Rashin kula da zafi shine mafi munin hatsarin aminci a cikin amfani da batura lithium-ion. Yawan zafin da ba a iya sarrafawa yana faruwa ne saboda baturin lithium ion wanda a cikinsa ya lalace, ko kuma ya karye diaphragm, ko kuma saboda gajeriyar da&39;ira ta waje a wajen baturin. Ya haifar da zafi mai yawa, wanda ke haifar da zafi mai yawa, yana ƙaddamar da wani abu mai kyau da mara kyau da kuma electrolyte, yana haifar da baturin lithium-ion don hanawa da fashewa, yana barazana ga rayuka da dukiyoyin masu amfani.

Sabili da haka, ana buƙatar baturin lithium-ion gabaɗaya a cikin gano amincin batirin lithium ion, kuma ana buƙatar batirin lithium ion don wuce caji, jujjuyawa, gajeriyar kewayawa da extrusion, acupuncture, amma tare da ci gaba da haɓaka ƙarfin ƙarfin baturin lithium da ƙarfin baturi, batirin ya wuce acupuncture gwajin ya zama mai wahala kuma yana da wahala, don haka ba a aiwatar da batirin Iko.

1. Electrolytic liquid retardant electrolyte flame retardant hanya ce mai matukar tasiri don rage zafin baturi daga sarrafawa, amma waɗannan masu kashe wuta sau da yawa suna da tasiri mai tsanani akan aikin lantarki na batirin lithium-ion, don haka yana da wahala a yi amfani da shi a ainihin amfani. Don magance wannan matsala, ƙungiyar Yuqiao na Sheng Diego, California, China [1] tana adana wutar lantarki DBA (dibenzylamine) a cikin ciki na microcapsules a cikin akwati na kunshin capsule, watsawa a cikin electrolyte, ba zai tasiri aikin lantarki na baturin lithium-ion ba, amma lokacin da baturi ya lalace ta hanyar extrusion, baturin ya lalace ta hanyar extrusion. "mai guba" yana haifar da gazawar baturi, don haka yana hana faruwar zafin jiki daga sarrafawa.

Kungiyar Yuqiao ta 2018 [2] ta sake yin amfani da dabarar da ke sama, ana amfani da ethylene glycol da ethylenediamine azaman mai hana wuta, kuma an ɗora ɓangaren ciki na batirin lithium ion a cikin baturin lithium-ion ya ragu da 70% a cikin gwajin acupuncture. Mahimman rage haɗarin thermal daga sarrafa batirin lithium ion. Hanyar da aka ambata a sama ita ce lalata kai, wato, da zarar an yi amfani da wutar lantarki, duk batirin lithium-ion za a soke shi, kuma tawagar Atsuoyamada na Jami&39;ar Tokyo, Japan [3] sun ƙera wani nau&39;i na sakamako daga lithium Flame retardant electrolyte na dukiyar baturi ion, maganin wutan lantarki yana amfani da ma&39;auni mai yawa na NaN (SOF2) ko N2 (F2).

Ester TMP ya inganta ingantaccen yanayin zafi na baturin lithium-ion, wanda ya fi karfi. Bugu da kari na harshen wuta retardant ba ya shafar sake zagayowar yi na lithium ion baturi, da baturi rungumi dabi&39;ar da electrolyte za a iya stably zagaya fiye da 1000 sau (C / 5) 1200 sau a wurare dabam dabam, iya aiki kudi 95%). Ta hanyar ƙari, baturin lithium ion yana da kaddarorin wuta don hana ɗaya daga cikin hanyoyin thermal daga sarrafa batirin lithium ion, wasu kuma suna da wata hanya, suna ƙoƙarin hana faruwar gajerun da&39;irori a cikin batir lithium ion wanda tushen tushen ke haifar da shi, don haka cimma manufar ɗaukar kasan kettle.

Da kyau kawar da abin da ya faru na thermal daga sarrafawa. Dangane da baturin lithium mai ƙarfi da ake amfani da shi, yana iya fuskantar tasirin tashin hankali, Gabrielm na Laboratory National Oak Ridge na Amurka.

Fakitin batir ƙirar aminci mai zafi Ana amfani da batirin lithium mai ƙarfi sau da yawa a cikin amfani, ɗaruruwa ko ma dubban batura waɗanda suka ƙunshe a layi daya, kamar fakitin baturi na Model na Tesla daga sama da 7,000.

Abun da ke ciki na 18650, idan ɗaya daga cikin batura ya faru, yana iya yaduwa a cikin fakitin baturi, yana haifar da mummunan sakamako. Misali, a watan Janairun 2013, wani jirgin saman Japan na Boston na kasar Amurka, jirgin fasinja Boeing 787, bisa binciken Hukumar Kula da Sufuri ta Amurka, ya samu batir lithium-ion murabba&39;in 75AH a cikin fakitin baturi. Bayan asarar sarrafawa, zafin baturin da ke kusa da shi ya fita daga sarrafawa.

Bayan afkuwar lamarin, Boeing ya nemi matakan da za su kara bazuwar rashin sarrafawa a kan dukkan fakitin baturi. Don hana zafi daga kasancewa daga iko a cikin ciki na baturin lithium ion, US AllCelltechnology ya haɓaka kayan keɓewar baturi na lithium-ion wanda ya dogara da kayan canjin lokaci [5]. An cika kayan PCC tsakanin batirin lithium ion monomer, a cikin yanayin inda fakitin batirin lithium ion ke aiki da kyau, za&39;a iya watsa zafin baturin cikin sauri zuwa fakitin baturi ta cikin kayan PCC, kuma lokacin da asarar zafi na batirin lithium ion baturi, PCC kayan Ana iya narke ta cikin kayan paraffin don hana ɗaukar babban adadin zafi, hana haɓakar baturi daga wurin sarrafa zafin jiki, yana hana haɓakar zafi a ciki. shirya.

A cikin gwajin acupuncture, fakitin baturi da aka tattara daga batura 18650, kuma lokacin da babu kayan PCC, yanayin zafi na baturi daga ƙarshe zai kai ga batura 20 a cikin fakitin baturi, kuma suyi amfani da kayan PCC. A cikin fakitin baturi, zafin baturi da ba a sarrafawa ba ya haifar da wasu fakitin baturi. Lithium-ion thermal thermal baturi wanda ba shi da iko shine mafi ƙarancin mu don ganin haɗarin aminci na rigakafi mai ƙarfi, haɓaka amincin batirin lithium-ion, hana zafin zafin jiki, da ƙirar sarrafa zafi daga ƙirar ƙirar baturi, ƙirar tsari da fakitin baturi.

Ƙarƙashin bututu na sama, haɗin gwiwar haɓaka ƙarfin ƙarfin baturi na lithium-ion, rage yiwuwar sarrafa asarar zafi. .
