Isingeniso:
Amabhethri e-lithiumUbe yingxenye ebalulekile yezimpilo zethu zansuku zonke, amandla yonke into kusuka kuma-Smartphones kanye nama-laptops ezimotweni zikagesi nezinhlelo zokugcina amandla ezivuselelekayo. Umlando wamabhethri e-lithium uluhambo oluhehayo oluthatha amashumi ambalwa eminyaka, olumakwe inqubekela phambili ebalulekile kwezobuchwepheshe kanye nokwenziwa okusha. Ukusuka ekuqothulweni okuthobekile esimweni sabo samanje njengezixazululo zokugcina amandla, amabhethri e-lithium aguqule indlela esisebenzisa ngayo nokugcina ugesi.
Ukudalwa kwamabhethri e-lithium
Indaba yeamabhethri e-lithiumIzinsuku zibuyela emuva ngo-1970s, lapho abacwaningi baqala baqala ukuhlola amandla e-lithiyumu njengezithako ezibalulekile kumabhethri aqashelwa kabusha. Kungalesi sikhathi lapho ososayensi bathola izakhiwo ezihlukile ze-lithium, kufaka phakathi ubungako bawo obuphakeme kanye nemvelo engasindi, okwenza kube kuhle kakhulu kumadivayisi we-elekthronikhi aphathekayo. Lokhu kutholwa kubeka isisekelo sokuthuthukiswa kwamabhethri e-lithium-ion, azoqhubeka nokulawula imakethe ye-elekthronikhi yabathengi iminyaka ezayo.
Ngo-1979, oxford University Chemist Chemist uJohn Oneonough neqembu lakhe baphumelela futhi bathuthukisa ibhethri lokuqala le-lithium-ion elibuyelwe kabusha. Lo msebenzi wokuphayona wabeka isisekelo sokuthengiswa kwamabhethri e-lithium-ion, atholakala ngokushesha ukuthandwa ngenxa yokusebenza kwawo okuphezulu kanye nokuphila kwenkonzo e-nickel-cadmium.
Kuwo wonke ama-1980s nango-1990s, ucwaningo olukhudlwana nemizamo yentuthuko egxile ekuthuthukiseni ukusebenza nokuphepha kwamabhethri e-lithium. Enye yezinselelo ezibalulekile ukuthola i-electrolyte ezinzile ezingamelana nobuningi bamandla aphezulu e-lithium amandla ngaphandle kokuyekethisa ukuphepha. Lokhu kuholele ekuthuthukisweni kwezakhi ezahlukahlukene ze-electrolyte nezinhlelo zokuphatha ibhethri ezithuthukisa kakhulu ukuthembeka nokuphepha kwamabhethri e-lithium-ion.
Impumelelo yamabhethri e-lithium
Kuwo wonke ama-1980s nango-1990s, ucwaningo olukhudlwana nemizamo yentuthuko egxile ekuthuthukiseni ukusebenza nokuphepha kwamabhethri e-lithium. Enye yezinselelo ezibalulekile ukuthola i-electrolyte ezinzile ezingamelana nobuningi bamandla aphezulu e-lithium amandla ngaphandle kokuyekethisa ukuphepha. Lokhu kuholele ekuthuthukisweni kwezakhi ezahlukahlukene ze-electrolyte nezinhlelo zokuphatha ibhethri ezithuthukisa kakhulu ukuthembeka nokuphepha kwamabhethri e-lithium-ion.
I-2000s yokuqala imake indawo yokuguqula amabhethri e-lithium, ngentuthuko e-nanotechnology kanye nezinto zokwakha isayensi ekhulisa ukuthuthukiswa kwe-lithium iron phosphate (Lifepo4) namabhethri e-lithium polymer. Lezi zikhundla zebhethri ezintsha zinikeza ukuqina kwamandla aphezulu, amakhono okushaja okusheshayo nezici zokuphepha ezithuthukisiwe, andise ukusetshenziswa kwamabhethri we-lithium kwizimoto, aerospace kanye nemikhakha yamandla evuselelekayo.
Ikusasa lamabhethri e-lithium
Ukwamukelwa okusabalele kwezimoto zikagesi (i-EVS) kanye nesidingo esikhulayo sezixazululo zokugcina amandla seziqhubekile ukuthuthukiswa kokusebenza okuphezuluamabhethri e-lithium. Eminyakeni yamuva nje, inqubekela phambili enkulu kubuchwepheshe bebhethri njengama-electroly ama-electroly nama-silicon anodes athuthukise ubuningi bamandla kanye nempilo yomjikelezo wamabhethri e-lithium, okwenza babe inketho efanelekile yokulondolozwa kwamandla kanye nokuqina kwegridi.
Umlando wamabhethri e-lithium ukhombisa ukuphishekela okungapheli kokuqamba amakhono namandla wezobuchwepheshe. Namuhla, amabhethri e-lithium ayitshe lezitsheni zokushintshwa kwamandla okuhlanzekile, enika amandla ukwamukelwa kwezimoto zikagesi nokuhlanganiswa kwamandla okuvuselelekayo. Njengoba izwe lifuna ukunciphisa ukuncika kwalo kumafutha okugcwala kanye nokulwa nokushintshwa kwesimo sezulu, amabhethri e-lithium azodlala indima ebalulekile ekubumbeni ikusasa lekhabhoni eliqhubekayo neliphansi.
Ukugcina
Ukufingqa, umlando wentuthuko weamabhethri e-lithiumUhambo olungajwayelekile lokutholwa kwesayensi, ubuchwepheshe obusha, kanye noguquko lwezimboni. Kusukela ezinsukwini zabo zokuqala njengezifiso zokuhlanza izimpahla ezimweni zabo zamanje njengezixazululo ze-Ubiquitous Serder Storation Solutions, amabhethri e-lithium afike kude kakhulu ekukhuliseni umhlaba wanamuhla. Njengoba siqhubeka nokuvula amandla aphelele amabhethri e-lithium, sizowela inkathi entsha yokugcina okuhlanzekile, okuthembekile nokuzinzile kwamandla okuzokwakha ikusasa lomhlaba wethu.
