Inowanzo shandiswa lithium ion bhatiri kudzoreredza tekinoroji uye chimiro chekusimudzira

Munyori: Iflowpower - Inotakurika Power Station Mutengesi

Nekukurumidza kusimudzira nzanga, yedu lithium-ion bhatiri recycling tekinoroji iri kukurawo nekukurumidza. Saka iwe unonzwisisa ruzivo rwakadzama rwe lithium-ion bhatiri zvinhu zvekudzoreredza tekinoroji? Tevere, rega Xiaobian atungamirire munhu wese kuti adzidze zvakawanda nezve ruzivo. Lithium-ion mabhatiri ane huwandu hwakawanda hwekushandisa, nekushandiswa kwemapiritsi, smartphones uye supernators, inotarisirwa kunge iri kutenderera 2020, uye kushandiswa kwechinyakare mabhatiri madiki e-lithium-ion achapa maitiro makuru matsva.

Panguva imwecheteyo, dambudziko rekudzokorora kwenhamba huru yemabhatiri e-lithium-ion inonyanya kuoneka, vachishandisa nzira dzechinyakare dzakadai semarara, kupisa, nezvimwewo, izvo zvinoparadza, uye zvakatipoteredza zvakakonzera kusvibiswa, uye kunyange kupa hutano hwevanhu. Hazard.

Parizvino, nyika yangu yave yakakosha lithium-ion bhatiri inogadzira uye inoshandiswa munyika, uye kushandiswa kwebhatiri kwasvika 8 bhiriyoni. Kana iwe usina kurongeka kugadziridzwa kwemabhatiri e-lithium-ion akasiiwa, kutambisa zvakanyanya zviwanikwa, kusvibisa nharaunda, uye kukuvadza hutano hwevanhu. Zvinogona kuoneka kuti musika wekudzokorodza wemarara lithium ion mabhatiri akafara.

Iyo lithium ion bhatiri ine yakanaka electrode plate uye negative electrode plate, binder, electrolyte, uye separator. Muindasitiri, mugadziri akakosha kushandisa lithium cobalt-cobaltate, lithium manganate, nickel-manganese acid lithium ternary material uye lithium iron phosphate sechinhu chakanaka, graphite yepanyama uye graphite yakagadzirwa sechinhu chinoputika chinoshanda. Polyvinylidene fluoride (PVDF) inoshandiswa zvakanyanya yakanaka electrode adhesive ine yakakwira viscosity, yakanaka kugadzikana kwemakemikari uye zvimiro zvemuviri.

Kugadzirwa kwemaindasitiri e lithium ion mabhatiri Kushandisa kwakakosha mhinduro yelithium hexafluorophosphate (LiPF6) uye organic solvent se electrolyte, uye organic film senge polyethylene (PE) uye polypropylene (PP) inoshandiswa sebhatiri diaphragm. Lithium-ion mabhatiri anowanzo kutariswa kwezvakatipoteredza-ane hushamwari uye asingasvibise mabhatiri egirinhi, asi iyo lithium-ion bhatiri kudzoreredza kuchakonzerawo kusvibiswa. Kunyangwe mabhatiri e-lithium-ion asina muchetura uremu simbi senge mercury, cadmium uye lead, asi pesvedzero yeyakanaka uye yakaipa electrode zvinhu, electrolyte, nezvimwe.

yebhatiri ichiri yakakura. Kune rimwe divi, nekuda kwemusika mukuru wekudiwa kwemabhatiri e-lithium ion, nhamba huru yemabhatiri e-lithium ion achaonekwa mune ramangwana. Maitiro ekuita neaya mabhatiri e-lithium-ion uye kuderedza maitiro avo pane zvakatipoteredza idambudziko rekukurumidzira.

