Isingeniso：
Amabhethri e-lithiumsezibe yingxenye ebalulekile yempilo yethu yansuku zonke, zinika amandla yonke into kusukela kuma-smartphone nama-laptop kuya ezimotweni zikagesi kanye nezinhlelo zokugcina amandla. Ubuningi bazo bamandla aphezulu, isikhathi eside sokuphila, kanye nokukhanya kwazo kuzenza zibe ukukhetha okuthandwayo kwamadivayisi kagesi aphathekayo kanye nezinhlelo zokusebenza zamandla avuselelekayo. Kodwa-ke, isici 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-lithiumuhlobo lwebhethri eliphinde lishajwe elisebenzisa ama-ion e-lithium njengengxenye eyinhloko yokusabela kwalo 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 eziningana kanye nezingozi zokuphepha ezingaba khona.
Esinye sezizathu eziyinhloko zokuthi kungani amabhethri e-lithium edinga ishaja ehlukile ukuzwela kwawo ekushajeni ngokweqile. Ngokungafani nezinye izinhlobo zamabhethri,amabhethri e-lithiumkungalimala noma kube yingozi yokuphepha uma kushajwa kakhulu. Lokhu kungenxa yokwakheka kwamakhemikhali kwamaseli e-lithium-ion, okungaba okungazinzile futhi okungaholela ekubalekeni kokushisa uma kutholakala ama-voltage amaningi okushaja.
Ngakho-ke, ishaja yebhethri ye-lithium ezinikele yenzelwe ukuqapha nokulawula inqubo yokushaja ukuze kuvinjelwe ukushaja ngokweqile nokuqinisekisa ukuphepha kwebhethri.
Ngaphezu kwalokho, amabhethri e-lithium anezidingo ezithile ze-voltage kanye nezamanje zokushaja, ezihlukile kwezezinye izikhungo ze-chemistry yebhethri. Ukusebenzisa ishaja engahlangabezani nalezi zidingo kungabangela ukushaja okungasebenzi kahle, ukunciphisa isikhathi sebhethri, kanye nomonakalo ongaba khona kumaseli ebhethri. Ishaja yebhethri ye-lithium ezinikele yenzelwe ukuletha amazinga e-voltage kanye nezamanje afanele ukushaja kahle, ukuqinisekisa ukuthi ibhethri lishajwa kahle nangokuphephile.
Esinye isici esibalulekile sokushaja ibhethri le-lithium isidingo sokulinganisa amaseli ngamanye ngaphakathi kwephakethe lebhethri. Amaphakethe ebhethri le-lithium aqukethe amaseli amaningi axhunywe ngokulandelana kanye nokucushwa okuhambisanayo ukuze kufezwe i-voltage kanye nomthamo ofunekayo. Ngesikhathi senqubo yokushaja, kubalulekile ukulinganisela i-voltage kanye nesimo sokushaja seseli ngalinye ukuze kuvinjelwe ukushaja ngokweqile noma ukushaja okunganele kwamaseli athile, okungaholela ekwehleni kokusebenza kanye nezingozi zokuphepha. Ishaja yebhethri le-lithium ezinikele ifaka i-balancing circuitry ukuqinisekisa ukuthi iseli ngalinye ngaphakathi kwephakethe lebhethri liyashaja futhi likhishwa ngokulinganayo, okwandisa ukusebenza kanye nokuphila kwebhethri.
Ngaphezu kokucatshangelwa kobuchwepheshe, i-chemistry yamabhethri e-lithium nayo idlala indima ebalulekile ekudingeni ishaja ehlukile. Amaseli e-lithium-ion ane-curve ehlukile yokukhipha ishaja uma kuqhathaniswa namanye amakhemikhali ebhethri, adinga i-algorithm yokushaja eyinkimbinkimbi kakhulu ukuze kuthuthukiswe inqubo yokushaja.ibhethri le-lithiumIshaja ifakwe ama-algorithms okushaja athuthukile kanye nezinhlelo zokuqapha ukuze zivumelane nezici ezithile zamaseli e-lithium-ion, okuqinisekisa ukuthi ibhethri lishajwa ngendlela ekhulisa ukusebenza kwalo kanye nobude balo.
Ukuphepha kokushaja ibhethri le-lithium akukwazi ukweqiswa. Amabhethri e-lithium anomthamo omkhulu wamandla futhi athambekele kakhulu ekubalekeni kokushisa kanye nezinye izinkinga zokuphepha uma engashajwa kahle. Ishaja yebhethri le-lithium ezinikele ifaka izici zokuphepha ezifana nokuvikelwa kwamandla aphezulu, ukuvikelwa kwamandla aphezulu, kanye nokuqapha izinga lokushisa ukuvimbela izingozi ezingaba khona ngesikhathi senqubo yokushaja. Lezi zindlela zokuphepha zibalulekile ekunciphiseni izingozi ezihlobene nokushaja ibhethri le-lithium nokuqinisekisa ukuphepha okuphelele kwenqubo yokushaja.
Isiphetho
Ekuphetheni, izici ezihlukile kanye nekhemikhali yamabhethri e-lithium kudinga ukusetshenziswa kweshaja ehlukile uma kuqhathaniswa nezinye izinhlobo zamabhethri. Ishaja yebhethri ye-lithium ezinikele yenzelwe ukubhekana nezidingo ezithile zokushaja, izinto ezicatshangelwayo zokuphepha, kanye nezidingo zokuthuthukisa ukusebenza kwamaseli e-lithium-ion. Ngokusebenzisa ishaja ethile eyenzelweamabhethri e-lithium, abasebenzisi bangaqinisekisa ukuthi amabhethri abo ayashajwa ngendlela ephumelelayo nephephile, ekugcineni bandise isikhathi sabo sokuphila kanye nokusebenza. Njengoba isidingo samabhethri e-lithium siqhubeka nokukhula kuzo zonke izimboni ezahlukene, ukuqonda ukubaluleka kokusebenzisa ishaja ehlukile yamabhethri e-lithium kubalulekile ekukhuthazeni ukusetshenziswa kwebhethri okuphephile nokusebenzayo.
