Haɗari da fasahar aminci na batirin lithium ion (2)

3. Fasahar tsaro

Kodayake baturan lithium ion suna da hatsarori da yawa na ɓoye, ƙarƙashin ƙayyadaddun yanayin amfani da wasu ma'aunai, suna iya sarrafa yadda ya dace na halayen gefe da halayen tashin hankali a cikin ƙwayoyin baturi don tabbatar da amincin amfaninsu.Mai zuwa shine taƙaitaccen gabatarwa ga fasahohin aminci da yawa da ake amfani da su don batirin lithium ion.

(1) Zaɓi albarkatun ƙasa tare da mafi girman yanayin aminci

Za'a zaɓi kayan aiki masu kyau da mara kyau na polar, kayan diaphragm da electrolytes tare da mafi girman yanayin aminci.

a) Zaɓin abu mai kyau

Amintaccen kayan cathode ya dogara ne akan abubuwa uku masu zuwa:

1. Thermodynamic kwanciyar hankali na kayan;

2. Chemical kwanciyar hankali na kayan;

3. Kayan jiki na kayan aiki.

b) Zaɓin kayan aikin diaphragm

Babban aikin diaphragm shi ne raba ingantattun electrodes na baturi, da hana gajeriyar da'ira ta haifar da cudanya tsakanin masu amfani da na'urori masu inganci, da kuma ba da damar ion electrolyte su wuce, wato yana da insulation na lantarki da ion. rashin daidaituwa.Ya kamata a lura da waɗannan abubuwan yayin zabar diaphragm don baturan lithium ion:

1. Yana da rufin lantarki don tabbatar da keɓancewar injiniyoyi masu inganci da mara kyau;

2. Yana da wani buɗaɗɗen buɗewa da porosity don tabbatar da ƙarancin juriya da haɓakar ionic mai girma;

3. Kayan diaphragm zai sami isasshen kwanciyar hankali na sinadarai kuma dole ne ya kasance mai juriya ga lalatawar electrolyte;

4. Diaphragm zai sami aikin kariya ta atomatik ta atomatik;

5. Thermal shrinkage da nakasawa na diaphragm za su kasance a matsayin ƙananan kamar yadda zai yiwu;

6. Diaphragm zai kasance yana da wani kauri;

7. Diaphragm zai kasance yana da ƙarfin jiki mai ƙarfi da isasshen juriyar huda.

c) Zaɓin electrolyte

Electrolyte wani muhimmin bangare ne na batirin lithium ion baturi, wanda ke taka rawa wajen watsawa da gudanar da halin yanzu tsakanin ingantattun na'urorin lantarki na baturi.Electrolyte da aka yi amfani da shi a cikin batirin lithium ion shine maganin electrolyte da aka samar ta hanyar narkar da gishirin lithium masu dacewa a cikin gauraye masu kaushi.Gabaɗaya za ta cika buƙatu masu zuwa:

1. Kyakkyawan kwanciyar hankali na sinadarai, babu wani maganin sinadari tare da kayan aiki na lantarki, ruwa mai tarawa da diaphragm;

2. Kyakkyawan kwanciyar hankali na electrochemical, tare da taga mai fadi na lantarki;

3. Babban haɓakar ion lithium da ƙarancin wutar lantarki;

4. Faɗin zafin jiki na ruwa;

5. Yana da aminci, ba mai guba ba kuma yana da alaƙa da muhalli.

(2) Ƙarfafa ƙirar aminci gaba ɗaya na tantanin halitta

Kwamfutar baturi ita ce hanyar haɗin da ke haɗa nau'o'in kayan baturi, da kuma haɗakar da sandar igiya mai kyau, igiya mara kyau, diaphragm, lug da kuma shirya fim.Ƙirar tsarin tantanin halitta ba kawai yana rinjayar aikin kayan aiki daban-daban ba, har ma yana da tasiri mai mahimmanci akan aikin aikin lantarki na gaba ɗaya da aminci na baturi.Zaɓin kayan da aka tsara na ainihin tsarin shine kawai nau'in dangantaka tsakanin gida da duka.A cikin zane na ainihin, ya kamata a tsara yanayin tsarin da ya dace bisa ga halayen kayan aiki.

Bugu da kari, ana iya la'akari da wasu ƙarin na'urorin kariya don tsarin baturin lithium.Hanyoyin kariya gama gari sune kamar haka:

a) An karvi kashi na sauyawa.Lokacin da zafin jiki na cikin baturi ya tashi, ƙimar juriyarsa za ta tashi daidai da haka.Lokacin da zafin jiki ya yi yawa, za a dakatar da wutar lantarki ta atomatik;

b) Saita bawul ɗin aminci (wato, iskar iska a saman baturin).Lokacin da matsa lamba na ciki na baturin ya tashi zuwa wani ƙima, bawul ɗin aminci zai buɗe ta atomatik don tabbatar da amincin baturin.

Ga wasu misalan ƙirar aminci na tsarin ainihin wutar lantarki:

1. M da korau iyakacin duniya iya aiki rabo da zane size yanki

Zaɓi rabon ƙarfin da ya dace na na'urorin lantarki masu inganci da mara kyau bisa ga halaye na kayan lantarki masu inganci da mara kyau.Matsakaicin ƙarfin ƙarfin lantarki mai inganci da mara kyau na tantanin halitta muhimmiyar hanyar haɗi ce mai alaƙa da amincin batirin lithium ion.Idan ingantaccen ƙarfin lantarki ya yi girma da yawa, ƙarfe lithium zai ajiye akan saman na'urar da ba ta dace ba, yayin da ƙarfin wutar lantarki mara kyau ya yi girma, ƙarfin baturin zai yi ɓacewa sosai.Gabaɗaya, N/P=1.05-1.15, kuma za a yi zaɓin da ya dace bisa ga ainihin ƙarfin baturi da buƙatun aminci.Za a tsara manya da ƙananan ƙananan don haka matsayi na madaidaicin manna (abu mai aiki) ya rufe (wuce) matsayi na manna mai kyau.Gabaɗaya, nisa zai zama 1 ~ 5 mm girma kuma tsayin zai zama 5 ~ 10 mm girma.

