Yintoni i-Anti{0}}i-Corrosion Coatings?
Sichithe iminyaka emithandathu sikhangela ifoyile yomqokeleli yangoku kwiinkqubo zeeseli. Zange nakanye umthengi andicele ukuba ndichaze ukuba kwenziwa ntoni ukugquma ikhabhoni. Basenokuba bayazi okanye abakhathali. Ke le yeyabantu abafike apha bevela kuGoogle kwaye bafuna ukuqonda izinto.
Ifoyile yealuminiyam eqatywe ngekhabhoni. Yiloo mveliso. Ujonge kwifoyile ye-aluminiyam engenanto, mhlawumbi i-12 okanye i-13 ye-microns, kunye ne-carbon layer ebhityileyo kumacala omabini. I-Coating yongeza enye i-micron okanye ezimbini kwicala ngalinye. Ikhabhoni iyaqhuba. Injongo kukukhusela i-aluminium kwi-cathode slurry ngexesha lokwenziwa kweeseli kunye ne-electrolyte ngexesha lokusebenza kweeseli.
Kutheni i-aluminiyam corrodes kwi Li{0}} ion cell ayintsonkothanga. I-LFP slurry iqhuba pH 11 okanye ngaphezulu. I-NMP-esekwe kwi-NCM slurry ayinabundlongondlongo kodwa ayinabuhlobo kwisinyithi esingenanto ekuhambeni kwexesha. Umonakalo wangempela wenzeke kwi-interface phakathi kwezinto ezisebenzayo kunye ne-foil. Ukuhlamba kuqala apho. I-Pitting iba delamination. I-Delamination iba yi-capacity fade kwaye ekugqibeleni ukusilela kwintsimi. Ukutyabeka ngekhabhoni yi-inshurensi etshiphu.
Ndifanele ukukhankanya ubhedu. Icala le-Anode lisebenzisa ifoyile yobhedu. Ubhedu lunemiba eyahlukileyo. Ayifaki i-aluminiyam ngendlela efanayo. Imowudi yokusilela kukupheliswa kumbane ophezulu{4}}ukuba iBMS yakho isikrufu kwaye itshaja ngaphezulu kweseli, iiyoni zobhedu ziyahamba zihambe ziphelele apho zingafanelanga ukuba ziye khona. Ubhedu olugqunyiweyo lukhona. Okuncinci kwimveliso. Abafana beSilicon anode bayayisebenzisa kuba isilicon ibetha isihogo ngaphandle kwefoyile ngexesha lokuhamba ngebhayisekile. Bonke abanye abantu babaleka ubhedu olungenanto kwaye bayibiza ngokuba lusuku.
UDingsheng eZhenjiang mhlawumbi wenza isiqingatha sefoyile yealuminiyam egqunyiweyo iye kwiiseli kwihlabathi liphela. Andinasabelo sabo kanye kwaye andizukwenza inombolo. Makhulu. UWanshun ngomnye umdlali ophambili waseTshayina. Phakathi kwabo babini kwaye mhlawumbi abathathu okanye abane abancinci abancinci, i-China ihambisa uninzi lwezi zinto kwihlabathi jikelele. Amaxabiso aphuma eTshayina aqhuba mhlawumbi nge-15-20% ngaphantsi kwemathiriyeli yaseJapan ngokuxhomekeke kwibakala kunye nokuba ubonisana kangakanani na.
Abathengisi baseJapan basekho. UToyal ebesenza oku ukusukela ngaphambi kokuba uninzi lweenjineli zebhetri zangoku zizalwe. I-UACJ yenza ezinye. Umgangatho awuguquguquki, amaxesha okukhokela amade, kwaye amaxabiso aphezulu. Abenzi beeseli zaseJapan bathenga ifoyile yaseJapan. Wonke omnye umntu ikakhulu uthenga isiTshayina ngaphandle kokuba umthengi wabo unemfuno ethile yokubonelela.
IKorea yingxowa edibeneyo. I-Iljin yenza ifoyile yobhedu kwaye yenza i-copper. Kwi-aluminium, abenzi beeseli zaseKorea bangenisa. Ndikhe ndabona iinkqubo ze-Samsung SDI ezibonisa ifoyile yaseJapan kunye neenkqubo ze-LG ezibonisa ifoyile yaseTshayina kumaqonga eemoto ahlukeneyo kwi-automaker efanayo. Izigqibo zokuthengwa kwempahla kweli nqanaba zibandakanya izinto ezingaphaya kokusebenza kwezinto.
Imveliso yaseMelika-kwaye ndithetha oku njengomntu ozakuzuza kwiinketho ezininzi zasekhaya{1}}ayikafiki. Izibini ezirhafelwayo eziya kuthatha ifoyile yakho engenanto kwaye bayiqhube kumgca wabo. Akukho mveliso edibeneyo kwisikali semoto. Imali yeIRA iyahamba. Izaziso ziyenzeka. Eyona irempu{7}}libali elahlukileyo. Ukuba ufuna umboneleli ofanelekileyo weli -yomthengisi wefoil yebhetri yenkqubo yaseMntla Melika namhlanje, usajonge ngaphesheya kolwandle.
