Mocheso o tsoileng taolong ke kotsi e mpe ka ho fetisisa ea polokeho ts&39;ebelisong ea libeteri tsa lithium-ion. Mocheso o sa laoleheng hangata o bakoa ke betri ea lithium ion eo ho eona diaphragm e senyehang, kapa diaphragm e robehile, kapa ka lebaka la potoloho e khutšoanyane e ka ntle ka ntle ho betri. E bakile mocheso o mongata, o bakang mocheso o mongata, o qala ntho e ntle le e mpe ea electrode e sebetsang le electrolyte, e bakang betri ea lithium-ion ho thibela le ho phatloha, ho sokela bophelo le polokeho ea thepa ea basebelisi ka ho teba.

Ka hona, betri ea lithium-ion ka kakaretso e tla hlokoa ha ho sibolloa ts&39;ireletso ea betri ea lithium ion, &39;me betri ea lithium ion e hlokahala ho feta tefiso e ngata, overprint, potoloho e khuts&39;oane le extrusion, acupuncture, empa ka ntlafatso e tsoelang pele ea matla a matla a lithium betri le matla a betri, betri e fetisitse acupuncture Teko e ile ea e-ba thata le ho feta, kahoo tlhahlobo ea acupun ha e sebelisoe tekong " Litlhoko tsa Likoloi tsa Motlakase] li phatlalalitsoe Lefapheng la Indasteri le Theknoloji ea Boitsebiso. Leha ho le joalo, mofuta o mocha ha o hloke letho ho etsa tlhahlobo ea acupuncture. Ka mor&39;a moo, ho ke ke ha khoneha ho e tsosolosa.

Haeba moetsi a fihlela bokhoni bo boholo, matla a matla a matla a lithium betri a boreleli ka tlhahlobo ea acupuncture, joale e tla ba ea bohlokoa tlhōlisanong. Melemo. Kajeno re tla bua ka mekhoa eo "brake" ho lahleheloa ke "mariki" ho libeteri tsa lithium-ion.

1. Electrolytic liquid flame retardant electrolyte flame retardant ke tsela e atlehang haholo ea ho fokotsa mocheso oa betri ho tsoa taolong, empa li-retardants tsena tsa lelakabe hangata li na le tšusumetso e matla ts&39;ebetsong ea electrochemical ea libeteri tsa lithium-ion, kahoo ho thata ho li sebelisa ha li sebelisoa. E le ho rarolla bothata bona, sehlopha sa Yuqiao sa Sheng Diego, California, Chaena [1] se boloka lelakabe la DBA (dibenzylamine) ka hare ho li-microcapsules tabeng ea sephutheloana sa capsule, ho hasana ka electrolyte, ho ke ke ha e-ba le ts&39;ebetso ea motlakase ea betri ea lithium-ion e susumetsoa, ​​empa ha betri e senngoa ke li-capsules, letlapa le tla lokolloa. "Chefo" e baka ho hloleha ha betri, ka hona ho thibela ho hlaha ha mocheso ho tsoa taolong.

Sehlopha sa 2018 Yuqiao [2] se boetse se sebelisa mokhoa o ka holimo, ethylene glycol le ethylenediamine li sebelisoa e le sehlaseli sa mollo, &39;me karolo e ka hare ea betri ea lithium ion e kenngoa ka har&39;a betri ea lithium-ion e theohile ka 70% tekong ea acupuncture. E fokolitse haholo kotsi ea ho tsoa taolong ea libeteri tsa lithium ion. Tsela e boletsoeng ka holimo ke ho itšeha, ke hore, hang ha ho sebelisoa lelakabe la lelakabe, betri eohle ea lithium-ion e tla tlosoa, &39;me sehlopha sa Atsuoyamada sa Univesithi ea Tokyo, Japane [3] se hlahisitse mofuta o bakoang ke lithium Flame retardant electrolyte ea ion battery properties, tharollo ea electrolytic e sebelisa likarolo tse phahameng tsa Nalin (SO2F) kapa Nalin (SO2F) kapa Nalin (SO2F) (LIFSA) e le letsoai la lithium, &39;me ho eketsoa lelakabe le tloaelehileng la mollo ho eona.

Ester TMP e ntlafalitse haholo botsitso ba mocheso oa betri ea lithium-ion, e leng matla le ho feta. Ho eketsoa ha lelakabe la lelakabe ha le ame ts&39;ebetso ea potoloho ea betri ea lithium ion, mme betri e amohela electrolyte e ka tsamaisoa ka mokhoa o tsitsitseng ho feta makhetlo a 1000 (C / 5) makhetlo a 1200 ho potoloha, sekhahla sa ho boloka matla 95%). Ka tlatsetso, betri ea lithium ion e na le thepa e thibelang lelakabe ho thibela e &39;ngoe ea litsela tsa mocheso ho tsoa taolong ea libeteri tsa lithium ion,&39; me batho ba bang ba na le tsela e &39;ngoe, ho leka ho thibela ho hlaha ha lipotoloho tse khutšoane ka libeteri tsa lithium ion tse bakoang ke motso ho tsoa sesosa, ka hona ho fihlela sepheo sa ho nka botlaaseng ba kettle.

Ka ho feletseng felisa ketsahalo ea mocheso tsoa taolong. Bakeng sa betri ea lithium e ntseng e sebelisoa, e ka tobana le tšusumetso e matla, Gabrielm oa American Oak Ridge National Laboratory. Veith e entse electrolyte [4] e nang le thepa e teteaneng ea ho kuta, e sebelisang litšobotsi tsa mokelikeli oo e seng oa Newtonian.

