Isingeniso:
Amabhethri ayingxenye ebalulekile yamadivayisi nezinhlelo eziningi, kusukela kuma-smartphones namakhompyutha aphathekayo kuya ezimotweni kanye nesitoreji selanga. Ukwazi uhlobo lwebhethri olisebenzisayo kubalulekile ngezinhloso zokuphepha, ukunakekelwa kanye nokulahla. Izinhlobo ezimbili ezijwayelekile zamabhethri ziyii-lithium-ion (Li-ion)namabhethri e-lead-acid. Uhlobo ngalunye lunezici zalo futhi ludinga ukuphathwa okuhlukile. Kulesi sihloko, sizoxoxa ngokuthi singasho kanjani ukuthi ibhethri iyi-lithium noma i-lead, kanye nomehluko omkhulu phakathi kwakho kokubili.
Ukubukeka
Enye yezindlela ezilula zokuhlukanisa phakathi kwebhethri le-lithium nele-lead-acid ukubukeka kwawo ngokomzimba. Amabhethri e-lead-acid ngokuvamile makhulu futhi asindayo kunawoamabhethri e-lithium-ion.Zivamise ukuba nonxande noma isikwele ngesimo futhi zinesivalo esikhipha umoya esiyingqayizivele ngaphezulu ukuze kungezwe amanzi. Uma kuqhathaniswa, amabhethri e-lithium-ion ngokuvamile mancane, alula, futhi eza ngezinhlobonhlobo zomumo, okuhlanganisa i-cylindrical ne-prismatic. Azinawo amakhava aphuma umoya futhi ngokuvamile avalelwe ebhokisini lepulasitiki.
Omaka namathegi
Enye indlela yokubona uhlobo lwebhethri ukuhlola amalebula nezimpawu ebhethri ngokwayo. Amabhethri aneasidi yomthofu avame ukuba namalebula afana nalawa, futhi angase abe nezimpawu ezibonisa amandla kagesi namandla. Ukwengeza, amabhethri aneasidi yomthofu avame ukuba namalebula ayisixwayiso ngezingozi ze- sulfuric acid kanye nesidingo sokungena komoya ngendlela efanele. Ngakolunye uhlangothi, amabhethri e-lithium-ion abhalwe ngolwazi mayelana nokwakheka kwamakhemikhali, amandla kagesi, namandla. Bangase futhi babe nezimpawu ezibonisa ukuthobela izindinganiso zokuphepha, njenge-UL (Underwriters Laboratories) noma i-CE (European Conformity Assessment).
Amandla kagesi namandla
Amandla kagesi ebhethri namandla kunganikeza imikhondo ngohlobo lwayo. Amabhethri e-lead-acid ngokuvamile atholakala ngamavolthi angu-2, 6, noma 12 volts futhi avame ukusetshenziswa ezinhlelweni ezidinga ukuphuma okuphezulu kwamanje, njengamabhethri okuqalisa imoto. Amabhethri e-lithium-ion, ngakolunye uhlangothi, anomthamo omkhulu wamandla, nama-voltage asukela ku-3.7 volts ngeseli eyodwa kuya ku-48 volts noma ngaphezulu kumaphakethe amakhulu ebhethri asetshenziswa ezimotweni zikagesi noma izinhlelo zokugcina amandla.
Izidingo zesondlo
Ukuqonda izidingo zokunakekelwa kwebhethri kungasiza futhi ukukhomba uhlobo lwayo. Amabhethri aneasidi yomthofu adinga ukunakekelwa okuvamile, okuhlanganisa ukuhlola nokugcwalisa amazinga e-electrolyte ngamanzi acwengekile, amatheminali okuhlanza, nokuqinisekisa ukungena komoya okufanele ukuze kuvinjelwe ukwakheka kwegesi ye-hydrogen eqhumayo. Ngokungqubuzanayo,amabhethri e-lithium-ionazinakunakekelwa futhi azidingi ukuchelela njalo noma ukuhlanzwa kwetheminali. Kodwa-ke, adinga ukuvikelwa ekushajweni ngokweqile nasekukhishweni okujulile ukuze kuvinjwe umonakalo futhi kuqinisekiswe ukuphila isikhathi eside.
