Enye yezinsimbi ezibalulekile emhlabeni ithusi. Ngaphandle kwayo, asikwazi ukwenza izinto esizithatha kalula njengokukhanyisa izibani noma ukubukela i-TV. Ithusi imithambo eyenza amakhompyutha asebenze. Besingeke sikwazi ukuhamba ngezimoto ezingenakhopha. Ezokuxhumana zizoyeka ukufa. Futhi amabhethri e-lithium-ion abengeke asebenze nhlobo ngaphandle kwawo.
Amabhethri e-lithium-ion asebenzisa izinsimbi ezifana nethusi ne-aluminium ukuze akhe ishaji kagesi. Ibhethri ye-lithium-ion ngayinye ine-graphite anode, i-metal oxide cathode, futhi isebenzisa ama-electrolyte avikelwe isihlukanisi. Ukushaja ibhethri kubangela ama-ion e-lithium ukuthi ageleze kuma-electrolyte futhi aqoqe ku-graphite anode kanye nama-electron athunyelwe ngoxhumano. Ukunqamula ibhethri kuthumela ama-ion emuva lapho eze khona futhi kuphoqa ama-electron ukuthi adlule kusekethe edala ugesi. Ibhethri izophela uma wonke ama-ion e-lithium nama-electron ebuyela ku-cathode.
Ngakho-ke, iyiphi ingxenye yethusi edlala ngayo namabhethri e-lithium-ion? I-graphite ihlanganiswe nethusi lapho idala i-anode. I-Copper imelana ne-oxidization, okuyinqubo yamakhemikhali lapho ama-electron e-elementi eyodwa elahleka kwenye i-elementi. Lokhu kubangela ukugqwala. I-oxidization kwenzeka lapho ikhemikhali nomoya-mpilo kuhlangana ne-elementi, njengokuthi insimbi ihlangana kanjani namanzi nomoya-mpilo kudala ukugqwala. Ithusi empeleni alikwazi ukugqwala.
I-copper foilisetshenziswa ngokuyinhloko kumabhethri e-lithium-ion ngoba akukho mingcele ngosayizi wayo. Ungaba nayo inqobo nje uma ufuna futhi izacile njengoba ufuna. I-Copper ngokwemvelo yayo ingumqoqi wamanje onamandla, kodwa futhi ivumela ukuhlakazeka okukhulu nokulinganayo kwamandla wamanje.
Kunezinhlobo ezimbili ze-foil yethusi: i-rolled and electrolytic. I-foil yethusi egoqiwe eyisisekelo isetshenziselwa yonke imisebenzi yezandla nemiklamo. Idalwa ngenqubo yokwethula ukushisa ngenkathi uyicindezela phansi ngezikhonkwane ezigoqayo. Ukudala i-electrolytic copper foil ukuthi ingasetshenziswa kwezobuchwepheshe ibandakanyeka kakhulu. Iqala ngokuncibilikisa ithusi elisezingeni eliphezulu ku-asidi. Lokhu kudala i-electrolyte yethusi engangezwa ethusi ngenqubo ebizwa ngokuthi i-electrolytic plating. Kule nqubo, ugesi usetshenziselwa ukwengeza i-electrolyte yethusi kucwecwe lethusi ezigubhini ezijikelezayo ezishajwa ngogesi.
I-foil yethusi ayinawo amaphutha ayo. I-foil yethusi ingasonteka. Uma lokho kwenzeka khona-ke ukuqoqwa kwamandla kanye nokuhlakazwa kungathinteka kakhulu. Okunye futhi ukuthi ucwecwe lwethusi lungathinteka imithombo engaphandle efana namasiginali kagesi, amandla e-microwave, nokushisa okukhulu. Lezi zici zinganciphisa noma zibhubhise ikhono le-foil yethusi lokusebenza kahle. Ama-alkali namanye ama-asidi angagqwala ukusebenza kwefoyili yethusi. Yingakho izinkampani ezifanaI-CIVENIzinsimbi zakha izinhlobo eziningi zemikhiqizo ye-copper foil.
Baye bavikela ucwecwe lwethusi olulwa nokushisa nezinye izinhlobo zokugxambukela. Benza i-copper foil yemikhiqizo ethile efana namabhodi esekethe aphrintiwe (PCBs) kanye namabhodi esekethe aguquguqukayo (ama-FCB). Ngokwemvelo benza ucwecwe lwethusi lwamabhethri e-lithium-ion.
Amabhethri e-lithium-ion aba yinto evamile, ikakhulukazi ezimotweni njengoba enika amandla ama-motor induction afana nalawo akhiqizwa nguTesla. Izinjini zokungeniswa zinezingxenye ezimbalwa ezihambayo futhi zisebenza kangcono. Izinjini zokungeniswa zazibhekwa njengezingatholakali izidingo zamandla ezazingatholakali ngaleso sikhathi. U-Tesla ukwazile ukwenza lokhu kwenzeke ngamaseli ebhethri e-lithium-ion. Iseli ngalinye lakhiwe ngamabhethri e-lithium-ion ngamanye, wonke ane-foil yethusi.
Isidingo se-foil yethusi sesifinyelele ukuphakama kakhulu. Imakethe ye-foil yethusi yenza ama-dollar ayizigidi eziyizinkulungwane ezingu-7 zaseMelika ngo-2019 futhi kulindeleke ukuthi yenze ama-dollar ayizigidi eziyizinkulungwane ezingu-8 zaseMelika ngo-2026. Lokhu kungenxa yoshintsho embonini yezimoto ezithembisa ukushintsha kusuka ezinjini ezivuthayo zangaphakathi kuya kumabhethri e-lithium-ion. Kodwa-ke, izimoto ngeke kube yiyo yodwa imboni ethintekayo njengoba amakhompyutha nezinye izinto zikagesi zisebenzisa ucwecwe lwethusi. Lokhu kuzoqinisekisa kuphela ukuthi intengo yeucwecwe lwethusiizoqhubeka nokukhuphuka eshumini leminyaka elizayo.
Amabhethri e-lithium-ion anikezwa ilungelo lobunikazi okokuqala ngo-1976, futhi azokhiqizwa ngobuningi bokuthengisa ngo-1991. Eminyakeni eyalandela, amabhethri e-lithium-ion ayezoba adume kakhulu futhi azothuthukiswa kakhulu. Uma kubhekwa ukusetshenziswa kwazo ezimotweni, kuphephile ukusho ukuthi zizothola okunye ukusetshenziswa emhlabeni oncike kumandla avuthayo njengoba zishajwa futhi zisebenza kahle kakhulu. Amabhethri e-Lithium-ion ayikusasa lamandla, kodwa awalutho ngaphandle kwe-foil yethusi.
