1. Ishingiro ry'igicuruzwa
High-Carbon Flake Graphite ni igikoresho c’ibara ry’agahama gikozwe mu gipande c’ibara ry’agahama nk’igikoresho ca mbere, gikoreshwa biciye mu gusukura umubiri (nk’uguterera, kwoza aside) canke uburyo bwo gusukura n’imiti. graphite. Agaciro kayo nyamukuru kari mu guhuza ubusuku bwinshi n’imiterere myiza cane y’umubiri n’iy’imiti. Ni ikintu nyamukuru c’ishimikiro gihuza ubutunzi bwa graphite kavukire n’ibibanza vy’iherezo ryo hejuru- nk’amabateri ya litiyumu, ubushobozi bwo gutwara umuriro, n’ubushobozi bwo guhangana n’umuriro, bitanga infashanyo nyamukuru yo gutuma ibintu bigenda neza.

3.Ibirango vy'igicuruzwa
Ubusuku bwinshi n'ubuhumane buke: Ivyimburwa vy’umuyagankuba bihoraho muri rusangi biri hagati ya 94% na 99,9%, kandi bimwe mu bimenyetso vy’agaciro kanini-bishobora gushika hejuru ya 99,95%; Ivu ririmwo ni rito cane (kenshi na kenshi Riri munsi canke ringana na 0,1% -6%, rihindurwa mu buryo buhindutse n’ibiri muri carbone bihoraho), kandi ibintu bitera ingorane nka silikoni, aluminium, icuma, n’ikibiriti biragenzurwa cane ku rugero ruto cane (nk’ivyuma birimwo Lequss canke bingana na 0.0. 0,05%), bishobora gutuma habaho uguhungabana kw’ibikorwa vy’ibicuruzwa vyo mu rwego rwo hasi.
Ubuhinga bw'urugero rwuzuye: Uburyo bw’urugero burasanzwe, busanzwe bufise umurongo uva kuri 0.1-1.5mm n’uburebure bwa 2-10μm. Igishushanyo c’ikiyo c’amabuye y’agaciro gifise ibice n’ibindi; Igishushanyo c’ifeza c’umweru w’icuma, gifise uburemere bwinshi bwa 1.0-1.6g/cm3. Igishushanyo caco kidasanzwe kiyiha ubushobozi bwiza cane bwo guterera hagati y’ibice no gukora.
Ibintu vyiza cane vy'umubiri n'ivy'imiti: Kubera uburemere bw’ikibiriti n’ubusuku bwinshi, irafise ubushobozi bwiza cane bwo gutwara umuriro (ubushobozi bwo guhangana n’umuvuduko Buke canke bungana na 10μΩ·m) n’ubushobozi bwo gutwara ubushuhe (ubushobozi bwo gutwara ubushuhe Burengeye canke bungana na 150W/(m·K)); Ishobora guhangana n’ubushuhe bwinshi cane, ishobora guhangana n’ubushuhe buri hejuru ya degre 3000 mu bidukikije bitagiramwo ibintu, kandi ishobora guhangana n’imiti myiza cane mu bidukikije bifise aside n’amazi (uretse aside zikomeye zitera oxidation), bikaba bituma idashobora gusenyuka cane.
Gutunganya neza: Igishushanyo c’umunzane kiroroshe gumenagura ariko ntikimenagurika vyoroshe ngo kibe ifu nziza, bikaba bituma gishobora gukoreshwa mu gukurikirana nk’uguhindura umupira, gubumbabumba, gupfuka, n’ibindi; Turashobora guhindura ubunini bw’urugero n’urugero rw’ubusuku bivanye n’ivyo dukeneye, kandi tukamenya guhura n’imigenderanire itandukanye y’inyuma. Nk’akarorero, ama electrode y’ivyuma bita litiyumu atari meza asaba umunzane mwiza (0,1-0,5 mm), mu gihe ibikoresho bitagira umuriro bisaba umunzane munini (0,8-1,5 mm).
