Uburyo bwo gukora impapuro za electrode mbi ku mpapuro za electrode mbi za bateri ya lithium ni bumwe n'ubw'ibyuma bya electrode mbi, ariko imiterere y'uburyo bikorwamo iratandukanye. Ubushyuhe bw'ikirere cy'imashini bugomba kuba ≤23℃ kandi ubushuhe bugomba kuba ≤25%. Ubucucike nyabwo bw'ibikoresho bya electrode mbi bisanzwe:

Uburyo bwo gukuba electrode mbi bukoreshwa cyane: Igipimo cyo gusubira inyuma: Gusubira inyuma rusange 4-8um Uburebure: Isahani nziza muri rusange ≈ 1.002 Uburyo bwo gukora electrode nziza ya bateri ya lithium isa n'uburyo bwo gukuramo electrode nziza, kandi byombi bigomba kugenzura imiyoboro mu cyerekezo cya X na Y. Ubushyuhe bw'ikirere cy'aho bakorera bugomba kuba ≤23℃, kandi aho amazi anyura hagomba kuba ≤-30℃. Nyuma yuko isahani nziza imaze kwitegura gukuramo, isahani nziza igomba kuma (120°C), hanyuma urupapuro rwa aluminiyumu rugahambirwa hanyuma rugapfunyikwa. Muri iki gikorwa, uburebure bw'agasanduku n'ubugari bwo gushushanya bigomba kwitabwaho. Dufashe urugero rwa **650 (nk'urwa bateri yo mu 18650), igishushanyo gifite agasanduku kagaragara ni ukureba ubufatanye bukwiye bw'agasanduku ka cathode mu gihe cyo gusudira umugozi w'inyuma n'umuzingo. Niba agasanduku k'inkingi kagaragaye igihe kirekire cyane, umurongo mugufi ushobora kubaho byoroshye hagati y'agasanduku k'inkingi n'icyuma mu gihe cyo kuzingurura. Niba agasanduku ari kagufi cyane, umupfundikizo ntushobora gushongeshwa. Kuri ubu, hari ubwoko bubiri bw'imitwe yo gusudira ikoresheje ikoranabuhanga: ifite ishusho y'umurongo n'iy'ingingo. Imirimo yo mu rugo ikunze gukoresha imitwe yo gusudira ifite umurongo bitewe n'uko umuriro ukabije n'imbaraga zo gusudira bikoreshwa. Byongeye kandi, kole ikoresha ubushyuhe bwinshi ikoreshwa mu gupfuka utubati two gusudira, ahanini kugira ngo hirindwe ibyago byo kwangirika kw'imirongo migufi iterwa n'ibice by'icyuma n'imyanda y'icyuma. Ubushyuhe bw'ikirere mu iduka bugomba kuba ≤23℃, aho amazi anyura hagomba kuba ≤-30℃, naho ubushuhe bwa cathode bugomba kuba ≤500-1000ppm.

Gutegura isahani mbiIsahani ya negatif igomba kuma (105-110°C), hanyuma impapuro za nikeli zigashyirwa hamwe hanyuma zigapfunyikwa. Uburebure bw'agasanduku k'amashanyarazi n'ubugari bwo gukora nabyo bigomba kwitabwaho. Ubushyuhe bw'ikirere cy'aho bakorera bugomba kuba ≤23℃, aho ikime giherereye hagomba kuba ≤-30℃, kandi ubushuhe bwa electrode negatif bugomba kuba ≤500-1000ppm. Gupfunyika ni ugupfunyika icyuma gitandukanya, urupapuro rwa electrode positive n'urupapuro rwa electrode negatif mu gice cy'icyuma binyuze mu mashini ipfunyika. Ihame ni ugupfunyika electrode positive na electrode negatif, hanyuma ugatandukanya electrode positive na negatif binyuze mu gitandukanya. Kubera ko electrode negatif ya sisitemu isanzwe ari electrode igenzura igishushanyo cya bateri, imiterere y'ubushobozi iri hejuru kuruta iya electrode positive, ku buryo mu gihe cyo gushyushya, Li+ ya electrode positive ishobora kubikwa mu "mwanya" wa electrode negatif. Hagomba kwitabwaho cyane imiterere y'umuvuduko w'umuyaga n'inkingi iyo ipfunyika. Umuvuduko muto cyane w'umuyaga uzagira ingaruka ku burwanyi bw'imbere n'igipimo cyo gushyiramo imiturire. Gushyuha cyane bishobora gutera ibyago byo gucika cyangwa gucika. Guhuza imiterere y'amashanyarazi bivuga aho electrode mbi, electrode nziza, n'aho itandukanya. Ubugari bwa electrode mbi ni 59.5 mm, electrode nziza ni 58 mm, naho igabanya ni 61 mm. Ibyo bitatu bihuzwa mu gihe cyo gucuranga kugira ngo hirindwe ibyago byo gucikamo uduce duto. Ubusanzwe imbaraga zo kuzunguruka ziba hagati ya 0.08-0.15Mpa ku giti cyiza, 0.08-0.15Mpa ku giti kibi, 0.08-0.15Mpa ku gice cyo hejuru, na 0.08-0.15Mpa ku gice cyo hasi. Impinduka zihariye ziterwa n'ibikoresho n'uburyo bikorwamo. Ubushyuhe bw'iki gikorwa ni ≤23℃, aho amazi anyura ni ≤-30℃, naho ubushuhe ni ≤500-1000ppm.

Mbere yuko igice cy’imbere cya bateri kiri mu gasanduku gishyirwa mu gasanduku, hakenewe ikizamini cya Hi-Pot cya 200 ~ 500V (kugira ngo hamenyekane niba bateri ifite voltage nyinshi idakoresha amashanyarazi menshi), kandi hakenewe no gusukura kugira ngo hagenzurwe neza ivumbi mbere yo gushyirwa mu gasanduku. Ingingo eshatu z’ingenzi zo kugenzura bateri za lithium ni ubushuhe, imiyoboro n’umukungugu. Nyuma y’uko igikorwa cyabanje kirangiye, shyiramo gasket yo hasi mu gice cy’imbere cya bateri, zunguza urupapuro rwa electrode rwiza ku buryo ubuso bwerekeza ku mwobo w’imbere wa bateri, hanyuma ushyiremo uhagaze mu gikonoshwa cy’icyuma cyangwa igikonoshwa cya aluminiyumu. Dufashe ubwoko bwa 18650 nk'urugero, umurambararo w’inyuma ≈ 18mm + uburebure ≈ 71.5mm. Iyo igice cy’imbere cya core cy’igikomere ari gito ugereranyije n’igice cy’imbere cya core cy’icyuma, igipimo cyo gushyiramo icyuma kiri hagati ya 97% na 98.5%. Kubera ko agaciro k’igice cy’inkingi n’urugero rw’amazi yinjira mu gihe cyo gutera nyuma bigomba kwitabwaho. Uburyo bumwe n'uburyo bwo gushyiramo ubushyuhe bw'ubuso burimo guteranya ubushyuhe bwo hejuru. Ubushyuhe bw'ikirere cy'aho bakorera bugomba kuba ≤23℃, naho ubushyuhe bw'ikime bugomba kuba ≤-40℃.

KuzungurukaIshyiramo agapira k'icyuma (ubusanzwe gakozwe mu muringa cyangwa mu cyuma) hagati mu gice cy'imbere cy'icyuma. Agapira k'icyuma gakoreshwa cyane ni Φ2.5 * 1.6mm, kandi imbaraga zo gusudira za electrode ya negative zigomba kuba ≥12N kugira ngo zibe zujuje ibisabwa. Iyo ari hasi cyane, byoroshye gutera gushonga no kudakomera imbere cyane. Iyo ari hejuru cyane, biroroshye gusudira urwego rwa nikeli ruri ku buso bw'icyuma, bigatera ingorane zihishe nko kugwa no kuvamo amazi. Gusobanukirwa byoroshye uburyo bwo gukurura urwego rw'icyuma nikeli, bigatera ingaruka mbi nko gushonga no gusohoka. Uburyo bworoshye bwo gusobanukirwa uburyo bwo gukurura urwego ni ugushyira urwego rw'icyuma ku gice cy'icyuma nta kunyeganyega. Mu gikorwa cyo gukora iyi bateri ya lithium, hagomba kwitabwaho cyane ku guhuza umuvuduko wo gusohora icyuma n'umuvuduko wo gukanda kugira ngo hirindwe gukata icyuma ku muvuduko mwinshi cyane, kandi urwego rwa nikeli rw'icyuma ruzagwa niba umuvuduko wo mu gice cy'imbere ari wo wihuta cyane cyangwa uburebure bw'icyuma buzagira ingaruka kandi gufunga icyuma bizakorwaho. Ni ngombwa kugenzura niba agaciro k'uburyo bwo gupima uburebure bw'icyuma, kwagura no gufunga icyuma byujuje ibisabwa (binyuze mu mibare ifatika n'iy'ibitekerezo). Ingano zisanzwe z'amashyiga ni 1.0, 1.2 na 1.5 mm. Nyuma yo kurangiza gukurura, imashini yose igomba kongera gukurwamo umwuka kugira ngo hirindwe imyanda y'icyuma. Ingano y'umwuka igomba kuba ≤-0.065Mpa, kandi igihe cyo gukurura umwuka kigomba kuba 1 ~ 2s. Ibisabwa mu bushyuhe bw'ikirere muri iyi workshop ni ≤23℃, naho aho amazi aturuka ni ≤-40℃. Guteka hagati ya bateri Nyuma y'amabati ya silinda azungurutswe kandi agashyirwamo umwuka, igikorwa gikurikira cyo gukora bateri ya litiyumu ni ingenzi cyane: guteka. Mu gihe cyo gukora bateri, hashyirwaho ingano runaka y'ubushuhe. Niba ubushuhe budashobora kugenzurwa mu gihe gisanzwe, imikorere n'umutekano wa bateri bizagira ingaruka zikomeye.
