Soo koobid horumarkii ugu dambeeyay iyo rajada horumarka ee cilmi baarista batteriga lithium-ion ee amniga sare. Muhiim ka ah xasiloonida heerkulka sare ee electrolytes iyo electrodes, sababaha xasiloonida kulaylka baytariyada lithium ion iyo habab ay caddeeyeen in nidaamka batari lithium-ion ganacsi ee jira waa ku filnayn heerkulka sare, soo jeedinaysaa in la horumariyo heerkulka sare ee electrolytes, wax ka beddelka togan iyo taban iyo maamulka batteriga dibadda, iwm. si loo naqshadeeyo baytariyada lithium-ion oo ammaankoodu sarreeyo.

Muuqaalka horumarinta rajada farsamada ee horumarinta baytariyada lithium-ion ee badbaadada. 0 Horudhac baytariyada lithium ion waxay noqdaan wakiil caadi ah nooc cusub oo tamar ah iyadoo ay ugu wacan tahay qiimaheeda yar, wax qabadkeeda sare, awooda sare, iyo deegaanka cagaaran, oo si weyn loogu isticmaalo alaabada dhijitaalka ah ee 3C, awooda mobilada iyo qalabka korantada. Sanadihii la soo dhaafay, iyadoo ay ugu wacan tahay xoojinta wasakheynta deegaanka iyo hagidda siyaasadda qaranka, suuqa gawaarida korantada ee gawaarida korantada ayaa kor u qaaday baahida baytariyada lithium-ion, habka horumarinta nidaamyada batteriga lithium-ion ee awoodda sare leh, arrimaha badbaadada batteriga ayaa soo jiitay fiiro gaar ah , Dhibaatooyinka jira waxay si degdeg ah ugu baahan yihiin in la sii xalliyo.

Isbedelka heerkulka nidaamka batteriga waxaa lagu go&39;aamiyaa soo bixitaanka kulaylka waxaana loo qaybiyaa laba arrimood. Dhacdooyinka kulaylka baytariyada lithium ion waa muhiim waxaa sababa falcelinta ka dhaxaysa kala-goynta kulaylka iyo walxaha batteriga. Iska yaree kulaylka nidaamka batteriga oo wanaaji nidaamka waxqabadka heerkulka-sare, nidaamka batteriga waa badbaado.

Qalabka yar yar ee la qaadi karo sida taleefannada gacanta, awoodda batteriga laptop-ka guud ahaan waa wax ka yar 2AH, awoodda batteriga nooca lithium-ion ee loo isticmaalo gawaarida korantada guud ahaan waa ka weyn tahay 10ah, heerkulka maxalliga ah wuxuu badanaa ka sarreeyaa 55 ° C inta lagu jiro hawlgalka caadiga ah, heerkulka gudaha wuxuu gaari doonaa 300 ° C xakamaynta iyo gubashada baytariga ama qaraxa [3]. Marka laga soo tago qodobbada jawaab-celinta kiimikada ee u gaarka ah, dadka qaarkiis waxay leeyihiin wareeg gaaban oo ay keento kuleyl, dhaafin, iyo saameyn farsamo, qaar ka mid ah arrimo macmal ah ayaa sidoo kale u horseedi kara inay dhacdo baytari lithium-ion si ay u keento shilalka badbaadada. Sidaa darteed, waa muhiim in la barto oo la wanaajiyo waxqabadka heerkulka sare ee baytariyada lithium-ion.

1 kulaylka-ka-baxsan-koontaroolka ayaa sabab u ah falanqaynta kulaylka oo ka baxsan xakamaynta baytariga lithium-ion waa muhiim sababtoo ah heerkulka gudaha ee batteriga ayaa kor u kacaya. Waqtigan xaadirka ah, nidaamka elektrolytka ee inta badan loo isticmaalo baytariyada lithium-ion ee ganacsiga waa xal karboonayt ah oo isku dhafan oo ah LiPF6. Walxaha noocan oo kale ah wuxuu leeyahay isbeddel sare, barta iftiimaya hooseeya, aad u fudud in la gubo.

