Lithium iron phosphate dị n&39;ụdị phosphate lithium ore na okike, nwere usoro olivine n&39;usoro. Usoro ihe omimi nke lithium phosphate bụ: LIMPO4, ebe lithium dị mma; ígwè ígwè etiti bụ ọnụ ahịa dị mma; phosphate adịghị mma ọnụ ahịa atọ, nke a na-ejikarị dị ka batrị lithium ihe dị mma. Ngwa nke lithium iron phosphate batrị bụ: akụrụngwa nchekwa ike, ngwa eletriki, ụgbọ ala eletrik, nnukwu ụgbọ ala eletrik, obere akụrụngwa na ike mkpanaka, gụnyere lithium iron phosphate na ụgbọ ala eletrik ọhụrụ nwere ihe ruru 45% nke mkpokọta phosphite.

Nke abụọ, lithium iron phosphate dị ka lithium electrode ihe atụnyere ndị ọzọ lithium batrị nti ihe, olivine Ọdịdị bụ ihe nchebe, gburugburu ebe obibi enyi na enyi, ọnụ ala, ogologo oge, elu okpomọkụ arụmọrụ, wdg, bụ kasị ike lithium ion Otu n&39;ime batrị mma ihe. Ịrụ ọrụ nchekwa bụ igodo PO siri ike na kristal phosphate dị elu, ọ na-esiri ike ire ere, ọ gaghịkwa adaba n&39;usoro ma ọ bụ mepụta oxides siri ike n&39;oge oke na oke okpomọkụ.

Ndụ okirikiri ndụ batrị ogologo acid-acid dị ihe dịka ugboro 300, ndụ ọrụ dị n&39;etiti 1 na 1.5 afọ. Na ọnụ ọgụgụ nke lithium iron phosphate batrị nwere ike iru ihe karịrị 2,000, theoretically na-eji ndụ nke 7-8 afọ.

Igwe ọkụ dị elu na-arụ ọrụ okpomọkụ dị elu nke phosphate na-enweghị ígwè na-ekpo ọkụ ruo 350 ° C ruo 500 Celsius C, ebe lithium manganate na lithium cobaltate dị naanị ihe dịka 200 Celsius. A na-echekarị batrị lithium iron phosphate na gburugburu ebe obibi na ọ nweghị ọla dị arọ na ọla na-adịghị ahụkebe, anaghị egbu egbu, anaghị emetọ ya, bụ batrị gburugburu akwụkwọ ndụ akwụkwọ ndụ zuru oke. The ụgwọ na mwepu usoro nke lithium ígwè phosphate dị ka a nti electrode ihe dị iche na ndị ọzọ ot ihe, na ụgwọ na mwepu nke electrochemical na-egosipụta akụkụ abụọ nke lithium iron phosphate, ụgwọ na ihapu mmeghachi omume bụ dị ka ndị a: Nchaji mmeghachi omume: Ịgbasa mmeghachi omume: Charge, Li + Site LifePO4, Fe2 + tụfuru eletrọn n&39;ime FE3 +; Mgbe ewepụrụ ya, Li + gbanyere n&39;ime iron phosphite n&39;ime LifePo4.

Mgbanwe nke Li + na-eme na Lifepo4 / Fepo4 interface, ya mere, ụgwọ na nkwụsị nkwụsị dị nnọọ larịị, ikike ahụ dịkwa mma karị, dabara adaba maka ihe electrode. Nke atọ, nkwadebe nke lithium iron phosphate nkwadebe nke Efrata na lithium iron phosphate. Ụfọdụ isi iyi lithium nkịtị, isi iyi ígwè, isi iyi carbon, na isi iyi phosphorus bụ ndị a: Nkwadebe nke lithium iron phosphate powder nwere ike imetụta ọrụ ya dị ka ihe dị mma.

Enwere ọtụtụ ụzọ maka nkwadebe nke lithium iron phosphate dị ka mmeghachi omume na-ekpo ọkụ na-ekpo ọkụ dị elu, usoro mbelata carbon thermal, na usoro hydrothermal na-enweghị ihe ọ bụla, ihe ngwọta na-ekpo ọkụ, usoro sol-gel, usoro mmiri ozuzo zuru oke, wdg. 1.
