Tun shigowar kasuwa.batirin lithiuman yi amfani da su sosai don fa'idodin su kamar tsawon rai, babban takamaiman iya aiki, kuma babu tasirin ƙwaƙwalwar ajiya. Lokacin amfani da ƙananan zafin jiki, baturan lithium-ion suna da matsaloli kamar ƙananan ƙarfi, raguwa mai tsanani, rashin aikin sake zagayowar, bayyananniyar hazo lithium, da shigar lithium mara kyau da cirewa. Koyaya, yayin da filin aikace-aikacen ke ci gaba da faɗaɗa, matsalolin da rashin ƙarancin zafi na batir lithium-ion ke kawowa suna ƙara fitowa fili. Bari mu bincika dalilai kuma mu bayyana yadda ake kula da batir lithium daidai a cikin hunturu?
Tattaunawa kan abubuwan da ke shafar ƙarancin aikin batirin lithium
1. Tasirin lantarki
Electrolyte yana da mafi girman tasiri akan aikin ƙarancin zafin jiki nabatirin lithium. Abun da ke ciki da kaddarorin physicochemical na electrolyte suna da tasiri mai mahimmanci akan ƙarancin yanayin zafi na baturi. Matsalolin da batirin ke fuskanta a ƙananan zafin jiki shi ne dankon electrolyte zai ƙaru, saurin tafiyar da ion zai ragu, wanda zai haifar da rashin daidaituwa a cikin gudun hijirar lantarki na kewayen waje, don haka baturin zai zama polarized sosai kuma karfin caji da fitarwa zai ragu sosai. Musamman lokacin da ake caji a ƙananan zafin jiki, ions lithium na iya yin sauƙi a samar da lithium dendrites a saman madaidaicin lantarki, yana haifar da gazawar baturi.
2. Tasirin kayan lantarki mara kyau
- Ƙarƙashin baturi yana da mahimmanci yayin caji mai ƙarancin zafi da caji, kuma ana ajiye adadi mai yawa na lithium na ƙarfe a saman madaidaicin lantarki. Samfurin amsawar lithium da electrolyte gabaɗaya baya aiki;
- Daga ra'ayi na thermodynamic, electrolyte ya ƙunshi babban adadin ƙungiyoyin polar irin su CO da CN, wanda zai iya amsawa tare da kayan lantarki mara kyau, kuma fim din SEI da aka kafa ya fi sauƙi ga ƙananan zafin jiki;
- Yana da wahala ga carbon negative electrodes su saka lithium a ƙananan yanayin zafi, kuma akwai asymmetry a caji da fitarwa.
Yadda za a bi da batirin lithium daidai a cikin hunturu?
1. Kada a yi amfani da baturan lithium a cikin ƙananan yanayin zafi
Zazzabi yana da babban tasiri akan batir lithium. Ƙananan zafin jiki, ƙananan ayyukan batir lithium, wanda kai tsaye yana haifar da raguwa mai yawa a cikin caji da haɓakar caji. Gabaɗaya magana, zafin aiki nabatirin lithiumyana tsakanin -20 digiri da 60 digiri.
Lokacin da zafin jiki ya kasa 0 ℃, yi hankali kada ku yi caji a waje. Za mu iya ɗaukar baturi a gida don yin caji (bayanin kula, tabbatar da nisantar kayan da za a iya ƙonewa !!!). Lokacin da zafin jiki ya kasa -20 ℃, baturin zai shiga yanayin barci ta atomatik kuma ba za a iya amfani dashi akai-akai ba.
Don haka, musamman ga masu amfani da shi a wuraren sanyi a arewa, idan da gaske babu yanayin caji na cikin gida, sai a yi amfani da ragowar zafin lokacin da batirin ya kashe, sannan a yi cajin shi a rana nan da nan bayan yin parking don ƙara adadin caji da kuma guje wa hazo na lithium.
2. Haɓaka dabi'ar caji yayin amfani da ita
A cikin hunturu, lokacin da ƙarfin baturi ya yi ƙasa sosai, dole ne mu yi cajin shi cikin lokaci kuma mu haɓaka kyawawan halaye na caji yayin amfani da shi. Ka tuna, kar a taɓa ƙididdige ƙarfin baturi a cikin hunturu daidai da rayuwar baturi na yau da kullun.
