Chii chinonzi Aluminium Foil?

Vanhu vazhinji vanofunga nezveReynolds Wrap pavanonzwa foil yealuminium. Munyika yebhatiri tinoreva chimwe chinhu zvachose.

LOTTE Aluminium yakaputsika pachirimwa chavo cheElizabethtown kumashure muna 2022. Ndakatyaira ndichipfuura nesaiti yekudonha kwekupedzisira uye chivako changa chasimuka, midziyo ichienda. Vakatora nzvimbo iyoyo nekuti Ford neSK vari kuvaka imba yebhatiri yeBlueOval mamaira mashanu munzira. Zvine musoro. Iwe unoda kuti mupi wako wefoil avhare paunenge uchimhanyisa matani 36,000 pagore kuburikidza netambo yekupfeka.

Iyo foil LOTTE ichagadzira ndeye cathodes. Yese lithium-ion cell ine maviri anounganidza mukati. Mhangura padivi reanode. Aluminium padivi recathode. Iyo inoshanda-NMC yako kana LFP yako kana chero chemistry yauri kushandisa-inonamirwa pamafoiri aya sekunyorova. Kana yaoma une electrode.

Vanhu vanobvunza kuti sei usingashandisi simbi imwechete kune ese ari maviri. Mhangura yaizova nyore. Imwe yekugovera cheni pane maviri.

Heino dambudziko. Mhangura inonyunguduka.

Pa cathode iwe wakagara pamusoro pe 3.5 volts kupesana ne lithium. Mhangura haigoni kubata izvozvo. Iyo oxidizes uye inopinda mune mhinduro. Samsung SDI yakaburitsa tekinoroji bulletin makore mashoma kumashure ichiratidza mhangura inotanga kuita corroding kutenderera 3.4 volts. Iwe unopedzisira uine maion emhangura anotenderera mu electrolyte yako uye pakupedzisira achiputira kunze pane anode. Ndizvo zvinouraya sero.

Aluminium oxidize zvakare asi iyo oxide layer yainoumba yakasiyana. Aluminium oxide yakakora uye yakagadzikana. Iyo inodzivirira chaizvo simbi iri pasi. The layer ingori mashoma nanometers ukobvu saka maerekitironi tunnel nepakati. Iwe unowana corrosion resistance uye conductivity panguva imwe chete.

Iyo foil pachayo itete. Tiri kutaura gumi kusvika gumi nemaviri microns kune mazhinji maseru ekugadzira. UACJ muJapan inotara marongero avo pakuwedzera kana kubvisa hafu yemicron pahupamhi. Izvo zvakaoma. Kureva pepa rekopi bepa rinotenderedza 100 microns.

Mutete zviri nani kune simba density. Yese giramu realuminium risingashande zvinhu uremu hwakafa. Vamwe vagadziri vemasero vakasundira pasi kusvika ku8 microns. The tradeoff iri kubata. Mapepa akaonda anobvarura pamutsetse wekupfekedza. Kudzora kwako kunofanira kunge kwakakwana. Imwe wrinkle uye chikamu ichocho che electrode chikara.

"Tinoona kudzvinyirirwa kwakasimba kubva kune vatengi kuti vaonde gore rega rega," mainjiniya anoshanda paMidwest coating operation akandiudza mwedzi wapera. "Midziyo inogona kuzviita asi kurambwa kwako kunokwira. Pane imwe nguva unenge uchirasikirwa nemisodzi yakawanda kupfuura yaunochengeta pakurema."

Kuchena kunokosha zvakare. Bhatiri-giredhi realuminium rinoda kuva pamusoro pe98 percent. Zvisina kuchena zvakaita sesimbi kana silicon zvinogadzira inclusions mune foil pamusoro. Izvo zvinobatanidzwa zvinova nzvimbo dzisina simba. Iyo yekupfekedza haina kunamatira zvakanaka kana iwe unowana pinholes. Chero nzira sero rinotadza QC.

Mazhinji epasi rose ebhatiri foil achiri kubva kuAsia. UACJ neToyo muJapan. LOTTE uye Dongwon muKorea. Hafu yegumi nevaviri vagadziri vakuru muChina vanosanganisira Ding Sheng neNanshan. Iyo Kentucky chirimwa ndeimwe yekutanga yakakomba kuedza pakugadzirwa kwemumba. Pane kutaura kwevamwe vari kutevera asi hapana chakasimba.

Kumasero eLFP vagadziri vazhinji vakatamira kune kabhoni-yakavharidzirwa foil. Dunmore muBristol, Pennsylvania anoita izvi. Vanoisa pasi kabhoni yakaonda yekutanga usati wapfekedza iyo inoshanda. Inobatsira nekunamatira sezvo LFP isinganamati kune isina aluminium uye sezvinoita NMC. Zvakare inocheka kuonana kuramba pane iyo interface.

Chii chimwe. Kudzokorora. Kana maseru asvika kumagumo ehupenyu unogona kuacheka uye kuparadzanisa aluminium kubva kune dema misa. Simbi yakadzorerwa inodzokera kumunyungudi. Kwete chaizvo yakavharwa loop sezvo iwe uchirasa imwe padanho rega rega asi zvirinani pane kuisa landfilling.

Ndinofanira kutaura nezve dyne value chinhu. Pamusoro simba. Iyo foil yepamusoro inofanirwa kuve yakachena zvakakwana zvekuti electrode slurry inonyorovesa iyo zvakaenzana. Iwe unoyera izvi mu dynes per centimita. Mazhinji mafungidziro anodaidza makumi matatu nemaviri kana kupfuura. Kana iyo foil yakagara muimba yekuchengetera yakarebesa uye ikatora kusvibiswa iwe uchaona slurry bead kumusoro panguva yekupfeka. Iro izuva rakaipa.

Zvakadaro. Ndiyo aluminium foil mumabhatiri. Hapana chakafanana neicho chiri mudhirowa rako rekicheni.
