Enye yezona metal zibalulekileyo emhlabeni yicopper. Ngaphandle kwayo, asinakukwazi ukwenza izinto esizithatha lula njengokukhanyisa izibane okanye ukubukela iTV. Icopper yimithambo-luvo eyenza iikhompyutha zisebenze. Besingenakukwazi ukuhamba ngeemoto ngaphandle kwecopper. Unxibelelwano beluya kuma lungasebenzi. Kwaye iibhetri ze-lithium-ion bezingayi kusebenza konke konke ngaphandle kwayo.
Iibhetri zeLithium-ion zisebenzisa iintsimbi ezifana nekopolo kunye nealuminiyam ukwenza itshaja yombane. Ibhetri nganye yeLithium-ion ine-graphite anode, i-metal oxide cathode, kwaye isebenzisa ii-electrolytes ezikhuselweyo ngumhlukanisi. Ukutshaja ibhetri kubangela ukuba ii-ion zeLithium zidlule kwii-electrolytes zize ziqokelele kwi-graphite anode kunye nee-electron ezithunyelwa ngoqhagamshelo. Ukukhupha ibhetri kubuyisela ii-ion apho zifike khona kwaye kunyanzela ii-electron ukuba zidlule kwisekethe zivelisa umbane. Ibhetri iya kuphelelwa xa zonke ii-ion zeLithium kunye nee-electron zibuyela kwi-cathode.
Ngoko ke, yintoni indima edlalwa yikopolo kwiibhetri ze-lithium-ion? I-Graphite idityaniswe nekopolo xa kudalwa i-anode. I-Copper ayimelani ne-oxidization, inkqubo yekhemikhali apho ii-electron zento enye zilahleka kwenye into. Oku kubangela ukubola. I-oxidization yenzeka xa ikhemikhali kunye ne-oksijini zidibana ne-element, njengokuba intsimbi idibana namanzi kwaye i-oksijini idala ukubola. I-Copper ayichaphazeleki kukubola.
Ifoyile yekopoloIsetyenziswa kakhulu kwiibhetri ze-lithium-ion kuba akukho miqathango ngobukhulu bayo. Ungayifumana ixesha elide kangangoko ufuna kwaye incinci kangangoko ufuna. I-Copper ngokwendalo yayo ngumqokeleli wamandla ombane onamandla, kodwa ikwavumela ukusasazeka okukhulu nokulinganayo kwamandla ombane.
Kukho iintlobo ezimbini ze-copper foil: egoqwe kunye ne-electrolytic. I-copper foil egoqwe ngokusisiseko isetyenziselwa zonke izinto zobugcisa kunye noyilo. Yenziwa ngenkqubo yokungenisa ubushushu ngelixa uyicinezela ngee-rolling pins. Ukudala i-copper foil e-electrolytic yinto enokusetyenziswa kwitekhnoloji ebandakanyekayo kancinci. Iqala ngokunyibilikisa i-copper esemgangathweni ophezulu kwi-asidi. Oku kudala i-electrolyte ye-copper enokongezwa kwi-copper ngenkqubo ebizwa ngokuba yi-electrolytic plating. Kule nkqubo, umbane usetyenziselwa ukongeza i-copper electrolyte kwi-copper foil kwiidrama ezijikelezayo ezitshajiweyo ngombane.
I-copper foil ayinazo iziphene zayo. I-copper foil inokugoba. Ukuba oko kuyenzeka, ukuqokelelwa kwamandla kunye nokusasazwa kwawo kunokuchaphazela kakhulu. Ngaphezu koko, i-copper foil inokuchaphazeleka yimithombo yangaphandle efana nemiqondiso ye-electromagnetic, amandla e-microwave, kunye nobushushu obugqithisileyo. Ezi zinto zinokucothisa okanye zitshabalalise amandla e-copper foil okusebenza ngokufanelekileyo. Ii-alkali kunye nezinye ii-asidi zinokulimaza ukusebenza kwe-copper foil. Yiyo loo nto iinkampani ezifanaI-CIVENIintsimbi zenza iintlobo ngeentlobo zeemveliso zefoyile yobhedu.
Bane-copper foil ekhuselayo elwa nobushushu nezinye iindlela zokuphazamiseka. Benza i-copper foil kwiimveliso ezithile ezifana nee-printed circuit boards (PCBs) kunye nee-flexible circuit boards (FCBs). Ngokwendalo benza i-copper foil kwiibhetri ze-lithium-ion.
Iibhetri zeLithium-ion ziya zisiba yinto eqhelekileyo, ingakumbi kwiimoto njengoko zinika amandla iimoto ezivuselelayo ezifana nezo ziveliswa yiTesla. Iimoto ezivuselelayo zinezinto ezimbalwa ezihambayo kwaye zisebenza ngcono. Iimoto ezivuselelayo zazithathwa njengezingenakufumaneka ngenxa yeemfuno zamandla ezazingekho ngelo xesha. ITesla yakwazi ukwenza oku kwenzeke ngeeseli zayo zebhetri yeLithium-ion. Iseli nganye yenziwe ngeebhetri zeLithium-ion nganye, zonke ezinefoyile yobhedu.
Imfuno yefoyile yobhedu ifikelele kwinqanaba eliphezulu kakhulu. Imarike yefoyile yobhedu yenze imali engaphezulu kweebhiliyoni ezisi-7 zeerandi zaseMelika ngo-2019 kwaye kulindeleke ukuba yenze imali engaphezulu kweebhiliyoni ezisi-8 zeerandi zaseMelika ngo-2026. Oku kungenxa yotshintsho kwishishini leemoto elithembisa ukutshintsha ukusuka kwiinjini zokutsha zangaphakathi ukuya kwiibhetri ze-lithium-ion. Nangona kunjalo, iimoto aziyi kuba lodwa ishishini elichaphazelekileyo njengoko iikhompyutha kunye nezinye izixhobo ze-elektroniki nazo zisebenzisa ifoyile yobhedu. Oku kuya kuqinisekisa kuphela ukuba ixabiso leifoyile yobheduiza kuqhubeka isanda kwiminyaka elishumi ezayo.
Iibhetri zeLithium-ion zaqala ukuba ne-patent ngo-1976, kwaye zaziveliswa ngobuninzi ngo-1991. Kwiminyaka eyalandelayo, iibhetri zeLithium-ion zaziya kuthandwa kakhulu kwaye zaphucuka kakhulu. Ngenxa yokusetyenziswa kwazo kwiimoto, kukhuselekile ukuthi ziya kufumana ezinye iindlela zokusetyenziswa kwihlabathi elixhomekeke kumandla atshayo njengoko zinokutshajwa kwakhona kwaye zisebenza kakuhle. Iibhetri zeLithium-ion zikamva lamandla, kodwa aziyonto ngaphandle kwefoyile yobhedu.