2. Allowance don faɗin diaphragm

Gabaɗaya ƙa'idar ƙirar faɗin diaphragm ita ce hana gajeriyar da'ira ta ciki wanda ke haifar da hulɗa kai tsaye tsakanin ingantattun na'urorin lantarki da mara kyau.Kamar yadda zafin zafi na diaphragm yana haifar da nakasar diaphragm a cikin tsayi da nisa shugabanci yayin cajin baturi da fitarwa da kuma ƙarƙashin yanayin zafi da sauran wurare, polarization na yanki na nade na diaphragm yana ƙaruwa saboda karuwar nisa tsakanin tabbatacce. da na'urori marasa kyau;Yiwuwar ƙaramin gajeren kewayawa a cikin yanki mai shimfiɗa na diaphragm yana ƙaruwa saboda bakin ciki na diaphragm;Raunin a gefen diaphragm na iya haifar da tuntuɓar kai tsaye tsakanin ingantattun na'urorin lantarki da mara kyau da gajeriyar da'ira na ciki, wanda zai iya haifar da haɗari saboda guduwar baturi.Don haka, lokacin zayyana baturin, dole ne a la'akari da halayensa na raguwa a cikin amfani da yanki da faɗin diaphragm.Fim ɗin keɓewa ya kamata ya fi girma fiye da anode da cathode.Baya ga kuskuren tsari, fim ɗin keɓewa dole ne ya zama aƙalla 0.1mm tsawon fiye da gefen waje na yanki na lantarki.

3.Insulation magani

gajeriyar kewayawa na ciki muhimmin abu ne a cikin yuwuwar haɗarin aminci na baturin lithium-ion.Akwai yuwuwar ɓangarorin haɗari masu yawa waɗanda ke haifar da gajeriyar da'ira ta ciki a cikin tsarin ƙirar tantanin halitta.Don haka, ya kamata a saita matakan da suka dace ko rufewa a waɗannan mahimman wurare don hana gajeriyar da'ira na ciki a cikin baturi a ƙarƙashin yanayi mara kyau, kamar kiyaye tazarar zama dole tsakanin kunnuwan lantarki masu inganci da mara kyau;Za a liƙa tef ɗin da ba a liƙa ba a cikin tsakiyar ƙarshen ɗaya, kuma duk sassan da aka fallasa za a rufe su;Za a liƙa tef ɗin da ke rufewa tsakanin ingantaccen foil na aluminum da mummunan abu mai aiki;Za a rufe sashin walda na lugga gaba ɗaya tare da tef ɗin rufewa;Ana amfani da tef ɗin da aka rufe a saman tsakiyar wutar lantarki.

4.Setting aminci bawul (matsi taimako na'urar)

Batirin lithium ion suna da haɗari, yawanci saboda zafin jiki na ciki ya yi yawa ko kuma matsa lamba ya yi yawa don haifar da fashewa da wuta;Na'urar taimakon matsi mai ma'ana na iya saurin sakin matsa lamba da zafi a cikin baturin idan akwai haɗari, kuma yana rage haɗarin fashewar.Na'urar taimako mai ma'ana mai ma'ana ba kawai zata hadu da matsa lamba na ciki na baturin yayin aiki na yau da kullun ba, amma kuma buɗe ta atomatik don sakin matsa lamba lokacin da matsa lamba na ciki ya kai iyakar haɗari.Matsayin wuri na na'urar taimakon matsa lamba dole ne a tsara la'akari da halaye na lalacewa na harsashi batir saboda karuwar matsa lamba na ciki;Za'a iya gane ƙirar bawul ɗin aminci ta flakes, gefuna, seams da nicks.

(3) Inganta matakin tsari

Ya kamata a yi ƙoƙari don daidaitawa da daidaita tsarin samar da tantanin halitta.A cikin matakai na hadawa, shafi, yin burodi, compaction, slitting da winding, tsara ma'auni (kamar diaphragm nisa, ƙarar allurar lantarki, da dai sauransu), inganta tsarin tsari (kamar ƙananan hanyar allura, hanyar tattarawa ta centrifugal, da dai sauransu). , Yi aiki mai kyau a cikin sarrafa tsari, tabbatar da ingancin tsari, da kunkuntar bambance-bambance tsakanin samfurori;Saita matakan aiki na musamman a cikin mahimman matakai waɗanda ke shafar aminci (kamar ɓarna na yanki na lantarki, share foda, hanyoyin walda daban-daban don kayan daban-daban, da sauransu), aiwatar da daidaitaccen ingancin kulawa, kawar da ɓarna, da kawar da samfuran da ba su da lahani (kamar nakasar yanki na lantarki, huda diaphragm, faɗuwar abu mai aiki, yayyan lantarki, da sauransu);Tsabtace wurin samar da tsabta da tsabta, aiwatar da gudanarwa na 5S da kula da ingancin 6-sigma, hana ƙazanta da danshi daga haɗuwa a cikin samarwa, da kuma rage tasirin haɗari a cikin samarwa akan aminci.
