Kuki bateri ya lithium ikoresha aluminium nkibishishwa?

Impamvu nyamukuru zituma bateri ya lithium yo gukoresha ibishishwa bya aluminiyumu irashobora gusesengurwa ku buryo burambuye uhereye ku ngingo zikurikira, arizo zoroheje, irwanya ruswa, itwara neza, imikorere myiza yo gutunganya, igiciro gito, imikorere myiza yo gukwirakwiza ubushyuhe, nibindi.

1. Umucyo

• Ubucucike buke: Ubucucike bwa aluminiyumu bugera kuri 2,7 g / cm³, buri munsi cyane ugereranije n’ibyuma, bingana na 7.8 g / cm³. Mubikoresho bya elegitoronike bikurikirana ingufu nyinshi kandi zoroheje, nka terefone zigendanwa, mudasobwa zigendanwa, hamwe n’imodoka zikoresha amashanyarazi, ibishishwa bya aluminiyumu birashobora kugabanya neza uburemere rusange no kunoza kwihangana.

2. Kurwanya ruswa

• Guhuza n’ibidukikije bikoresha ingufu nyinshi: Umuvuduko wakazi wa batiri ya lithium ibikoresho byiza bya electrode, nkibikoresho bya ternary na lithium cobalt oxyde, ni hejuru (3.0-4.5V). Kuri ubwo bushobozi, aluminiyumu izakora firime yuzuye ya aluminium (Al₂O₃) hejuru ya passiwasi kugirango irinde kwangirika. Ibyuma byangirika byoroshye na electrolyte munsi yumuvuduko mwinshi, bikaviramo imikorere ya bateri kwangirika cyangwa kumeneka.

• Guhuza electrolyte: Aluminium ifite imiti ihamye kuri electrolytike kama, nka LiPF₆, kandi ntabwo ikunda kubyitwaramo mugihe kirekire.

3. Imyitwarire nigishushanyo mbonera

• Ihuriro ryabakusanyirizo ba none: Aluminium nibikoresho byatoranijwe kubintu byiza bya electrode nziza (nka aluminium foil). Igikonoshwa cya aluminiyumu gishobora guhuzwa neza na electrode nziza, koroshya imiterere yimbere, kugabanya guhangana, no kunoza ingufu zo kohereza ingufu.

• Igikonoshwa gisabwa: Mubishushanyo bimwe na bimwe bya batiri, igikonoshwa cya aluminium ni igice cyinzira igezweho, nka bateri ya silindrike, ifite ibikorwa byogukingira no kurinda.

4. Gutunganya imikorere

• Guhindagurika bihebuje: Aluminium iroroshye gushyirwaho kashe no kurambura, kandi irakwiriye kubyara umusaruro munini wimiterere igoye, nka firime ya aluminium-plastike ya bateri kare kandi yoroshye-ipakira. Ibishishwa by'ibyuma biragoye kubitunganya kandi bifite ibiciro byinshi.

• Ingwate yo gufunga: Tekinoroji ya Aluminium yo gusudira irakuze, nko gusudira laser, ishobora gufunga neza electrolyte, ikarinda ubushuhe na ogisijeni gutera, kandi ikongerera igihe cya batiri.

5. Gucunga ubushyuhe

• Gukwirakwiza ubushyuhe bwinshi: Ubushyuhe bwumuriro wa aluminium (hafi 237 W / m · K) buri hejuru cyane ugereranije nicyuma (hafi 50 W / m · K), ifasha bateri gusohora ubushyuhe vuba mugihe ikora kandi bikagabanya ibyago byo guhunga ubushyuhe.

6. Igiciro nubukungu

• Amafaranga make yo gutunganya no gutunganya: Igiciro fatizo cya aluminiyumu iringaniye, kandi ingufu zitunganyirizwa ni nke, zikwiranye n’umusaruro munini. Ibinyuranye, ibikoresho nkibyuma bidafite ingese bihenze cyane.

7. Igishushanyo mbonera cy'umutekano

• Uburyo bwo gutabara igitutu: Igikonoshwa cya Aluminiyumu kirashobora kurekura umuvuduko wimbere kandi kikirinda guturika mugihe habaye amafaranga arenze urugero cyangwa guhunga ubushyuhe mugushiraho indangagaciro z'umutekano, nka CID flip imiterere ya bateri ya silindrike.

8. Imikorere yinganda nubuziranenge

Ibishishwa bya Aluminiyumu byakiriwe cyane kuva mu minsi ya mbere yo gucuruza batiri ya lithium, nka bateri 18650 yatangijwe na Sony mu 1991, ikora urwego rukuze rukuze n’inganda za tekiniki, bikomeza gushimangira umwanya wacyo rusange.

Hama hariho ibintu bidasanzwe. Mubintu bimwe bidasanzwe, ibyuma bikoreshwa nabyo:

Mubihe bimwe na bimwe bifite imbaraga zingirakamaro cyane zisabwa, nka bateri zimwe zingufu cyangwa ibidukikije bikabije, ibishishwa byuma bya nikel birashobora gukoreshwa, ariko ikiguzi cyongerewe uburemere nigiciro.

Umwanzuro

Igikonoshwa cya aluminiyumu cyahindutse icyifuzo cyiza cya batiri ya lithium bitewe nibyiza byabo byuzuye nkuburemere bworoshye, kurwanya ruswa, gutwara neza, gutunganya byoroshye, gukwirakwiza ubushyuhe bwiza nigiciro gito, kuringaniza neza imikorere, umutekano nibisabwa mubukungu.
