Pane zvakawanda zvehunyanzvi zvechiratidzo zve graphite zvigadzirwa, uye zvinonyanya kuenderana nezvinhu zvepamhepo, tapa density, tray dentity, kutanga kuridza mhere, kutanga kugona, etc. Mukuwedzera, pane electrochemical zviratidzo senge cycle performance, chiyero chekuita, kuzvimba, uye zvichingodaro. Saka, ndedzipi zviratidzo zvechiratidzo zve graphite zvinogadzirwa? Iyo inotevera zvemukati yakaunzwa kwauri neHcmilling (Guilin Hongcheng), Mugadziri wezvinhu zvino Grage.

01 yakatarwa nzvimbo nzvimbo

Inoreva nzvimbo yemukati yechinhu pane yuniti misa. Iyo diki iyo chidimbu, iyo yakakura nzvimbo yakananga nzvimbo.

Iyo isina kunaka yemagetsi ine zvidiki zvidiki uye yakakwira mamiriro ekunze ine zvimwe nzira uye nzira pfupi yedhium ion inotama, uye chiyero chacho chiri nani. Nekudaro, nekuda kwenzvimbo yakakura yekubatana neElectrolyte, iyo nzvimbo yekuumba iyo yemifirimu yeSei iri zvakare yakakura, uye yekutanga kugona kuchave kwakaderera. . Zvikamu zvakakura, kune rumwe rutivi, iva nemabudiro ekukatyamadza kwakanyanya.

Iyo chaiyo nzvimbo yemusoro weiyo graphite anode zvinhu zviri nani kupfuura 5m2 / g.

02 Particle Saizi Kugoverwa

Simba rezvikamu zvechikuru cheMafiripiti echigrafiti zvinhu zvekuita kwayo kweElectroemical.

Saizi yeTaperity density ichakanganisa zvakananga nehuku simba rezvinyorwa zvezvinyorwa, uye chete zvakakodzera zviyero zvekuparadzira zvinhu zvinogona kuwedzera mashandiro ezvinyorwa.

03 Tapa density

Iyo tap dentity ndeye huwandu hwehuwandu hwehuwandu hwehuwandu hwakayerwa nehuwandu hunoita kuti hupfu hunoratidzwe mune yakasimba yekuisa fomu. Icho chinongedzo chakakosha kuyera zvinyorwa zvinoshanda. Iyo vhoriyamu yeiyo lithium-ion bhatiri ishoma. Kana iyo tap dentity yakakwira, iyo Active zvinhu payuniti vhoriyamu ine huwandu hwakakura, uye huwandu hwehuwandu hwakakwira hwakakwira.

04 combicction density

Iyo density density inonyanya kuve yeiyo pure chidimbu, chinoreva density mushure mekutenderera mushure mekunge kugadzirwa kwechidimbu cheElectrode. ukobvu hwemhangura foil).

Iyo yekufananidza density inoenderana zvakanyanya nepepa chaiyo yekugona, kushanda kwayo, kupokana kwemukati uye bhatiri cycle performance.

Kufurira zvinhu zvekufananidza density: Chikamu chehukuru, kugovera uye morphology zvese zvine mhedzisiro.

05 Chokwadi Density

Kurema kwechinhu chakasimba pane huwandu huwandu hwezvinhu zviri mumamiriro ezvinhu akasviba zvachose (kunze kwemukati memukati).

Sezvo iyo yechokwadi density yakayerwa mune yakaumbwa mamiriro, ichave yakakwirira kupfuura iyo yakabiwa dentity. Kazhinji, density yechokwadi> enzaniswa density> yakabiwa density.

06 Yekutanga kubhadharisa uye kuraswa chaiko kugona

Iyo graphite anode zvinhu zvine usinga tsanangurike mukutanga kubhadharwa-discharge kutenderera. Munguva yekutanga yekuchaja yekuchaja yeiyo lithium-ion battery, iyo yeAnode yeAyod yeLithium muLithium muElectrolyte inoiswa, uye pamusoro peiyo anode iyo yeAnocs inogadzirisa kuumba. Firimu rePassivation. Chete mushure mekunge iyo isina kunaka yemagetsi yakavharwa zvachose neyesi firimu, iyo molecules isingagoni kuwirirana, uye kuita kwakamiswa. Chizvarwa cheFirimu SEI chinodya chikamu cheLithium ion, uye chikamu cheLithium Ions

07 Yekutanga Coulomb inoshanda

Chinyorwa chakakosha chekuongorora mashandiro eAnode zvinhu ndezvekutanga mari yekutanga-yekubvisa, inozivikanwa zvakare seyekutanga coulomb inoshanda. Kekutanga, iyo coulombi inoshanda yakananga inosarudza kuita kweiyo electrode zvinyorwa.