I-coating ngokwayo ayiyonzululwazi ye-rocket. Ikhabhoni emnyama, isibophelelo sePVDF, isinyibilikisi seNMP. Yixube, yombese, yomise, yinqumle. Isithando somlilo esimnyama okanye i-acetylene emnyama kuxhomekeke kumthengisi okhethwayo kunye ne-conductivity ekujoliswe kuyo. Amanye amabakala epremiyamu aphosa igraphene okanye icarbon nanotubes. Intengiso iyayithanda loo nto. Okwenyani -umahluko wokusebenza kwehlabathi ngumda kwiiseli ze-EV eziqhelekileyo. Mhlawumbi imiba yezicelo zexabiso le-4C okanye i-5C. Ipakethi yakho ye-avareji yesithuthi somkhweli ayizukubona.
Okubaluleke ngaphezu koqulunqo lulawulo lwenkqubo. I-Gravure coating yindlela eninzi yokwenza oku. Umqulu okroliweyo uthatha i-slurry, uyidlulisele kwiwebhu ye-foil ehamba ngaphantsi. Ivakala ilula. Ukugcina ubunzima bokugquma ngaphakathi kwe-spec kwiwebhu ye-1200mm kwiimitha ezingama-40 ngomzuzu akukho lula. Imiqulu yeGravure iyanxiba. I-viscosity ye-slurry itshintsha phezu kwebhetshi. Utshintsho lobushushu luchaphazela ukudluliselwa. I-li{10}}yomthengisi wezixhobo zebhetri angakubonisa amaqashiso amabini kumboneleli ofanayo, i-SKU efanayo, kwaye enye iya kuba nokuphindwe kabini ukuguquguquka kobuninzi benye.
Ukuphathwa kwewebhu yintloko yayo. Ifoyile yeAluminiyam le iinyembezi zibhityileyo. Ikhefu lewebhu lithetha ixesha lokuphumla, ukuchithwa, kunye nelahleko yesivuno. Abafana abaneminyaka besenza le nto baye bafowunela iiprofayili zabo zoxinzelelo. Abangeneli abatsha bafunda izifundo ezibizayo. Omnye umthengisi waseTshayina andizukubiza igama elilahlekileyo kwiinyanga ezintathu zemveliso ezama ukumisela umgca omtsha wokugquma ngenxa yokuba abakwazanga ukugcina iwebhu ingaphuki.
Amaphepha akhethekileyo acela ubunzima bokugquma kwi-gsm, ukumelana nomphezulu kwi-milliohms kwisikwere ngasinye, amandla okuncamathela ngovavanyo lwe-crosshatch. Loo manani akho ngenjongo yokufaneleka. Usuku-ukuya{3}}kusuku, eyona nto bayikhathaleleyo abenzi beeseli kukuhambelana okuninzi. Ukuba uxhathiso lwakho lu 15 milliohms kwiqashiso enye kunye ne 25 kwelandelayo, oko kubonisa njenge cell - ukuya{8}}kutshintsho lweseli kwiipakethi ezigqityiweyo. Ii-OEMs zeemoto zithiyile ukwahluka. Amaqabane e-OEM e-li{11}}yabo ibhetri ayithiyileyo ukuchaza umahluko. Wonke umntu uyayilandela emva kwexesha.
Ndibone iinkqubo ziwisa umthengisi wefoyile ngaphezulu kwento enye embi eyenze ukuba ibe ziiseli zemveliso. Ubudlelwane bubalulekile kweli shishini. Ukufaneleka kuthatha iinyanga. Akukho mntu ufuna ukufaneleka. Ke ababoneleli abahambisa imathiriyeli engaguqukiyo bagcina ishishini labo. Ababoneleli abangatshintshwayo ngokuzolileyo.
Ilizwe eliqinileyo-liyeza ekugqibeleni. Ii-electrolyte zesulfide zizisa ikhemistri entsha engakhange yenzelwe i-carbon coatings. I-oksidi kunye ne-polymer electrolytes ayinangxaki encinci. Iiseli eziqinileyo-zikwimveliso okanye kufutshane nemveliso-kwaye azikho zininzi{6}}inkoliso ezisebenzisa iikhemistri apho iityayimbo eziqhelekileyo zisebenza kakuhle. Ukuba i-sulfide{8}esekelwe kwiiseli zikhe zabetha umthamo, ukhuseleko lwangoku lomqokeleli luya kufuna isisombululo esahlukileyo. I-ALD alumina, mhlawumbi. Izithintelo zeFluoropolymer. Akukho mntu wenze isikali ngenxa yokuba iiseli ngokwazo azikanyuswanga.
Okwangoku, i-carbon coated foil ihlala injalo iminyaka engamashumi amabini. Kuyadika. Kuyimfuneko. Into yomgca kwi-BOM yokuba ukuthenga kuzama ukuhla kwaye ubunjineli buzama ukungacingi malunga nokuba kukho into engalunganga.
Iili{0}}iion ezintlanu zebhetri abasasazi base-US banokukufumana iisampulu phakathi kweveki. Ukufumana umntu onokuqinisekisa ulwabiwo lwenkqubo ye-50 GWh kunzima. Esona sinyanzelo sesixokelelwano sonikezelo kweli candelo. Hayi iteknoloji. Ukuzinikela kwisikhundla.
