Namuhla, namuhla, okuthuthuke kakhulu namuhla, ubuchwepheshe obuphezulu obuhlukahlukene buvele ezimpilweni zethu, buletha ukuphila kwethu kalula, khona-ke uyawaqonda amabhethri e-lithium-ion lawa obuchwepheshe obuphezulu angase abe nawo? Amabhethri e-lithium-ion izithako ezibalulekile Aqukethe izindlu, i-electrolyte, impahla ye-anode, impahla ye-cathode, ingcina, i-copper foil, ne-aluminium foil, njll. Phakathi kwazo, i-CO, i-Li, i-Ni ingxenyenamba enkulu ingu-5% kuya ku-15%, 2% kuya ku-7%, 0.5% kuya ku-2%, kanye nezakhi zensimbi ezifana ne-Al, Cu, Fe, kanye nenani lezingxenye ezibalulekile, i-anode Izinto ezibonakalayo kanye ne-cathode zenza cishe u-33% no-10%, kanti i-electrolyte ne-diaphragm i-30% ene-akhawunti ehloniphekile futhi engu-32% enenhlonipho.

Njengamanje, indlela yokuhlukanisa nokubuyisela ibalulekile ngokukhipha i-solvent, imvula, i-electrolysis, indlela yokushintshanisa i-ion, i-salting kanye ne-etiology. 1, ukwelashwa kusengaphambili 1.1, ukushajwa ngaphambilini: ugesi omningi osele ebhethri ye-lithium ion esetshenzisiwe kufanele ukhululwe ngokuphelele ngaphambi kokukhishwa.

Uma kungenjalo, amandla ayinsalela azogxilwa ekucutshungulweni okulandelayo, okungaholela ezingozini zokuphepha neminye imiphumela emibi. Indlela yokukhipha amabhethri e-lithium ion asetshenzisiwe ingahlukaniswa ngezinhlobo ezimbili, okungukuthi ukukhishwa ngokomzimba kanye nokukhishwa kwamakhemikhali. Phakathi kwazo, ukukhishwa ngokomzimba ukukhishwa kwe-short-circuit, okuvame ukuqandiswa emazingeni okushisa aphansi namafriji afana ne-nitrogen ewuketshezi, bese kuba yimpoqo ngokubhoboza.

1.2, ukuchotshozwa nokuhlukaniswa: inqubo yokuchotshozwa nokuhlukaniswa ibalulekile, ihlanganisa izinto ze-electrode nezinye izinto (izinto eziphilayo, njll.) nezinye izinto (izinto eziphilayo, njll.

) ngokusebenzisa izigaba eziningi zokuchotshozwa, ukuhlola nezinye izindlela zokuhlukanisa ukuze kuzuzwe ukuhlukaniswa kanye nokunothisa izinjongo zemishini. Sebenzisa indlela yokuvutha, indlela emanzi nezinye izindlela zingabuyisa izinsimbi ezibalulekile nezinhlanganisela. Ukuhlukaniswa kwemishini kungenye yezindlela ezivame ukusetshenziswa ngaphambi kokwelashwa, kulula ukubona ukucutshungulwa kokutholwa kwezimboni ezinkulu kanye namabhethri e-lithium-ion alahlwayo.

I-1.3, ukwelashwa kokushisa: Inqubo yokwelapha ukushisa ibaluleke kakhulu ukususa izinto eziphilayo ezingancibiliki, i-toner, njll., i-toner, njll.

, izinto ze-toner, nezinto zamanje zama-electrode nabaqoqi. Njengamanje, izindlela eziningi zokwelapha ukushisa ezisetshenziswayo ukushisa okuphezulu kokushisa okuvamile, kodwa kunezinkinga ezifana nokujula kokuhlukana nokungcoliswa kwemvelo. Ukuze kuthuthukiswe inqubo, eminyakeni yamuva nje, ucwaningo olwengeziwe mayelana ne-high-temperature vacuum pyrolysis.

