Waxaa la soo wariyay in horraantii Ogosto, warshadaha baabuurta tamarta cusub ay wareysteen Guddoomiyaha BYD Wang Chuanfu ee Hunan Shaoshan Sanji Engineering Work Conference, taas oo sababtay wargeysyada muhiimka ah ee amniga, mareegaha iyo wakiilada, xirfadlayaasha, iyo in ka badan boqol news hal usbuuc gudaheed. Warbixinnada warbaahinta gudaha iyo boqolaal maqaallo ah ayaa sidoo kale soo jiitay indhaha weyn ee suuqa caasimadda. Cufnaanta tamarta runtii ma kordheysaa? Ma lithium iron phosphate mise birta lithium fosfate? Ma wax ma beddeli doonaa? Sababtan awgeed, warbaahinta ayaa wareysatay Dr. Weifeng Fan, agaasimaha farsamada ee Chengdu Xingneng New Materials Co., Ltd., Chengdu Institute of Organic Chemistry, Akadeemiyada Sayniska Shiinaha.

Lithium iron phosphate ma aha kiis gaar ah

ayaa shaaca ka qaaday tignoolajiyada cusub ee BYD ee baytariyada phosphate lithium iron manganese

Dr. Fan waxa uu sheegay in aanay ahayn lithium iron phosphate iyo noocyada kale ee birta ah, fosfat fosfat, iyo bacriminta, ammonium dihydrogen phosphate, ammonium phosphate, iwm) waa isku mid, laakiin xisaabinta milmayn kala duwan, sidaas darteed qof Waxaa laga yaabaa in la yidhaahdo in isticmaalka fosfooraska birta ee lithium iyo bacriminta fosfooraska, laakiin dhab ahaantii, milanka lithium phosphates birta waa mid aad u liidata mana sii deyn karo qaybaha fosfooraska waxtarka leh ee ciidda.

Fan waxa uu aaminsan yahay in kooxaha fosfatiintu ay ka tirsan yihiin nooc kale oo ka mid ah xeryahooda polyanionic (qalabka polyanionic anode), sababtoo ah kooxaha fosfatiintu waxay leeyihiin ion badan oo ogsijiin ah iyo meelo isuduwidda, waxayna inta badan samayn karaan qaab-dhismeed polymer ah oo leh ion birta kala-guurka ah.

Polyanion waa spectrum weyn

Taageeraha dhakhtarku ma laha qiimo sare, M waxay u taagan tahay birta kale ee hore, manganese, cobalt, nikkel, copper, chromium, sida walxo kasta oo bir ah, M waa bir saldhig ah, qaab-dhismeedka kiimikada, ammaan ah in la isticmaalo March iyo kanaalka lithium ion sida Bateriga lithium Anode, laakiin awoodda kala duwan, danab, iyo saamiga waxqabadka, nolosha kala duwan…

Phosphoric acid, lithium iron manganese ama lithium iron manganese, sax?

Dr. Weifeng Fan waxa uu rumaysan yahay in nooc kasta oo cinwaan ahi aanu ahayn mid muhiim ah. Furaha waa saamiga birta iyo manganese. Waqtigan xaadirka ah, ma jiro heshiis cad oo ku saabsan saddexda shay ee la midka ah (532, 111, 811, iwm.). Xaaladdee ayaa ah saamiga ugu muhiimsan ee birta iyo manganese. wanaagsan? Sababtoo ah xasilloonideeda iyo waxqabadkeeda wanaagsan, codsiga dhabta ah ee mustaqbalka wuxuu noqon karaa fosfooraska isku dhafan ee birta ah.

Run ahaantii farsamo ma runbaa?

Awoodda aragtida gaarka ah ee fosfooraska birta ee lithium waa 170mAh/g, jidka dheecaanku waa 3.4V, cufnaanta tamarta maaddaduna waa 578Wh/kg. Awoodda gaarka ah ee phosphate lithium manganese fosfooraska waa 171mAh/g, dariiqa dheecaanku waa 4.1V, cufnaanta maaddaduna waa 701Wh/kg, taas oo 21% ka sarraysa kii hore.

Sida laga soo xigtay Dr. Fan Weifeng, shabakadda baytariga Shiinaha, cufnaanta tamarta ee baytariyada fosfateed ee birta lithium ee jira waa 90Wh/kg-130wh/kg. Marka loo eego 21% hagaajinta cufnaanta tamarta walxaha, xitaa lithium fosfooraska manganese saafiga ah, cufnaanta tamarta waxay gaari kartaa oo kaliya qiyaastii 150Wh / kg, cufnaanta tamarta isticmaalka lithium manganese phosphate batari waxay gaari kartaa oo keliya ka hooseeya 150Wh / kg. Qaadashada baytari fosfateed birta lithium tusaale ahaan, haddii istiraatijiyadda ugu wanaagsan ee mala-awaalka ah (150Wh/kg) la barbar dhigo istiraatijiyadda ugu xun hadda (90Wh/kg), horumarka ugu badan waxaa lagu qiyaasi karaa 67%, laakiin sida cad malahani wuxuu noqon karaa oo keliya mala awaal .
