, waa baytari lithium ion Mid ka mid ah tilmaamaha cilmi-baarista ee dib-u-warshadaynta elektrolytka, laakiin waxa kale oo jira xaddi badan oo isticmaalka CO2, iyo wakiilka entrained waxa laga yaabaa in ay saamayn ku dib u isticmaalka electrolyte ah. 5 Farsamooyinka soo kabashada walxaha elektiroonigga ah Ka-soo-baxa habka batteriga LIFEPO4, heerka hoos u dhaca ee waxqabadka garaafka taban wuxuu ka weyn yahay maaddada LiFePO4 ee wanaagsan, iyo sababtoo ah qiimaha hooseeya ee garaafiga elektaroonigga ah, qaddarka qaddarku waa yar yahay, soo kabashada ka dibna dhaqaale waa daciif, hadda dib-u-warshadaynta dib-u-warshadaynta ku saabsan korantada xun ee batteriga qashinka. In electrode xun, bireed naxaas ah waa qaali iyo habka soo kabashada waa mid fudud.

Waxay leedahay qiimo soo kabashada sare. Budada garaafka ee la helay ayaa la filayaa inay ku wareegto habaynta baytari wax ka beddel. Zhou Xu et al, baadhista gariir, baadhista gariirka iyo habka isku dhafka kala soocida hawo-mareenka ayaa kala saaraya oo soo kabsaday batari lithium ion wasakh ah qalabka korantada taban.

Habka geeddi-socodka waxaa lagu miiray mashiinka dillaaca dubbe ilaa dhexroor qayb ka yar 1 mm, iyo dillaaca waxaa la dhigayaa saxanka qaybinta sariiraha dareeraha ah si loo sameeyo sariir go&39;an; Furitaanka marawaxada hagaajinaysa heerka socodka gaaska, taas oo u ogolaanaysa sariirta particulate in ay hagaajiso sariirta, Sariirtu waa dabacsan tahay, iyo dareeraha bilowga ah ilaa dareeraha ku filan, birta ayaa laga soocaa qaybaha aan birta ahayn, halkaas oo qaybta iftiinka lagu ururiyo qulqulka hawada, ururinta kala-soocida duufaanka, iyo dib-u-dhiska ayaa lagu hayaa hoosta sariirta dareeraha ah. Natiijooyinku waxay caddeeyeen in ka dib markii la baaro walxaha korantada taban, cabbirka qaybtu waa 92.4% dillaaca cabbirka qayb ka badan 0.

250 mm, iyo darajada toner waa 96.6% oo jajab ah oo ka yar 0.125 mm, waana la soo celin karaa; Waxaa ka mid ah dilaacyada 0.

125-0.250mm, darajada naxaasta waa yar tahay, iyo kala soocida waxtarka leh iyo soo kabashada naxaasta iyo toner waxaa lagu gaari karaa kala soocida socodka gaaska. Waqtigan xaadirka ah, korantada taban waxay inta badan ku saleysan tahay binder aqueous, iyo xiraha waxaa lagu kala diri karaa xal aqueous, walxaha korantada taban iyo bireediyaha naxaasta ururiyaha waxaa lagu kala saari karaa hababka fudud.

Zhu Xiaohui, iwm., waxay soo saartay hab loo isticmaalo aashitada kaaliyaha sare ee ultrasonic iyo soo kabashada qoyan. Xaashiyaha korantada taban waxaa lagu dhejiyaa dareeraha acid hydrochloric, iyo xaashida garaafka tooska ah iyo biibiile naxaas ah oo ururiyaha ah waa la kala soocaa, ururiyaha waa la dhaqay, soo kabashadana waa la gaaray.

Walaxda garaafka waa la sifeeyaa, la qalajiyey, oo la kala miiray si loo helo badeeco garaaf ah oo la soo helay. Alaabta cayriin waxaa lagu xalliyaa wakiilka oksida sida nitric acid, oxidic acid, ka saarida xarunta birta ee walxaha, binder ah, iyo graphite biqilka kooxda functionalized, taasoo keentay in alaabta graphite nadiifinta sare ka dib ururinta qalajinta. Ka dib markii alaabta graphite ee la safeeyey labaad lagu quusiyo xal aqueous yaraynaysaa ee ethylenediamine ama diviniscin, ka dibna ilaalinta nitrogen waxaa kulayl ahaan loo xaliyo si loo hagaajiyo alaabta graphite ah, iyo budada graphite la beddelay ee batteriga la heli karaa.

