Kule minyaka yangoku,iibhetri ze-lithiumbaye bafumana ukuthandwa ngenxa yoxinano lwamandla aphezulu kunye nokusebenza okuhlala ixesha elide. Ezi bhetri ziye zaba sisiseko sokunika amandla yonke into ukusuka kwii-smartphone ukuya kwiimoto zombane. Kodwa yintoni echaza ibhetri ye-lithium kwaye iyahlula kwezinye iintlobo zeebhetri?
Ukubeka nje, ibhetri ye-lithium ibhetri ehlaziywayo esebenzisa i-ion ze-lithium njengeyona nto iphambili kwi-electrochemical reactions. Ngexesha lokutshaja nokukhupha, ezi ion zihamba ngasemva naphambili phakathi kwee-electrode ezimbini, zenza umsinga wombane. Le ntshukumo ye-lithium ion ivumela ibhetri ukuba igcine kwaye ikhulule amandla ngokufanelekileyo.
Ukuxinana kwamandla aphezulu
Enye yeempawu eziphambili ezichaza iibhetri ze-lithium kukuxinana kwamandla aphezulu. Oku kuthetha ukuba iibhetri ze-lithium zinokugcina amandla amaninzi kwiphakheji encinci kunye nekhaphukhaphu. Olu phawu lubaluleke kakhulu kwizixhobo zombane eziphathwayo njengoko zivumela ukuba zisebenze ixesha elide ngaphandle kokutshaja rhoqo. Ukongeza, ubuninzi bamandla obuphezulu beebhetri ze-lithium bubenza balungele izithuthi zombane, apho ukulungelelanisa ubunzima kunye nomthamo wokugcina kubalulekile.
Ubomi benkonzo ende
Enye inkalo eqinisekileyo yeebhetri ze-lithium bubomi babo benkonzo ende. Iibhetri ze-lithium-ion zinokungena kwimijikelo yokukhupha imali eninzi kakhulu kuneebhetri eziqhelekileyo ezinokutshajwa kwakhona ngaphandle kokulahleka okukhulu kwamandla. Ubomi obongezelelweyo bubangelwa kakhulu kuzinzo kunye nokuqina kwe-Li-ion chemistry. Ngokunyamekela kunye nokusetyenziswa okufanelekileyo, iibhetri ze-lithium zingahlala iminyaka ngaphambi kokuba zifune ukutshintshwa.
Ukusebenza kwamandla aphezulu
Ukongeza, iibhetri ze-lithium ziyaziwa ngokusebenza kwazo okuphezulu kwamandla. Izinga labo eliphantsi lokuzikhupha lithetha ukuba banokubamba intlawulo ixesha elide xa bengasetyenziswa. Oku kubenza bathembeke ngakumbi njengemithombo yamandla, njengoko inokugcinwa ixesha elide ngaphandle kokulahlekelwa amandla amaninzi. Ukongeza, iibhetri ze-lithium zinokutshaja okuphezulu kwaye zinokuhlawuliswa ngokukhawuleza kumthamo omkhulu ngexesha elifutshane.
Ukhuseleko
Ukhuseleko yenye into ephambili echaza iibhetri ze-lithium. Ngaphandle kweenzuzo zabo ezininzi, iibhetri ze-lithium ziyakwazi ukufudumala kunye nokubaleka kwe-thermal, oku kunokukhokelela kwiingozi ezikhuselekileyo ezifana nomlilo okanye ukuqhuma. Ukunciphisa le mingcipheko, iibhetri ze-lithium zihlala zixhotyiswe ngamanyathelo okukhusela afana neesekethe ezakhelwe ngaphakathi kunye nokulawula ubushushu bangaphandle. Abavelisi baphinda baqhube uvavanyo olungqongqo kwaye babambelele kwimigangatho yokhuseleko ukuqinisekisa ukhuseleko olupheleleyo lweebhetri ze-lithium.
Ukushwankathela, inkcazo yebhetri ye-lithium kukuba isebenzisa i-lithium ion njengenxalenye ephambili yokugcina amandla kunye nokukhululwa. Ezi bhetri zinezinga eliphezulu lokuxinana kwamandla okuqinisekisa ukusebenza kwexesha elide kunye nokwenza izicelo ezahlukeneyo kwizixhobo zombane eziphathwayo kunye nezithuthi zombane. Ngobomi babo obude, ukusebenza kakuhle kwamandla aphezulu, kunye neempawu zokhuseleko, iibhetri ze-lithium zibe lukhetho lokuqala lokunika amandla kwihlabathi lethu lanamhlanje. Njengoko itekhnoloji iqhubeka nokuphucula, iibhetri ze-lithium zinokudlala indima ebaluleke ngakumbi ekuhlangabezaneni neemfuno zethu zamandla.
Ukuba unomdla lithium ibhetri, wamkelekile ukuba uqhagamshelane lithium ibhetri umenzi Radiance kuFunda ngokugqithisileyo.