4. Ikoreshwa ry'igicuruzwa
Ibikoresho nyamukuru vy'ibikoresho vya litiyumu -ion: Nk’ibikoresho vy’ishimikiro vy’ibikoresho vy’ubuhinga bwa none vy’ubushobozi bwinshi -ion negative electrodes, graphite y’umubumbe ikorwa mu buryo nk’ugumenagura, guhindura umubumbe, no gupfuka, kandi ikoreshwa mu mabateri y’inguvu (ibinyabiziga bishasha vy’inguvu), amabateri y’ububiko bw’inguvu (amabateri y’ububiko bw’inguvu (ibibanza vy’inguvu vy’ububiko bw’inguvu vy’iherezo},{lap}2); Ubusuku buhambaye burashobora kwongereza ubushobozi bwihariye bwa bateri ( Burengeye canke bungana na 360mAh/g) n’ubuzima bw’ingendo ( Burengeye canke bungana n’ingendo 2000).
Ivyuzuza ibikoresho vy'iherezo ry'iherezo -: Yongerwa ku mapulasitike, ku mipira, no ku bipfukisho kugira ngo hakorwe ibikoresho vy’ibihimba bishobora gutwara umuriro, bikoreshwa mu gupfuka ibikoresho vy’ubuhinga bwa none (anti-static), ku bipfukisho vy’amatwi vy’amabateri ya litiyumu (ibipfukisho bishobora gutwara umuyagankuba), no ku bipfukisho vy’ibikoresho vy’ubuhinga bwa none bishobora gutwara umuyagankuba; Ubuhinga bwo gutwara umuriro bushobora kugabanya ubushobozi bwo guhangana n’ibintu, gutuma ubuhinga bwo gutwara umuriro bugenda bumwe, no gushitsa ivya nkenerwa vy’ibikoresho vy’ubuhinga bwa none vy’ubuhinga buhanitse.
Ibice bidasanzwe vy'ibikoresho bishobora gusha: High-Carbon Flake Graphite ikoreshwa mu guhingura amatafari y’agaciro kanini (igipfukisho c’ifuru y’icuma), ivyuma bishobora guhangana n’umuriro (ugukingira ibihimba vy’ubushuhe bwinshi{2}}vy’ibikoresho vyo mu kirere), n’ivyuma vy’uburinzi kugira ngo bikomeze gutera; Ubusuku bwinshi n’ubushuhe bwinshi birashobora kwongereza ubushobozi bwo guhangana n’ugusenyuka kw’ibisigazwa vy’ibikoresho bishobora guhangana n’ugusenyuka kw’amabuye y’agaciro no kwagura ubuzima bwavyo (30% -50% kuruta ibikoresho bisanzwe bishobora guhangana n’umuriro vy’amabuye y’agaciro).
Amavuta y'ukuri n'ibikoresho vyo gukingira: Ikoreshwa mu gutera amavuta y’ibara ry’agahama (ikoreshwa mu gutera amavuta ku moteri z’indege no ku bihimba vy’ibikoresho vy’imashini vy’ukuri), hakoreshejwe ugunyerera hagati y’ibipande kugira ngo bigabanye umubare w’ugushikana ( Mutoyi canke ungana na 0,15); Canke zitunganijwe mu bipfukisho vy’amabuye y’agaciro (vy’ibipfukisho vy’imiyoboro n’ivy’amavalve), bifise ubushobozi bwo guhangana n’ubushuhe bwinshi n’ubuke (-200℃~600℃) n’ubushobozi bwo guhangana n’umuvuduko munini ( Muto canke bingana na 30MPa).
Ibindi bibanza vy'iherezo ryo hejuru-: Ikoreshwa mu nganda z’ibirwanisho vya kirimbuzi ibice vya graphite (ubuhumane buke burashobora kugabanya ukunywa imishwarara), ibikoresho vyo gutegura graphene (ubusuku bwinshi bugabanya ingorane zo gusukura graphene), ivyuma vy’ikaramu vy’iherezo ryinshi (uguca ibibatsi cane no kwandika neza) n’ibindi, bishingiye ku busuku n’ugutera imbere kw’imiterere.
Imisoro ishushe: graphite y'ibipande vy'umuyagankuba, Ubushinwa bw'abahinguzi b'ibipande vy'umuyagankuba
