Passivation muLithium Mabhatiri
Passivation mumabhatiri e lithium, kunyanya ayo anoshandisa lithium thionyl chloride (LiSOCl2) chemistry, inoreva chiitiko chinowanzoitika apo firimu rakatetepa rinoumba pamusoro pe lithium anode. Iyi firimu inoumbwa zvakanyanya nelithium chloride (LiCl), inogadzirwa neyekutanga kemikari kuita mukati mesero. Nepo iyi passivation layer ichigona kukanganisa mashandiro ebhatiri, kunyanya mushure menguva refu yekusaita basa, inoitawo basa rakakosha mukusimudzira sherufu yebhatiri nekuchengetedzeka.
Kuumbwa kwePassivation Layer
Mu lithium thionyl chloride mabhatiri, passivation inowanzoitika nekuda kwekuita pakati pe lithium anode uye thionyl chloride (SOCl2) electrolyte. Izvi zvinogadzira lithium chloride (LiCl) uye sulfur dioxide (SO2) sezvigadzirwa. Iyo lithium chloride zvishoma nezvishoma inoumba danda rakatetepa, rakasimba pamusoro pe lithium anode. Ichi chitubu chinoshanda sechidziviriro chemagetsi, chinotadzisa kuyerera kweiyoni pakati peanode uye cathode.
Benefits of Passivation
Iyo passivation layer haina kukanganisa zvachose. Chakanyanya kubatsirikana ndiko kukwidziridzwa kwehupenyu hwebhatiri. Nekudzikamisa chiyero chekuzviburitsa chebhatiri, iyo passivation layer inovimbisa kuti bhatiri rinochengeta chaji kwenguva yakareba yekuchengetedza, zvichiita kuti LiSOCl2 mabhatiri akanakira maapplication uko kuvimbika kwenguva refu pasina kugadzirisa kwakakosha, senge mukukurumidzira uye simba rekuchengetedza. zvekushandisa, zvechiuto, uye zvekurapa.
Uyezve, iyo passivation layer inobatsira kune kuchengetedzeka kwese kwebhatiri. Inodzivirira kuita kwakanyanya pakati peanode uye electrolyte, izvo zvinogona kutungamirira mukupisa, kuputika, kana kunyange kuputika mumamiriro ezvinhu akanyanya.
Matambudziko ePasivation
Pasinei nemabhenefiti ayo, passivation inokonzeresa matambudziko, kunyanya kana bhatiri radzoserwa kushanda mushure menguva refu yekusaita. Iyo insulating zvimiro zvepassivation layer inogona kutungamira kuwedzera kwemukati kuramba, izvo zvinogona kukonzera:
● Yakaderedzwa yekutanga voltage (voltage kunonoka)
●Kudzikira kwese
● Nguva yekupindura inononoka
Izvi zvinokonzeresa zvinogona kunetsa mumidziyo inoda simba rakawanda nekukasira payakabatidzwa, senge GPS trackers, emergency emergency transmitters, uye zvimwe zvigadzirwa zvekurapa.
Kubvisa kana Kuderedza Migumisiro yePasivation
1. Kuisa Mutoro: Imwe nzira yakajairika yekudzikisa mhedzisiro yepassivation inosanganisira kushandisa mwero wemagetsi mutoro kubhatiri. Uyu mutoro unobatsira 'kupwanya' passivation layer, zvichibvumira maion kuti atange kuyerera zvakasununguka pakati pemagetsi. Iyi nzira inowanzoshandiswa kana zvishandiso zvabviswa kunze kwekuchengetwa uye zvinofanirwa kuita nekukurumidza.
2. Pulse Charging: Kune dzimwe nyaya dzakakomba, nzira inonzi pulse charging inogona kushandiswa. Izvi zvinosanganisira kuisa akatevedzana mapfupi, epamusoro-ikozvino pulses kubhatiri kukanganisa passivation layer zvine hukasha. Iyi nzira inogona kushanda asi inofanirwa kubatwa nemazvo kudzivirira kukuvadza bhatiri.
3. Battery Conditioning: Mimwe michina inobatanidza maitiro ekugadzirisa iyo nguva nenguva inoshandisa mutoro kune bhatiri panguva yekuchengetedza. Ichi chiyero chekudzivirira chinobatsira kudzikisira ukobvu hweiyo passivation layer inoumba, kuve nechokwadi chekuti bhatiri rinoramba rakagadzirira kushandiswa pasina kukanganisa kwakanyanya kwekuita.
4. Controlled Storage Conditions: Kuchengeta mabhatiri pasi pemamiriro ezvakatipoteredza anodzorwa (optimal tembiricha uye humidity) zvinogonawo kuderedza chiyero chepassivation layer kugadzirwa. Kutonhodza tembiricha kunogona kudzikisira kuita kwekemikari inosanganisirwa mukupasa.
5. Chemical Additives: Vamwe vanogadzira bhatiri vanowedzera makemikari emakemikari kune electrolyte iyo inogona kuderedza kukura kana kugadzikana kwepasi passivation layer. Izvi zvinowedzera zvakagadzirirwa kuchengetedza kupikisa kwemukati pamazinga anogoneka pasina kukanganisa kuchengetedza kana hupenyu hwesherufu hwebhatiri.
Mukupedzisa, nepo passivation inogona kutanga kuita seyakashata mumabhatiri e lithium thionyl chloride, ipfumo rinocheka kaviri rinopawo zvakakosha mabhenefiti. Kunzwisisa hunhu hwekupasa, mhedzisiro, uye nzira dzekudzikisa izvi mhedzisiro kwakakosha pakuwedzera kuita kwemabhatiri aya mukushandisa zvinoshanda. Matekinoroji akaita sekuisa mutoro, pulse kuchaja, uye bhatiri mamiriro akakosha mukugadzirisa passivation, kunyanya mukukosha uye kuvimbika kwepamusoro maapplication. Sezvo tekinoroji ichifambira mberi, kumwe kuvandudzwa kwekemikari yebhatiri uye masisitimu ekutonga anotarisirwa kusimudzira mabatiro ekufambisa, nekudaro kuwedzera kushanda uye kushanda zvakanaka kwemabhatiri e-lithium.
