Ka hadalka xidhmada batteriga qaybaha xudunta u ah-unugga baytariga (1)

Inta badan baytariyada loo isticmaalo xirmooyinka caadiga ah ee suuqa waa baytariyada birta fosfateed lithium.

"Lithium iron fosfate batari", magaca buuxa ee lithium iron fosfate baytari lithium ion batari, magaca aad buu u dheer yahay, loo yaqaan sida lithium birta fosfat batari.Sababtoo ah waxqabadkeedu wuxuu si gaar ah ugu habboon yahay codsiyada tamarta, ereyga "awood" ayaa lagu daraa magaca, taas oo ah, batari awoodda fosfateed ee lithium iron.Waxa kale oo loo yaqaan "bateriga awoodda lithium iron (LiFe).

mabda'a shaqada

Battery fosfateed birta lithium waxa loola jeedaa baytari lithium ion isticmaalaya lithium birta fosfateed sida walxo koronto togan.Qalabka cathode ee baytariyada lithium-ion inta badan waxaa ka mid ah lithium cobalt oxide, lithium manganate, lithium nickel oxide, walxaha ternary, lithium iron fosfate, iwm. .

muhiimadda

Suuqa ganacsiga birta, Cobalt (Co) ayaa ah kan ugu qaalisan, mana jiraan kayd badan, nikkel (Ni) iyo manganese (Mn) way ka jaban yihiin, birta (Fe) ayaa kayd badan leh.Qiimaha alaabta cathode waxay sidoo kale la mid tahay kuwa birahan.Sidaa darteed, baytariyada lithium-ion ee ka samaysan walxaha katoode ee LiFePO4 waa inay ahaadaan kuwo raqiis ah.Sifada kale ee ka mid ah waa in ay deegaan ahaan u wanaagsan tahay oo aan wasakhayn.

Sida batari dib loo dallaci karo, shuruuduhu waa: awood sare, danab sare oo wax soo saar leh, waxqabadka wareegga lacag-bixinta ee wanaagsan, korantada wax-soo-saarka xasilloon, dallacaadda-sare ee hadda jirta, xasilloonida korantada, iyo badbaadada isticmaalka (ma ahan kororka xad-dhaafka ah, qulqulka xad-dhaafka ah iyo gaaban). wareegga).Waxay sababi kartaa gubasho ama qarax ay sabab u tahay hawlgal aan habboonayn), kala duwanaansho heerkul shaqo oo ballaadhan, aan sun ahayn ama ka yar, oo aan wasakhayn deegaanka.baytariyada LiFePO4 isticmaalaya LiFePO4 sida electrode togan waxay leeyihiin shuruudaha waxqabadka wanaagsan, gaar ahaan marka la eego heerka dheecaanka weyn ee dheecaanka (5 ~ 10C dheecaan), danab dheecaan xasilloon, badbaadada (aan guban, aan qarxin), nolosha (wakhtiyada wareegga) ), wax wasakh ah oo deegaanka ah ma jirto, waa kan ugu fiican, oo hadda waa batteriga awoodda wax soo saarka ee ugu fiican.
