Amaqiniso Okufanele Ukwazi

Amabhethri e-Lithium-Ion

I-lithium-ion amabhethri (LIB) yiyona ngqoqo yokuqoqwa (amabhethri) anikezela amandla aphezulu futhi ahlanganiswa njalo kumaklayenti kagesi abasebenzisi njengamagetsi e-electronic, izimoto ezingavamile, i-laptops, amafoni, ama-iPod, njll. ezinye izinhlobo zamabhethri avuselelekayo anesayizi kanye nomthamo ofanayo, i-LIBs ilula kakhulu.
Ngokungafani nebhethri eyinhloko ye-lithium, i-LIB isebenzisa i-lithium compound esikhundleni se-lithium metallic njenge-electrode yayo. Izingxenye ezinkulu zebhethri i-lithium-ion yi-electrodes yayo – i-anode ne-cathode – kanye ne-electrolyte.
Amangqamuzana amaningi ahlanganyela izingxenye ezivamile ngokwe-electrolyte, separator, foil kanye ne-casing. Umehluko omkhulu phakathi kobuchwephesha beselula yizinto ezisetshenziswayo njenge “izinto ezisebenzayo” njenge-cathode ne-anode. I-graphite yizinto ezivame ukusetshenziswa kakhulu njenge-anode, kanti i-cathode yenziwe nge-layered LiMO2 (M = Mn, Co, no-Ni), i-spinel LiMn2O4, noma i-olivine LiFePO4. I-electrolyte liquid electrolyte (isib., I-LiPF6 usawoti ehlakazwa ngenhlanganisela yezixazululo eziphilayo, njenge-ethylene carbonate (EC), i-dimethyl carbonate (DMC), i-diethyl carbonate (i-DEC), i-ethyl methyl carbonate (EMC), njll) ivumela ukunyakaza kwe-ionic.
Kuncike ezintweni eziphathekayo ezinhle (i-cathode) ne-negative (anode) ye-electrode, amandla we-energy kanye ne-voltage ye-LIBs ngokuhlukahluka.
Uma isetshenziselwa izimoto zikagesi, ngokuvamile ibhetri yemoto kagesi (EVB) noma ibhetri ye-traction isetshenziswa. Amabhethri amathrekhi anjalo asetshenziselwa imishini yokushayela, amathrekhi kagesi kagesi, ama-scrubbers ephansi, izithuthuthu zikagesi, izimoto zikagesi, amaloli, imoto kanye nezinye izimoto kagesi.

I-Metal Recycling kusuka kuma-Battery Li-I-Ion Spent

Uma kuqhathaniswa nezinye izinhlobo zamabhethri ezivame ukuqukethe i-lead noma cadmium, amabhethri e-Li-ion anezinsimbi ezinobuthi ezincane futhi ngakho-ke kubhekwa njengemvelo-friendly. Kodwa-ke, inani elikhulu lokusebenzisa amabhethri e-Li-ion, okuzodingeka ukuthi alahlwe njengama-batriji avela ezimotweni zikagesi, enikeze inkinga yokudoba. Ngakho-ke, i-loop yokuvala kabusha evaliwe ye-Li-ion amabhethri iyadingeka. Kusukela kumbono wokonga, izakhi zensimbi ezifana ne-iron, ithusi, i-nickel, i-cobalt, ne-lithium zingatholakala futhi zisebenzise kabusha ekukhiqizeni amabhethri amasha. Ukubuyisela kabusha kungavimbela nokuntuleka okuzayo, futhi.
Nakuba amabhethri ane-nickel loadings ephakeme efika emakethe, akunakwenzeka ukukhiqiza amabhethri ngaphandle kwe-cobalt. Okuqukethwe okuphezulu kwe-nickel kuza ngezindleko: Ngokuqukethwe kwe-nickel okwandisiwe, ukuzinza kwebhethri kunciphile futhi ngaleyo ndlela ukuphila komjikelezo wayo kanye nekhono lokushaja okusheshayo kuncishisiwe.

Ukuze kutholakale ukuvuselelwa kabusha kwe-loop, zonke izibopho zamakhemikhali nazo zonke izakhi kufanele zihlukaniswe ezingxenyeni zabo. Kodwa-ke, amandla adingekayo okuvuselelwa kabusha okuvaliwe okuvaliwe ayabiza kakhulu. Izinto ezibaluleke kakhulu zokulondoloza ziyizinsimbi ezinjengeNi, Co, Cu, Li, njll njengoba izimayini ezibiza kakhulu namanani aphezulu emakethe ezakhiwe zensimbi kwenza ukuvuselelwa kwezomnotho kube mnandi.
Inqubo yokuvuselela kabusha ye-Li-ion amabhethri iqala ngokuqedwa nokukhishwa kwamabhethri. Ngaphambi kokuvula ibhethri, kudinga ukungahambi ukuvimbela amakhemikhali ebhetri. Ukunyuka kungatholakala ngogesi owenziwe nge-cryogenic noma e-control oxidation. Kuye ngesayizi yebhethri, amabhethri angaqedwa futhi ahlakazwe esitokisini. Emva kokuqothula nokuchoboza, izingxenye zihlukaniswe ngezindlela ezimbalwa (isib. Ukuhlolwa, ukusikeka, ukukhipha ngesandla, ukuhlukanisa ngesandla, ukuhlukanisa ngesandla) ukuze ususe isisindo, i-aluminium, ithusi kanye nama-plastiki avela ku-electrode powder. Ukuhlukaniswa kwezinto zokwakhiwa kwe-electrode kuyadingeka emisebenzini engezansi, isib. Ukwelashwa kwe-hydrometallurgical.
I-Pyrolysis
Ukuze kusetshenziswe i-pyrolytic, amabhethri aqoshiwe abhekwa esithandweni somlilo lapho kutholakala khona umcibisholo njenge-agent-forming agent.

Izinqubo ze-Hydrothermal
Ukucubungula kwe-hydrometallurgical kusekelwe ekusebenzeni kwe-asidi ukuze kuncishiswe ama-salti njengensimbi. Izinqubo ezijwayelekile ze-hydrometallurgical zihlanganisa i-leaching, imvula, i-exchange exchange, i-solvent extraction kanye ne-electrolysis yezixazululo ezinamanzi.
Inzuzo yokucubungula kwe-hydrothermal yi-yield ephezulu yokubuyisela kwe-+ 95% ye-Ni ne-Co njengama-salts, + angu-90% we-Li angakhanjiswa, futhi konke okunye kungatholakala kuze kufike ku- + 80%.

I-cobalt ngokukhethekile iyisici esibucayi kwi-lithium ion cathodes yebhethri yezinhlelo zokusebenza eziphezulu zamandla namandla.
Izimoto ze-hybrid zamanje ezifana neToyota Prius, zisebenzisa amabhethri e-nickel metal hydride, adilizwa, alayishwa futhi avuselelwa ngendlela efanayo njengebhethri ye-Li-ion.