Electrode-ka taban ee batteriga qashinka ah wuxuu u janjeeraa inuu isticmaalo isku-xidhka aqueous, sidaas darteed walxaha firfircoon iyo foornada naxaasta ah ee xoogga leh ayaa laga saari karaa iyada oo loo marayo hab fudud, iyo soo kabashada caadiga ah ee foornada naxaasta ah ee qiimaha sare leh, qalabka graphite waa la tuuraa waxay keeni doontaa qashinka weyn ee alaabta. Sidaa darteed, horumarinta tignoolajiyada wax ka beddelka iyo hagaajinta qalabka garaafyada, garashada dib-u-isticmaalka agabka garaafka qashinka ee warshadaha batteriga ama qaybaha kale ee warshadaha. 6 Faa&39;iidooyinka dhaqaale ee dib-u-warshadaynta burburka dhaqaale ee lithium birta fosfatetada qashinka soo kabashada baytarigu waxa si weyn u saameeya qiimaha alaabta ceeriin, oo ay ku jiraan qiimaha soo kabashada baytariyada qashinka, qiimaha karboonaytka ceeriin, qiimaha fosfateta birta lithium, iwm.

Isticmaalka dariiqa tignoolajiyada dib-u-warshadaynta qoyan ee hadda la isticmaalo, qiimaha dhaqaale ee ugu badan ee laga helay batteriga phosphate ion qashinka waa lithium, dakhliga soo kabashada waa ilaa 7800 yuan / ton, kharashka soo kabashadana waa ilaa 8,500 yuan / ton, dakhliga soo kabashada lama rogi karo. Kharashka dib-u-warshadaynta, halkaas oo kharashyada soo kabashada fosfooraska birta ee lithium ee kharashyada agabka asalka ah ay yihiin 27%, iyo qiimaha kharashka dheeraadka ah waa 35%. Kharashka alaab-qeybiyeyaasha ayaa muhiim ah oo ay ku jiraan hydrochloric acid, sodium hydroxide, hydrogen peroxide, iwm.

(kor ku xusan xogta isbahaysiga batteriga iyo tartanka) Di la talinta). Isticmaalka waddooyinka tiknoolijiyada qoyan, lithium ma gaari karto dib u soo kabasho dhamaystiran (kabashada lithium inta badan waa 90% ama ka yar), fosfooraska, saameynta soo kabashada birta waa liidata, oo ay isticmaalaan tiro badan oo faa&39;iido leh, iwm, waxaa muhiim ah in la isticmaalo dariiq farsamo qoyan oo adag si loo gaaro faa&39;iidada Original

The batari qashinka fosfate birta lithium isticmaalaa heerkul sare dayactirka hab wajiga adag ama jidka tignoolajiyada dib u cusboonaysiinta, marka la barbar dhigo dariiqa farsamo qoyan, habka soo kabashada ma alkali milmi bireed aluminium dareere ah iyo acid kala diri walax electrode togan lithium birta fosfat iyo tallaabooyinka kale ee habka, sidaas darteed qadarka isticmaalka ee accessories waa weyn. Iska yaree, oo heerkulka sare dayactirka wejiga adag ama jidka tignoolajiyada dib u soo kabashada sare, soo kabashada sare ee lithium, birta iyo fosfooraska canaasiirta waxay yeelan karaan faa&39;iidooyin soo kabashada sare, sida laga filayo Beijing Saidmy, iyadoo la isticmaalayo sharciga dayactirka heerkulka sare Jidka technology dib-u-warshadaynta qaybaha, waxay awoodaan in ay gaaraan ku dhawaad ​​20% faa&39;iido saafi ah. 7 Marka walxaha soo kabashada ay tahay wax ka soo kabasho isku dhafan oo isku dhafan, waxay ku habboon tahay dib u soo kabashada birta iyadoo la adeegsanayo habka roobka kiimikada ama tikniyoolajiyada leaching noolaha, iyo walxaha kiimikaad ee dib loo isticmaali karo, laakiin marka la eego agabka LiFePO4, soo kabashada qoyan ayaa dheer, Si aad u isticmaasho reagents badan oo acid-saldhig ah iyo xalinta tiro badan oo ah dareeraha qashinka acid-saldhigga, waxaa jira cillado qiimo jaban oo qiimo jaban.

Marka la barbar dhigo habka roobka kiimikaad, hagaajinta heerkulka sare iyo farsamooyinka dib u soo celinta heerkulka sare waxay leeyihiin muddo gaaban oo gaaban, iyo qadarka reagent-acid-base waa yar yahay, iyo qadarka qashinka qashinka alkali waa yar yahay, laakiin habka ayaa loo baahan yahay si loo xalliyo ama dib loogu soo celiyo xalinta. Adag oo gudaha ah si looga hortago sifooyinka korantada kiimikaad ee wasakhda ayaa weli saamaynaysa alaabta. Wasakhda waxaa ka mid ah qadar yar oo aluminium ah, bireed naxaas ah, iwm.

Dhibaatada ka sokow, waa dhibaato toos ah, iyo habka dib-u-nooleynta ayaa lagu bartay isticmaalka ballaaran laakiin maaha dhibaato rabitaan. Si loo hagaajiyo qiimaha dhaqaale ee baytariyada qashinka, elektrolytka qiimaha jaban iyo farsamooyinka soo kabashada alaabta elektiroonigga ah waa in la sii horumariyaa, iyo walxaha waxtarka leh ee batteriga qashinka ayaa la kordhiyaa si loo kordhiyo soo kabashada.
