Sooyaalka mashruuca baytariyada 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.

Batariyada lithium-ion waa warshad-teknooloji-degdeg ah, horumarinta warshadahan ayaa sidoo kale si firfircoon u kicin kara horumarinta qalabka dalka iyo warshadaha qalabka. Tiknoolajiyada xuubka sare, tikniyoolajiyadda khadka tooska ah ee tooska ah, barta sayaxa hooseeya iyo tignoolajiyada hawada nadiifka ah ee hawada sare iyo qalabka u dhigma ee loo isticmaalo habka ugu muhiimsan ee wax soo saarka batteriga lithium-ion, waxay leedahay hanuunin togan iyo doorka muujinta horumarinta tignoolajiyada kale ee warshadaha iyo qalabka. Qalabka loo isticmaalo baytariyada lithium-ion waxaa lagu dhex dari karaa macdanta naxaasta ah ee maxaliga ah, cobalt ore iyo graphite ore si qoto dheer loogu farsameeyo foil naxaas ah oo aad u khafiif ah oo loogu talagalay baytariyada lithium-ion, lithium cobaltate (lithium nickel cobalt manganate) qalabka cathode, iyo sare- qalabka graphite anode tamarta.

Inkasta oo baytariyada lithium-ion ay wakhtigan yihiin nooca ugu caansan ee baytariyada, marka la horumariyo tignoolajiyada, waxa jira noocyo badan oo baytariyada lithium-ion ah oo mid kastaa leeyahay faa'iidooyin iyo faa'iido darrooyin u gaar ah. Si kastaba ha ahaatee, guud ahaan, baytariyada lithium-ion waxay leeyihiin faa'iidooyinka iyo khasaaraha guud ee soo socda:

1. Faa'iidooyinka baytariyada lithium-ion.

(1) Voltage sare: Korantada shaqada ee hal batari waxa ay gaadhi kartaa ilaa 3.7-3.8V (kuwa ugu sareeya ee tamarta waxa lagu dalaci karaa ilaa 4.2V), taas oo saddex jeer ka badan baytariyada Ni Cd iyo Ni-H.

(2) Tamar gaar ah oo sare: Waqtigan xaadirka ah, tamarta gaarka ah ee dhabta ah ee la gaari karo waa qiyaastii 555Wh / kg, taas oo macnaheedu yahay in maaddadu ay gaari karto awood gaar ah oo ka badan 150mAh / g (3-4 jeer Ni Cd, 2-3). times Ni MH), kaas oo ku dhow ilaa 88% qiimaheeda aragtiyeed.

(3) Nolosha wareegga dheer: guud ahaan waxay gaari kartaa in ka badan 500 jeer, ama xitaa in ka badan 1000 jeer, iyo phosphate iron lithium waxay gaari kartaa in ka badan 2000 jeer. Cimriga baytariyada ku jira qalabka dareeraha hooseeya ee hadda jira waxay labanlaabmi doonaan tartankooda.

(4) Waxqabadka wanaagsan ee badbaadada: wasakh la'aan, wax saameyn ah oo xusuusta ah ma leh. Sida kii ka horreeyay ee Li-ion, baytariyada lithium-ion waxay hoos u dhigeen aagagga codsiga sababtoo ah samaynta dendrites iyo wareegyada gaaban ee ay keento lithium macdan ah. Li-ion kuma jiraan waxyaabo wasakheeya deegaanka sida cadmium, rasaasta, iyo meerkuriga. Dib u dhac weyn oo ku yimid qaar ka mid ah baytariyada Ni Cd ee hababka qaarkood (sida sintering) waa "saamaynta xusuusta", taas oo si dhab ah u xaddidaysa isticmaalka baytariyada. Si kastaba ha ahaatee, Li-ion ma laha dhibaatadan gabi ahaanba.

(5) Dheecaan hoose: Heerka iskii u soo daacida ee Li ion, kaas oo si buuxda loogu dalaco heerkulka qolka laguna kaydiyo hal bil, waa ilaa 2%, aad uga hooseeya 25-30% Ni Cd iyo 30-35% Ni iyo MH.

(6) Dallacaadda degdegga ah iyo dallacaadda: Awooddu waxay gaari kartaa in ka badan 80% awoodda magaca ka dib 30 daqiiqo oo dallad ah, iyo hadda baytariyada birta fosfat waxay gaari karaan 90% awoodda magaca ka dib 10 daqiiqo oo dallad ah.

(7) Heerkulka heerkulka sare ee shaqada: Heerkulka shaqadu waa -25 ~ 55 ° C. Iyadoo hagaajinta korantada iyo korantada togan, waxaa la filayaa in la ballaariyo ilaa -40 ~ 70 ° C.

2. Khasaaraha baytariyada lithium-ion

(1) Gabowga: Si ka duwan baytariyada kale ee dib loo dallaci karo, awoodda baytariyada lithium-ion ayaa si tartiib tartiib ah hoos u dhacaya, oo ka madax bannaan tirada isticmaalka, laakiin la xidhiidha heerkulka. Habka suurtogalka ah waa in iska caabbinta gudaha si tartiib tartiib ah u korodho, sidaas darteed waxay u badan tahay in ay ka muuqato alaabta elektaroonigga ah ee leh qulqulo shaqeynaya. Ku beddelashada garaafka lithium titanate waxay u muuqataa inay kordhinayso cimriga.

(2) Awood la'aanta in ay xamili kari la'dahay dallacaadda xad-dhaafka ah: Inta lagu jiro dallacaadda xad-dhaafka ah, ion lithium-ka xad-dhaafka ah ee ku-xidhan ayaa si joogto ah u hagaajin doona xargaha oo aan la sii dayn karin, taas oo keeni karta cimriga batteriga oo gaaban iyo soosaarka gaaska oo keenaya goobooyin gaas ah.

(3) Awood la'aanta u adkeysiga dheecaanka ka badan: Inta lagu jiro dheecaanka, ion lithium-ka xad-dhaafka ah ayaa laga saaraa electrode-ka, taas oo keeni karta burburka qulqulka, yaraynta cimriga, iyo sababa abuurista gaas, taasoo keenta goobooyin gaas ah.

(4) Habab dhowr ah oo ilaalin ah ayaa loo baahan yahay: Sababo la xiriira xaqiiqda ah in isticmaalka khaldan uu yarayn karo cimriga oo xitaa keeni kara qaraxyo, habab dhowr ah oo ilaalin ah ayaa lagu daray naqshadeynta baytariyada lithium-ion.

Wareegga ilaalinta: ka hortagga dallacaadda xad-dhaafka ah, daadinta xad-dhaafka ah, culeyska xad-dhaafka ah, iyo kulaylka xad-dhaafka ah.

Dekadda qiiqa: si looga hortago cadaadiska xad dhaafka ah ee gudaha batteriga.

Sifooyinka diaphragm: Waxay leedahay iska caabin dalool sare leh si looga hortago wareegyada gaaban ee gudaha; Marka heerkulka gudaha batteriga uu aad u sarreeyo, weli wuu dhalaali karaa, ka ilaalin karaa ion lithium-ka inay dhex maraan, xannibo falcelinta baytariyada, oo kordhiyaa caabbinta gudaha (ilaa 2kQ).

Isku soo wada duuboo, horumarinta warshadaha baytariyada lithium-ion waa warshado awood leh oo u gudbisa wadamada soo koraya wadamada horumaray.
