1. Hadarin batirin lithium ion
Baturin lithium ion shine tushen wutar lantarki mai haɗari mai haɗari saboda halayen sinadarai da tsarin tsarinsa.
(1) Babban aikin sinadarai
Lithium shine babban rukunin I a cikin lokaci na biyu na tebur na lokaci-lokaci, tare da sinadarai masu aiki sosai.
(2) Yawan kuzari
Batirin lithium ion suna da takamaiman makamashi na musamman (≥ 140 Wh/kg), wanda ya ninka sau da yawa na nickel cadmium, nickel hydrogen da sauran batura na biyu.Idan zafin gudu na thermal ya faru, za a saki zafi mai zafi, wanda zai haifar da rashin lafiya cikin sauƙi.
(3) Amince da tsarin lantarki
A Organic sauran ƙarfi na Organic electrolyte tsarin shi ne hydrocarbon, tare da low bazuwar ƙarfin lantarki, sauki hadawan abu da iskar shaka da flammable ƙarfi;Idan ya zube, baturin zai kama wuta, har ma ya kone ya fashe.
(4) Babban yuwuwar illolin illa
A cikin tsarin amfani na yau da kullun na batirin lithium ion, ingantaccen sinadari mai kyau na musayar juna tsakanin makamashin lantarki da makamashin sinadarai yana faruwa a cikinsa.Koyaya, a ƙarƙashin wasu sharuɗɗa, kamar cajin da ya wuce kima, sama da caji ko kan aiki na yanzu, yana da sauƙi don haifar da halayen sinadarai a cikin baturi;Lokacin da abin da ya faru na gefe ya tsananta, zai yi matukar tasiri ga aiki da rayuwar baturin, kuma yana iya samar da iskar gas mai yawa, wanda zai haifar da fashewa da wuta bayan matsin lamba a cikin baturin ya karu da sauri, yana haifar da matsalolin tsaro.
(5) Tsarin kayan lantarki ba shi da kwanciyar hankali
Yawan cajin baturi na lithium ion baturi zai canza tsarin kayan aikin cathode kuma ya sa kayan suyi tasiri mai karfi na oxyidation, don haka mai narkewa a cikin electrolyte zai sami karfi mai karfi;Kuma wannan tasirin ba zai iya jurewa ba.Idan zafin da abin ya haifar ya taru, za a iya samun haɗarin haifar da guduwar thermal.
2. Binciken matsalolin aminci na samfuran batirin lithium ion
Bayan shekaru 30 na ci gaban masana'antu, samfuran batirin lithium-ion sun sami babban ci gaba a fasahar aminci, yadda ya kamata suna sarrafa abubuwan da ke faruwa na gefe a cikin baturin, kuma sun tabbatar da amincin baturin.Koyaya, yayin da ake amfani da batir lithium ion da yawa kuma yawan kuzarin su yana da girma kuma yana da girma, har yanzu akwai abubuwa da yawa kamar raunin fashewa ko tunawa da samfur saboda yuwuwar haɗarin aminci a cikin 'yan shekarun nan.Mun kammala da cewa manyan dalilan matsalolin amincin samfuran batirin lithium-ion sune kamar haka:
(1) Matsala mai mahimmanci
Abubuwan da aka yi amfani da su don wutar lantarki sun haɗa da kayan aiki masu kyau, kayan aiki mara kyau, diaphragms, electrolytes da harsashi, da dai sauransu Zaɓin kayan aiki da daidaitawa na tsarin haɗin gwiwar yana ƙayyade aikin aminci na wutar lantarki.Lokacin zabar kayan aiki masu kyau da mara kyau da kayan aikin diaphragm, masana'anta ba su gudanar da wani ƙima akan halaye da daidaitawar albarkatun ƙasa ba, wanda ya haifar da ƙarancin haihuwa a cikin amincin tantanin halitta.
(2) Matsalolin tsarin samarwa
Ba a gwada albarkatun tantanin halitta sosai ba, kuma yanayin samarwa ba shi da kyau, yana haifar da ƙazanta a cikin samarwa, wanda ba kawai cutarwa ga ƙarfin baturi ba, har ma yana da tasiri mai yawa akan amincin baturi;Bugu da ƙari, idan an haɗa ruwa da yawa a cikin electrolyte, halayen gefe na iya faruwa kuma suna ƙara matsa lamba na ciki na baturi, wanda zai shafi aminci;Saboda ƙayyadaddun matakin tsarin samarwa, yayin samar da wutar lantarki, samfurin ba zai iya cimma daidaito mai kyau ba, kamar ƙarancin flatness na matrix electrode, fadowa daga cikin kayan lantarki mai aiki, haɗuwa da sauran ƙazanta a cikin. abu mai aiki, rashin tsaro waldi na lantarki lug, rashin kwanciyar hankali zafin waldi, burrs a gefen ɓangaren lantarki, da rashin amfani da tef ɗin insulating a cikin mahimman sassan, wanda zai iya yin illa ga lafiyar wutar lantarki. .
(3) Lalacewar ƙirar ƙirar wutar lantarki tana rage aikin aminci
Dangane da ƙirar tsari, yawancin mahimman abubuwan da ke da tasiri akan aminci ba su kula da masana'anta ba.Alal misali, babu wani tef mai rufewa a mahimman sassa, babu wani gefe ko ƙarancin ƙima da aka bari a cikin ƙirar diaphragm, ƙirar ƙarfin ƙarfin ƙarfin lantarki da na'urori masu mahimmanci ba su da ma'ana, ƙirar yanki na yanki mai aiki mai kyau da mara kyau. abubuwa ba su da ma'ana, kuma zane na tsawon lugga ba shi da ma'ana, wanda zai iya sanya haɗarin ɓoye ga amincin baturi.Bugu da kari, a cikin tsarin samar da tantanin halitta, wasu masana'antun tantanin halitta suna ƙoƙarin adanawa da damfara albarkatun ƙasa don adana farashi da haɓaka aiki, kamar rage yankin diaphragm, rage foil ɗin jan ƙarfe, foil na aluminum, da rashin amfani da bawul ɗin taimako na matsa lamba ko tef mai rufewa, wanda zai rage amincin baturi.
(4) Yawan kuzari da yawa
A halin yanzu, kasuwa tana neman samfuran batir tare da babban iko.Don haɓaka gasa na samfuran, masana'antun suna ci gaba da haɓaka ƙayyadaddun ƙarfi na batir lithium ion, wanda ke haɓaka haɗarin batura.
