Maajo 16-keedii, Baabuurta Tamarta cusub ee 4-aad iyo baytariyada Korantada (CIBF2023 Shenzhen) Shirka Isgaarsiinta Caalamiga ah ayaa si weyn looga furay Xarunta Bandhiga Caalamiga ah ee Shenzhen (Hoolka Cusub).
Qaybta xafladda furitaanka, guddoomiyaha shirkan, Academician Academy of Sciences ee Shiinaha, Ouyang Minggao, ayaa khudbad muhiim ah ka jeediyay. Waxa uu sheegay in guud ahaan, baytariyada fosfooraska birta ee lithium loo arko inay yihiin kuwo badbaado leh, iyo asal ahaan, tani waa run baytariyada fosfateed ee birta lithium yar. Si kastaba ha noqotee, baytariyada awoodda weyn, heerkulka gudaha wuxuu ka badnaan karaa 800 darajo, kaas oo ka sarreeya heerkulka kala-goynta walxaha korantada togan ee fosfatetada birta lithium.
Batariyada yar yar, sababtoo ah waxaa jira falcelin silsilad leh qayb ka mid ah, walxaha korantada togan ayaa laga yaabaa inay bilaabaan inay burburaan marka ay gaaraan in ka badan 500 darajo, markaa baytariyada yaryar kuma jiraan xadkan. Laakiin baytariyada waaweyn ee ampere-hour waxa laga yaabaa inay gaadhaan 700-900 darajo, kuwaas oo laga yaabo inay jabaan oo ay ka gudbaan qaybtan, taasoo keenaysa burburka walxaha korantada togan. Hadda baytariyada kaydinta tamarta asal ahaan waxay ka badan yihiin 300 ampere-saacadood, taas oo weli aad khatar u ah.
Marka la eego soosaarka gaaska ee fosfooraska birta ee lithium, hydrogen-ka la soo saaray ayaa si tartiib tartiib ah u kordheysa, iyo kororka SOC, hydrogennuxurkawaa in ka badan 50%, taas oo iyana aad khatar u ah. Intaa waxa dheer, marka la is barbar dhigo khatarta gubanaysa iyo kuwa qarxa ee labada nooc ee baytariyada, tusaha guban kara iyo kuwa qarxa ee baytariyada fosfateed ee lithium iron waa laba jeer ka baytariyada ternary. Baytariyada ternary waxay u nugul yihiin inay ka cararaan kulaylka oo ay is iftiimiyaan. Baytariyada fosfooraska ee lithium-ka isma iftiimin karaan, laakiin khatarta qaraxa gaasku way ka badan tahay tan baytariyada ternary. Marka ay dibadda la kulanto dhimbiil, waa ka sii khatar badan tahay.
Our cusub ee horumaray600W, 1200W, iyo 2000W awood la qaadan karo stareenshadda waa kuwa gaar ah suuqa waana kuwa kaliya ee isticmaala unugyada yar yar ee lithium manganese. Sababta doorashadan loo sameeyay waxay si sax ah ugu salaysan tahay daba-galka ugu dambeeya ee badbaadada. Adoo dooranaya lithium manganese, walxahan gaarka ah si loo sameeyo unugyo yaryar oo jilicsan, waxay yareyn kartaa khatarta badbaadada ee suurtogalka ah waxayna hubin kartaa inay siin karto dadka isticmaala dammaanad ammaan oo lagu kalsoonaan karo xaaladaha isticmaalka kala duwan, ka fogaanshaha xaaladaha khatarta ah sida qaraxyada gaaska ee laga yaabo inay ku dhacaan meelo waaweyn. baytariyada fosfateed ee lithium ee birta ah ee kali ah iyo kuwa waaweyn, iyo sidoo kale khataraha qarsoon ee ay keeneen is-kuleylka batariyada ternary-ga ah, sidaas darteed abuuraya khibrad isticmaale oo nabad ah oo aan walwal lahayn.
