Igereranya ry'imikorere y'ubushyuhe hagati y'ishingiro rya granite n'ishingiro ry'icyuma gikozwe mu cyuma gikingira bateri ya lithium.

Ese?
Mu gikorwa cyo gukora bateri za lithium, imashini ikingira, nk'igikoresho cy'ingenzi, imikorere yayo y'ibanze igira ingaruka ku buryo butaziguye ku bijyanye no gusiga neza no ku bwiza bw'ibicuruzwa bya bateri za lithium. Ihindagurika ry'ubushyuhe ni ikintu cy'ingenzi bigira ingaruka ku buryo imashini zikingira zigumana ubushyuhe. Itandukaniro mu bushyuhe hagati y'ibice bya granite n'ibice by'icyuma byashongeshejwe ryabaye ikintu cy'ingenzi cyo kwitabwaho mu guhitamo ibikoresho mu bigo bikora bateri za lithium.
Ingano y'ubushyuhe: Akamaro k'"ubudahangarwa bw'ubushyuhe" ka granite
Igipimo cyo kwaguka k'ubushyuhe kigena uburyo ibikoresho bihagaze iyo ubushyuhe buhindutse. Igipimo cyo kwaguka k'ubushyuhe bw'ishingiro ry'icyuma gishongeshejwe ni hagati ya 10-12 × 10⁻⁶/℃. Mu bidukikije bisanzwe by'ihindagurika ry'ubushyuhe mu matsinda yo gusiga bateri ya lithium, ndetse n'impinduka nto z'ubushyuhe zishobora gutera impinduka zikomeye mu gipimo. Urugero, iyo ubushyuhe mu matsinda yo gusiga buhindukaho 5℃, ishingiro ry'icyuma gishongeshejwe rya metero 1 rishobora kwagukaho 50-60 μm no guhinduka kw'ipfundo. Uku guhinduka kuzatera impinduka mu cyuho kiri hagati y'umuzingo wo gusiga n'urupapuro rwa electrode, bigatuma ubunini bw'igipfundo butaringaniye kandi bigatera ingaruka ku bushobozi n'uburyo bateri za lithium zihagaze.

Mu buryo bunyuranye, igipimo cyo kwaguka k'ubushyuhe bw'ishingiro rya granite ni (4-8) × 10⁻⁶/℃ gusa, bingana na kimwe cya kabiri cy'icyuma gishongeshejwe. Mu gihe cy'ihindagurika ry'ubushyuhe rya 5℃, guhinduka kw'ishingiro rya granite rifite uburebure bwa metero 1 ni 20-40 μm gusa, kandi impinduka mu bipimo ishobora kwirengagizwa. Mu gihe cy'ikorwa ry'igihe kirekire, ishingiro rya granite rishobora kugumana imiterere ihamye, rigatuma habaho umwanya ukwiye hagati y'umuzingo wo gusiga n'urupapuro rwa electrode, rigakomeza guhagarara kw'ishyirwa ry'ifatizo, kandi rigatanga garanti yizewe yo gukora bateri za litiyumu zihoraho cyane.
Uburyo ubushyuhe butwara: "Uruhare rw'ubushyuhe mu gukingira ubushyuhe" ruranga granite
Uretse impinduka mu buryo busanzwe ziterwa no kwaguka k'ubushyuhe, uburyo ubushyuhe butwara ibikoresho bugira ingaruka ku buryo ubushyuhe bukwirakwira mu bikoresho bungana. Icyuma gishongeshwa gifite uburyo bwiza bwo gutwara ubushyuhe. Iyo ubushyuhe bukozwe mu mashini ikoresha moteri, gukururana kw'icyuma gishongeshwa, nibindi, icyuma gishongeshwa gitwara ubushyuhe vuba, bigatuma ubushyuhe bw'inyuma bw'icyuma buzamuka kandi bugakwirakwira mu buryo butangana. Iri tandukaniro ry'ubushyuhe rizatera ubushyuhe ku gice, bikongerere ubushyuhe. Muri icyo gihe, bishobora no kugira ingaruka ku mikorere isanzwe y'ibikoresho bipima ubuziranenge n'ibice bigenzura.
Granite ni umuyoboro mubi w’ubushyuhe, ufite ubushobozi bwo gutwara ubushyuhe bwa 2.7-3.3W/ (m · K) gusa, buri munsi cyane ugereranije n’ubw’icyuma gishongeshejwe kuri 40-60W/ (m · K). Mu gihe cy’ikoreshwa ry’imashini ikora irangi, ishingiro rya granite rishobora kubuza neza uburyo ubushyuhe bw’imbere butwara, bikagabanya ihindagurika ry’ubushyuhe ku buso bw’ibanze no gukora ubushyuhe. Nubwo imashini ikora irangi ikora igihe kirekire, ishingiro rya granite rishobora kugumana ubushyuhe buhamye, rikirinda kwangirika kw’ibikoresho no kwangirika kw’imikorere guterwa n’ubushyuhe butaringaniye, kandi rigatuma habaho ikirere gihamye cy’ubushyuhe bwo gutwara irangi.
Gutuza mu gihe cy'ubushyuhe: Ubushobozi bwa granite bwo "kurwanya ubushyuhe bw'igihe kirekire"
Gukora bateri za lithium akenshi bisaba ko ibikoresho bikora igihe kirekire. Mu gihe cy'ubushyuhe bwinshi (nk'ubukonje nijoro no gushyushya ku manywa), gukomera kw'ibikoresho by'ibanze ni ingenzi cyane. Kubera ingaruka ziyongera z'ubushyuhe no guhindagurika, ishingiro ry'icyuma gishongeshejwe rishobora kwangirika imbere, bigatuma imbaraga z'inyubako zigabanuka kandi bigira ingaruka ku buzima bw'ibikoresho. Amakuru y'ubushakashatsi agaragaza ko nyuma y'inshuro 1000 z'ubushyuhe (hamwe n'impinduka z'ubushyuhe za 20-40℃), ubujyakuzimu bw'ubuso bw'icyuma gishongeshejwe bushobora kugera kuri mm 0.1-0.2.
Ishingiro rya granite rirwanya umunaniro mwinshi bitewe n’imiterere yaryo y’imbere ya kristu. Mu gihe kimwe cyo gupima ubushyuhe, ishingiro rya granite ntirigaragaza neza imiturire, kandi imiterere yaryo igumaho igihe kirekire. Uku guhagarara neza mu gihe cy’ubushyuhe bituma ishingiro rya granite rihura n’ibisabwa mu gukora bateri ya lithium mu buryo bukomeye kandi burambye, bigabanya inshuro zo kubungabunga no guhagarika ibikoresho bitewe n’ibibazo by’ibanze no kunoza imikorere myiza y’umusaruro.
Nubwo hari ibisabwa bikomeye cyane mu gukora bateri za lithium, ishingiro rya granite, hamwe n’ubwiyongere bw’ubushyuhe, ubushobozi bwo gutwara ubushyuhe bwinshi n’ubudahangarwa budasanzwe mu gihe cy’ubushyuhe, rirusha cyane ishingiro ry’icyuma gikozwe mu byuma bicukurwa mu rwego rwo kudahangana n’ubushyuhe. Guhitamo imashini ikoresha bateri ya lithium ifite ishingiro rya granite bishobora kongera ubushobozi bwo gusiga neza, kwemeza ubuziranenge bw’ibicuruzwa bya bateri ya lithium, kugabanya ibyago by’ibikoresho mu gihe cyo gukora, no kuba inkunga y’ingenzi mu guteza imbere iterambere ry’inganda za bateri ya lithium rigana ku mikorere myiza.
