Batiri
Batiri ya Litiyumu ni ubwoko bwa bateri ikoresha ibyuma bya lithium cyangwa lithium alloy nkibikoresho bya electrode mbi kandi ikoresha igisubizo cya electrolyte idafite amazi.Bateri ya mbere yatanzwe ya lithium yavuye mubuhanga bukomeye Edison.

Kuberako imiti yimiti ya lithium ikora cyane, gutunganya, kubika no gukoresha ibyuma bya lithium bifite byinshi bisabwa kubidukikije.Kubwibyo, bateri ya lithium ntabwo imaze igihe kinini ikoreshwa.

Hamwe niterambere ryikoranabuhanga rya mikorobe mu kinyejana cya makumyabiri, ibikoresho bya miniaturizasi bigenda byiyongera umunsi ku munsi, ibyo bikaba bitanga ibisabwa cyane kugirango amashanyarazi abeho.Batteri ya Litiyumu noneho yinjiye murwego runini rufatika.

Yakoreshejwe bwa mbere muri pacemakers yumutima.Kuberako igipimo cyo kwisohora cya batiri ya lithium kiri hasi cyane, voltage yo gusohora irakomeye.Bituma bishoboka gushira pacemaker mumubiri wumuntu igihe kirekire.

Batteri ya Litiyumu muri rusange ifite voltage nominal irenga 3.0 volt kandi irakwiriye cyane kubitanga amashanyarazi.Batteri ya dioxyde de Manganese ikoreshwa cyane muri mudasobwa, kubara, kamera, n'amasaha.

Kugirango utezimbere ubwoko butandukanye nibikorwa byiza, ibikoresho bitandukanye byarigishijwe.Hanyuma ukore ibicuruzwa nka mbere.Kurugero, bateri ya lithium sulfur dioxyde na batiri ya lithium thionyl chloride iratandukanye cyane.Ibikoresho byabo byiza bikora nabyo birashobora gukemura electrolyte.Iyi miterere irahari gusa muri sisitemu idafite amashanyarazi.Kubwibyo, ubushakashatsi bwa bateri ya lithium nabwo bwateje imbere iterambere ryimyumvire yamashanyarazi ya sisitemu idafite amazi.Usibye gukoresha imiti itandukanye idafite amazi, hakozwe kandi ubushakashatsi kuri bateri ya polymer thin-firime.

Mu 1992, Sony yateje imbere bateri ya lithium-ion.Porogaramu ifatika igabanya cyane uburemere nubunini bwibikoresho bya elegitoroniki bigendanwa nka terefone igendanwa na mudasobwa ya ikaye.Igihe cyo gukoresha cyongerewe cyane.Kubera ko bateri ya lithium-ion idafite chromium iremereye cyane, ugereranije na bateri ya nikel-chromium, umwanda ku bidukikije uragabanuka cyane.

Uburyo 3. Nyamuneka koresha charger yumwimerere cyangwa charger izwi.Kuri bateri ya lithium, koresha charger idasanzwe kuri bateri ya lithium hanyuma ukurikize amabwiriza.Bitabaye ibyo, bateri izaba yangiritse cyangwa niyo ishobora guhura n'ingaruka.
Uburyo 4. Bateri nshya yaguzwe ni lithium ion, kubwibyo inshuro 3 kugeza kuri 5 yambere yo kwishyuza byitwa igihe cyo guhindura, kandi igomba kwishyurwa amasaha arenga 14 kugirango ibikorwa bya ioni ya lithium bikore neza.Batteri ya Litiyumu-ion ntabwo igira ingaruka zo kwibuka, ariko ifite inertness ikomeye.Bagomba gukora neza kugirango barebe imikorere myiza mubisabwa ejo hazaza.
Uburyo 5. Batiri ya lithium-ion igomba gukoresha charger idasanzwe, bitabaye ibyo ntishobora kugera kumyuzure kandi ikagira ingaruka kumikorere yayo.Nyuma yo kwishyuza, irinde kuyishyira kuri charger mugihe cyamasaha arenga 12, kandi utandukanye bateri nibicuruzwa bya elegitoroniki bigendanwa mugihe bidakoreshejwe igihe kinini.

Batiri ya Litiyumu - koresha
Hamwe niterambere ryikoranabuhanga rya mikorobe mu kinyejana cya makumyabiri, ibikoresho bya miniaturizasi bigenda byiyongera umunsi ku munsi, ibyo bikaba bitanga ibisabwa cyane kugirango amashanyarazi abeho.Batteri ya Litiyumu noneho yinjiye murwego runini rufatika.
Yakoreshejwe bwa mbere muri pacemakers yumutima.Kuberako igipimo cyo kwisohora cya batiri ya lithium kiri hasi cyane, voltage yo gusohora irakomeye.Bituma bishoboka gushira pacemaker mumubiri wumuntu igihe kirekire.
Batteri ya Litiyumu muri rusange ifite voltage nominal irenga 3.0 volt kandi irakwiriye cyane kubitanga amashanyarazi.Batteri ya dioxyde de Manganese ikoreshwa cyane muri mudasobwa, kubara, kamera, n'amasaha.

