Passivation ya Bateri ya LiSoCl2 niyihe? Nigute ushobora kuvanaho?

Passivation muri Bateri ya Litiyumu

Passivation muri bateri ya lithium, cyane cyane abakoresha lithium thionyl chloride (LiSOCl2) chimie, bivuga ibintu bisanzwe aho firime yoroheje ikora kuri lithium anode. Iyi firime igizwe ahanini na lithium chloride (LiCl), ikomoka ku miti yibanze ya selile. Mugihe iyi passivation igaragara ishobora guhindura imikorere ya bateri, cyane cyane nyuma yigihe kirekire cyo kudakora, nayo igira uruhare runini mukuzamura ubuzima bwa bateri n'umutekano.

Imiterere ya Passivation

Muri bateri ya lithium thionyl chloride, passivation iba muburyo busanzwe bitewe nigisubizo kiri hagati ya lithium anode na thionyl chloride (SOCl2) electrolyte. Iyi reaction itanga lithium chloride (LiCl) na dioxyde de sulfure (SO2) nkibicuruzwa. Lithium chloride buhoro buhoro ikora urwego ruto, rukomeye hejuru ya lithium anode. Uru rupapuro rukora nk'imashanyarazi ikoresha amashanyarazi, ikabuza gutembera kwa ion hagati ya anode na cathode.

Inyungu za Passivation

Inzira ya passivation ntabwo yangiza rwose. Inyungu yibanze ni ukongera ubuzima bwa bateri. Mugabanye igipimo cyo kwikuramo cya batiri, igipande cya passivation cyemeza ko bateri igumana amafaranga yayo mugihe kinini cyo kubika, bigatuma bateri ya LiSOCl2 iba nziza kubisabwa aho kwizerwa kwigihe kirekire utabungabunzwe ari ngombwa, nko mubyihutirwa no kugarura imbaraga ibikoresho, igisirikare, n'ibikoresho by'ubuvuzi.

Byongeye kandi, passivation layer igira uruhare mumutekano rusange wa bateri. Irinda reaction zikabije hagati ya anode na electrolyte, zishobora gutera ubushyuhe bwinshi, guturika, ndetse no guturika mugihe gikabije.

Ibibazo bya Passivation

Nubwo inyungu zayo, passivation itera ibibazo bikomeye, cyane cyane iyo bateri isubijwe muri serivisi nyuma yigihe kirekire cyo kudakora. Imiterere yimikorere ya passivation irashobora gutuma habaho kwiyongera kwimbere, bishobora kuvamo:
Kugabanya ingufu za mbere (gutinda kwa voltage)
Kugabanya ubushobozi muri rusange
Time Igihe cyo gusubiza buhoro

Izi ngaruka zirashobora kuba ikibazo mubikoresho bisaba imbaraga nyinshi ako kanya mugihe cyo gukora, nka GPS ikurikirana, ibyuma byihutirwa byihutirwa, hamwe nibikoresho bimwe na bimwe byubuvuzi.

Gukuraho cyangwa Kugabanya Ingaruka za Passivation

1. Gushyira Umutwaro: Uburyo bumwe busanzwe bwo kugabanya ingaruka za passivation harimo gukoresha umutwaro w'amashanyarazi uciriritse kuri bateri. Uyu mutwaro ufasha 'kumena' urwego rwa passivation, cyane cyane kwemerera ion gutangira gutemba cyane mubwisanzure hagati ya electrode. Ubu buryo bukoreshwa kenshi mugihe ibikoresho byakuwe mububiko kandi bigasabwa gukora ako kanya.

2. Kwishyuza Pulse: Kubibazo bikomeye, tekinike yitwa pulse charging irashobora gukoreshwa. Ibi bikubiyemo gukoresha urukurikirane rugufi, rwihuta-rwinshi kuri bateri kugirango uhungabanye passivation igaragara cyane. Ubu buryo burashobora kuba ingirakamaro ariko bugomba gucungwa neza kugirango wirinde kwangiza bateri.

3. Gutunganya Bateri: Ibikoresho bimwe bikubiyemo uburyo bwo gutondekanya ibintu rimwe na rimwe bikoresha umutwaro kuri bateri mugihe cyo kubika. Iki gipimo cyo gukumira gifasha kugabanya ubunini bwurwego rwa passivation ikora, kwemeza ko bateri ikomeza kwitegura gukoreshwa nta kwangirika kwimikorere igaragara.

4. Ubushyuhe bukonje burashobora kugabanya umuvuduko wimiti igira uruhare muri passivation.

5. Ibikoresho byongera imiti: Bamwe mubakora bateri bongeramo imiti muri electrolyte ishobora kugabanya imikurire cyangwa ituze ryurwego rwa passivation. Izi nyongeramusaruro zagenewe kugumya guhangana imbere murwego rushobora gucungwa bitabangamiye umutekano cyangwa ubuzima bwa bateri.

Mu gusoza, mugihe passivation ishobora kubanza kugaragara nkibibi muri bateri ya lithium thionyl chloride, ni inkota y'amaharakubiri nayo itanga inyungu zikomeye. Gusobanukirwa imiterere ya passivation, ingaruka zayo, nuburyo bwo kugabanya izo ngaruka ningirakamaro mugutezimbere imikorere ya bateri mubikorwa bifatika. Tekinike nko gukoresha umutwaro, kwishyuza pulse, hamwe no gutondekanya batiri nibyingenzi mugucunga passivation, cyane cyane mubikorwa bikomeye kandi byizewe. Mugihe ikoranabuhanga rigenda ritera imbere, bitezimbere kurushaho muri chimie ya bateri na sisitemu yo gucunga biteganijwe ko bizamura imikorere ya passivation, bityo bikaguka gukoreshwa no gukora neza muri bateri ishingiye kuri lithium.
