Bayanan aikin baturin lithium ion

  Lithium-ion battery is an indispensable energy storage product that drives human modern life, Lithium ion batteries are indispensable for daily communication, energy storage, household appliances, electric vehicles, electric ships, etc. And in special applications such as military, deep sea, and mining, lithium-ion batteries are characterized by their high energy density, long service life, and superior safety performance, Widely replaced the traditional lead-acid batteries, nickel-metal hydride batteries and other previous generation products.

Lithium-ion baturi ne a fasaha-m masana'antu, The ci gaban wannan masana'antu kuma iya rayayye fitar da ci gaban da kasar kayan aiki masana'antu da kuma kayan masana'antu. Advanced membrane fasahar, atomatik taron line fasahar, low raɓa batu da high tsabta iska yanayi fasahar da kuma m kayan aiki amfani a cikin core aiwatar da lithium ion baturi masana'antu, Yana yana da m shiriya da nuni rawa ga ci gaban sauran masana'antu fasahar da kayan aiki. Abubuwan da ake amfani da su a cikin batura lithium-ion za a iya haɗa su tare da taman jan karfe na gida, cobalt tama da graphite tama don aiki mai zurfi zuwa cikin tagulla mai bakin ciki don batir lithium-ion, lithium cobaltate (lithium nickel cobalt manganate) kayan cathode, da manyan- makamashi graphite anode kayan.

Duk da cewa batirin lithium-ion a halin yanzu shine mafi shaharar nau'in baturi, tare da bunkasar fasaha, akwai nau'ikan batirin lithium-ion iri-iri, kowannensu yana da nasa fa'ida da rashin amfani. Koyaya, gabaɗaya, batirin lithium-ion suna da fa'idodi da rashin amfani gama gari:

1. Amfanin batir lithium-ion.

(1) Babban ƙarfin lantarki: ƙarfin aiki na baturi ɗaya zai iya kaiwa sama da 3.7-3.8V (ana iya cajin mafi girman ƙarfin tantanin halitta har zuwa 4.2V), wanda shine sau uku na batirin Ni Cd da Ni-H.

(2) Babban ƙayyadaddun makamashi: A halin yanzu, ainihin takamaiman ƙarfin da za a iya samu shine kusan 555Wh / kg, wanda ke nufin cewa kayan zai iya isa takamaiman ƙarfin fiye da 150mAh / g (3-4 sau Ni Cd, 2-3). times Ni MH), wanda ke kusa da kusan kashi 88% na ƙimar ka'idar sa.

(3) Rayuwa mai tsayi: gabaɗaya na iya kaiwa fiye da sau 500, ko ma fiye da sau 1000, kuma sinadarin baƙin ƙarfe na lithium zai iya kaiwa fiye da sau 2000. Tsawon rayuwar batura a cikin ƙananan na'urorin fitarwa na yanzu zai ninka gasa.

(4) Kyakkyawan aikin aminci: rashin gurbatawa, babu tasirin ƙwaƙwalwar ajiya. A matsayin magabata na Li-ion, batirin lithium-ion sun rage wuraren da ake amfani da su saboda samuwar dendrites da gajerun da'ira ta hanyar lithium na karfe. Li-ion ba ya ƙunshi abubuwan da ke gurbata muhalli kamar cadmium, gubar, da mercury. Babban koma baya na wasu batir Ni Cd a wasu matakai (kamar sintering) shine "tasirin ƙwaƙwalwar ajiya", wanda ke da matuƙar ƙuntata amfani da batura. Koyaya, Li-ion ba shi da wannan matsalar kwata-kwata.

(5) Rashin fitar da kai: Yawan fitar da kai na Li ion, wanda ake caje shi a cikin daki kuma ana adana shi tsawon wata ɗaya, ya kai kusan kashi 2%, ƙasa da 25-30% na Ni Cd da 30-35% na Ni da MH.

(6) Yin caji da sauri: Ƙarfin zai iya kaiwa sama da 80% na ƙarfin ƙima bayan minti 30 na caji, kuma yanzu baturan ƙarfe na phosphate na iya kaiwa kashi 90% na ƙarfin ƙima bayan minti 10 na caji.

(7) Babban zafin jiki na aiki: Yanayin aiki shine -25 ~ 55 ° C. Tare da haɓakawa na lantarki da ingantaccen lantarki, ana sa ran fadada zuwa -40 ~ 70 ° C.

2. Lalacewar batirin lithium-ion

(1) Tsufa: Ba kamar sauran batura masu caji ba, ƙarfin batirin lithium-ion zai ragu sannu a hankali, ba tare da adadin amfani ba, amma yana da alaƙa da zafin jiki. Hanyar da za ta yiwu ita ce juriya na ciki a hankali yana ƙaruwa, don haka yana iya nunawa a cikin samfurori na lantarki tare da manyan igiyoyin aiki. Maye gurbin graphite da lithium titanate da alama yana ƙara tsawon rayuwa.

(2) Rashin iya jurewa caji mai yawa: Yayin da ake yin caja, ions lithium da aka saka fiye da kima za su daidaita su har abada kuma ba za a iya sakin su ba, wanda zai iya haifar da ƙarancin batir da samar da iskar gas yana haifar da kumfa.

(3) Rashin jurewa akan fitar ruwa: Yayin da ake fitar da ruwa, ana cire ion lithium da ya wuce kima daga wutar lantarki, wanda zai iya haifar da rugujewar latti, ya rage tsawon rayuwa, da haifar da samar da iskar gas, yana haifar da kumfa.

(4) Ana buƙatar hanyoyin kariya da yawa: Saboda gaskiyar cewa yin amfani da ba daidai ba na iya rage tsawon rayuwa har ma da haifar da fashewa, an ƙara hanyoyin kariya da yawa zuwa ƙirar batir lithium-ion.

Da'irar kariyar: hana yin caji fiye da kima, fiye da fitar da kaya, da yawa, da zafi fiye da kima.

Ƙarfafa tashar jiragen ruwa: don hana matsa lamba mai yawa a cikin baturi.

Halayen diaphragm: Yana da babban juriya na huda don hana gajerun da'irori na ciki; Lokacin da zafin ciki na baturi ya yi girma, zai iya narke har yanzu, hana lithium ions wucewa, toshe halayen baturi, da ƙara juriya na ciki (har zuwa 2kQ).

A taƙaice, ci gaban masana'antar batir lithium-ion wata masana'anta ce mai ƙarfi wacce ke haɓaka ƙasashe masu tasowa zuwa ƙasashe masu tasowa.