1.4, indlela yokuncibilika: Indlela yokuncibilika isekelwe ezimisweni zokuhambisana ezifanayo, kusetshenziswa i-cathode material, i-adhesive (i-PVDF ebalulekile), i-aluminium foil nokunye ukungcola ku-solvent ye-organic ku-solvent ye-organic ukuze kuzuzwe ukuhlukaniswa nokunothisa. I-solvent eqinile ye-polar organic ngokuvamile ikhethwa ukuncibilikisa i-PVDF ku-electrode ukuze kuhlukaniswe into ebonakalayo ye-electrode ku-foil ye-aluminium yesiqoqi samanje.

2, i-dissolution leaching dissolution leaching process ye-electrode material iwukuncibilikisa kanye nokuvuza i-electrode material etholwe ngemva kokwelashwa kwangaphambili, ukuze into yensimbi entweni ye-electrode ibe isixazululo ngendlela ye-ionic, bese ihlukaniswa ngokukhetha futhi ithole i-CO yensimbi ebalulekile, Li et al. Izindlela zokuncibilikisa i-leaching Okubalulekile kufaka phakathi ukucwiliswa kwamakhemikhali kanye ne-biological leaching. 2.

I-1, i-chemical leaching: Indlela yendabuko ye-leaching yamakhemikhali ukufeza ukuchithwa kanye nokucwiliswa kwezinto ze-electrode ngokucwiliswa kwe-asidi noma i-alkaline, kubalulekile ukufaka indlela yesinyathelo se-leaching kanye nendlela ye-leaching yezinyathelo ezimbili. Indlela ye-leaching yesinyathelo esisodwa ngokuvamile isebenzisa i-asidi ye-inorganic HCl, i-HNO3, i-H2SO4, njll., izinto zika-electrode ezincibilike ngokuqondile njenge-ejenti yokucwilisa, kodwa le ndlela izovela amagesi ayingozi njenge-CL2, SO2, ngakho-ke khipha igesi yokwelapha.

2.2, indlela yokufundisa ngebhayoloji: Ngokuthuthuka kobuchwepheshe, ubuchwepheshe be-biometrial bunomkhuba ongcono wokuthuthuka kanye namathemba okusebenzisa kanye nezinzuzo zabo ezisebenzayo, ezinobungani kwemvelo kanye nezindleko eziphansi. I-Biological leaching iwukusebenzisa amagciwane ukuze i-oxidize insimbi ibe yisixazululo ngendlela ye-ionic.

Eminyakeni yamuva nje, abanye abacwaningi baye bahlola izindlela zokukhishwa kwebhethri ye-lithium ion kadoti. 3. Ukuhlukaniswa nokubuyiselwa kwezinto ezibalulekile zensimbi oketshezini oluvuzayo 3.

I-1, indlela yokukhipha i-solvent: indlela yokukhipha i-solvent okwamanje isetshenziswa kabanzi ekuhlukaniseni nasekubuyiseleni izakhi zensimbi kumabhethri e-lithium ion kadoti. Isimiso siwukusebenzisa i-solvent ephilayo ukuze kwakhe inkimbinkimbi ezinzile ne-ion ehlosiwe esixazululweni se-leaching, bese uyihlukanisa kusetshenziswa i-solvent efanelekile ye-organic ukuze kukhishwe insimbi ehlosiwe kanye nenhlanganisela. 3.

2, indlela yemvula: Indlela yemvula ukuncibilikisa ibhethri ye-lithium ion kadoti ekhishwe ngaphambili futhi yathola isisombululo se-CO ne-Li ngemva kokuncibilika kwe-asidi, futhi wengeze i-precipitant ukuze kulungiswe insimbi ebalulekile eqondiwe i-Co, Li, njll., ngaleyo ndlela kuzuzwe ukuhlukaniswa kwensimbi. 3.

3, i-electrolysis: I-Electrolysis iwukubuyisela izinsimbi eziyigugu kubhethri ye-lithium ion ngekhemikhali ye-electrode electrode material leaching liquid ukuze kubuyiselwe izinsimbi eziyigugu ebhethrini le-lithium ion ezintweni ezilula noma amadiphozithi. Le ndlela ayifaki ezinye izinto, kunzima ukwethula ukungcola, futhi umkhiqizo onokuhlanzeka okuphezulu ungatholakala. Kodwa-ke, ukufakwa okuphelele kuzokwenzeka phambi kwama-ion amaningi, okuzonciphisa ukuhlanzeka komkhiqizo futhi kudle amandla kagesi amaningi.
