Umkhwa wokunciphisa i-foil yobhedu ucacile.Ngo-2020, i-6μm ye-lithium yefoyile yobhedu inokuba yeyona nto iphambili kwintengiso.Kwiibhetri zamandla, kwelinye icala, i-6μm i-lithium ibhetri ye-copper foil ine-high density yamandla, iipropati ezingcono zomzimba kunye neepropati ezizinzileyo zeekhemikhali kune-8μm;kwelinye icala, inokwanelisa ngcono abavelisi beebhetri zentloko abafuna ukukhuphisana okwahlukileyo.Kulindeleke ukuba i-6μm ithathe indawo ye-8μm kulo nyaka kwaye ibe yinto eqhelekileyo kwisizukulwana esitsha se-lithium ibhetri yobhedu.
Ukuba i-6μm iba yinto eqhelekileyo kwixesha elizayo, unikezelo olutsha luya kuvela ngokuyintloko ekwandiseni imveliso ecetywayo ngumenzi, kunye nokutshintsha ukusuka kwi-8μm yendabuko ukuya kwi-6μm.Nangona kunjalo, i-lithium ibhetri ye-copper foil imboni inezithintelo ezomeleleyo zezixhobo, izithintelo zesatifikethi kunye nezithintelo zobugcisa (izinga lesivuno), okwenza kube nzima kubangenayo abatsha ukuba bangene kwixesha elifutshane;izibonakaliso eziphambili kukuthengwa kwezixhobo eziphambili (i-cathode rolls, oomatshini be-foil), kunye nemveliso entsha.Kukho ixesha lonyaka omnye lokwakha ifestile yeziseko zophuhliso kunye nexesha lovavanyo lokuvelisa lomgca.Kwangaxeshanye, umjikelo wesiqinisekiso ibhetri amandla umjikelo ifoyile yobhedu malunga nesiqingatha sonyaka, kwaye imveliso yobuninzi iya kuthatha ubuncinane malunga nesiqingatha sonyaka, okwenza ukwandiswa umthamo imveliso ayikwazi ngokukhawuleza ukubeka kwimarike ngexesha elifutshane. ixesha.Abavelisi abakhoyo bazama ukutshintshela kwi-8μm ukuya kwi-6μm, i-foil eqhelekileyo kwi-lithium copper foil, kukho izinga lokulahlekelwa kwemveliso, umahluko omkhulu kwizinga lemveliso yeshishini kunye nexesha elithile lokuguqulwa.Kulindeleke ukuba unikezelo lwe-6μm yefoyile yobhedu ye-lithium ngo-2020-2021 isenokuthi ivela kumzi-mveliso omkhulu wokuqala.
Icala lemfuno:Izinga lokungena ezantsi kwe-6μm likhula ngokukhawuleza, kwaye ukukhula kwemfuno ephezulu kuyazinza.Ngokusekwe kumyinge weebhetri ze-ternary kunye ne-lithium iron phosphate kwiifektri ezahlukeneyo zebhetri zamandla asekhaya kunye nesantya esilindelekileyo sokukhula kwemveliso, kulindeleke ukuba ukusetyenziswa kwebhetri yamandla asekhaya efoyile yobhedu ye-lithium kunokonyuka nge-31% ukuya kwiitoni ezingama-75,000 ngo-2020;apho, ukusetyenziswa kwe-6μm ifoyile yobhedu ye-lithium Kuya kwanda nge-78% ukuya kwi-46.000 yeetoni, ukwanda kweetoni ezingama-20,400, kunye nesantya sokungena kwe-6μm ibhetri yobhedu ye-lithium inokunyusa ukusuka kwi-49% ukuya kuma-65%.Ngexesha eliphakathi kunye nexesha elide, umyinge wokukhula komyinge wonyaka wemfuno ye-6μm ye-lithium ibhetri yobhedu ngo-2019-2022 nayo kulindeleke ukuba ifikelele kwi-57.7%, kunye nokukhula kwemfuno ephezulu kwixesha elizayo kunokuqhubeka.
Ubonelelo kunye neentsingiselo zemfuno:I-6μm yokubonelela kunye ne-gap yemfuno inokuvela ngo-2020, kwaye izinga lesivuno kunye nomthamo osebenzayo wemveliso uya kuqinisekisa inzuzo.Kulindeleke ukuba ngo-2020, i-lithium yelizwe i-lithium ibhetri ye-copper foil iya kutshintsha ukusuka kwi-surplus ngo-2019 ukuya kwi-gap yokubonelela kunye nemfuno, kunye nabavelisi bemfuno baya kuba bahlukeneyo;kuya kubakho i-1.5-2 iminyaka yefestile yokwandiswa kwexesha lokuguqulwa kwe-superimposed kunye nokwakhiwa komgca omtsha wemveliso, kwaye i-gap ilindeleke ukuba Qhubeka nokwandisa, i-6μm i-lithium ibhetri ye-copper foil ingaba nokunyuka kwexabiso lesakhiwo.Umthamo osebenzayo we-6μm wemveliso kunye nesantya sesivuno se-lithium ibhetri yobhedu abenzi befoil baya kugqiba umgangatho wenzuzo.Ingaba banokunyusa ngokukhawuleza i-6μm izinga lesivuno kunye nomthamo osebenzayo wemveliso iya kuba yinto ephambili yokuba abavelisi banokuyonwabela isahlulo soshishino.