Marka wareegga gaaban ee gudaha ee uu keeno isku dhac ama qallafsanaan, lacag badan oo xajmi ah iyo soo dajin iyo kor u kac, waxaa jiri doona kuleyl badan, taasoo keentay in kor loo qaado heerkulka batteriga. Marka la gaaro heerkul gaar ah, falcelinno isdaba joog ah ayaa sababi doona in dheellitirka kulaylka batteriga uu burburo. Marka kulaylka ay sii daayaan fal-celinta kiimikaad aan laga bixi karin wakhtiga, waxay ka sii dari doontaa horumarka falcelinta, waxayna kicin doontaa falcelino is-kuleyl ah oo isdaba-joog ah.

Heerkulka baytarigu si xoog leh ayuu kor ugu kacayaa, taas oo ah, "kuleylka oo aan xakameynin", ugu dambeyntiina wuxuu horseedaa gubashada batteriga, xitaa qarax ayaa si dhab ah u dhaca. Guud ahaan, sababta kuleylku ka baxsan yahay xakamaynta baytariyada lithium-ion waxay muhiim u tahay xasilloonida kulaylka electrolyte, iyo sidoo kale xasilloonida kulaylka ee electrolyte iyo wada noolaanshaha korantada togan iyo taban. Waqtigan xaadirka ah, marka laga eego dhinaca weyn, badbaadada baytariyada lithium-ion waxay muhiim u tahay maareynta dibadda iyo naqshadeynta gudaha si loo xakameeyo heerkulka gudaha, korantada, iyo cadaadiska hawada si loo gaaro ujeedooyinka badbaadada.

2 Xalli kulaylka ka baxsan istaraatiijiyada 2. Maaraynta dibadda 1) PTC (positive heat coefficient) qayb: Ku rakib qaybta PTC ee baytari lithium ion ah, taas oo tixgalinaysa cadaadiska iyo heerkulka gudaha batteriga, iyo marka batteriga lagu kululeeyo xad-dhaaf ah, batarigu waa 10 Caabbigu wuxuu kordhiyaa si uu u xaddido hadda, iyo danab u dhexeeya tiirarka togan iyo kuwa taban waxaa la dhimay danab badbaado leh si loo xaqiijiyo shaqada ilaalinta tooska ah ee batteriga. 2) Waalka aan qarxin: Marka uu baytarigu aad u weyn yahay cillad aan caadi ahayn awgeed, waalka aan qarxin wuu qallafsan yahay, kaas oo la gelin doona gudaha batteriga si loogu xiro, jooji dallacaadda.

2.2.4 Polymer Electrolyte Batariyaal badan oo badeecooyin ah oo lithium ion ah ayaa isticmaala dareerayaasha kaarboonaytiga ah ee guban kara iyo kuwa kacsan, haddii ay u badan tahay in dareeruhu uu dab keeno.

Tani waxay si gaar ah u tahay baytariyada lithium-ion ee awoodda leh ee awoodda sare leh, cufnaanta tamarta sare. Halkii laga isticmaali lahaa electrolytes polymer-ka aan damiir lahayn halkii laga isticmaali lahaa electrolytes dareere organic ah oo guban kara, waxay si weyn u wanaajin kartaa badbaadada baytariyada lithium-ion. Cilmi-baarista polymer electrolyte, gaar ahaan nooca jel-polymer electrolyte ayaa sameeyay horumar weyn.

Waqtigan xaadirka ah, waxaa si guul leh loogu isticmaalay baytariyada lithium-ion ee ganacsiga. Marka loo eego kala-soocidda jirka polymer-ka, jel-ka-koobka-ka-soo-baxa wuxuu muhiim u yahay saddexda qaybood ee soo socda: PAN-based polymer electrolyte, PMMA polymer electrolyte, PVDF-based polymer electrolyte. Si kastaba ha ahaatee, nooca jel-polymer electrolyte dhab ahaantii waa natiijo ka dhalatay tanaasulka polymer electrolyte qalalan iyo dareeraha dareeraha ah ee dareeraha ah, iyo baytariyada nooca jel-ka ah ayaa weli haysta shaqo badan oo ay qabtaan.

