Kurinda Burrs mu gukora Lithium Battery Electrode: Ibisubizo byo Gukata Inzu Isuku

Itsindaicyuma cyo gukata electrode ya lithiamu-ion, nk'ubwoko bw'ibyuma by'ingenzi by'inganda, ni ibyuma bya karubide by'uruziga byihariye byagenewe imikorere yo gukata cyane. Ibice by'amashanyarazi mu gihe cyo gukata no gukubita bateri ya li-ion biteza ibyago bikomeye by'ubwiza. Utu duce duto duto tubangamira imikorere myiza ya electrode, bigabanya ubushobozi bwa bateri ho 5-15% mu bihe bikomeye.

Ikirenzeho, ibicurane biba ibyago by’umutekano - ibizamini bya laboratwari byerekana ko n’ibice bya 20μm bishobora gutobora ibikoresho byo gutandukanya, bigatera ubushyuhe bwinshi. Ingaruka z’ubukungu ziyongera mu nzira nyinshi: imbaraga nyinshi zo mu mubiri zigabanya ubuzima bwabyo ho 30%, mu gihe igipimo cy’ibisigazwa by’ibicurane by’ibicurane gikunze kwiyongeraho 3-8% ku giciro cy’umusaruro.

Kugira ngo imitako ikore neza, abakora imitako bakeneye imitako iramba ya tungsten carbide yakozwe mu buryo bwihariye ku bikoresho bya electrode. Imitako ya Shen Gong yo gukata bateri ya li-ion igaragaza igihe kirekire kuruta ibyuma bisanzwe mu gukora buri gihe. Ibanga riri mu dushya dutatu: 1) Imitako ya karubide y'ingano nziza cyane idapfa kwangirika, 2) Imitako ya TiCN igabanya gufatana kw'umuringa/aluminium ku kigero cya 40%, na 3) kurangiza impande ku rwego rwa μm bibuza imitako ya mbere.

Uburyo bwiza bwo gukora burushaho kongera umusaruro:

• Shyiraho uburyo bwo gusimburanya ibyuma buri masaha 8 yo gukora

• Gufata uburebure bwa mm 0.15-0.3 ugereranije n'ubugari bwa electrode

• Koresha ibikoresho byo gupima hakoreshejwe laser mu isuzuma rya buri cyumweru ry'imyenda

Ku miyoboro mishya ya bateri z'imodoka zikoresha ingufu, ibyuma byacu byo hejuru/hepfo bihuye bipima ubushobozi bwo gukata buri gihe. Inyigo zerekana ko inenge ziterwa na burr zigabanuka nyuma yo guhindura sisitemu ya Shen Gong. Wibuke ko nubwo ibyuma byo gukata by'igiciro cyinshi bigura 20-30% mbere, birinda igihombo kinini cyane giterwa n'ibisigazwa by'amashanyarazi n'ibura rya bateri.

Niba ufite ibibazo byo gucika kw'amashanyarazi, nyamuneka gisha inama itsinda rya tekiniki rya ShenGong: howard@scshengong.com
