1.Litaba tsa tšilafalo ka mor'a ho sebelisa lithium iron phosphate
Mmaraka oa ts'ebetso ea betri ea matla o moholo, 'me ho latela litsi tse amehang tsa lipatlisiso, kakaretso ea betri ea matla ea China e lebelletsoeng ho fihla ho 137.4MWh ka 2025.
Ho nka lithium iron phosphate libetrie le mohlala, ho na le mekhoa e 'meli ea ho ntlafala le ho sebelisoa ha libeteri tsa motlakase tse seng li tlohetse mosebetsi: e 'ngoe ke tšebeliso ea cascade, e 'ngoe ke ea ho qhaqha le ho e sebelisa hape.
Tšebeliso ea Cascade e bolela tšebeliso ea libeteri tsa matla a lithium iron phosphate tse nang le matla a setseng pakeng tsa 30% ho isa ho 80% ka mor'a ho qhaqhoa le ho kopanngoa hape, le ho li sebelisa libakeng tse se nang matla a fokolang joalo ka polokelo ea matla.
Ho qhaqha le ho tsosolosa, joalo ka ha lebitso le bolela, ho bolela ho qhaqhoa ha libeteri tsa matla tsa lithium iron phosphate ha matla a setseng a le ka tlase ho 30%, le ho hlaphoheloa ha lisebelisoa tsa bona tse tala, tse kang lithium, phosphorus, le tšepe ka electrode e ntle.
Ho qhaqha le ho sebelisoa bocha ha libeteri tsa lithium-ion ho ka fokotsa ho rafshoa ha thepa e ncha e tala ho sireletsa tikoloho hape ho ba le boleng bo boholo ba moruo, ho fokotsa haholo litšenyehelo tsa merafo, litšenyehelo tsa tlhahiso, litšenyehelo tsa basebetsi, le litšenyehelo tsa moralo oa tlhahiso.
Sepheo sa ho qhaqha le ho tsosolosa betri ea lithium-ion haholo-holo e na le mehato e latelang: pele, bokella le ho arola litšila tsa libeteri tsa lithium, ebe o qhaqha libeteri, 'me qetellong li arole le ho hloekisa litšepe.Kamora ts'ebetso, litšepe le lisebelisoa tse hlakotsoeng li ka sebelisoa bakeng sa tlhahiso ea libeteri tse ncha kapa lihlahisoa tse ling, ho boloka litšenyehelo haholo.
Leha ho le joalo, hona joale ho kenyeletsoa sehlopha sa lik'hamphani tse nchafatsang betri, joalo ka Ningde Times Holding Co., Ltd. e leng setsi sa Guangdong Bangpu Circular Technology Co., Ltd., kaofela li tobane le bothata bo boima: ho sebelisa betri hape ho tla hlahisa lihlahisoa tse chefo le ho ntša litšila tse kotsi. .Mmaraka o hloka ka potlako mahlale a macha ho ntlafatsa tšilafalo le chefo ea ho sebelisa betri hape.
2.LBNL e fumane lisebelisoa tse ncha ho rarolla mathata a tšilafalo ka mor'a hore betri e sebelisoe hape.
Haufinyane tjena, Lawrence Berkeley National Laboratory(LBNL) ea United States e phatlalalitse hore ba fumane thepa e ncha e ka sebelisoang hape ho senya libeteri tsa lithium-ion ka metsi feela.
Lawrence Berkeley National Laboratory e thehiloe ka 1931 mme e laoloa ke Univesithi ea California bakeng sa Ofisi ea Saense ea Lefapha la Matla la US.E hapile likhau tse 16 tsa Nobel.
Thepa e ncha e qapiloeng ke Lawrence Berkeley National Laboratory e bitsoa Quick-Release Binder.Libetri tsa lithium-ion tse entsoeng ka thepa ena li ka sebelisoa hape habonolo, li baballa tikoloho, ebile ha li na chefo.Li hloka feela ho qhaqhoa ebe li kenngoa ka metsing a alkaline, 'me li sisinyeha ka bonolo ho arola likarolo tse hlokahalang.Joale, litšepe li tlhotluoa ka metsing ebe lia omisoa.
Ha ho bapisoa le recycling ea morao-rao ea lithium-ion, e kenyelletsang ho senya le ho sila libeteri, e lateloa ke ho tuka ha tšepe le likarolo tse arohaneng, e na le chefo e tebileng le ts'ebetso e mpe ea tikoloho.Boitsebiso bo bocha bo tšoana le bosiu le motšehare ha bo bapisoa.
Bofelong ba Loetse 2022, theknoloji ena e ile ea khethoa e le e 'ngoe ea mahlale a 100 a phetoho e ntlafalitsoeng lefatšeng ka bophara ka 2022 ke Likhau tsa R&D 100.
Joalokaha re tseba, libeteri tsa lithium-ion li na le li-electrode tse ntle le tse mpe, karohano, electrolyte le thepa ea mohaho, empa hore na likarolo tsena li kopantsoe joang ka libeteri tsa lithium-ion ha li tsejoe hantle.
Ka libeteri tsa lithium-ion, thepa ea bohlokoa e bolokang sebopeho sa betri ke sekhomaretsi.
Sesebelisoa se secha sa Quick-Release Binder se sibolotsoeng ke bafuputsi ba Lawrence Berkeley National Laboratory se entsoe ka polyacrylic acid (PAA) le polyethylene imine (PEI), tse hokahaneng ka litlamo lipakeng tsa liathomo tsa naetrojene tse qosoang hantle ho PEI le liathomo tsa oksijene tse qosoang hampe ho PAA.
Ha Quick-Release Binder e kenngoa metsing a alkaline a nang le sodium hydroxide (Na+OH-), li-ion tsa sodium ka tšohanyetso li kena sebakeng sa sekhomaretsi, li arola li-polymer tse peli.Li-polymer tse arohaneng li qhibiliha ka har'a mokelikeli, li lokolla lisebelisoa leha e le life tse kentsoeng tsa elektrode.
Mabapi le litšenyehelo, ha e sebelisoa ho etsa li-electrode tsa lithium battery positive le negative, theko ea sekhomaretsi sena e ka ba karolo ea leshome ho tse peli tse sebelisoang haholo.
