I. Material systemization ma&39;anoni da kuma bayanin takamaiman yanki na (m2 / g): yana nufin farfajiyar yanki na abubuwan ɓangarorin abubuwa. (Hanyar gwaji: ƙididdige ƙarar argon wanda aka tallata ta kayan nauyin naúrar).

Girman barbashi (μm): Bayanin barbashi na abu, yana nufin diamita na kayan abu. D50 yana kwatanta matsakaicin matsakaicin diamita na kayan. Ƙimar Wuta (G / CM3): Kayan yana girgiza yawan adadin naúrar girgizar inji.

Bugu da kari, akwai kuma wani abu da kansa, nau&39;in bayyanar, iyawar fitarwa, iyawar iya aiki, abun ciki na ƙazanta, da makamantansu kuma su ne ƙayyadaddun kayan aiki daban-daban. Na biyu, daban-daban kayan a cikin lantarki da kuma ta asali amfani halaye 1, conductive wakili carbon tawada conductive jamiái, m carbon, mai kyau conductive Properties, karfi adsorption, babban musamman surface area, game da 60-100 m2 / g, Its kanta ba shi da damar. Artificial graphite conductive wakili, da conductivity ne kasa matalauta fiye da carbon tawada, amma takamaiman surface yankin ne kananan, 10-30 mAh / g, wanda shi ne iya aiki, game da 290 mAh / g, wanda shi ne mafi alhẽri.

Har ila yau, akwai graphite na halitta, dangane da halayensa, ana iya amfani da shi azaman wakili mai gudanarwa, amma kuma a matsayin abu mara kyau na lantarki saboda babban iya aiki. Kuma nano-sikelin carbon fiber, mai kyau conductivity, mai kyau aiki yi, amma farashin ne tsada. 2, kayan lantarki gabaɗaya baturi ne na lithium ion, da lithium cobaltate, ƙarfinsa na gram 135-150 mAh / g, ƙarancin ƙarancin shine 3.

65-4.00 g / cc, LiCoO2 baturi ne na lithium ion yana da ingantaccen lantarki yana da buɗaɗɗen ƙarfin lantarki. Mafi girma fiye da makamashi (ka&39;idar fiye da makamashi 1068Wh / kg, ƙarfin ka&39;idar 274mAh / g), rayuwa mai tsayi, fitarwa mai sauri, amma farashin yana da tsada.

Kayan lantarki mara kyau: graphite wucin gadi, matsakaicin lokaci carbon microsphere, gyare-gyaren graphite na halitta, da sauransu. graphite wucin gadi na yau da kullun: ƙarfin gram 290-310mAh / g, ƙaddamarwa 1.45-1.

55g / ku. Matsakaicin lokaci microspheres carbon: gram iya aiki 310-320mAh / g, compaction 1.55-1.

65g / ku. Gyaran graphite na halitta: ƙarfin gram 320-340mAh / g, ƙaramin 1.55-1.

65g / ku. 3, manne yafi shahara ga PVDF, sunan sinadarai shine polyvinylidene fluoride, kuma girman danko yana shafar nauyin kwayoyin halitta, matsayi na rukuni na aiki da tsarin sarrafawa. Gabaɗaya, game da tsarin sarrafawa iri ɗaya, matsayi ɗaya na aiki ɗaya, mafi girman nauyin kwayoyin halitta, mafi girman danko, amma tare da haɓakar danko, daidaitawar slurry ya fi bayyana.

Ana amfani da CMC da SBR a cikin tsarin ruwa. CMC (carboxymethylcellulose): fari ko micro-yellow foda, kanta yana da kaddarorin haɗin kai, amma a cikin tsarin ruwa, mafi yawan amfani da shi ko kayan watsawa da SBR. SBR (madarar butadous-blene-blewell): farin bel mai haske shuɗi emulsion ruwa, polymer fili, gauraye da CMC, da bonding yi ne mafi alhẽri.

Na uku, baturi yana yin aiki mai kyau don saduwa da sharuɗɗa da yawa don kayan aiki, don yin aiki mai kyau, ba don isa ga yanayi masu zuwa ba: 1, kayan da kansa tsarin, girman girman girman ƙwayar, granules Smoothness na bayyanar; fitar da daidaituwar kwayoyin halitta masu aiki a cikin lantarki; 3, kwayoyin aiki mai aiki da wakili mai gudanarwa mai kyau lamba; 4, gudanar da hanyar sadarwa a hankali; 5, da kuma electrolyte mai kyau infiltration digiri; 6, ga kowane Good tsari yanayi don kayan Properties.