Nekune rimwe divi, kuti isangane nekudiwa kukuru kwemusika, iyo lithium-ion bhatiri inogadzira inofanirwa kuburitsa huwandu hukuru hwemabhatiri e-lithium-ion kupa musika. Mabhatiri eLithium ion anowanzo kuumbwa nesimbi dzinorema, organic compounds, uye mapurasitiki, ane huwandu hwakawanda hweheavy metal account ye15% -37%, uye organic compounds inotora 15%, uye mapurasitiki anoita 7%. Kazhinji, mukugadzirwa kwe lithium ion bhatiri, iyo yakanaka electrode inoshanda zvinhu, kureva, heavy metals, nharaunda, uye ine yakakwirira kudzoreredza kukosha.

Iyo yekudzoreredza maitiro emarara lithium ion mabhatiri akakosha kusanganisira pretreatment, yechipiri kugadzirisa uye kudzika kwekugadzirisa. Sezvo kuchine mamwe magetsi asara mubhatiri remarara, iyo pretreatment process inosanganisira kudzika kwekuburitsa maitiro, kupwanya uye kurongedza kwemuviri. Chinangwa chekurapa kwechipiri ndechekuparadzanisa zvachose yakanaka uye yakaipa electrode inoshanda zvinhu uye substrates.

Kazhinji yakanyungudutswa uchishandisa kupisa kurapwa uye organic solvent. Alkali solubility uye electrolysis nzira inoziva kupatsanurwa kwakakwana kwezvose zviri zviviri; kudzika kurapwa Kunokosha kunosanganisira maitiro maviri, kupatsanurwa, uye kuchenesa maitiro maviri ekubvisa zvakakosha simbi zvinhu. Zvinoenderana nechikamu chemaitiro ekubvisa, iyo bhatiri yekudzoreredza nzira inogona kukamurwa muzvikamu zvitatu: yakaoma kupora, kunyorova kupora uye biological kupora.

Iyo yekunyorovesa kudzoreredza maitiro inoputswa uye kunyungudutswa uchishandisa yakakodzera kemikari reagent, uyezve nekusarudza yakapatsanura zvinhu zvesimbi mumhinduro yekusvibisa kuti ibudise yakadzoserwa yakakwira-giredhi simbi cobalt kana lithium carbonate, nezvimwe. Iyo yekunyorovesa kudzoreredza maitiro akanyanya kukodzera kudzoreredza kwemakemikari zvikamu zvine marara imwe chete lithium-ion bhatiri, ine yakaderera mutengo wemidziyo, uye yakakodzera kudzoreredza diki uye yepakati-saizi yakarongwa tsvina lithium-ion mabhatiri. Nokudaro, nzira yacho ikozvino inoshandiswa zvakanyanya.

Dry recovery inoreva zvakananga kudzoreredza zvinhu kana simbi dzinokosha pasina midhiya senge mhinduro. Pakati pavo, nzira inokosha yekushandisa yakaparadzaniswa mumuviri uye kupisa kwakanyanya. Mishra et al.

Inoshandiswa kudzoreredza cobalt uye lithium mumarara-anorasa lithium ion bhatiri uchishandisa eosinophilic oxide, uye mhedzisiro yenguva yeleaching, tembiricha, kukurumidza kukurumidza uye zvimwe zvinhu pane leaching mhedzisiro yesimbi cobalt mumarara lithium ion mabhatiri. Mhedzisiro yacho inoratidza kuti kunyangwe nzira iyi ichipa nzira nyowani yekudzoreredza zvinhu zvecobalt, iyo leaching rate ye lithium acidophilic acid yakadzikira. Mune ramangwana, bhakitiriya rine mwero wekurima wepamusoro unofananidzwa nedzimwe nzira, iyo biological leaching nzira ine shoma shoma yeasidhi, mutengo uri nyore, uye kukanganisa kwezvakatipoteredza kudiki.

Izvo zviri pamusoro apa ndeye kuongororwa kwakadzama kweruzivo rwekudzoreredza tekinoroji ye lithium ion bhatiri zvinhu. Izvo zvinodikanwa kuti urambe uchiunganidza ruzivo rwakakodzera mukuita, kuti iwe ugone kugadzira zvigadzirwa zviri nani uye zvirinani kusimudzira nharaunda yedu.
