1. Chigadzirwa Core
Yakakwira-Carbon Flake Graphite imhando yepamusoro-yekupedzisira graphite chigadzirwa chakagadzirwa kubva ku natural flake graphite sechinhu chekutanga, chinogadziriswa kuburikidza nekucheneswa kwemuviri (sekuyerera, kugeza acid) kana kucheneswa kwemakemikari. Hukoshi hwayo hwepakati huri mukubatanidzwa kwekuchena kwepamusoro uye yakanakisa yemuviri nemakemikari zvimiro. Icho chinhu chakakosha chehwaro chinobatanidza zviwanikwa zvegirafu nepamusoro-nzvimbo dzekupedzisira dzakadai semabhatiri e-lithium, yakakwirira-kuguma conductivity, uye kusamira kwemoto, zvichipa tsigiro huru yekuvandudza kushanda kwechigadzirwa.

3.Product Features
Kuchena kwepamusoro uye kusvibiswa kwakaderera: The fixed carbon content kazhinji iri pakati pe94% ne99.9%, uye mamwe epamusoro-madimikira ekugumisira anogona kusvika pamusoro pe99.95%; Dota rinenge rakaderera (kazhinji Zvishoma pane kana kuenzana ne0.1% -6%, zvakagadziridzwa reverse neyakagadziriswa kabhoni), uye tsvina inokuvadza yakadai sesilicon, aruminiyamu, iron, uye sulfuri inodzorwa zvakasimba pamazinga akanyanya kuderera (zvakadai sesimbi yemukati Zvisingapfuuri kana kuenzana ne0.02%, sulfur content Less than 0.
Pedzisa chikero chimiro: Chikero morphology chinogara chiripo, chine dhayamita kazhinji kubva 0.1-1.5mm uye ukobvu hwe2-10μm. The layered crystal structure is intact; Chitarisiko isirivha grey metallic luster, ine huwandu hwakawanda hwe1.0-1.6g/cm³. Yayo yakasarudzika chiyero chimiro inopa yakanakisa interlayer kutsvedza uye processability.
Excellent muviri uye makemikari zvinhu: Nekuda kwekristaro yakakwirira uye kuchena, ine yakanakisa conductivity (vhoriyamu resistivity Zvishoma pane kana kuenzana ne10μΩ · m) uye kupisa conductivity (thermal conductivity Yakakura kupfuura kana yakaenzana ne150W/(m·K)); Yakasimba tembiricha yekudzivirira, inokwanisa kumira tembiricha iri pamusoro pe3000 dhigirii munzvimbo inert, uye yakanakisa kugadzikana kwekemikari munzvimbo dzine acidic uye alkaline (kunze kweakasimba oxidizing acids), zvichiita kuti isaite ngura.
Good processing adaptability: Chimiro chechiyero chiri nyore kupwanya asi kwete nyore kuputsika kuita hupfu hwakatsetseka, zvichiita kuti zvive nyore kune inotevera kugadzirwa senge spheroidization, kuumba, kukoira, nezvimwe; Isu tinokwanisa kugadzirisa saizi yekuyera uye kuchena nhanho zvinoenderana nezvatinoda, uye kuchinjika kune akasiyana nzira dzekudzika. Semuenzaniso, lithium negative electrodes inoda zviyero zvakanaka (0.1-0.5mm), nepo refractory zvinhu zvinoda zviyero zvakakora (0.8-1.5mm).
