1.Kusvibisa nyaya mushure mekudzokororazve lithium iron phosphate
Musika wekudzoreredza bhatiri remagetsi wakakura, uye zvinoenderana nemasangano ekutsvagisa akakodzera, simba reChina rekuunganidza bhatiri rinowedzera rinotarisirwa kusvika 137.4MWh panosvika 2025.
Kutora lithium iron phosphate mabhatirisemuenzaniso, pane nzira mbiri dzekudzokorodza uye kushandiswa kwemabhatiri emagetsi akarega basa: imwe ndeyekushandiswa kwecascade, uye imwe ndeyekubvisa nekudzokorodza.
Kushandiswa kweCascade kunoreva kushandiswa kwemabhatiri emagetsi e-lithium iron phosphate ane simba rasara pakati pe30% kusvika 80% mushure mekudissembly uye kubatanidzwazve, uye kuaisa kunzvimbo dzine simba shoma sekuchengetedza simba.
Kubvisa uye kudzokorodza, sezita rinoratidza, kunoreva kubviswa kwe lithium iron phosphate simba mabhatiri apo yasara inokwana iri pasi pe30%, uye kudzoreredzwa kwemidziyo yavo mbishi, se lithium, phosphorus, uye iron muiyo yakanaka electrode.
Kubviswa uye kudzokororwa kwemabhatiri e-lithium-ion kunogona kuderedza kucherwa kwezvinhu zvitsva zvekuchengetedza nharaunda uye zvakare kuve nekukosha kukuru kwehupfumi, kudzikisa zvakanyanya mutengo wemigodhi, mutengo wekugadzira, mutengo wevashandi, uye mutengo wekugadzira mitsara.
Tarisiro yebhatiri relithium-ion kuputsa uye kudzokorodza kunonyanya kuve nematanho anotevera: kutanga, kuunganidza uye kuisa marara lithium mabhatiri, wobva wabvisa mabhatiri, uye pakupedzisira kupatsanura nekunatsa simbi.Mushure mekushanda, simbi dzakadzoserwa uye zvinhu zvinogona kushandiswa kugadzira mabhatiri matsva kana zvimwe zvigadzirwa, zvichichengetedza zvakanyanya mutengo.
Nekudaro, iko zvino kusanganisira boka remakambani ekudzokorodza mabhatiri, akadai seNingde Times Holding Co., Ltd. anotsigira Guangdong Bangpu Circular Technology Co., Ltd., vese vakatarisana nenyaya ine minzwa: kudzokorodza bhatiri kunoburitsa chepfu kubva-zvigadzirwa uye kuburitsa zvinosvibisa zvinokuvadza. .Musika unoda nekukurumidza matekinoroji ekuvandudza kusvibiswa uye chepfu yekudzoreredza bhatiri.
2.LBNL yakawana zvinhu zvitsva zvekugadzirisa nyaya dzekusvibiswa mushure mekugadzirisa bhatiri.
Munguva ichangopfuura, Lawrence Berkeley National Laboratory (LBNL) muUnited States yakazivisa kuti vawana chinhu chitsva chinogona kudzoreredza tsvina yelithium-ion mabhatiri nemvura chete.
Lawrence Berkeley National Laboratory yakavambwa muna 1931 uye inotungamirwa neYunivhesiti yeCalifornia kuUS Dhipatimendi reMagetsi's Sainzi Hofisi.Yakahwina 16 Nobel Prize.
Chinhu chitsva chakagadzirwa neLawrence Berkeley National Laboratory chinonzi Quick-Release Binder.Lithium-ion mabhatiri akagadzirwa kubva pane ichi chinhu anogona kudzokororwa nyore nyore, ane hushamwari kwezvakatipoteredza, uye asina chepfu.Vanongoda kuparadzaniswa chete uye kuiswa mumvura ine alkaline, uye zvinyoronyoro kuzununguswa kuti vaparadzanise zvinhu zvinodiwa.Zvadaro, simbi dzinopepetwa kubva mumvura uye dzakaomeswa.
Kana ichienzaniswa neyezvino lithium-ion recycling, iyo inosanganisira kupwanya uye kukuya mabhatiri, ichiteverwa nekupisa kwesimbi uye kupatsanurwa kwezvinhu, ine huturu hwakakomba uye kusashanda zvakanaka kwezvakatipoteredza.Nyaya itsva yakafanana neusiku nemasikati mukuenzanisa.
Mukupera kwaGunyana 2022, tekinoroji iyi yakasarudzwa seimwe ye100 yekuvandudza matekinoroji akagadzirwa pasi rose muna 2022 neR&D 100 Awards.
Sezvatinoziva, mabhatiri e-lithium-ion anosanganisira magetsi akanaka uye asina kunaka, separator, electrolyte, uye zvinhu zvekugadzirisa, asi kuti zvikamu izvi zvakabatanidzwa sei mumabhatiri e-lithium-ion hazvizivikanwi.
Mumabhatiri e-lithium-ion, chinhu chakakosha chinochengetedza chimiro chebhatiri ndiyo inonamira.
Iyo itsva Quick-Release Binder yakawanikwa naLawrence Berkeley National Laboratory vaongorori yakagadzirwa nepolyacrylic acid (PAA) uye polyethylene imine (PEI), iyo yakabatana nemabhondi pakati peatomu renitrogen rinochajiwa zvakanaka muPEI nemaatomu eokisijeni akachajiwa zvisina kunaka muPAA.
Kana Quick-Release Binder yakaiswa mumvura yealkaline ine sodium hydroxide (Na+OH-), iyo sodium ions inongoerekana yapinda panzvimbo inonamira, ichiparadzanisa mapolymer maviri.Iwo akapatsanurwa mapolymers anonyungudika mukati memvura, achiburitsa chero akamisikidzwa e electrode zvikamu.
Panyaya yemutengo, kana ichishandiswa kugadzira lithium battery positive uye negative electrodes, mutengo weadhesive iyi inenge chikamu chimwe chete mugumi chezviviri zvinonyanya kushandiswa.
