Udupapuro two mu isakoshi Bateri za Lithium-Ion: Incamake yuzuye

Utwuma duto ni ingenzi cyane muri bateri za lithium-ion zo mu mufuka, dukora nk'ikiraro gihuza electrode z'imbere za bateri n'imiyoboro yo hanze. Uretse kuba ari uduhuza gusa, bigira uruhare runini mu kurinda umutekano wa bateri, gukora neza kw'ifunga, no gukora neza muri rusange. Iyi nkuru irasuzuma ubwoko, ibikoresho, imiterere y'imikorere, n'ikoreshwa ry'ibi bice by'ingenzi, itanga ubumenyi bufatika ku bakora n'abahanga.

Amabati ya batiri ni iki?

Mu gice cy’ibanze cyazo, utubati twa bateri ni imiterere igizwe n’ibice bibiri by’ingenzi: agace k’icyuma n’agapfunyika ka pulasitiki (agapfunyika ka pulasitiki). Agapfunyika k’icyuma gakora nk’umuyoboro w’amashanyarazi, gatuma umuriro w’amashanyarazi ugenda hagati y’amashanyarazi meza/akegamiye kuri bateri n’ibikoresho byo hanze. Agapfunyika ka pulasitiki, gatanga umupfundikizo wo kwirinda ko electrolyte isohoka kandi kagakingira agapfunyika k’icyuma ku miyoboro migufi.

1. Udutabo twizaubusanzwe zikozwe muri aluminiyumu (Al) bitewe n’ubushobozi bwazo bwo gutwara ibintu no kurwanya ingese.
2. Ibice bibikoresha nikeli (Ni) cyangwa umuringa ukozwe muri nikeli (Ni-Cu). Udupapuro twa nikeli dukunze gukoreshwa mu bikoresho bito bya elegitoroniki, mu gihe utupapuro twa nikeli dukozwe muri nikeli—dufite agaciro kubera ubushobozi bwazo bwo gutwara umuriro mwinshi—dukundwa cyane na bateri z'amashanyarazi n'izikoreshwa ku rwego rwo hejuru.

Gushyira mu byiciro uduce tw'amatab

Udupapuro tw’ifatizo dushyirwa mu byiciro hakurikijwe ibikoresho byatwo, ubwoko bwa kole, n’ibipfunyika, buri kimwe gihuye n’uburyo bwihariye bwo gukoreshwa:

1. Binyuze mu byuma bikozwe mu buryo bw'icyuma

1. Udupapuro twa aluminiyumu (Al): Ikoreshwa cyane cyane kuri electrode nziza. Ishobora kandi gukoreshwa nk'electrode mbi muri bateri zifite anode za lithium titanate.
2. Udupapuro twa nikeli (Ni): Ikoresha gusa electrodes mbi mu bikoresho bikoresha ingufu nke nka telefoni zigendanwa, tableti, na power banks.
3. Nickel yashizwemo umuringa (Ni-Cu): Yagenewe electrode mbi muri bateri z'amashanyarazi (urugero, imodoka zikoresha amashanyarazi) na bateri zigezweho, ihuza imikorere y'umuringa n'ubudahangarwa bwa nikeli.

2. Ubwoko bw'agakoresho gafatana n'agasanduku

Amasoko yo mu gihugu ashyira kole ku mabati mu byiciro hakurikijwe amabara, bigaragaza itandukaniro mu bwiza n'ikoreshwa:

1. Udupapuro tw'umukara dufataho kole: Ikoreshwa muri bateri za digitale zo mu rwego rwo hasi kugeza hagati. Imiterere yazo (ishusho ya PEN ifite urwego rwa PP rwahinduwe) ishobora kwangirika uko igihe kigenda gihita.
2. Udupapuro tw'umuhondo two gufunga: Bikunze kugaragara muri batiri zikoresha ingufu zo hagati. Nubwo byoroshye kuzifunga, igice cyazo cy’imbere kidafunze gishobora kwinjiza ubushuhe, bigatuma batiri ibyimba.
3. Udupapuro tw'umweru two gukodesha: Bikundwa cyane ku bikoresho bya elegitoroniki bigezweho, bateri zikoresha ingufu, na bateri zihendutse. Iboneka mu buryo bumwe, butatu, cyangwa butanu, kole y'umweru ifite urwego rutatu (ifite PP cores) itanga uburyo bwo gufunga neza kandi nta ngaruka zo gucikamo ibice.
4. Udupapuro tw'inyuma: Imirongo ikomeza ifatanye mu mizinga, ikaba ari myiza cyane ku miyoboro ikora mu buryo bwikora.
5. Udupapuro tw'urupapuro: Udupapuro tw’ibumba dushyizwe hagati y’amabati ya pulasitiki, dukwiriye gukoreshwa mu buryo bw’intoki cyangwa ubw’imashini.