Urugero rwo gusaba
1. Hariho paki nyinshi za batiri nkizisimbuza gusana paki ya batiri: nkibikoreshwa muri mudasobwa ya ikaye.Nyuma yo gusana, usanga iyo paki ya batiri yangiritse, bateri imwe yonyine ifite ibibazo.Irashobora gusimburwa na bateri imwe ya selile ikwiye.
2. Gukora itara rike cyane-ryaka cyane Umwanditsi yigeze gukoresha bateri imwe ya 3.6V1.6AH ya litiro hamwe na tari yera yera-yaka cyane itanga urumuri rwo gukora urumuri ruto, rworoshye gukoresha, rworoshye kandi rwiza.Kandi kubera ubushobozi bwa bateri nini, irashobora gukoreshwa mugice cyisaha buri joro ugereranije, kandi imaze amezi arenga abiri idakoreshwa.
3. Ubundi buryo bwo gutanga amashanyarazi 3V

Kuberako ingufu za batiri ya lithium ya selile imwe ni 3.6V.Kubwibyo, bateri imwe ya lithium irashobora gusimbuza bateri ebyiri zisanzwe kugirango itange ingufu mubikoresho bito byo murugo nka radio, kugenda, kamera, nibindi, ntabwo byoroshye muburemere gusa, ariko kandi bimara igihe kirekire.

Litiyumu-ion ya batiri anode ibikoresho - lithium titanate

Irashobora guhuzwa na lithium manganate, ibikoresho bya ternary cyangwa fosifate ya lithium fer nibindi bikoresho byiza kugirango ikore bateri ya kabiri ya litiro 2.4V cyangwa 1.9V.Byongeye kandi, irashobora kandi gukoreshwa nka electrode nziza kugirango ikore bateri ya litiro 1.5V hamwe na lithium yicyuma cyangwa lithium alloy itari nziza ya electrode ya kabiri.

Kubera umutekano mwinshi, ituze ryinshi, kuramba hamwe nicyatsi kiranga lithium titanate.Turashobora guhanura ko ibikoresho bya lithium titanate bizahinduka ibikoresho bibi bya electrode yibisekuru bishya bya bateri ya lithium ion mumyaka 2-3 kandi bizakoreshwa cyane mumodoka nshya, moto yamashanyarazi nibisaba umutekano muke, umutekano muke hamwe nigihe kirekire.Umwanya wo gusaba.Umuvuduko ukoreshwa wa batiri ya lithium titanate ni 2.4V, voltage ndende ni 3.0V, naho amashanyarazi agera kuri 2C.

Litiyumu titanate igizwe na batiri
Electrode nziza: lithium fer fosifate, lithium manganate cyangwa ibikoresho bya ternary, lithium nikel manganate.
Electrode mbi: ibikoresho bya lithium.
Inzitizi: Inzitizi ya batiri ya lithium iriho hamwe na karubone nka electrode mbi.
Electrolyte: Litiyumu ya batiri electrolyte hamwe na karubone nka electrode mbi.
Ikarita ya Batiri: Litiyumu ya batiri hamwe na karubone nka electrode mbi.

Ibyiza bya bateri ya lithium titanate: guhitamo ibinyabiziga byamashanyarazi kugirango bisimbuze ibinyabiziga bya lisansi nibyiza guhitamo gukemura ibibazo byangiza ibidukikije mumijyi.Muri byo, bateri za lithium-ion zikurura abashakashatsi.Kugirango wuzuze ibisabwa ibinyabiziga byamashanyarazi kuri bateri yumuriro wa lithium-ion, ubushakashatsi niterambere. Ibikoresho bibi bifite umutekano mwinshi, imikorere myiza no kuramba ni ahantu hashyushye nibibazo.

Ubucuruzi bwa lithium-ion ya electrode mbi ikoresha cyane cyane ibikoresho bya karubone, ariko haracyari imbogamizi mugukoresha bateri ya lithium ukoresheje karubone nka electrode mbi:
1. Litiyumu dendrite igwa byoroshye mugihe cyo kwishyuza birenze urugero, bikaviramo umuzunguruko muto wa bateri kandi bikagira ingaruka kumikorere yumutekano wa batiri ya lithium;
2. Biroroshye gukora firime ya SEI, bivamo kwishyurwa kwambere no gusohora imbaraga nubushobozi bunini budasubirwaho;
3. Nukuvuga ko imbaraga za platifike yibikoresho bya karubone biri hasi (hafi ya lithium yicyuma), kandi biroroshye gutera kubora kwa electrolyte, bizana umutekano muke.
4. Muburyo bwo kwinjiza lithium ion no kuyikuramo, ingano irahinduka cyane, kandi guhagarara kwizunguruka ni bibi.

Ugereranije nibikoresho bya karubone, Li4Ti5012 yo mu bwoko bwa spinel ifite ibyiza byingenzi:
1. Nibikoresho bya zeru kandi bifite imikorere myiza yo kuzenguruka;
2. Umuvuduko w'amashanyarazi uhagaze neza, kandi electrolyte ntizangirika, bizamura imikorere yumutekano wa bateri ya lithium;
3. Ugereranije nibikoresho bya karubone, lithium titanate ifite coefficente ya lithium ion yo gukwirakwiza (2 * 10-8cm2 / s), kandi irashobora kwishyurwa no gusohora ku kigero cyo hejuru.
4. Ubushobozi bwa lithium titanate burenze ubw'icyuma cyiza cya lithium, kandi ntabwo byoroshye kubyara lithium dendrite, itanga umusingi wo kurinda umutekano wa bateri ya lithium.

kubungabunga umuzenguruko
Igizwe na tristoriste ebyiri zo murwego hamwe no kubungabunga ibikoresho byahujwe S-8232.Umuyoboro urenze urugero FET2 hamwe numuyoboro urenze urugero FET1 uhujwe mukurikirane kumuzunguruko, kandi voltage ya bateri irakurikiranwa kandi ikagenzurwa no kubungabunga IC.Iyo ingufu za bateri zazamutse zigera kuri 4.2V, umuyoboro urenze urugero FET1 urazimya, kandi kwishyurwa birarangiye.Kugirango wirinde gukora nabi, ubushobozi bwo gutinda bwongerwaho muri rusange.Iyo bateri iri mumasohoro, ingufu za bateri ziramanuka kugera kuri 2.55.
