Babban tasirin baturi na lithium-ion, babban zafin jiki shine sanadin bututun batirin lithium-ion? Batirin lithium-ion yana da fa&39;idodin ƙarfin ƙarfin aiki mai ƙarfi, ƙarancin horo, babu tasirin ƙwaƙwalwar ajiya, babu gurɓatacce, yana da kyakkyawan fata game da batirin lithium baƙin ƙarfe phosphate ion a cikin sabon masana&39;antar makamashi, ana amfani da shi sosai a fagen batir lithium mai ƙarfi da ajiyar makamashi. Koyaya, saurin haɓakawa da aikace-aikacen suna da faɗi, amma zurfin bai gamsar da su ba, abubuwan da ke hana haɓaka haɓakarsu da sauri Baya ga farashin daidaiton tsari ta hanyar kayan batir, yanayin zafinsa shima muhimmin abu ne. Batir Lithium-ion babban tasirin zafin jiki A cikin duk abubuwan muhalli, zafin jiki yana rinjayar caji da fitarwar aikin baturi, amsawar electrochemical akan mahaɗin lantarki / electrolyte yana da alaƙa da yanayin yanayi, da haɓakar zafin jiki, ƙarfin fitarwar baturi na lithium ion zai tashi.

Hakanan zafin jiki yana rinjayar saurin watsawar ruwan electrolytic, kuma ana haɓaka haɓakar zafin jiki, ana saukar da yanayin canja wuri, watsawa yana jinkirin, kuma cajin baturi da aikin fitarwa shima zai shafi. Koyaya, zafin jiki ya yi girma sama da 45 ¡ã C don lalata ma&39;aunin sinadarai a cikin baturi, yana haifar da halayen gefe. Tasirin zafin jiki akan aikin fitarwa kai tsaye yana amsa ƙarfin fitarwa da ƙarfin fitarwa.

An saukar da zafin jiki, juriya na ciki yana ƙaruwa, ƙimar amsawar electrochemical yana jinkirin, ƙarancin juriya na ciki yana ƙaruwa, ƙarfin fitarwar baturi da dandamalin fitarwa, yana shafar fitowar ƙarfin baturi da kuzari. Ƙarfin ƙarfin baturi na lithium-ion yana da tasirin polarization baturi, wato, saurin watsawar lithium ion ba ya cikin saurin canja wurin electrons, ta yadda ions lithium da baturi ya kwana ya yi ƙasa da ƙasa. Wannan tsari na polarization yana ƙara tsananta a wani babban zafin jiki na 60 ¡ã C, wanda shine tushen dalilin rage ƙarfin baturi na lithium ion.

Tsarin gazawar zafin jiki na batirin lithium-ion ya fi rikitarwa a cikin magabata, kuma yana da wahala a bambance tsakanin asarar lithium mai aiki da asarar kayan aiki a ainihin bincike. Akwai lokacin lithium baƙin ƙarfe phosphate a cikinsa abin lithium phosphate shine lithium phosphate ya keɓanta daga tashar wutar lantarki da aka kafa ta hanyar damuwa na ciki, ta yadda asarar tunawa da lithium ba za a iya juyawa ba. Babban zafin jiki shine sanadin ganguna na baturin lithium-ion? 1 Yana bayyana a matsayin harsashin salula, don haka baturi buns ne kuma gargadin farko cewa baturin ya lalace ko yana iya samun matsalar tsaro.

2, yawan zafin jiki na baturi ya shafa, galibi ana adana kwayoyin halitta na dogon lokaci, kuma yanayin zafi zai kara saurin wasu sinadarai a cikin tantanin batir don samar da iskar gas, musamman idan baturin ya cika ko kadan ya wuce kima. Tasirin ajiyar zafin jiki mai girma a cikin wannan ya fi bayyane, don haka ya kamata a hana shi adanawa a cikin yanayin zafi. 3.

A yayin wannan tsari, ion lithium na electrode mara kyau yana karuwa, kuma yawan tarawa yana ba da damar atom ɗin lithium ya zama crystallized, ta yadda baturin ya yi kumbura. 4, fim din SEI zai hana kayan lantarki mara kyau, don haka tsarin kayan ba shi da sauƙi a rushewa, kuma za&39;a iya ƙara rayuwar sake zagayowar kayan lantarki. Fim ɗin SEI ba na dindindin ba ne, za a sami ɗan canji kaɗan yayin aiwatar da caji da fitarwa, yana da mahimmanci cewa wasu kwayoyin halitta zasu iya canzawa.

Bayan da baturi ya wuce kima, fim din SEI yana faruwa a sake dawowa don karya zobe, kuma lalata SEI na kayan lantarki mara kyau ya sa kayan lantarki mara kyau ya rushe, ta haka ya zama babban abin mamaki. Hanyoyin sunadarai da electrochemical na baturan lithium-ion a yanayin zafi suna da matukar rikitarwa, nazarin tsarin amsawa tsakanin abun da ke ciki na baturi, da kuma inganta abubuwan da suka faru na nau&39;i na nau&39;i na exothermic daban-daban, inganta aikin aminci a ƙarƙashin cin zarafin baturi yana da mahimmanci. Batura lithium-ion suna shafar yanayin zafi, dangane da yanayin aikace-aikacen a cikin filin da zazzabi na baturin lithium mai ƙarfi, don haɓaka ƙarfin baturi, tsawaita rayuwar tsarin batir.
