Isingeniso:
Amabhethri e-lithiumsesiyingxenye ebalulekile yokuphila kwethu kwansuku zonke, sinikeza amandla yonke into kusukela kuma-smartphones nama-laptops kuya ezimotweni zikagesi nezinhlelo zokugcina amandla. Ukuminyana kwazo okuphezulu, ubude besikhathi sokuphila, kanye nemvelo engasindi kuzenza zibe ukukhetha okudumile kumishini kagesi ephathekayo nezinhlelo zokusebenza zamandla avuselelekayo. Nokho, isici esisodwa esibalulekile sokusebenzisa amabhethri e-lithium isidingo seshaja ehlukile uma kuqhathaniswa nezinye izinhlobo zamabhethri. Kulesi sihloko, sizohlola izizathu zalesi sidingo kanye nokubaluleka kokusebenzisa ishaja ethile yamabhethri e-lithium.
Izizathu:
Amabhethri e-lithiumziwuhlobo lwebhethri elishajekayo elisebenzisa i-lithium ion njengengxenye eyinhloko yokusabela kwayo kwe-electrochemical. Ngokungafani namabhethri endabuko e-lead-acid noma i-nickel-cadmium, amabhethri e-lithium asebenza ngama-voltage aphezulu futhi anezici ezithile zokushaja nokukhipha. Ngenxa yalokho, ukusebenzisa ishaja ejwayelekile eyenzelwe ezinye izinhlobo zamabhethri kungaholela ezinkingeni ezimbalwa kanye nezingozi zokuphepha ezingaba khona.
Esinye sezizathu eziyinhloko zokuthi kungani amabhethri e-lithium adinga ishaja ehlukile ukuzwela kwawo ekushajweni ngokweqile. Ngokungafani nezinye izinhlobo zamabhethri,amabhethri e-lithiumzingalimala noma zibe sengozini yezokuphepha uma zikhokhiswe ngokweqile. Lokhu kungenxa yokwakheka kwamakhemikhali kwamaseli e-lithium-ion, angase angazinzi futhi okungenzeka aholele ekubalekeni okushisayo uma engaphansi kokushaja okunamandla kagesi.
Ngakho-ke, ishaja yebhethri ye-lithium ezinikele yenzelwe ukuqapha nokulawula inqubo yokushaja ukuvimbela ukushajwa ngokweqile nokuqinisekisa ukuphepha kwebhethri.
Ngaphezu kwalokho, amabhethri e-lithium ane-voltage ethize kanye nezidingo zamanje zokushaja, ezihlukile kwezamanye amakhemistri webhethri. Ukusebenzisa ishaja engahlangabezani nalezi zidingo kungase kubangele ukushaja okungasebenzi, ukuncipha kwempilo yebhethri, kanye nokulimala okungaba khona kumaseli ebhethri. Ishaja yebhethri ye-lithium ezinikele iklanyelwe ukuletha amandla kagesi anembile kanye namazinga amanje adingekayo ukuze ishajwe ngokugcwele, iqinisekisa ukuthi ibhethri ishajwe kahle futhi ngokuphephile.
Esinye isici esibalulekile sokushajwa kwebhethri le-lithium isidingo sokulinganisa amaseli ngamanye ngaphakathi kwephakethe lebhethri. Amaphakethe ebhethri le-lithium aqukethe amaseli amaningi axhunywe kuchungechunge nokucushwa okuhambisanayo ukuze kuzuzwe amandla kagesi afiswayo. Phakathi nenqubo yokushaja, kubalulekile ukulinganisa amandla kagesi kanye nesimo sokushajwa kweseli ngalinye ukuze kuvinjelwe ukushajwa ngokweqile noma ukushajwa okungaphansi kwamaseli athile, okungaholela ekonakaleni kokusebenza kanye nezingozi zokuphepha. Ishaja yebhethri ye-lithium ezinikele ihlanganisa ukujikeleza kokulinganisa ukuze kuqinisekiswe ukuthi iseli ngalinye elingaphakathi kwephakethe lebhethri lishajwa futhi lishajwa ngokulinganayo, okwandisa ukusebenza kwakho konke nempilo yebhethri.
Ngaphezu kokucatshangelwa kwezobuchwepheshe, ikhemikhali yamabhethri e-lithium nayo idlala indima ebalulekile esidingweni seshaja ehlukile. Amaseli e-lithium-ion anejika elihlukile lokukhipha ukushaja uma kuqhathaniswa namanye amakhemikhali ebhethri, adinga i-algorithm yokushaja eyinkimbinkimbi ukuze kuthuthukiswe inqubo yokushaja. A ozinikeleibhethri ye-lithiumishaja ifakwe ama-algorithms wokushaja athuthukisiwe kanye nezinhlelo zokuqapha ukuze ivumelane nezici ezithile zamaseli e-lithium-ion, iqinisekisa ukuthi ibhethri ishajwa ngendlela ekhulisa ukusebenza kwayo nokuphila isikhathi eside.
Ukuphepha kokushajwa kwebhethri le-lithium akukwazi ukweqiwa. Amabhethri e-lithium anomthamo omkhulu wamandla futhi athambekele kakhulu ekubalekeni okushisayo nezinye izinkinga zokuphepha uma engashajwa kahle. Ishaja yebhethri ye-lithium ezinikele ihlanganisa izici zokuphepha ezifana nokuvikela ugesi omningi, ukuvikelwa kwe-overcurrent, nokuqapha izinga lokushisa ukuze kuvinjelwe izingozi ezingaba khona phakathi nenqubo yokushaja. Lezi zindlela zokuphepha zibalulekile ekwehliseni ubungozi obuhambisana nokushajwa kwebhethri le-lithium kanye nokuqinisekisa ukuphepha kukonke kwenqubo yokushaja.
Isiphetho
Sengiphetha, izici eziyingqayizivele kanye nekhemikhali yamabhethri e-lithium zenza kudingeke ukuthi kusetshenziswe ishaja ehlukile uma kuqhathaniswa nezinye izinhlobo zamabhethri. Ishaja yebhethri ye-lithium ezinikele iklanyelwe ukubhekana nezidingo ezithile zokushaja, ukucatshangelwa kokuphepha, nezidingo zokuthuthukisa ukusebenza kwamaseli e-lithium-ion. Ngokusebenzisa ishaja ethile eyenzelwe yonaamabhethri e-lithium, abasebenzisi bangaqinisekisa ukushajwa okusebenzayo nokuphephile kwamabhethri abo, ekugcineni bakhulise isikhathi sabo sempilo nokusebenza. Njengoba isidingo samabhethri e-lithium siqhubeka sikhula kuzo zonke izimboni ezihlukahlukene, ukuqonda ukubaluleka kokusebenzisa ishaja ehlukile yamabhethri e-lithium kubalulekile ekukhuthazeni ukusetshenziswa kwebhethri okuphephile nokusebenza kahle.
