Zvinobuda kubvagirafitimuChina yagara iri yepamusoro-soro pasi rose. Muna 2020, China ichagadzira matani 650,000 egraphite yechisikigo, zvichiita 62% yehuwandu hwepasi rose. Asi indasitiri yeupfu hwegraphite muChina iri kutarisanawo nematambudziko. Furuite graphite inotevera ichakuzivisai zvakadzama:
Chekutanga ndechekuti makambani mazhinji ekuchera nekugadzira graphite muChina ari mumamiriro ezvinhu e "kushaya simba kudiki kwakapararira", nekukura kusina kurongeka uye kukura kwemhuka kuripo, kutambisa zviwanikwa zvezvicherwa zvakanyanya uye mwero wekushandiswa wakaderera. Dambudziko rechipiri nderekuti zvigadzirwa zvechisikigo zvegraphite muChina zvinonyanya kuve zvigadzirwa zvikuru, uye kukosha kwakawedzerwa kwezvigadzirwa zvegraphite kwakaderera, uye zvigadzirwa zvepamusoro-soro zvinonyanya kuvimba nezvinotengeswa kunze kwenyika. Chechitatu inyaya yekuremerwa kwezvirambidzo zvezvakatipoteredza, uye kugadzirwa kweupfu hwegraphite kwakasimbiswa nekudzora nharaunda. Maitiro ekuchera, kushambidza uye kuchenesa upfu hwegraphite hwechisikigo ari nyore kugadzira guruva, kuparadza zvirimwa uye kusvibisa ivhu nemvura, nepo kumashure kuri nyore.kugadzirwaNzira dzemabhizinesi egraphite muChina dzinokonzera matambudziko ekuchengetedza nharaunda. Chechina, kumanikidzwa kwemari yevashandi, kuchera matombo muChina iindasitiri inoda vashandi vakawanda, uye mari yevashandi inodarika 10% yemari yese yekushanda. Mumakore achangopfuura, mari yevashandi muChina yakakwira nekukurumidza. Cheshanu, mari yesimba iri kuramba ichikura kumakambani egraphite.
Upfu hwegrafitiKugadzira iindasitiri inoshandisa simba rakawanda, uye mutengo wemagetsi unoita 1/4. Nekukwira kwemotokari itsva dzesimba, zvinhu zve anode zvemabhatiri e lithium zvave nzira inonyanya kukosha yekushandiswa kwe graphite. Makambani mazhinji makuru emuno akaisawo mari mumapurojekiti akadzika ekugadzirisa flake graphite, uye flake graphite yave kugadzirwa zvinhu zvakakosha; Panguva imwe chete, kubatanidzwa kwezvicherwa zvemuno kuri kuwedzerawo, uye zviwanikwa zvemhando yepamusoro zveindasitiri ye graphite zvichashandiswawo kumabhizinesi makuru nepakati; Kuwedzera kwakanyanya kwekudiwa kweindasitiri ye graphite powder kuchawedzera kukurudzira kukura kwe graphite inounzwa kunze kwenyika, uye kuchatungamirawo kugadziridzwa patsva kweindasitiri yemuno.girafiti yegandamusika.
