Kupambana mu Lithium-Ion Battery Recycling Technology

Kafukufuku waposachedwa wofalitsidwa pa Julayi 29 m'magaziniZida Zapamwamba Zogwirira Ntchitolimafotokoza mofulumira, kothandiza, ndi chilengedwe wochezeka njira kusankha lifiyamu kuchira ntchito mayikirowevu cheza ndi mosavuta biodegradable zosungunulira. Ofufuza a Rice University ku United States apanga njira yatsopanoyi, yomwe imatha kuchira mpaka 50% ya lithiamu kuchokera ku ma cathodes a lithiamu-ion batire (LIB) m'masekondi a 30 okha, kuthana ndi vuto lalikulu laukadaulo wa LIB wobwezeretsanso.

Pakadali pano, kufunikira kwa lithiamu, chitsulo choyera-siliva, kukukulirakulira, kukulirakulira.

Njira zachikhalidwe zobwezeretsanso lithiamu kuchokera ku mabatire omwe adagwiritsidwa ntchito ndizowononga chilengedwe komanso ndizosathandiza kwambiri. Zovuta zazikuluzikulu zimaphatikizapo kuyipitsidwa kwa lithiamu ndi kutayika panthawi yobwezeretsa, komanso kugwiritsa ntchito mphamvu zambiri. Popeza lithiamu nthawi zambiri imachotsedwa pambuyo pa zitsulo zina, ofufuza afufuza njira zowunikira kuchira kwa lithiamu.

Mu phunziro ili, ochita kafukufuku anagwiritsa ntchito choline chloride ndi ethylene glycol monga deep eutectic solvent (DES). Iwo kale anapeza kuti pa leaching ndondomeko ndi DES, lithiamu ayoni wazunguliridwa ndi chloride ayoni kuchokera choline kolorayidi ndi leached mu yankho.

Kuti achotse zitsulo zina monga cobalt kapena faifi tambala, onse choline chloride ndi ethylene glycol amafunikira. Mwa zinthu izi, choline chloride yokha imayamwa ma microwave. Ofufuzawo adamiza zinyalala za batri mu zosungunulira ndikuyika ma radiation a microwave, ndikupangitsa kuti lithium leaching isankhe kuchokera kuzitsulo zina.

Kugwiritsa ntchito ma radiation a microwave pochita izi ndikofanana ndi kutenthetsa chakudya mwachangu mu uvuni wa microwave. Mphamvu zimasamutsidwa mwachindunji ku mamolekyu, zomwe zimapangitsa kuti izi zichitike mwachangu kuposa njira zachikhalidwe zotenthetsera.

Ofufuzawo adapeza kuti ndi njira ya microwave, kutulutsa 87% ya lithiamu kumatenga mphindi 15, pomwe kuchira komweko ndi kutentha kwamafuta kumafunikira maola 12. Njira yowonongekayi imapangitsa kuti chuma chitheke komanso kukhudzidwa kwa chilengedwe cha kubwezeretsanso batire ya lithiamu-ion, ndikupereka njira yatsopano yothetsera vuto lomwe likukula padziko lonse lapansi.

Kuti mudziwe zambiri zamakampani ndi malonda, chonde titumizireni:
