Gusukura hakoreshejwe laser mu gukora bateri z'amashanyarazi

Umusaruro wabateri za litiyumuni inzira yo "gutembera no gusogongera". Yaba bateri ya fosfeti y'icyuma ya lithium, bateri ya sodium-ion cyangwa bateri ya ternary, igomba kunyura mu nzira yo gutunganya kuva kuri filamenti nto kugeza kuri bateri imwe, hanyuma ikagera kuri sisitemu ya bateri. Uburyo bwo gutegura bateri za lithium bushobora kugabanywamo ibice bitatu: gukora electrode sheet, synthesis ya cellules, no gupakira imiti.

Hari inzira nyinshi z'ingenzi muri izi nzira eshatu z'ingenzi, zizagira ingaruka ku buryo butaziguye ku bushobozi bwa bateri bwo kubika ingufu, umutekano w'ibicuruzwa n'ubuzima bwa serivisi. Kubwibyo, imikorere ya bateri zikorwa n'uburyo butandukanye bwo gukora iratandukanye cyane. Muri izi sano,isuku ya laserubu bashobora kwitabira ibikorwa birenga icumi byo gutegura, ibyo bikaba bishobora kongera cyane ubwiza bwa bateri za lithium.

Uko icyifuzo cy'amabateri y'amashanyarazi gikomeje kwiyongera, ni ko icyifuzo cyaisuku ya laserIbikoresho nabyo biziyongera. Ubutaha, tuzibanda kuri zimwe mu nzira zo gukoresha n'inyungu zo kugereranya.

1. Gusukura icyuma gikozwe muri lazeri (copper) na aluminiyumu mbere yo gusiga irangi ku giti

Electrode nziza n'imbi za bateri ya lithium zikorwa hakoreshejwe gusiga electrode nziza n'imbi za bateri ya lithium ku rupapuro rwa aluminiyumu n'urupapuro rw'umuringa. Iyo uduce, imyanda, umukungugu n'ibindi bikoresho bivanze mu gihe cyo gusiga, bizatera umuvuduko muto w'amashanyarazi muri bateri, kandi mu bihe bikomeye, bateri izashya igaturika.

Bityo rero, agapapuro gakwiye gusukurwa mbere yo gusiga kugira ngo haboneke ubuso busukuye neza kandi budafite okiside.

Ibice bya bateri bihari muri rusange bisukurwa n'imiraba ya ultrasound, kandi umuti wa ethanol ukoreshwa nk'umuti wo gusukura mbere yo gusiga irangi. Ubu buryo bufite inenge zikurikira:

1. Iyo isukura ibice by'icyuma hakoreshejwe ikoranabuhanga, cyane cyane ibikoresho bya aluminiyumu, bigizweho ingaruka n'inshuro, igihe cyo gusukura n'imbaraga, ingaruka z'imiraba ya ultrasonic zishobora kwangiza byoroshye urupapuro rwa aluminiyumu, bigatuma habaho imyenge mito. Uko igihe cyo gukora kiba kirekire, niko imyenge iba minini.

Igikoresho gikoreshwa ku gice cya bateri ya lithium muri rusange ni igikoresho kimwe gifite ubugari bwa 10 μm, gikunze gucikamo imyobo bitewe n'ibibazo byo gusukura.

2. Gukoresha umuti wa ethanoli nk'umuti wo gusukura ntabwo byoroshye gusa kwangiza ibindi bice bya bateri ya lithium, ahubwo binatera "kugabanuka kwa hydrogen", ibyo bikaba bigira ingaruka ku miterere y'icyuma cya aluminiyumu.

3. Nubwo ingaruka zo gusukura ari mbi kurusha izo gusukura hakoreshejwe imiti isanzwe, isuku ntabwo imeze neza nk'iyo gusukura hakoreshejwe laser. Rimwe na rimwe haracyariho ibintu bihumanya ku buso, bigatuma irangi ritandukana n'urupapuro cyangwa rigatanga utwobo two gushonga.

Nk’isuku yumye idafite ibikoresho byo gukoresha, gusukura hakoreshejwe laser nta nenge ifite mu bijyanye n’isuku no kunyuranamo kw’amazi kw’urusobe rw’icyuma cya aluminiyumu, bigatuma ingano n’amabara birushaho kugira ingaruka nziza ku gice cy’inkingi.

Gukoresha icyuma gisukura hakoreshejwe laser ntibishobora kongera imikorere myiza y’isuku no kuzigama umutungo wo gusukura gusa, ahubwo binashyiraho uburyo bwo gukurikirana amakuru y’isuku mu buryo nyabwo no kumenya neza ibyavuye mu isuku, ibyo bikaba bishobora kunoza neza uburyo ibice by’inkingi bitunganywa.

