Intangiriro ：
Kuva yinjira ku isoko,bateri ya lithiumByakoreshejwe cyane kubwinyungu zabo nkubuzima burebure, ubushobozi bunini bwihariye, kandi nta ngaruka zo kwibuka. Iyo ikoreshejwe mubushyuhe buke, bateri ya lithium-ion ifite ibibazo nkubushobozi buke, kwiyongera cyane, imikorere mibi yikigereranyo, imvura igaragara ya lithium, hamwe no gushyiramo lithium itaringanijwe. Nyamara, mugihe umurima wo gusaba ukomeje kwaguka, inzitizi zizanwa nubushyuhe buke bwubushyuhe bwa bateri ya lithium-ion iragenda igaragara cyane. Reka dusuzume impamvu kandi dusobanure uburyo bwo gufata neza bateri ya lithium mugihe cy'itumba?
Ikiganiro kubintu bigira ingaruka kumikorere yubushyuhe buke bwa bateri ya lithium
1. Ingaruka ya electrolyte
Electrolyte ifite ingaruka zikomeye kumikorere yubushyuhe buke bwabateri ya lithium. Ibigize hamwe na fiziki ya chimique ya electrolyte bigira ingaruka zikomeye kumikorere yubushyuhe buke bwa bateri. Ikibazo gihura na cycle ya bateri ku bushyuhe buke ni uko ubwiza bwa electrolyte bwiyongera, umuvuduko wo gutwara ion uzagabanuka, bikavamo kudahuza umuvuduko wo kwimuka kwa elegitoronike w’umuzunguruko wo hanze, bityo bateri ikazaba polarize cyane kandi ubushobozi bwo kwishyuza no gusohora bikagabanuka cyane. Cyane cyane iyo ushizemo ubushyuhe buke, ion ya lithium irashobora gukora byoroshye dendrite ya lithium hejuru ya electrode mbi, bigatuma bateri yananirana.
2. Ingaruka yibikoresho bya electrode mbi
- Amashanyarazi ya batiri arakomeye mugihe cy'ubushyuhe buke bwo kwishyuza no gusohora, kandi umubare munini wa lithium metallic ubikwa hejuru ya electrode mbi. Igicuruzwa cya reaction ya lithium metallic na electrolyte muri rusange ntabwo ikora;
- Duhereye kuri termodinamike, electrolyte irimo umubare munini wamatsinda ya polar nka CO na CN, ashobora kubyitwaramo nibikoresho bibi bya electrode, kandi film ya SEI yashizweho irashobora kwibasirwa nubushyuhe buke;
- Biragoye kuri electrode mbi ya karubone gushira lithium mubushyuhe buke, kandi hariho asimmetrie mukwishyuza no gusohora.
Nigute ushobora gufata bateri ya lithium neza mugihe cy'itumba?
1. Ntukoreshe bateri ya lithium mubushyuhe buke
Ubushyuhe bugira ingaruka zikomeye kuri bateri ya lithium. Ubushyuhe buke, niko ibikorwa bya batiri ya lithium bigabanuka, biganisha ku kugabanuka gukabije kwishyurwa no gusohora neza. Muri rusange, ubushyuhe bwo gukora bwabateri ya lithiumni hagati ya dogere -20 na dogere 60.
Iyo ubushyuhe buri munsi ya 0 ℃, witondere kutishyuza hanze. Turashobora gufata bateri mumazu kugirango tuyishyure (icyitonderwa, menya neza ko wirinda ibikoresho byaka !!!). Iyo ubushyuhe buri munsi -20 ℃, bateri izahita yinjira muburyo budasinziriye kandi ntishobora gukoreshwa mubisanzwe.
Kubwibyo, ni cyane cyane kubakoresha ahantu hakonje mumajyaruguru, niba mubyukuri nta miterere yo kwishyiriraho mu nzu, koresha neza ubushyuhe busigaye mugihe bateri isohotse, hanyuma uyishyire ku zuba ako kanya nyuma yo guhagarara kugirango wongere umubare wumuriro kandi wirinde kugwa kwa lithium.
2. Teza imbere ingeso yo kwishyuza nkuko uyikoresha
Mu gihe cy'itumba, iyo ingufu za bateri ziri hasi cyane, tugomba kuyishyuza mugihe kandi tugateza imbere ingeso nziza yo kwishyuza nkuko ubikoresha. Wibuke, ntuzigere ugereranya ingufu za bateri mugihe cyimbeho ukurikije ubuzima busanzwe bwa bateri.