3. Binyuze mu gupakira

1. Udupapuro tw'inyuma: Imirongo ikomeza ifatanye mu mizinga, ikaba ari myiza cyane ku miyoboro ikora mu buryo bwikora.
2. Udupapuro tw'urupapuro: Udupapuro tw’ibumba dushyizwe hagati y’amabati ya pulasitiki, dukwiriye gukoreshwa mu buryo bw’intoki cyangwa ubw’imashini.

Ibikoresho by'ingenzi n'imikorere

Imikorere ya tabs ishingiye cyane ku bikoresho biyigize:

1. Uduce tw'icyuma: Aluminiyumu (alloy ya AL1050) n'umuringa (umuringa udafite ogisijeni ya TU1) bikunzwe cyane kubera ubushobozi bwabyo bwo gutwara ibintu, ubushobozi bwo kugenda neza, no kwirinda ingese. Gushyira nikeli ku mirongo y'umuringa birinda ogisijeni kandi bikongera ubushobozi bwo gusonerwa.
2. Kole zo gufunga: Kole nyinshi zitumizwa mu Buyapani, kubera ko ibikoresho bya PP byo mu gihugu bigorwa no kuzuza ibisabwa bikomeye by’uburemere bwa molekile. Kole nziza cyane (urugero, kole z’umweru z’icyiciro cya gatatu) zirinda ubushyuhe (aho zishongesha ~ 147°C) kandi zigahinduka, bigatuma zifungwa neza hakoreshejwe filime za pulasitiki za aluminiyumu.

Inganda n'Igenzura ry'Ubuziranenge

Gukora tabs zifite imikorere yo hejuru bisaba ubushishozi:

1. Imikorere yo gushyiramo ipamba: Udupapuro tw'umuringa dupfundikiye nikeli dukoresha electroplating (ubugari bwa 1.8±0.3μm) cyangwa electroplating (ubugari bwa 1.0±0.3μm) kugira ngo dufashe neza.
2. Gukata impande: Imirongo y'icyuma ifite ubunini burenze 0.2mm isaba gukata impande kugira ngo hirindwe ibibazo byo gushyushya no kuva amazi.
3. Isuzuma rikomeye:
   1. Ibipimo byo kwibiza mu mazi bya electrolyte: Udupfunyika tugomba kugumana imbaraga zo gufunga >15N/15mm nyuma y'amasaha 24 kuri 85°C.
   2. Ibizamini byo kunama: Utwuma tugomba kwihanganira uburebure bwa 5-7 (bitewe n'ubunini) kugira ngo dukomeze mu bidukikije bitigita (urugero: imodoka zikoresha amashanyarazi).

Uburyo bwo guhuza tab

Guhuza tabs n'imirongo yo hanze bikubiyemo uburyo butandukanye:

1. Gufatana mu buryo bwa mekanike: Gucukura no gukurura bitanga uburyo buhendutse kandi bukomeye bwo guhuza ariko bisaba kugenzura neza ubugari.
2. Gushongesha: Solder ya M51 ifite ubushyuhe buke ikora ku byuma bitandukanye (urugero: umuringa na aluminiyumu) ​​ariko irahenze.
3. Gusudira hakoreshejwe ikoranabuhanga rya Ultrasonic: Uburyo bwiza bwo gukoresha bateri zikoresha ingufu, hakoreshejwe vibration nyinshi kugira ngo uhuze tab foils nto (0.01mm) nta bushyuhe bwinshi.

Umwanzuro

Utwuma dushobora kuba duto, ariko imiterere yatwo n'ubwiza bwatwo bigira ingaruka ku mikorere ya bateri yo mu gakapu. Uko umubare w'abakoresha bateri zitekanye kandi zikora neza mu modoka zikoresha amashanyarazi no mu kubika ingufu, iterambere mu bikoresho bya tabi (urugero: kole nyinshi) no mu nganda (urugero: gupakira neza) bizakomeza kuba ingenzi. Gusobanukirwa imiterere ya tabi ni ingenzi mu kunoza ubwizigirwa bwa bateri no kuramba kwayo mu buryo butandukanye.
