Meesha xigta ee tamarta cusub

Energy storage is considered to be the next outlet for new energy. As a forward-looking technology to promote the development of the new energy industry in the future, the energy storage industry will play a huge role in new energy grid connection, new energy vehicles, smart grids, microgrids, distributed energy systems, and home energy storage systems.

“Sababta horumarinta kaydinta tamarta ayaa ah in korantada sawir-qaadista iyo dabayshu ay yihiin kuwo isdaba-joog ah oo aan xasilloonayn. Sidaa darteed, iskaashiga nidaamyada kaydinta tamarta ayaa loo baahan yahay si loo helo awood deggan oo la isku halayn karo. Agaasimaha Xafiiska Cilmi-baarista Ontology Battery Kaydinta Tamarta, Machadka Cilmi-baarista Awoodda Korontada ee Shiinaha Yang Kai ayaa u sheegay suxufiyiinta.

Isticmaalka tignoolajiyada kaydinta tamarta ee baaxadda weyn waxay kor u qaadi kartaa horumarinta tamarta dib loo cusboonaysiin karo, waxay hagaajin kartaa badbaadada iyo xasiloonida shabkada korantada, waxay wanaajisaa tayada sahayda tamarta, waxayna si wax ku ool ah u yaraynaysaa iska hor imaadka u dhexeeya sahayda korontada iyo baahida.

Nidaamyada kaydinta tamarta ee baaxadda leh waxay dhex maraan dhammaan dhinacyada soo saarista nidaamka tamarta, gudbinta, qaybinta, iyo isticmaalka. Codsigeedu kaliya ma wanaajin karo waxqabadka nidaamyada awooda dhaqameed, laakiin sidoo kale waxay keenaysaa kacaan qorshaynta, naqshadaynta, qaabaynta, hawlgalka iyo maaraynta iyo isticmaalka shabakadaha korantada. Dareenkan, tignoolajiyada kaydinta tamarta waa dhererka amar tignoolajiyadeed oo leh muhiimad istaraatiijiyadeed oo qaran, iyo horumarinta tignoolajiyada kaydinta tamarta ayaa dhab ahaantii “kaydinaysa mustaqbalka.”

“Ubax cajiib ah” oo ku jira baytariyada lithium-ion

Waxaa la fahamsan yahay in tignoolajiyada kaydinta tamarta ay inta badan u qaybsanto kaydinta tamarta makaanikada, kaydinta tamarta korantada, kaydinta tamarta korantada iyo kaydinta tamarta isbedelka wajiga. Sanadihii la soo dhaafay, tignoolajiyada kaydinta tamarta korantada oo ay matalaan baytariyada lithium-ion waxay leedahay astaamaha miisaanka tamarta weyn, xulashada goobta dabacsan, iyo xawaaraha jawaabta degdega ah, kaas oo buuxiya shuruudaha farsamada ee nidaamyada korantada iyo isbeddelka horumarka ee shabakadaha smart, waxaana uu ahaa oo loo arko sida ay diiradda saaraan cilmi-baarista machadyada cilmi-baarista ee dalal kala duwan. Noqo tignoolajiyada kaydinta tamarta kobaca ugu dhaqsaha badan. Baytariyada lithium-ion waa nooc ka mid ah batariyada kursiga ruxaya. Electrodes-ka togan iyo kuwa taban waxay ka kooban yihiin laba isku-dhis ama walxo fudud oo kala saari kara lithium dhowr jeer. Marka la dallaco, walxaha korantada togan waa la tirtiraa, iyo ions lithium waxay galaan electrolyte waxayna dhex galaan kala-soocida si loogu dhejiyo korantada taban. Electrode-ka togan waxa uu maraa falcelin oksaydh ah. Taas lidkeeda waa run inta lagu jiro dheecaanka.

Tiknoolajiyada baytariyada lithium-ion waxay ku jirtay xaalad horumar degdeg ah iyada oo la baarayo walxaha elektiroonigga ah ee baytariga. Hadda waxa ay ka soo korodhay baytariyada lithium cobalt oxide ilaa hababka ternary, lithium manganate, lithium iron phosphate, lithium titanate iyo hababka baytariyada kale ee wada nool. Baytariyada lithium-ion-ka cusub ee leh lithium titanate sida korantada taban waxay jebisaa xaddidaadaha dabiiciga ah ee graphite sida korantada taban, waxayna leedahay wax qabad aad uga fiican marka loo eego baytariyada lithium-ion ee dhaqameed, taasoo ka dhigaysa mid ka mid ah baytariyada kaydinta tamarta ee ugu rajo weyn. Si taas loo gaaro, Yang Kai wuxuu wariyeyaasha u soo bandhigay afar faa’iidooyin oo waaweyn oo ay leeyihiin baytariyada lithium titanate kuwaas oo soo bixi kara:

Badbaadada iyo xasiloonida wanaagsan. Sababtoo ah maaddada lithium titanate anode waxay leedahay awood gelinta lithium sare, abuurista iyo roobabka lithium-ka macdan ayaa laga fogaanayaa inta lagu jiro habka lacag bixinta. Iyo sababta oo ah awooddeeda dheellitirka ah ayaa ka sarreysa awoodda dhimista inta badan dareerayaasha elektrolytka, kuma falceliso elektrolytka mana samaynayso mid adag -Filimka passivation ee dareeraha dareeraha ah wuxuu ka fogaanayaa dhacdooyinka falcelino badan oo dhinac ah, sidaas darteed si weyn ayey u hagaajinaysaa badbaadada . “Xarumaha tamarta kaydinta tamarta waxay la mid yihiin baabuurta korontada, iyo badbaadada iyo xasiloonida ayaa ah tilmaamayaasha ugu muhiimsan.” Yang Kai ayaa yidhi.

Excellent fast charging performance. Too long charging time has always been an obstacle that is difficult to overcome in the development of electric vehicles. Generally, slow-charging pure electric buses are used, and the charging time is at least 4 hours, and the charging time of many pure electric passenger cars is as long as 8 hours. The lithium titanate battery can be fully charged in about ten minutes, which is a qualitative leap from traditional batteries.

Long cycle life. Compared with the graphite materials commonly used in traditional lithium-ion batteries, lithium titanate materials hardly shrink or expand in the framework structure during the process of charging and discharging lithium. / The problem of electrode structure damage caused by cell volume strain when intercalating lithium ions, so it has very excellent cycle performance. According to experimental data, the average cycle life of ordinary lithium iron phosphate batteries is 4000-6000 times, while the cycle life of lithium titanate batteries can reach more than 25000 times.

Waxqabadka wanaagsan ee caabbinta heerkulka ballaaran. Guud ahaan, baabuurta korantada waxay la kulmi doonaan dhibaatooyin marka ay ku dallacaan iyo ku shubayaan at -10 ° C. Baytariyada Lithium titanate waxay leeyihiin iska caabin heerkul ballaaran oo wanaagsan iyo adkeysi xooggan. Waxaa lagu dallaci karaa oo lagu dallaci karaa si caadi ah -40 ° C ilaa 70 ° C, iyada oo aan loo eegin waqooyiga barafaysan, Weli koonfurta kulul, baabuurku ma saameyn doono shaqada sababtoo ah batteriga “naxdin”, isaga oo tirtiraya welwelka isticmaalayaasha .

Waxay si sax ah ugu saleysan tahay faa’iidooyinkan in baytariyada lithium titanate ay noqdeen “yaab” cajiib ah oo ku saabsan horumarinta tignoolajiyada baytariyada lithium-ion.