A cikin hunturu, aikin nabatirin lithiumyana raguwa, wanda zai iya haifar da zubar da ruwa da yawa a sauƙaƙe, wanda zai iya shafar rayuwar batir ko ma haifar da haɗarin konewa. Sabili da haka, a cikin hunturu, ya kamata ku kula da caji a cikin ƙaramin fitarwa da ƙananan caji. Musamman, kar a ajiye motar na dogon lokaci yayin caji don guje wa yin caji.
3.Kada ka nisanci lokacin caji. Ka tuna kada ku yi caji na dogon lokaci.
Kada ku yi cajin abin hawa na dogon lokaci don dacewa. Cire shi kawai lokacin da ya cika caji. Yanayin caji a cikin hunturu kada ya zama ƙasa da 0 ℃. Lokacin caji, kar a bar wuri mai nisa don hana aukuwar gaggawa kuma a magance su cikin lokaci.
4. Yi amfani da keɓaɓɓen caja don batir lithium lokacin caji.
Kasuwar cike take da caja marasa inganci. Yin amfani da caja marasa inganci zai haifar da lalacewar baturi har ma ya haifar da gobara. Kada ku sayi kayayyaki masu rahusa da marasa tsaro don arha, balle a yi amfani da cajar baturin gubar-acid; idan cajar ku ba za a iya amfani da ita ta al'ada ba, dakatar da amfani da shi nan da nan, kuma kada ku rasa babban hoto na ƙarami.
5. Kula da rayuwar baturi kuma maye gurbin shi cikin lokaci
Batirin lithiumsami tsawon rayuwa. Daban-daban bayanai da samfura suna da tsawon rayuwa daban-daban. Bugu da kari, saboda rashin amfani na yau da kullun, rayuwar batir ya bambanta daga ƴan watanni zuwa shekaru uku. Idan motar ta yi asarar wuta ko kuma rayuwar baturi ta yi gajere, da fatan za a tuntuɓi ma'aikatan kula da baturin lithium cikin lokaci don sarrafa ta.
6. Bar wasu iko don hunturu
Domin yin amfani da abin hawa kamar yadda aka saba a cikin bazara na shekara mai zuwa, idan ba a yi amfani da baturi na dogon lokaci ba, ku tuna da cajin shi zuwa 50% -80%, cire shi daga motar don ajiya, kuma cajin shi akai-akai, kusan sau ɗaya a wata. Lura: Dole ne a adana baturin a busasshen wuri.
7. Sanya baturin daidai
Kada a nutsar da baturin cikin ruwa ko sanya shi jika; kar a tara baturin fiye da yadudduka 7, ko juya alkiblar baturin.

A -20 ℃, da fitarwa damar baturi lithium-ion ne kawai game da 31.5% na cewa a dakin zafin jiki. Yanayin zafin aiki na batura lithium-ion na gargajiya yana tsakanin -20 da +55 ℃. Koyaya, a fagen sararin samaniya, masana'antar soja, motocin lantarki, da sauransu, ana buƙatar batura suyi aiki akai-akai a -40 ℃. Don haka, haɓaka ƙarancin zafin batir na lithium-ion yana da mahimmanci. Hakika, dabaturi lithiummasana'antu na ci gaba da haɓakawa, kuma masana kimiyya suna ci gaba da nazarin batir lithium waɗanda za a iya amfani da su a cikin ƙananan yanayin zafi don magance matsaloli ga abokan ciniki.
Heltec Energy shine amintaccen abokin tarayya a masana'antar fakitin baturi. Tare da mu mai da hankali kan bincike da haɓakawa, tare da cikakken kewayon kayan aikin baturi, muna ba da mafita guda ɗaya don saduwa da buƙatun ci gaba na masana'antu. Za mu iya keɓance batirin lithium don yanayi daban-daban don abokan ciniki. Idan kana buƙatar haɓaka baturin lithium ɗinka ko saita allon kariya, da fatan za a tuntuɓe mu.
Idan kuna da wasu tambayoyi ko kuna son ƙarin koyo, da fatan za ku yi jinkirikai gare mu.
