Katleho ho Theknoloji ea ho Hlakola Battery ea Lithium-Ion

Phuputso ea morao tjena e hatisitsoeng ka July 29 korantengLisebelisoa tsa Ts'ebetso e tsoetseng pelee hlalosa mokhoa o potlakileng, o sebetsang hantle, le oa tikoloho bakeng sa ho hlaphoheloa ha lithium ho sebelisa mahlaseli a microwave le solvent e senyehang habonolo. Bafuputsi Univesithing ea Rice e United States ba thehile mokhoa ona o mocha, o ka khutlisang ho fihla ho 50% ea lithium ho tloha ho lithium-ion battery cathodes (LIB) e sebelisitsoeng ka metsotsoana e 30 feela, ho sebetsana le bothata bo boholo ho theknoloji ea ho tsosolosa LIB.

Hajoale, tlhoko ea lithium, tšepe e bosoeu bo bosoeu, e ntse e phahama, e feta phepelo.

Mekhoa ea setso ea ho khutlisa lithium ho libeteri tse sebelisitsoeng e kotsi tikolohong ebile ha e sebetse hantle. Liphephetso tse kholo li kenyelletsa tšilafalo le tahlehelo ea lithium nakong ea ts'ebetso ea ho hlaphoheloa, hammoho le tšebeliso e phahameng ea matla. Kaha hangata lithium e ntšoa ka mor'a litšepe tse ling, bafuputsi ba batlile mekhoa e tobileng ea ho hlaphoheloa ha lithium.

Phuputsong ena, bafuputsi ba sebelisitse motsoako oa choline chloride le ethylene glycol e le motsoako o tebileng oa eutectic (DES). Ba kile ba fumana hore nakong ea ts'ebetso ea leaching le DES, li-ion tsa lithium li pota-potiloe ke li-ion tsa chloride tse tsoang ho choline chloride ebe li kenngoa ka tharollo.

Ho hlahisa litšepe tse ling tse kang cobalt kapa nickel, ka bobeli choline chloride le ethylene glycol lia hlokahala. Har'a lintho tsena, ke choline chloride feela e monyang li-microwave ka katleho. Bafuputsi ba ile ba qoelisa litšila tsa betri ka har'a solvent mme ba sebelisa mahlaseli a microwave, e leng ho nolofalletsang ho khetha lithium leaching ho tsoa litšepe tse ling.

Ho sebelisa mahlaseli a microwave ts'ebetsong ena ho tšoana le ho futhumatsa lijo ka potlako ka ontong ea microwave ea kichineng. Matla a fetisetsoa ka kotloloho ho limolek'hule, e leng se etsang hore karabelo e be kapele ho feta mekhoa ea khale ea ho futhumatsa.

Bafuputsi ba fumane hore ka ts'ebetso ea microwave, leaching 87% ea lithium e nkile metsotso e 15, athe ho fihlela sekhahla se ts'oanang sa ho hlaphoheloa ka ho futhumatsa bate ea oli ho hloka lihora tse 12. Mokhoa ona oa mobu o ntlafatsa haholo ts'ebetso ea moruo le phello ea tikoloho ea lithium-ion battery recycling, e fanang ka tharollo e ncha e tsitsitseng bothateng bo ntseng bo eketseha ba lefats'e.

Bakeng sa lintlha tse ling tsa indasteri le lihlahisoa, ka kopo ikopanye le rona:
