Ni ibihe bintu bishimangira n'itandukaniro riri hagati y'ibisabwa mu gipimo cya peteroli ya graphitized coke mu nzego zitandukanye zikoreshwa?

Hari itandukaniro rinini mu bisabwa ku gipimo cya peteroli ya graphised coke mu nzego zitandukanye zikoreshwa. Mu rwego rw'ibikoresho bya anode ya bateri ya lithium-ion, hibandwa ku mikorere ya electrochemical, ikwirakwizwa ry'ingano y'uduce, ubuso bwihariye, no kugenzura ubuziranenge. Mu buryo bunyuranye, urwego rw'imigozi ya electrode (nk'iy'imashini za graphite) rushyira imbere cyane imikorere y'amashanyarazi, imbaraga za mekanike, ubushyuhe buhamye, no kugenzura ingano y'ivu. Isesengura rirambuye riratangwa hano hepfo:

I. Umurima w'ibikoresho bya Anode ya Lithium-ion

1. Imikorere y'amashanyarazi nk'ikimenyetso cy'ingenzi

Ubushobozi bwihariye bwo Gutanga/Gusohora Ingufu: Igomba kugera kuri ≥350.0 mAh/g (National Standard GB/T 24533-2019) kugira ngo irebe ko ingufu za batiri zihagije. Ubushobozi bw'ibanze bwa Coulombic: Igisabwa cya ≥92.6% kigaragaza ubushobozi bushobora gusubizwa inyuma bw'ibikoresho mu gihe cy'izunguruka rya mbere. Ibipimo by'imiterere ya Crystal: Intera iri hagati y'indege (002) (d002) igenzurwa binyuze mu igeragezwa rya X-ray diffraction (XRD) kugira ngo hakorwe neza urugero rwa grafitis, hagabanywe inenge za lattice, kandi hongerwe uburyo electron zigenda. 2. Ingano y'uduce duto n'ubuso bwihariye

Ingano y'uduce duto: Ingano mpuzandengo y'uduce duto (D50) n'ubugari bw'uduce duto bigomba kugenzurwa kugira ngo uburyo bwo gutegura urusenda rwa batiri burusheho kuba bwiza ndetse n'ubucucike bw'ingufu z'ingano. Uduce duto twuzuza icyuho cy'uduce duto dushobora kongera ubucucike bw'uduce duto. Ubuso bwihariye: Hagomba kuba uburinganire hagati y'ibikorwa byo gukora no gutakaza ubushobozi bw'ibanze. Ubuso bwinshi bw'uduce duto butuma ikoreshwa ry'uduce duto n'ubudahangarwa bw'imbere rigabanuka, mu gihe ubuso budahagije bw'uduce duto bugabanya ubushobozi bwo gukuraho litiyumu-iyoni. 3. Kugenzura ubuziranenge n'umwanda

Ingano ya karuboni idahinduka: Ni ngombwa kugira ngo ugabanye ingaruka z'ibice bidakora ku mikorere y'amashanyarazi. Agaciro k'ubushuhe n'ubukonje: Hakenewe kugenzura neza kugira ngo hirindwe ko ubushuhe bw'ibintu bufata cyangwa ingaruka z'ibinyabutabire bihura na electrolyte, bishobora kugira ingaruka ku ituze ry'uburyo bwo gutegura ubushuhe.

II. Umwanya w'Inkoni ya Electrode (urugero, Electrode ya Graphite)

1. Ubushobozi bwo gutwara ibintu n'imbaraga za mekanike

Ubushobozi bwo guhangana n'ingufu: Igomba kuba iri hasi nk'urugero rwa μΩ·m kugira ngo igabanye igihombo cy'ingufu mu gihe cyo gukoresha electrode. Ingufu zo guhangana n'ingufu: Ingufu nyinshi zo guhangana n'ingufu zikoreshwa mu gihe cyo kuyikoresha zigomba kwirinda kwangirika. Modulus yo gushonga: Kunganya hagati yo gukomera no gukomera ni ngombwa kugira ngo hirindwe guturika bitewe n'ingufu ziterwa n'ubushyuhe cyangwa guhindagura kwa mashini. 2. Guhagarara k'ubushyuhe no kurwanya oxidation

Ingano y'ubushyuhe: Igomba kuba iri hasi kugira ngo igabanye impinduka mu bushyuhe bwinshi kandi hirindwe ko electrode n'umuriro w'itanura bitagerwaho neza. Ingano y'ivu: Igomba kuba ≤0.5% kugira ngo igabanye ingaruka z'imyanda ku kurwanya ogisijeni ya electrode. Ibintu by'icyuma biri mu ivu bishobora kwihutisha ogisijeni ya electrode no kugabanya igihe cyo kuyikora. 3. Guhindura imiterere y'imikorere

Ubucucike bw'ibice byinshi: Ubucucike bwinshi bw'ibice ni ngombwa kugira ngo hongerwe ubucucike bw'amashanyarazi no kunoza uburyo bwo gutwara no kurwanya ogisijeni. Uburyo bwo gutera no gushyiramo icyuma mu gikoresho: Guteramo icyuma inshuro nyinshi no guteramo icyuma mu gikoresho mu bushyuhe bwinshi (≥2800°C) birakenewe kugira ngo hongerwe uburyo bwa kristu kandi bigabanye ubushobozi bwo guhangana n'icyuma.

III. Ishyirwa mu bikorwa ry’ibipimo riterwa n’ikoreshwa ry’ibintu Ibikoresho bya Anode ya Lithium-ion Bateri: Bigomba kuzuza ibisabwa kugira ngo habeho ingufu nyinshi kandi birambe igihe kirekire, bityo bikaba ngombwa cyane kugira ngo habeho imikorere myiza ya elegitoroniki, ingano y’uduce duto, n’ubuziranenge. Inkoni za Electrode: Zigomba gukora neza mu gihe cy’ubushyuhe bwinshi n’ubucucike bw’umuyoboro w’amashanyarazi bwinshi, bityo bigashyirwa imbere cyane mu gutwara ibintu, imbaraga za mekanike, no kudahungabana k’ubushyuhe.
