Iibhetri zeLithiumziye zaba yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla, zinika amandla yonke into ukusuka kwiifowuni eziphathwayo kunye neelaptops ukuya kwizithuthi zombane kunye neenkqubo zokugcina amandla ahlaziyekayo. Imbali yeebhetri ze-lithium luhambo olunomdla oluthatha amashumi eminyaka, oluphawulwe yinkqubela phambili ebalulekileyo kubuchwepheshe kunye nokuvelisa izinto ezintsha. Ukususela ekuqaleni okuthobekileyo ukuya kwindawo yazo yangoku njengezisombululo eziphambili zokugcina amandla, iibhetri ze-lithium ziye zaguqula indlela esisebenzisa nesigcina ngayo umbane.
Ukudalwa kweebhetri ze-lithium
Ibali likaiibhetri ze-lithiumIqala kwiminyaka yoo-1970, xa abaphandi baqala ukuphonononga amandla e-lithium njengesithako esiphambili kwiibhetri ezinokutshajwa kwakhona. Kwakungeli xesha apho izazinzulu zafumanisa khona iimpawu ezikhethekileyo ze-lithium, kubandakanya ubuninzi bayo bamandla aphezulu kunye nobunzima bayo obuphantsi, nto leyo eyenza ukuba ifaneleke kwizixhobo ze-elektroniki eziphathwayo. Olu fumaniso lwabeka isiseko sophuhliso lweebhetri ze-lithium-ion, eziya kuqhubeka zilawula imarike ye-elektroniki yabathengi kwiminyaka ezayo.
Ngo-1979, isazi semichiza kwiYunivesithi yaseOxford uJohn Goodenough kunye neqela lakhe benza inkqubela phambili baza baphuhlisa ibhetri yokuqala ye-lithium-ion ephinde itshajwe. Lo msebenzi wokuqala wabeka isiseko sokuthengiswa kweebhetri ze-lithium-ion, ezifumana udumo ngokukhawuleza ngenxa yokusebenza kwazo okuphezulu kunye nobomi benkonzo obude xa kuthelekiswa neebhetri zemveli ze-lead-acid kunye ne-nickel-cadmium.
Kuyo yonke iminyaka yoo-1980 noo-1990, uphando olukhulu kunye nemizamo yophuhliso igxile ekuphuculeni ukusebenza kunye nokhuseleko lweebhetri ze-lithium. Enye yeengxaki eziphambili kukufumana i-electrolyte ezinzileyo enokumelana noxinano olukhulu lwamandla e-lithium ngaphandle kokubeka emngciphekweni ukhuseleko. Oku kukhokelele ekuphuhlisweni kweendlela ezahlukeneyo ze-electrolyte kunye neenkqubo zolawulo lweebhetri eziphucula kakhulu ukuthembeka kunye nokhuseleko lweebhetri ze-lithium-ion.
Ukuphumelela kweebhetri ze-lithium

Kwiminyaka yoo-2000 yokuqala kwaphawula utshintsho olukhulu kwiibhetri ze-lithium, kunye nenkqubela phambili kwi-nanotechnology nakwisayensi yezinto ezisetyenziswayo eyakhuthaza uphuhliso lweebhetri ze-lithium iron phosphate (LiFePO4) kunye ne-lithium polymer. Ezi khemikhali zebhetri zintsha zibonelela ngoxinano olukhulu lwamandla, amandla okutshaja ngokukhawuleza kunye neempawu zokhuseleko eziphuculweyo, zikhulisa ngakumbi ukusetyenziswa kweebhetri ze-lithium kwicandelo leemoto, i-aerospace kunye namandla avuselelekayo.
Ikamva leebhetri ze-lithium
Ukwamkelwa ngokubanzi kwezithuthi zombane (ii-EV) kunye nemfuno ekhulayo yezisombululo zokugcina amandla kuye kwakhokelela ekuphuhlisweni kokusebenza okuphezulu.iibhetri ze-lithiumKwiminyaka yakutshanje, inkqubela phambili enkulu kubuchwepheshe bebhetri efana nee-electrolytes eziqinileyo kunye nee-silicon anodes ziphucule ngakumbi uxinano lwamandla kunye nobomi bomjikelo weebhetri ze-lithium, nto leyo eyenza ukuba zibe lukhetho olufanelekileyo lokugcina amandla amakhulu kunye nokuzinza kwegridi.
Imbali yeebhetri ze-lithium ibonisa ukuphishekela izinto ezintsha ngokungenasiphelo kunye namandla okuguqula ubuchwepheshe. Namhlanje, iibhetri ze-lithium zisisiseko sotshintsho lwamandla acocekileyo, okuvumela ukwamkelwa ngokubanzi kwezithuthi zombane kunye nokuhlanganiswa kwamandla ahlaziyekayo. Njengoko ihlabathi lifuna ukunciphisa ukuxhomekeka kwalo kumafutha efosili kunye nokulwa notshintsho lwemozulu, iibhetri ze-lithium ziya kudlala indima ebalulekileyo ekubumbeni ikamva elizinzileyo nelingenakhabhoni ininzi.
Isiphelo
Ukushwankathela, imbali yophuhlisoiibhetri ze-lithiumluhambo olumangalisayo lokufumanisa isayensi, ubugcisa obutsha, kunye notshintsho kwezoshishino. Ukususela kwiintsuku zabo zokuqala njengezinto ezinomdla kwelebhu ukuya kwimeko yabo yangoku njengezisombululo zokugcina amandla ezixhaphakileyo, iibhetri ze-lithium zihambe indlela ende ekunikeni amandla kwihlabathi lanamhlanje. Njengoko siqhubeka nokuvula amandla apheleleyo eebhetri ze-lithium, siza kungenisa ixesha elitsha lokugcina amandla okucocekileyo, okuthembekileyo nokuzinzileyo okuya kuyila ikamva leplanethi yethu.
