Kubudirira muLithium-Ion Battery Recycling Technology

Chidzidzo chakabudiswa munguva pfupi yapfuura musi wa29 Chikunguru mumagaziniZvinhu Zvepamusoro Zvinoshandainotsanangura nzira inokurumidza, inoshanda, uye isingakuvadzi nharaunda yekudzoreredza lithium uchishandisa microwave radiation uye solvent inoora nyore nyore. Vaongorori vekuRice University muUnited States vakagadzira nzira iyi itsva, iyo inogona kudzoreredza kusvika ku50% ye lithium kubva kumakatoni ebhatiri re lithium-ion (LIB) anoshandiswa mumasekonzi makumi matatu chete, zvichigadzirisa dambudziko guru mutekinoroji yeLIB yekudzokorodza.

Parizvino, kudiwa kwe lithium, simbi chena yakaita sesirivha, kuri kuwedzera zvakanyanya, kupfuura kuwanikwa kwakawanda.

Nzira dzechinyakare dzekubvisa lithium kubva kumabhatiri akashandiswa dzinokuvadza nharaunda uye hadzina kushanda zvakanaka. Matambudziko makuru anosanganisira kusvibiswa kwe lithium uye kurasikirwa panguva yekupora, pamwe nekushandiswa kwesimba rakawanda. Sezvo lithium ichiwanzoburitswa mushure meimwe simbi, vaongorori vakatsvaga nzira dzakanangana nekupora kwe lithium.

Muchidzidzo ichi, vaongorori vakashandisa musanganiswa wecholine chloride ne ethylene glycol se deep eutectic solvent (DES). Vakamboona kuti panguva yekubviswa kweDES, ma lithium ions akakomberedzwa nema chloride ions kubva ku choline chloride uye anodonhedzwa mumushonga.

Kuti ibvise zvimwe simbi zvakaita secobalt kana nickel, choline chloride ne ethylene glycol zvinodiwa. Pakati pezvinhu izvi, choline chloride chete ndiyo inonyudza ma microwave zvinobudirira. Vaongorori vakanyudza marara ebhatiri mu solvent uye vakashandisa microwave radiation, zvichiita kuti lithium ibude kubva kune dzimwe simbi.

Kushandisa mwaranzi ye microwave mukuita uku kwakafanana nekupisa chikafu nekukurumidza mu microwave oven yekicheni. Simba rinoendeswa zvakananga kumamorekuru, zvichiita kuti reaction ikurumidze kupfuura nzira dzechinyakare dzekupisa.

Vaongorori vakaona kuti nekushanda kwema microwave, kubvisa 87% ye lithium kwakatora maminetsi gumi nemashanu, nepo kuwana mukana wakafanana wekudzoreredza nekudziisa mafuta mubhavhu kunoda maawa gumi nemaviri. Nzira iyi itsva inovandudza zvikuru kushanda kwehupfumi uye kukanganisa nharaunda kwekushandiswazve kwemabateri e lithium-ion, zvichipa mhinduro itsva inogara kwenguva refu kudambudziko riri kukura pasi rose.

Kuti uwane rumwe ruzivo nezveindasitiri uye zvigadzirwa, ndapota taura nesu:
