Lithium baƙin ƙarfe phosphate yana wanzu a cikin nau&39;i na phosphate lithium tama a yanayi, yana da tsari na olivine. Tsarin kwayoyin halitta na lithium phosphate shine: LIMPO4, inda lithium yake tabbatacce; ƙarfe ƙarfe na tsakiya shine farashi mai kyau; phosphate mara kyau ne mai farashin uku, galibi ana amfani da shi azaman kayan ingancin batirin lithium. Aiwatar da batir phosphate na lithium baƙin ƙarfe sune: kayan ajiyar makamashi, kayan aikin lantarki, motocin lantarki masu haske, manyan motocin lantarki, ƙananan kayan aiki da ƙarfin hannu, gami da lithium iron phosphate tare da sabbin motocin lantarki na makamashi yana da kashi 45% na adadin phosphite.

Na biyu, lithium baƙin ƙarfe phosphate a matsayin lithium electrode abu idan aka kwatanta da sauran lithium baturi tabbatacce kayan, olivine tsarin ne mafi amintacce, muhalli abokantaka, arha, dogon lokaci, high zafin jiki yi, da dai sauransu, shi ne mafi m lithium ion Daya daga cikin baturi tabbatacce kayan. Ayyukan aminci shine maɓallin PO mai ƙarfi a cikin lu&39;ulu&39;u-fosfat mai girma, yana da wuya a rugujewa, kuma ba za a rushe shi ba ko samar da oxides mai ƙarfi yayin caji da yanayin zafi.

Rayuwar zagayawa Rayuwar rayuwar batir mai gubar gubar kusan sau 300, rayuwar sabis tana tsakanin shekaru 1 zuwa 1.5. Kuma adadin lithium iron phosphate baturi zai iya kai fiye da 2,000, a ka&39;idar amfani da rayuwa na 7-8 shekaru.

Babban aikin zafin jiki shine matsanancin zafin ƙarfe mara ƙarfe phosphate thermal kololuwa har zuwa 350 ° C zuwa 500 ° C, yayin da lithium manganate da lithium cobaltate kusan 200 ° C ne kawai. Batir lithium baƙin ƙarfe phosphate mai dacewa da muhalli gabaɗaya ana ɗaukarsa baya ƙunshe da ƙarfe masu nauyi da ƙananan karafa, mara guba, mara ƙazanta, cikakken koren muhalli baturi. The caji da fitarwa inji na lithium baƙin ƙarfe phosphate a matsayin tabbatacce electrode abu ne daban-daban daga sauran al&39;ada kayan, da kuma cajin da fitarwa na electrochemical nuna biyu bulan na lithium baƙin ƙarfe phosphate, cajin da fitarwa dauki ne kamar haka: cajin dauki: Fitar dauki: Caji, Li + Daga LifePO4, Fe2 + rasa wani electron a cikin FE3 +; lokacin da aka sallame shi, Li + an saka shi cikin baƙin ƙarfe phosphite zuwa LifePo4.

Canjin Li + yana faruwa a cikin keɓancewar Lifepo4 / Fepo4, don haka cajin caji da lanƙwasa yana da faɗi sosai, yuwuwar kuma ta fi kwanciyar hankali, dacewa da kayan lantarki. Na uku, shirye-shiryen lithium baƙin ƙarfe phosphate shirye-shirye na sinadaran da lithium baƙin ƙarfe phosphate. Wasu tushen lithium na yau da kullun, tushen ƙarfe, tushen carbon, da tushen phosphorus sune kamar haka: Shirye-shiryen foda na baƙin ƙarfe na lithium na iya shafar aikin sa azaman abu mai kyau.

Akwai hanyoyi da yawa don shirya lithium baƙin ƙarfe phosphate, kamar high zafin jiki m lokaci dauki, carbon thermal rage Hanyar, da kuma unminerated hydrothermal Hanyar, fesa thermal bayani, sol - gel Hanyar, jimlar hazo hanya, da dai sauransu. 1. High zafin jiki m lokaci dauki Hanyar high zafin jiki m lokaci dauki hanya ne don shirya lithium baƙin ƙarfe phosphate ne mafi balagagge ci gaban na yanzu ci gaba da kuma mafi yadu amfani hanya.

Bayan tushen baƙin ƙarfe, tushen lithium, tushen phosphorus yana haɗe da mitar sinadarai fiye da gauraye iri ɗaya, a cikin yanayi mara kyau, an fara siyar da shi 5 zuwa 10 h a cikin ƙananan zafin jiki (300 ~ 350 ° C), ta yadda albarkatun ƙasa suka fara bazuwa, sannan a cikin babban zafin jiki (600 ~ 800 ° C) Sintering 10 zuwa 20h lithium fosfat. High zafin jiki m lokaci hanya kira na lithium baƙin ƙarfe phosphate tsari ne mai sauki, shirye-shirye yanayi ne sauki don sarrafa, da hasara shi ne cewa crystal size ne manyan, da barbashi diamita ba sauki don sarrafa, da rarraba ne m, da siffar ne kuma m, da samfurin kewayon matalauta. 2.

Carbonatic thermal rage Hanyar carbon thermal rage Hanyar ne don ƙara carbon kafofin (sitaci, sucrose, da dai sauransu.) a cikin albarkatun kasa hadawa, yawanci amfani da tare da high zafin jiki m lokaci, da kuma carbon source iya rage Fe3 + a high zafin jiki calcination zuwa Fe2 +, Guji da dauki a lokacin da dauki ya zama Fe3 +, sabõda haka, da kira tsari ne mafi m, amma da dauki lokaci ne in mun gwada da kirtani. 3.

Fesa pyrolysis fesa zafi bayani ne mai tasiri wajen samun uniform barbashi size da na yau da kullum siffar lithium baƙin ƙarfe phosphate foda. Precursor shine iri na reactor na 450 zuwa 650 ° C tare da iskar gas, kuma ana samun sinadarin phosphate na lithium bayan halayen zafin jiki. The precursor hazo mai siffar zobe spheroid shirya ta feshi pyrolysis ne high, da barbashi size rarraba ne uniform.

Bayan yanayin zafi mai zafi, ana samun pneumophosphate. Lithium baƙin ƙarfe phosphate Sphere yana da amfani don haɓaka takamaiman yanki na kayan, yana haɓaka ƙarfin rabon ƙarar kayan. 4.

Hanyar dumama ruwa hanya ce ta hada ruwa, tana nufin wani sinadari a cikin jirgin ruwa da aka rufe a cikin jirgin ruwa da aka rufe, kuma ana amsawa da sinadari ta hanyar danyen abu, ana wanke ta ta hanyar tacewa, bushewa bayan bushewa. Lithium iron phosphate za a iya samu bayan da high zafin jiki ne calcined. Shiri na ferrite a hydrothermal Hanyar yana da abũbuwan amfãni daga sauki iko na crystalline tsari da barbashi size, talakawan barbashi diamita, kananan barbashi diamita, sauki tsari, amma bukatar high zafin jiki da kuma high matsa lamba kayan aiki, high cost, rikitarwa tsari rikitarwa.

Baya ga hanyar da ke sama, akwai hanyar hazo gama gari, hanyar sol-gel, hanyar rage oxidative, hanyar bushewa da emulsified, da kuma hanyar sintering microwave. 4. Takaitawa Duk da cewa hanyar shirye-shiryen lithium baƙin ƙarfe phosphate ya fi yawa, sai dai don babban yanayin zafin lokaci mai ƙarfi, mafi yawan matakan binciken dakin gwaje-gwaje.
