Chiyambi:
M'nthawi yamasiku ano yachitetezo cha chilengedwe ndiukadaulo, magalimoto amagetsi akuchulukirachulukira ndipo adzalowa m'malo mwa magalimoto amtundu wamafuta mtsogolomo. Thelithiamu batirendi mtima wa galimoto yamagetsi, kupereka mphamvu yofunikira kuti galimoto yamagetsi ipite patsogolo. Moyo wautumiki ndi chitetezo cha mabatire agalimoto yamagetsi ndizovuta kwambiri kwa eni magalimoto. Komabe, nkhani ziwirizi zimagwirizana kwambiri ndi njira yoyenera yolipirira. Mabatire omwe amagwiritsidwa ntchito pamagalimoto amagetsi tsopano akuphatikiza mabatire a ternary lithium ndi lithiamu iron phosphate. Kodi njira ziwirizi zidzakhala zotani pa mabatire awiriwa? Tiyeni tikambirane pamodzi.
Mphamvu yogwiritsa ntchito ndikuyitanitsa mabatire a ternary lithiamu
1. Kuwonongeka kwa mphamvu: Nthawi iliyonse mphamvu ya batri ya ternary lithiamu ikugwiritsidwa ntchito ndikuyimbidwa kachiwiri, ndikutuluka kwakuya, komwe kungayambitse mphamvu ya ternary lithiamu batire pang'onopang'ono kuwola, nthawi yolipira ikufupikitsa, ndi kuyendetsa galimoto kutsika. Mwachitsanzo, wina wachita kuyesera. Pambuyo ternary lithiamu batire kwambiri kutulutsidwa ka 100, mphamvu amachepetsa ndi 20% ~ 30% poyerekeza ndi mtengo woyamba. Izi ndichifukwa choti kukhetsa kwakuya kumayambitsa kuwonongeka kwa zinthu za elekitirodi, kuwonongeka kwa electrolyte, ndi chitsulo cha lithiamu mpweya kumawononga kuchuluka kwa batire ndi kutulutsa, zomwe zimapangitsa kuchepa kwa mphamvu, ndipo kuwonongeka kumeneku sikungatheke.
2. Moyo wofupikitsidwa: Kutaya kwakuya kudzafulumizitsa ukalamba wa zipangizo zamkati za ternary lithiamu batire, kuchepetsa mphamvu ya batri ndi kutulutsa ntchito, kuchepetsa chiwerengero cha mkombero ndi kutulutsa, ndikufupikitsa moyo wautumiki.
3. Kuchepetsa mtengo ndi kukhetsa bwino: Kugwiritsa ntchito mphamvu ndikuyitanitsanso kudzachititsa kuti ma elekitirodi abwino ndi oipa a ternary lithiamu batire awonongeke, kuonjezera kukana kwa mkati mwa batri, kuchepetsa kuthamanga kwachangu, kuwonjezera nthawi yolipiritsa, kuchepetsa mphamvu ya batri, ndi kuchepetsa kwambiri mphamvu zomwe zingathe kutulutsidwa.
4. Kuwopsa kwachitetezo: Kutaya kwakuya kwanthawi yayitali kungayambitse mbale zamkati za ternary.lithiamu batirekufooketsa kapena kusweka, zomwe zimapangitsa kuti pakhale kuzungulira kwakanthawi mkati mwa batri komanso kuwopsa kwa moto ndi kuphulika. Kuphatikiza apo, kutulutsa kwakuya kwa batri kumawonjezera kukana kwake kwamkati, kumachepetsa kuyendetsa bwino, ndikuwonjezera kutentha kwapanthawi yolipiritsa, zomwe zingapangitse kuti batire ya ternary lithiamu iwonongeke ndikuwonongeka, komanso kupangitsa kuthawa kwamafuta, komwe kumatsogolera kuphulika ndi moto.
Batire ya Ternary lithium ndiyo batire yamagetsi yopepuka kwambiri komanso yamphamvu kwambiri, ndipo imagwiritsidwa ntchito pamagalimoto apamwamba kwambiri amagetsi. Pofuna kupewa zotsatira zoyipa za kutulutsa kwakukulu pa batri, batire ili ndi bolodi loteteza. Mphamvu ya batire ya ternary lithiamu yokhala ndi mphamvu yokwanira pafupifupi 4.2 volts. Mphamvu yamagetsi imodzi ikatsitsidwa mpaka 2.8 volts, bolodi lodzitchinjiriza lizimitsa yokha magetsi kuti batire isathe kutulutsa.
Mphamvu ya kulipiritsa mukamapita pa mabatire a ternary lithiamu
Ubwino wa kulipiritsa mukamapita ndikuti mphamvu ya batri ndi ya kuyitanitsa kocheperako komanso kutulutsa kozama, ndipo nthawi zonse imakhala ndi mphamvu yayikulu kuti ipewe zovuta zamphamvu zochepa pa batri. Kuphatikiza apo, kuyitanitsa kozama komanso kutulutsa kozama kumathanso kusunga ntchito ya ma ion a lithiamu mkati mwa ternary.lithiamu batire, imachepetsa kukalamba kwa batire, ndikuwonetsetsa kuti batire imatha kutulutsa mphamvu mokhazikika pakagwiritsidwa ntchito motsatira, komanso imatha kuwonjezera moyo wa batri. Pomaliza, kulipiritsa mukamayenda kumatha kuwonetsetsa kuti batire nthawi zonse imakhala ndi mphamvu zokwanira ndikuwonjezera kuchuluka kwa magalimoto.
Zotsatira za recharging pambuyo pa ntchito pa lithiamu iron phosphate mabatire
Kubwezeretsanso mukatha kugwiritsa ntchito ndikutulutsa kozama, komwe kudzakhalanso ndi zotsatira zoyipa pamapangidwe amkati a mabatire a lithiamu iron phosphate, kuwononga zida zamkati za batri, kufulumizitsa ukalamba wa batri, kukulitsa kukana kwamkati, kuchepetsa kuyitanitsa ndi kutulutsa mphamvu, ndikuwonjezera nthawi yolipira. Kuonjezera apo, pambuyo potulutsa kwambiri, mankhwala a batri amakula kwambiri ndipo kutentha kumawonjezeka kwambiri. Kutentha komwe kumapangidwa sikutayika munthawi yake, zomwe zitha kupangitsa kuti batire ya lithiamu iron phosphate ichuluke ndikupunduka. Batire yophulika silingapitirire kugwiritsidwa ntchito.
Zotsatira za kulipiritsa mukamapita ku lithiamu iron phosphate
Malinga ndi kuyitanitsa ndi kutulutsa kwanthawi zonse, mabatire a lithiamu iron phosphate amatha kulipiritsidwa ndikutulutsidwa nthawi zopitilira 2,000. Ngati kulipiritsa ngati mukufunikira ndikuyitanitsa mozama komanso kutulutsa kozama, moyo wautumiki wa mabatire a lithiamu iron phosphate ukhoza kukulitsidwa mpaka kufika pamlingo waukulu. Mwachitsanzo, batire lifiyamu chitsulo mankwala akhoza mlandu ndi kutulutsidwa kuchokera 65% mpaka 85% ya mphamvu, ndi mkombero mlandu ndi kumaliseche moyo akhoza kufika nthawi zoposa 30,000. Chifukwa kumaliseche osaya akhoza kukhalabe nyonga ya yogwira zinthu mkati mwa batire lifiyamu chitsulo mankwala, kuchepetsa ukalamba wa batire, ndi kuwonjezera moyo batire mpaka pazipita.
Choyipa ndichakuti batire ya lithiamu iron phosphate imakhala yosasinthasintha. Kuchapira kosaya pafupipafupi komanso kutulutsa kungayambitse vuto lalikulu pamagetsi a batire ya lithiamu iron phosphate cell. Kuchulukana kwa nthawi yayitali kumapangitsa kuti batire iwonongeke nthawi imodzi. Kunena mwachidule, pali cholakwika mumagetsi a batri pakati pa selo lililonse. Mtengo wolakwika umaposa kuchuluka kwanthawi zonse, zomwe zingakhudze magwiridwe antchito, mtunda ndi moyo wautumiki wa paketi yonse ya batri.
Mapeto
Kupyolera mu kusanthula koyerekeza pamwambapa, kuwonongeka kwa mabatire awiriwa polipira mphamvu ya batri itatha kugwiritsidwa ntchito sikungasinthe, ndipo njirayi siyoyenera. Kulipiritsa pamene mukugwiritsa ntchito ndikosavuta kwa batire, komanso kuwonongeka komwe kumachitika chifukwa chalithiamu batirendi yaying'ono, koma si njira yolondola yolipirira. Zotsatirazi zikugawana njira yoyenera yolipirira kuti muwonjezere chitetezo chakugwiritsa ntchito batri ndikuwonjezera moyo wautumiki.
1. Pewani kutulutsa kwambiri: Pamene mphamvu yamagetsi yamagetsi yamagetsi imasonyeza kuti mphamvu ya batri ndi 20 ~ 30% yotsalira, mutatha kugwiritsa ntchito galimotoyo m'chilimwe, pitani kumalo operekera kuti mulole kuti batire ikhale yoziziritsa kwa mphindi 30 mpaka ola musanapereke, zomwe zingathe kupeŵa kutentha kwa batri kuti zisapitirire kwambiri, ndipo panthawi imodzimodziyo pewani kutayika kwa zotsatira zakuya kwa batri.
2. Pewani kuchulukitsa: Mphamvu ya batri ndi 20 ~ 30% yotsala. , Zimatenga pafupifupi maola 8 ~ 10 kuti muwononge. Ndibwino kuti magetsi amatha kudulidwa pamene mphamvu imaperekedwa ku 90% malinga ndi chiwonetsero cha mita ya mphamvu, chifukwa kulipira kwa 100% kudzawonjezera kutentha kwa kutentha ndi zoopsa za chitetezo zidzawonjezeka kwambiri, kotero magetsi amatha kudulidwa pamene amaperekedwa ku 90% kuti apewe zotsatira zoipa za ndondomeko pa batri. Mabatire a Lithium iron phosphate amatha kulipiritsidwa mpaka 100%, koma ziyenera kudziwidwa kuti magetsi ayenera kuthetsedwa munthawi yake atayimitsidwa mokwanira kuti asachulukitse.