Mu gihe c'itumba, ibikorwa byabateri ya lithiumigabanuka, ishobora gutera byoroshye gusohora cyane no kwishyurwa birenze, bishobora kugira ingaruka kubuzima bwa bateri cyangwa bigatera impanuka zo gutwikwa. Kubwibyo, mugihe cy'itumba, ugomba kwitondera cyane kwishyuza muburyo buke kandi muburyo buke. By'umwihariko, ntugahagarike ikinyabiziga igihe kinini mugihe wishyuza kugirango wirinde kwishyuza birenze.
3. Ntugume kure mugihe urimo kwishyuza. Wibuke kutishyuza igihe kirekire.
Ntukishyure imodoka igihe kirekire kugirango byorohe. Kuramo gusa mugihe byuzuye. Ibidukikije byishyurwa mugihe cyitumba ntibigomba kuba munsi ya 0 ℃. Mugihe cyo kwishyuza, ntugasige kure cyane kugirango wirinde ibyihutirwa kandi ubikemure mugihe gikwiye.
4. Koresha charger yabugenewe kuri bateri ya lithium mugihe urimo kwishyuza.
Isoko ryuzuyemo charger zujuje ubuziranenge. Gukoresha charger zidafite ubuziranenge bizatera kwangirika kwa batiri ndetse binatera umuriro. Ntugure ibicuruzwa bidahenze kandi bidafite ingwate kubihendutse, kereka niba ukoresha amashanyarazi ya aside-aside; niba charger yawe idashobora gukoreshwa mubisanzwe, hagarika kuyikoresha ako kanya, kandi ntutakaze ishusho nini kuri nto.
5. Witondere ubuzima bwa bateri hanyuma uyisimbuze mugihe
Batteri ya Litiyumukugira ubuzima bwawe bwose. Ibisobanuro bitandukanye hamwe na moderi bifite ubuzima butandukanye. Mubyongeyeho, kubera imikoreshereze idahwitse ya buri munsi, ubuzima bwa bateri buva mumezi make kugeza kumyaka itatu. Niba imodoka itakaje ingufu cyangwa ubuzima bwa bateri ni bugufi bidasanzwe, nyamuneka hamagara abakozi bashinzwe kubungabunga batiri ya lithium mugihe kugirango uyikemure.
6. Kureka imbaraga zubukonje
Kugirango ukoreshe ibinyabiziga bisanzwe mugihe cyumwaka utaha, niba bateri idakoreshejwe igihe kinini, ibuka kuyishyuza kugeza 50% -80%, kuyikura mumodoka kugirango ibike, kandi uyishyure buri gihe, hafi rimwe mukwezi. Icyitonderwa: Batare igomba kubikwa ahantu humye.
7. Shyira bateri neza
Ntucengeze bateri mumazi cyangwa ngo itose; ntugashyire bateri kurenza ibice 7, cyangwa ngo uhindure icyerekezo cya bateri.
Umwanzuro
Kuri -20 ℃, ubushobozi bwo gusohora bateri ya lithium-ion ni hafi 31.5% gusa yubushyuhe bwicyumba. Ubushyuhe bwo gukora bwa bateri gakondo ya lithium-ion iri hagati ya -20 na + 55 ℃. Nyamara, mubijyanye nindege, inganda za gisirikare, ibinyabiziga byamashanyarazi, nibindi, bateri zisabwa gukora bisanzwe kuri -40 ℃. Kubwibyo, kuzamura ubushyuhe buke bwa bateri ya lithium-ion ningirakamaro cyane. Birumvikana koBatiriinganda zihora zitera imbere, kandi abahanga bakomeje kwiga bateri ya lithium ishobora gukoreshwa mubushyuhe buke kugirango bakemure ibibazo kubakiriya.
Ingufu za Heltec numufatanyabikorwa wawe wizewe mugukora ibicuruzwa. Hamwe no guhora twibanda kubushakashatsi niterambere, hamwe nuburyo butandukanye bwibikoresho bya batiri, dutanga igisubizo kimwe kugirango duhuze ibikenerwa ninganda. Turashobora guhitamo bateri ya lithium kubintu bitandukanye kubakiriya. Niba ukeneye kuzamura bateri ya lithium cyangwa gushiraho ikibaho cyo kurinda, nyamuneka twandikire.
Niba ufite ikibazo cyangwa ushaka kwiga byinshi, nyamuneka ntutindiganyeutugereho.