Boemong bo tloaelehileng, electrolyte e fana ka boemo ba mokelikeli, empa ha e kopana le ts&39;usumetso ea tšohanyetso Boemo bo tiileng bo tla etsoa ka mokhoa o sa tloaelehang, &39;me bo ka ba ba finyella phello ea bulletproof. Ho tloha sesosa sa sesosa, kotsi ea ho lahleheloa ke mocheso ka betri e thibeloa nakong ea ho senyeha ha betri ea lithium ea matla. 2.

Sebopeho sa betri se re nka ho bona mokhoa oa ho fana ka mocheso ho tsoa taolong, &39;me betri ea hona joale ea lithium-ion e ntse e nahana ka bothata ba mocheso o sa laoleheng moralong oa sebopeho, joalo ka sekoahelo se ka holimo sa 18650. Ka kakaretso ho na le valve e fokotsang khatello, &39;me hoa khoneha ho lokolla khatello ka hare ho betri nakong ea mocheso o sa laoleheng. The positive mocheso coefficient material PTC sekoahelong sa bobeli sa betri e ka holimo e eketseha haholo ha mocheso oa tahlehelo ea mocheso o eketseha.

Fokotsa hona joale ho fokotsa mocheso. Ho phaella moo, moralo oa potoloho e khutšoanyane pakeng tsa li-electrode tse ntle le tse mpe li nkoa ka moralo oa mohaho oa betri ea monomer, le lintlha tse kang ho se sebetse hantle, lintho tsa tšepe, joalo-joalo, tse bakang likotsi tsa tšireletso.

Ea bobeli, ha betri e etsoa, ​​​​ho sebelisoa diaphragm e sireletsehileng haholoanyane, mohlala, diaphragm e entsoeng ka likarolo tse tharo ea shuttle e itekanetseng ka mocheso o phahameng, empa lilemong tsa morao tjena, ka ntlafatso e tsoelang pele ea matla a betri, diaphragm e entsoeng ka likarolo tse tharo e &39;nile ea e-ba The ceramic coating diaphragm e ileng ea felisoa butle-butle, lesela la ceramic le ka sebelisoa. karohano ka mocheso o phahameng, ntlafatsa botsitso ba mocheso oa betri ea lithium ion, ho fokotsa kotsi ea ho tsoa taolong ea libeteri tsa lithium ion. 3. Moralo oa polokeho ea mocheso oa betri Matla a lithium betri a atisa ho sebelisoa, makholo kapa esita le likete tsa libeteri tse nang le tjantjello, joalo ka li-betri tsa Tesla&39;s Models tse tsoang ho feta 7,000.

Sebopeho sa 18650, haeba e &39;ngoe ea libeteri e etsahala, e ka&39; na ea ata ka har&39;a betri, e baka liphello tse tebileng. Ka mohlala, ka Pherekhong 2013, sefofane sa Japanese Airlines sa Boston, USA, sefofane sa baeti sa Boeing 787, se ipapisitse le liphuputso tsa US National Transport Safety Commission, se bakoa ke betri ea 75AH square lithium-ion ka har&39;a betri pakete. Ka mor&39;a tahlehelo ea taolo, mocheso o haufi oa betri o tsoile taolong.

Kamora ketsahalo eo, Boeing o ile a kopa mehato ea ho kenyelletsa sets&39;oants&39;o se chesang se tsoileng taolong ho lipakete tsohle tsa betri. E le ho thibela mocheso hore o se ke oa laoloa ka hare ho betri ea lithium ion, US AllCelltechnology e thehile lisebelisoa tsa ho itšehla thajana tsa lithium-ion battery thermal out-control tse thehiloeng ho lisebelisoa tsa phetoho ea mohato [5]. Lisebelisoa tsa PCC li tlatsitsoe pakeng tsa betri ea lithium ion ea monomer, haeba pakete ea lithium ion betri e sebetsa hantle, mocheso oa betri o ka fetisetsoa ka potlako ho pakete ea betri ka thepa ea PCC, &39;me ha ho lahleheloa ke mocheso oa betri ea lithium ion, thepa ea PCC E ka qhibiliha ka thepa ea parafine ho monya mocheso o mongata, ho thibela ho ata ha betri ka hare ho eona, ho thibela ho ata ha betri ho feta moo. phuthela.

Tekong ea acupuncture, pakete ea betri e kentsoeng ho tloha libeteri tsa 18650, &39;me ha ho se na lisebelisoa tsa PCC, mocheso oa betri o sa laoleheng o tla qetella o lebisitse ho li-betri tsa 20 ka har&39;a betri pakete,&39; me u sebelise lisebelisoa tsa PCC. Ka har&39;a pakete ea betri, mocheso oa betri o tsoileng taolong ha o kenye lipakete tse ling tsa betri. Lithium-ion battery thermal out-of control ke ho tsilatsila ha rona ka ho fetisisa ho bona kotsi ea tšireletso ea thibelo e matla, ho ntlafatsa polokeho ea libeteri tsa lithium-ion, ho thibela mocheso o sa laoleheng, le moralo oa tsamaiso ea mocheso ho tloha ho moralo oa mokhoa oa betri, moralo oa moralo le betri pakete.

Tlas&39;a tube e ka holimo, ho ntlafatsa ts&39;ebetso ea thermostability ea lithium-ion betri, ho fokotsa monyetla oa ho laola mocheso. .