Sezvo iyo shafirimu ifirimu inonyanya kuumbwa pamusoro pechinhu cheElectrode, iyo nzvimbo yakatarwa yezvinhu electrode inobata zvakananga nzvimbo yekuumbwa kweiyo sei firimu. Iyo yakakura iyo nzvimbo yakatarwa nzvimbo, yakakura nzvimbo yekuonana neyemagetsi uye yakakura nzvimbo yekuumba iyo sei firimu.

Zvinowanzofungidzirwa kuti kuumbwa kweiyo yakagadzikana yeiyo firimu inobatsira pakubhadhara uye kuyerera kwebhatiri, uye iyo isingaenzaniswi yemafirimu haina kugadzikana, iyo ichapedza lectrolyte, yakakora ubvu hwemafirimu ei shafirimu, uye wedzera kuramba kwemukati.

08 Cycle Performance

Kuita kwekutenderera kwebhatiri kunoreva huwandu hwemari yekupomerwa uye kuendesa izvo zviitiko zvebhatiri pasi pechimwe bhata uye kuraswa hutongi kana bhatiri kugona kudonhedza kune kukosha kwakataurwa. Panyaya yekuita cycle performance, iyo shai yemafirimu ichadzivirira kusiyana kweiyo lithium ion kune imwe nhanho. Sezvo huwandu hweshamo dzinowedzera, iyo shafirimu iri icharamba ichiwira pasi, uye kuiswa pamusoro peiyo yakasarudzika yekudzikisira kweiyo mamiriro eakasiyana electrode, iyo inounza kupisa kuunganidzwa uye kurasikirwa kwekuwedzera .

09 kuwedzera

Pane kuwirirana kwakanaka pakati pekuwedzera uye hupenyu hwedentha. Mushure mekunge Electrode isina kunaka inowedzera, kutanga, mhepo yemhepo icharemara, iyo yakasarudzika yemagetsi magetsi ichaumba marara, iyo shafirimu iri ichaputswa, iyo Elecrolyte ichapera, uye kuita kwekutenderera kuchaderera; Chechipiri, diaphragm ichaderedzwa. Dzvinyiriro, kunyanya yekuwedzera kwe diaphragm kugwara renzeve yedare, iri nyore kwazvo, uye zviri nyore kukonzera micro-simbi lithium yakatsvaira nekufambira mberi kwekutenderera.

Kusvika pakuwedzera pachako, lithium ions ichave yakanyorwa muGriphite Interlayer ichipindirana panguva yekuita graphcation yekubatanidza, zvichikonzera kuwedzera kweiyo inopindira uye kuwedzera vhoriyamu. Izvi zvinowedzera chikamu hachina kuchinjika. Huwandu hwekuwedzera hune hukama nehuwandu hwekutarisa kweiyo isina kunaka electrode, iyo degree reExientation = i004 / i110, iyo inogona kuverengerwa kubva kuXD data. Iyo Anisotropic graphite zvinhu zvinowanzoita kuti uwedzere kuwedzerwa mune imwe nzira (iyo C-axis kutungamira kweiyo graphist Crycation, iyo ichaguma nekuwedzera kukuru kwebhatiri.

10Rate Performance

Dispinussion of Lithium ion muGrathi Graphite Chinyorwa chine ukuru hwakasimba, kureva kuti, zvinogona chete kuiswa perpendicular kusvika pakupedzisira kwechiso cheC-axis yeiyo graphite crystal. Iyo anode inokanganisa nezvidimbu zvidiki uye zvakakwirira zvakananga nzvimbo ine nzvimbo iri nani kuita. Uye zvakare, iyo electrode pamusoro pekuramba (nekuda kweiyo sei firimu) uye iyo electrode concivity inokanganisa zvakare chiyero chekuita.

Zvakafanana neyekutenderera hupenyu uye kuwedzera, iyo isotropic yakaipa Electrode ine akawanda lithium ion yekufambisa, iyo inogadzirisa matambudziko eshoma uye akaderera akasiyana madhiri mune anisotropic chimiro. Mazhinji emidziyo yekushandisa tekinoroji akadai seyakaganhurana uye kuunganidza kuti vavandudze zviyero zvavo.

Hcmilling (Guilin Hongcheng) mugadziri weAnode zvinhu zvekukuya.Hlmx Serieszvinhu zvino Super-fine vertical zviro, Hchzvinhu zvino Ultra-yakanaka chilluye imwe graphite yekukuya chigayo inogadzirwa nesu yakave ichishandiswa zvakanyanya mukugadzirwa kwe graphite zvinhu. Kana iwe uine zvinodiwa zvine chekuita, ndapota taura nesu kuti uwane ruzivo rwemidziyo uye tipe tevera ruzivo kwatiri:
