Emphakathini wanamuhla, ukuntuleka kwamandla, ukungcoliswa kwemvelo kanye nezinye izindaba kuye kwaphakamisa izindaba ezibalulekile esintwini.Abakhiqizi bebhethri abahlukahlukene baye bacwaninga ngenkuthalo futhi bathuthukisa izinhlobo ezahlukahlukene zamabhethri, ikakhulukazi amabhethri e-lithium-ion amandla e-lithium-ion njengommeleli othuthukisiwe wokuxazulula le nkinga.Ibhodlela ekusetshenzisweni nasekuthuthukisweni kwamabhethri e-lithium-ion anamandla e-lithium ukuthi ibhethri elilodwa kuphakethe lebhethri liyahluleka ngesikhathi sohlelo lokusebenza oluhlanganisiwe, okuholela ekwehleni kokusebenza okuphelele kwephakethe lebhethri kanye nokusetshenziswa kwebhethri elingaphezu komkhawulo. .
I-Cordless Hammer Drill engu-20mmnjengoba into esebenzayo yebhethri ibizwa ngokuthi ibhethri ye-lithium ion, ehlukaniswe ibhethri ye-lithium ion eyinhloko kanye nebhethri yesibili ye-lithium ion.
Ibhethri elingafaka futhi likhiphe ama-ion e-lithium ngedatha yekhabhoni lingangena esikhundleni se-lithium emsulwa njenge-electrode engeyinhle, inhlanganisela ye-lithium ingasetshenziswa njenge-electrode ephozithivu, kanti i-electrolyte exubile ingasetshenziswa njenge-electrolyte.
Idatha ye-electrode ephozithivu yebhethri ye-lithium ion ngokuvamile yakhiwa izinhlanganisela ezisebenzayo ze-lithium, kuyilapho i-electrode eyinegethivu iyikhabhoni enesakhiwo samangqamuzana esikhethekile.Ingxenye ebalulekile evamile yedatha enhle yi-LiCoO2.Lapho ishaja, amandla kagesi ezigxobo zebhethri ezisenyakatho naseningizimu aphoqa inhlanganisela ku-electrode ephozithivu ukuthi ikhiphe ama-ion e-lithium, futhi ama-molecule e-electrode angemahle ashumekwe kukhabhoni esakhiweni esinezingqimba.Ngesikhathi sokukhishwa, i-lithium ion ihlukaniswa nekhabhoni egqinsiwe futhi iphinde ihlanganiswe nenhlanganisela efakwe kahle.Amandla kagesi kwenzeka ekuhambeni kwe-lithium ion.
Nakuba isimiso sokusabela kwamakhemikhali silula kakhulu, ekukhiqizweni kwezimboni zangempela, kunezinto eziningi ezisebenzayo okufanele zicatshangelwe: idatha ye-electrode eqondile kufanele igcizelele emisebenzini yokushaja okuphindaphindiwe kwezithasiselo, futhi idatha ye-electrode engemihle kufanele iqukathe okwengeziwe. i-lithium ions ezingeni lokuklama isakhiwo samangqamuzana;ku I-electrolyte egcwaliswe phakathi kwe-electrode ephozithivu kanye ne-electrode eyinegethivu, ngaphezu kokuzinza, iphinde ibe ne-conductivity enhle kakhulu yokunciphisa ukumelana kwebhethri.
Nakuba ibhethri ye-lithium-ion cishe ingenawo umthelela wokukhumbula, umthamo wayo usazokwehla ngemva kokushaja okuphindaphindiwe, okubangelwa ngokuyinhloko izinguquko kudatha enhle nebi ngokwayo.Kusukela ezingeni lamangqamuzana, ukwakheka kwe-cavity ye-lithium ion kuma-electrode aqondile noma angalungile izowa kancane kancane futhi ivimbe.Ngokombono wamakhemikhali, kungukudlula komsebenzi wedatha we-electrode eqondile kanye ne-electrode engalungile, nezinye izinhlanganisela ezizinzile ekuphenduleni kwesibili zivela.Kukhona nezimo ezithile zomzimba, njengokukhumula kancane kancane idatha ye-electrode ephozithivu, okuzogcina kunciphise inani lama-ion e-lithium ebhethrini, okulivumela ukuthi lihambe ngokukhululeka phakathi nokushaja nokukhipha.
Ukushajwa ngokweqile kanye nokukhishwa kwenza umonakalo unomphela kuma-electrode amabhethri e-lithium-ion.Kusukela ezingeni lamangqamuzana, kungaqondwa ngokunembile ukuthi ukukhishwa kwekhabhoni ye-anode kuzodala ukukhululwa ngokweqile kwe-lithium ion kanye nokuncipha kwesakhiwo sesendlalelo, futhi ukushaja ngokweqile kuzodala kakhulu I-lithium ion ayixhunywanga esakhiweni se-cathode carbon, kanti ezinye I-lithium ion ayikwazi ukukhishwa.Yingakho amabhethri e-lithium-ion ngokuvamile efakwe amasekhethi okulawula ukushaja nokukhipha.
