Isakhiwo kanye nesimo sobuso be-graphite enwetshiwe

I-graphite enwetshiwe uhlobo lwento efana nezimpethu ezikhululekile nezingenazimbobo etholakala ku-graphite yemvelo ye-flake ngokusebenzisa i-intercalation, ukuwasha, ukomisa kanye nokwandiswa kwezinga lokushisa eliphezulu. Iyinto entsha yekhabhoni ekhululekile nengenazimbobo. Ngenxa yokufakwa kwe-ejenti ye-intercalation, umzimba we-graphite unezici zokumelana nokushisa kanye nokuqhuba kukagesi, futhi isetshenziswa kabanzi ekuvaleni, ekuvikeleni imvelo, ezintweni ezivimbela ilangabi kanye nezinto ezingashi umlilo kanye neminye imikhakha. Umhleli olandelayo we-Furuite Graphite wethula isakhiwo kanye nesimo sobuso be-graphite enwetshiwe:

Eminyakeni yamuva nje, abantu banaka kakhulu ukungcola kwemvelo, futhi imikhiqizo ye-graphite elungiselelwe ngendlela ye-electrochemical inezinzuzo zokungcoliswa okuncane kwemvelo, okuqukethwe kwe-sulfur okuphansi kanye nezindleko eziphansi. Uma i-electrolyte ingangcoliswanga, ingasetshenziswa kabusha, ngakho-ke idonsele ukunaka okukhulu. Isixazululo esixubile se-phosphoric acid kanye ne-sulfuric acid sasetshenziswa njenge-electrolyte ukunciphisa ukugcwala kwe-asidi, kanti ukwengezwa kwe-phosphoric acid nakho kwandisa ukumelana kwe-oxidation kwe-graphite enwetshiwe. I-graphite enwetshiwe elungiselelwe inomphumela omuhle wokuvimbela ilangabi uma isetshenziswa njenge-thermal insulation kanye nezinto ezingashi.

I-micro-morphology ye-flake graphite, i-graphite enwebekayo kanye ne-graphite enwebekayo yatholwa futhi yahlaziywa yi-SEM. Emazingeni okushisa aphezulu, ama-interlayer compounds ku-graphite enwebekayo azobola ukuze akhiqize izinto zegesi, futhi ukwanda kwegesi kuzokhiqiza amandla anamandla okukhulisa i-graphite eceleni kwe-C axis ukuze kwakheke i-graphite enwebekayo ngesimo se-worm. Ngakho-ke, ngenxa yokwanda, indawo ethile yobuso be-graphite enwebekayo iyakhula, kunezimbobo eziningi ezifana nezitho phakathi kwe-lamellae, isakhiwo se-lamellar siyasala, amandla e-van der Waals phakathi kwezingqimba ayabhujiswa, ama-intercalation compounds ayakhula ngokugcwele, futhi isikhala phakathi kwezingqimba ze-graphite siyanda.
