Kugadzira: pendi yehunyanzvi yekuongorora

Sezvatinoziva tese, iyo negative electrode yelithium bhatiri ialuminium foil, uye iyo yakaipa electrode ndeyemhangura foil. Mushure mekuputira, iyo anode coil uye anode coil inogadzirwa kuti iwedzere kugadziriswa. Hunhu hwema electrode hunosarudza mamwe mabasa ebhatiri, uye kupfekedzwa kweiyo substrate chikamu chakakosha cheiyo yese bhatiri yekugadzira maitiro!

Kubva pane yepakutanga dip coating coating method, iyo yakanyanya kukwirisa mbiri-sided coating inowedzerwa kuti ivandudze kunaka uye tafura yebasa rejasi. Mamwe mayuniti ehupfumi ehupfumi, kuitira kuti aite solid-state lithium bhatiri kushanda, anosuma yakawanda inodhura yekune dzimwe nyika Pole piece coating muchina.

Coating general process: Iyo yekuputira muchina kuburitsa mudziyo unopfeka iyo substrate (foil). Yekutanga layer uye yekupedzisira layer ye substrate yakabatana ne splicing chikuva kuti iite tambo inoenderera, iyo inozopihwa mumudziyo wekupfekedza nedhishi rekugadzirisa tension uye rinoshanda rekugadzirisa mudziyo kuburikidza netension mudziyo. Zvinoenderana nehuwandu hwekuputira uye kureba kweiyo isina chinhu, chigamba chinoitwa pamidziyo yekupfekedza. Muchidimbu chemativi maviri, kureba kwe-pre-coating uye kuvhara mabheji ari kushingaira kuteverwa. Iyo yakavharwa yakanyorova electrode inotumirwa mune inofinha slot yekufinha, uye tembiricha inofinha inogadzikwa zvinoenderana nekumhanya kwekupfeka uye ukobvu hwekuputira. Mushure mekufinha kweplate tension kugadziridzwa uye kushingaira kururamisa, inotevera mhepo inofema maitiro inoitwa.

Pole chidimbu coating ukobvu, coating uwandu, yakaoma mutoro. Kuboora mhepo inopisa iko zvino kwave kushandiswa zvakanyanya. Iyo yakanaka electrode substrate ndeye aruminiyamu foil, iyo ine inoshanda zvakanyanya makemikari ehupfumi uye iri nyore oxidized. Mukugadzira foil yealuminium, firimu rakatetepa reoxide rinoumbwa kudzivirira kuwedzera oxidation yealuminium foil. Nekuti iyo oxide firimu yakatetepa, ine porous uye yakapfava, ine yakanaka adsorption performance, asi yakakwirira tembiricha uye yakakwirira humidity inoparadza iyo oxide firimu uye inomhanyisa kuita oxidation. Chinhu chinonyanya kukosha iye zvino ndiyo imwe-sided coating method. Kune rumwe rutivi, kana chifukidzo chekutanga chikapedzwa zvachose kumhepo, kuvhara (mafuta), mhepo yakaoma inopisa inenge 130 ° C, kana mvura yemvura yemhepo inopisa isiri Inobatsira kutonga kuchawedzera aluminium oxide foil uye. kukanganisa anode zvinhu uye aluminium foil glue, uye kunyange kuumba madonhwe emvura mumatambudziko akakomba.

Vagadziri vesangano reAmerican neJapan vakagadzira tekinoroji yemativi maviri-yakapetwa kaviri yekuisa basa rimwe chete-layer coating uye aluminium foil oxidation, iyo inogadzirisa zvachose dambudziko realuminium foil coating oxidation. Nekudaro, mutengo weaviri-sided coating muchina haugone kuwanikwa nevanogadzira mabhatiri.