2. Gusukura ibipfunyika bya bateri hakoreshejwe laser mbere yo gusudira

Utubati ni uduce tw'icyuma dusohora electrode nziza na mbi mu kazu ka bateri, kandi ni ahantu ho gukora iyo bateri ishaje kandi isohoka. Ibintu byanduza hejuru nk'amavuta, imiti ibuza ingese n'ibindi bintu muri icyo gikorwa bishobora guteza ibibazo nko gusudira nabi, kwangirika no gupfunyika mu isudi.

Isuku y'ubuso bufatanye ishobora kugira ingaruka zikomeye ku bwizerwe no kuramba kw'umuyoboro w'amashanyarazi.

Isukura ry'amashanyarazi risanzwe rikoreshwa ahanini mu gusukura intoki, gusukura imiti ikoreshwa mu mazi cyangwa gusukura plasma:

● Gusukura intoki ntabwo ari byiza kandi birahenze;

● Nubwo umurongo wo gusukura amazi ukoreshwa mu buryo butose wongera imikorere myiza, uburebure bw'umurongo ni burebure, ufata igice kinini cy'uruganda, kandi imiti ishobora kwangiza ibindi bice bya bateri ya lithiamu byoroshye;

● Nubwo gusukura plasma bidasaba igikoresho cy'amazi, bisaba kandi gazi ikoreshwa nk'ikintu gishobora gukoreshwa, kandi kuyishyiramo gazi bizatuma electrode nziza n'imbi za bateri zifunguka byoroshye. Mu kuyikoresha, akenshi biba ngombwa guhindura bateri inshuro nyinshi kugira ngo utandukanye electrode nziza n'imbi zo gusukura. Ubushobozi nyabwo ntabwo buri hejuru.

Gusukura hakoreshejwe laser bishobora gukuraho umwanda n'umukungugu neza, n'ibindi ku mpera y'inkingi ya bateri, kandi witegure gusudira bateri mbere y'igihe.

Kubera ko isuku ya laser idasaba ibikoresho nk'ibikomeye, amazi na gaze, inyubako ni nto, umwanya winjizwamo ni muto, kandi ingaruka zo gusukura ziratangaje, bishobora kunoza cyane uruziga rw'umusaruro no kugabanya ikiguzi cyo gukora;

Ishobora gukurura ubuso bwo gusudira bushingiye ku gukuraho neza ibintu bikomoka ku bimera n'uduce duto, kandi ikanoza uburyo bwo gusudira hakoreshejwe laser nyuma. Ni imwe mu mahitamo meza yo gusukura tab.

3. Gusukura kole yo hanze mu gihe cyo guteranya

Kugira ngo hirindwe impanuka z’umutekano wa bateri za lithium, muri rusange ni ngombwa gushyira kole ku tunyangingo twa bateri za lithium kugira ngo bigire uruhare mu kurinda ubushyuhe, birinde imiyoboro migufi, birinde imiyoboro, kandi birinde gushwanyagurika.

Iyo agace k'inyuma k'akaremangingo kadasukuye kapimwe na CCD, hazabaho iminkanyari, uduheri two mu mwuka, iminkanyari n'ibindi bidafite isura, kandi uduheri two mu mwuka dufite umurambararo wa 0.3mm akenshi dushobora kugaragara. Hari amahirwe yo kuva amazi no kwangirika, ibyo bigabanya igihe bateri imara kandi bikanagira ingaruka mbi ku mutekano.

Gusukura hakoreshejwe laserishobora kugera ku rwego rwa Sa3 mu bushobozi bwo gusukura ubuso bw'ingirabuzimafatizo, kandi igipimo cyo kuyikuraho kiri hejuru ya 99.9%; kandi nta stress iri ku buso bw'ingirabuzimafatizo. Ugereranyije n'ubundi buryo bwo gusukura nko gusukura hakoreshejwe ikoranabuhanga cyangwa gusya hakoreshejwe imashini, ishobora kwemeza ko ibimenyetso bifatika n'ibinyabutabire nk'ubukomere bw'ubuso bw'ingirabuzimafatizo za bateri bidahinduka cyane, kandi bikongera igihe cyo gukora bateri.

Uretse ingero zavuzwe haruguru, gusukura hakoreshejwe laser bifite izindi nyungu nyinshi mu zindi nzira nyinshi nko gukuraho irangi rya bateri ripfundikiye hakoreshejwe electrophoretic no gusukura icyapa cya foil.

Niba ushaka kumenya byinshi ku bijyanye no gusukura hakoreshejwe laser, cyangwa ushaka kugura imashini nziza yo gusukura hakoreshejwe laser, andika ubutumwa ku rubuga rwacu hanyuma utwandikire kuri imeri!