Umthelela endaweni
Umthelela wendawo webhethri ungaba into esemqoka uma kunqunywa uhlobo lwebhethri. Amabhethri aneasidi yomthofu aqukethe i-lead ne-sulfuric acid, kokubili okungaba yingozi endaweni ezungezile uma kungaphathwa kahle. Umthofu uyinsimbi enzima enobuthi futhi i-sulfuric acid iyagqwala futhi ingabangela ukungcoliswa komhlabathi namanzi uma ingaphathwa kahle futhi ilahlwa. Amabhethri e-lithium-ion aphinde alethe izinselelo zemvelo ngenxa yokukhishwa kwe-lithium nezinye izinsimbi zomhlaba eziyivelakancane, ezingaholela nasekubalekeni okushisayo nemililo uma ingavuselelwa kahle. Ukuqonda umthelela wemvelo wamabhethri kungakusiza wenze izinqumo ezinolwazi mayelana nokusetshenziswa nokulahlwa kwebhethri.
Ukulahlwa nokugaywa kabusha
Ukulahlwa ngendlela efanele kanye nokugaywa kabusha kwamabhethri kubalulekile ukuze kuncishiswe umthelela wendawo kanye nokuqinisekisa ukuthi izinto ezibalulekile ziyatholwa. Amabhethri aneasidi yomthofu avame ukugaywa kabusha ukuze kubuyiselwe umthofu nepulasitiki, engasetshenziswa ukwenza amabhethri amasha neminye imikhiqizo. Ukugaywa kabusha kwamabhethri e-lead-acid kusiza ukuvimbela ukungcoliswa komthofu futhi konge izinsiza zemvelo.Amabhethri e-Lithium-ionfuthi iqukethe izinto ezibalulekile ezifana ne-lithium, i-cobalt ne-nickel, engagaywa kabusha futhi isetshenziswe kabusha kumabhethri amasha. Kodwa-ke, ingqalasizinda yokugaywa kabusha kwamabhethri e-lithium-ion isathuthuka, futhi izinqubo ezifanele zokugaywa kabusha zibalulekile ukuze kuncishiswe ukulimala kwemvelo.
Ukucatshangelwa kwezokuphepha
Ukuphepha kuyisici esibalulekile lapho uphatha futhi ukhomba amabhethri, ikakhulukazi amabhethri e-lithium-ion, aziwa ngokubaleka ngokushisayo futhi abambe umlilo uma onakalisiwe noma eshajwe ngokungafanele. Ukuqonda izinyathelo zokuphepha zohlobo ngalunye lwebhethri kubalulekile ukuvimbela izingozi nokuqinisekisa ukuphathwa ngendlela efanele. Amabhethri aneasidi yomthofu angakhulula igesi ye-hydrogen eqhumayo uma eshajwe ngokweqile noma esebenza isikhathi esifushane, futhi angabangela ukusha kwamakhemikhali uma i-electrolyte ihlangana nesikhumba noma amehlo. Izinyathelo zokuphepha ezifanele, ezifana nokusebenzisa okokuvikela kanye nokulandela imihlahlandlela yomkhiqizi, kubalulekile uma usebenza nanoma yiluphi uhlobo lwebhethri.
Isiphetho
Kafushane, ukukhomba ukuthi ibhethri liyi-lithium noma i-lead-acid kudinga ukucatshangelwa kwezinto ezihlukahlukene, okuhlanganisa ukubukeka komzimba, amalebula nezimpawu, amandla kagesi namandla, izidingo zokunakekelwa, umthelela wendawo, izinketho zokulahlwa nokuvuselela kabusha, nokucatshangelwa kokuphepha. Ngokuqonda umehluko phakathi kwamabhethri e-lithium-ion namabhethri e-lead-acid, abantu ngabanye nezinhlangano bangenza izinqumo ezinolwazi mayelana nokusetshenziswa kwabo, ukugcinwa, nokulahlwa kwabo. Ukuhlonzwa ngendlela efanele kanye nokuphathwa kwamabhethri kubalulekile ekuphepheni, ekuvikelweni kwemvelo kanye nokongiwa kwezinsiza. Uma ungabaza ngohlobo lwebhethri, kuyanconywa ukuthi uxhumane nomkhiqizi noma uchwepheshe oqeqeshiwe ukuze uthole isiqondiso.
Uma unemibuzo noma ungathanda ukufunda okwengeziwe, sicela ungangabazifinyelela kithi.
