kanye nokulondolozwa kwezinsizakusebenza. Uma ungabaza ngohlobo lwebhethri, kunconywa ukubonisana nomenzi noma uchwepheshe ofanelekayo ukuze uthole ukuholwa.
Uma unemibuzo noma ungathanda ukufunda okuningi, sicela ungangabazifinyelela kithi.