2.3 Walaxda wanaagsan ayaa go&39;aamin karta in qalabka korantada togan uu yahay mid aan xasilloonayn marka korantada gobolka ee ku dallacadu ay ka sarreyso 4V, waana sahlan tahay in la dhaliyo kulaylka lagu kala diro heerkulka sare si ay u jajabiso oksijiinta, oksijiinta iyo dareerayaasha organic waxay sii wadaan inay ka falceliyaan xaddi badan oo kulaylka iyo gaasaska kale, waxay yareeyaan badbaadada batteriga [2, 17-19]. Sidaa darteed, falcelinta korantada togan iyo korantada ayaa loo arkaa inay tahay sabab muhiim ah oo kuleyl ah.

Marka laga hadlayo walxaha caadiga ah, wanaaji habka caadiga ah ee ammaankeeda waa wax ka beddelka dahaarka. Waayo, daahan dusha sare ee alaabta electrode togan la MgO, A12O3, SiO2, TiO2, ZnO, SnO2, ZrO2, iwm, hoos u dhigi kartaa falcelinta ee Die +-dambe positive iyo electrolyte halka hoos u chromatography ee electrode togan, la joojiyo isbedelka wajiga walax electrode togan.

Dabeecadda DR iyo TGA-u-eg macnaheedu waxa weeye waxay tusinaysaa inaysan ilaalin karin xasilloonida kulaylka ee 500 ° C, laakiin sidoo kale ay leeyihiin galitaanka korantada ee ka wanaagsan marka loo eego diaphragm CELGARD. WANG et al waxay diyaariyeen AL2O3-PVDF nanoscopic microporous xuubka, kaas oo soo bandhigaya sifooyinka korantada ee wanaagsan iyo xasiloonida kulaylka, qancinta isticmaalka kala-saarayaasha baytariga lithium-ion.

3 Soo koobid oo filo baytariyada lithium-ion ee baabuurta korantada iyo kaydinta tamarta, taas oo aad uga weyn qalabka yar yar ee elektiroonigga ah, iyo jawiga isticmaalka ayaa aad u dhib badan. Isku soo wada duuboo, waxaan arki karnaa in amnigeedu uu ka fog yahay in la xaliyo, oo noqday caqiidada farsamo ee hadda taagan. Shaqada xigta waa inay si qoto dheer u ahaataa saamaynta kulaylka ee batteriga laga yaabo inuu keeno ka dib qalliin aan caadi ahayn, oo hel hab wax ku ool ah oo lagu wanaajiyo waxqabadka badbaadada ee baytariyada lithium ion.

Waqtigan xaadirka ah, isticmaalka dareeraha ka kooban fluorine iyo waxyaalaha lagu daro ololka ayaa ah jihada muhimka ah ee horumarinta baytariga nooca badbaadada leh ee lithium-ion. Sida loo dheelitiro waxqabadka korantada iyo badbaadada heerkulka sare waxay noqon doontaa diiradda cilmi baarista mustaqbalka. Tusaale ahaan, wax-qabad heersare ah oo isku-dhafan ololka isku-dhafan ee isku-dhafan ee P, N, F, iyo CL ayaa la sameeyay, iyo dareere organic leh oo leh barta karkarinta sare, dhibic sare ayaa la sameeyay, iyo xal elektrolytic ah oo waxqabad badbaado sare leh ayaa la soo saaray.

Dib-u-dhigeyaasha ololka isku-dhafan, laba-shaqo lagu daro waxay sidoo kale noqon doonaan isbeddellada horumarka mustaqbalka. Marka la eego walxaha elektiroonigga ah ee batteriga lithium ion, sifooyinka kiimikaad ee alaabadu way kala duwan yihiin, heerka xasaasiga ah ee walxaha elektiroonigga ah ee dallacaadda iyo ka-soo-saarka awoodda waa mid aan iswaafajin, oo waa wax aan macquul ahayn in la isticmaalo mid ama xaddidan dhowr electrode / electrolyte / daroogo dhammaan naqshadeynta batteriga. Sidaa darteed, mustaqbalka, waa in aan diirada saarno horumarinta hababka baytariyada kala duwan ee qalabka korantada gaarka ah.
