Tan iyo warshadaynta baytariyada lithium-ion ee 1991, graphite waxa ay ahayd sheyga korantada xun ee ugu badan ee baytariyada.Lithium titanate, oo ah nooc cusub oo ah walxaha korantada taban ee baytariyada lithium-ion, ayaa fiiro gaar ah u yeeshay dabayaaqadii 1990-meeyadii sababtoo ah wax qabadkeedii ugu fiicnaa.Tusaale ahaan, walxaha titanate lithium waxay ilaalin karaan xasillooni heer sare ah oo ku jirta qaab-dhismeedkooda crystal inta lagu jiro gelinta iyo ka saarista lithium ions, oo leh isbeddello yar oo joogto ah (isbeddel mug leh).
Maaddadan "eber-ka-soo-baxa" ee korantada waxay si weyn u kordhisaa nolosha wareegga baytariyada lithium titanate.Lithium titanate waxay leedahay kanaalka fidinta lithium ion saddex-geesood ah oo gaar ah oo leh qaab-dhismeedka lafdhabarta, kaas oo leh faa'iidooyin sida sifooyin awood heer sare ah iyo wax qabad heerkul sarreeya oo hooseeya.Marka la barbar dhigo walxaha electrode-ka xun ee kaarboonka, lithium titanate waxay leedahay awood sare (1.55V ka sarraysa lithium bir ah), taas oo keenta lakabka dareeraha adag ee sida caadiga ah ku koray dusha sare ee electrolyte iyo carbon negative electrode oo aan ku samayn dusha lithium titanate. .
Waxa ka sii muhiimsan, way ku adag tahay lithium dendrites inay ku samaysmaan dusha sare ee lithium titanate gudaha xadka korantada ee isticmaalka batteriga caadiga ah.Tani waxay inta badan meesha ka saaraysaa suurtagalnimada wareegyada gaaban ee ay sameeyeen lithium dendrites gudaha baytariga.Markaa badbaadada baytariyada lithium-ion ee leh lithium titanate sida electrode taban ayaa hadda ah kan ugu sarreeya dhammaan noocyada baytariyada lithium-ion ee qoraagu arkay.
Inta badan khubarada warshadaha ayaa maqlay in nolosha wareegga batteriga lithium titanate ee beddelaya graphite maaddaama walxaha korantada taban ay gaari karaan tobanaan kun oo jeer, oo aad uga sarreeya baytariyada caadiga ah ee lithium-ion, waxayna dhiman doontaa ka dib dhowr kun oo wareeg ah .
Sababo la xiriira xaqiiqda ah in inta badan xirfadlayaasha baytariyada lithium-ion aysan waligood bilaabin samaynta alaabada baytariyada lithium titanate, ama ay sameeyeen oo kaliya dhowr jeer oo ay ku dhamaadeen si degdeg ah marka ay la kulmaan dhibaatooyin.Markaa way is dejin waayeen oo si taxadir leh ayay uga fikiri waayeen sababta ugu fiican ee baytariyada lithium-ion-dhaqameed ee sida fiican loo sameeyay ay u dhammayn karaan oo keliya cimriga 1000-2000 oo kharash iyo wareegyo dareere ah?

Ma sababta aasaasiga ah ee nolosha wareegga gaaban ee baytariyada lithium-ion ee dhaqameed sababtoo ah mid ka mid ah qaybaheeda aasaasiga ah - culeyska xishoodka ah ee graphite negative electrode?Marka graphite negative electrode lagu beddelo nooca spinel lithium titanate negative electrode, nidaamka kiimikaad ee baytari lithium-ion asal ahaan isku mid ah waxaa lagu wadi karaa tobanaan kun ama xitaa boqolaal kun oo jeer.
Intaa waxaa dheer, marka dad badani ay ka hadlaan cufnaanta tamarta hoose ee baytariyada lithium titanate, waxay iska indhatiraan xaqiiqo fudud laakiin muhiim ah: nolosha wareegga dheer ee aadka u dheer, badbaadada aan caadiga ahayn, sifooyinka awoodda sare, iyo dhaqaalaha wanaagsan ee baytariyada lithium titanate.Tilmaamahani waxay u noqon doonaan aasaas muhiim u ah warshadaha kaydinta tamarta lithium-ion ee soo baxaya.
Tobankii sano ee la soo dhaafay, cilmi baarista tignoolajiyada baytariga lithium titanate ayaa kor u kacday gudaha iyo dibaddaba.Silsiladdeeda warshadeed waxaa loo qaybin karaa diyaarinta agabka lithium titanate, wax soo saarka baytariyada lithium titanate, is dhexgalka nidaamyada baytariyada lithium titanate, iyo codsiyadooda baabuurta korontada iyo suuqyada kaydinta tamarta.
1. Walaxda lithium titanate
Caalami ahaan, waxaa jira shirkado hormuud u ah cilmi baarista iyo warshadeynta agabka lithium titanate, sida Oti Nanotechnology oo ka socda Mareykanka, Warshadaha Ishihara ee Japan, iyo Johnson&Johnson oo ka socda Boqortooyada Ingiriiska.Waxaa ka mid ah, maaddada lithium titanate ee ay soo saarto titanium-ka Maraykanku waxay leedahay waxqabad aad u fiican marka loo eego heerka, badbaadada, adeegga muddada dheer, iyo heerkulka sare iyo hooseeya.Hase yeeshee, hababka wax-soo-saarka ee aadka u dheer ee saxda ah awgeed, qiimaha wax-soo-saarku waa mid aad u sarreeya, taas oo adkeynaysa in la ganacsado oo kor loo qaado.
