Ndi chiyanilithiamu ironbatire?Chiyambi cha mfundo zogwirira ntchito komanso zabwino za batri yachitsulo ya lithiamu

Lithium iron batri ndi mtundu wa batri m'banja la batire la lithiamu.Dzina lake lonse ndi lithiamu iron phosphate lithiamu ion batri.The cathode zakuthupi makamaka lithiamu iron phosphate.Chifukwa ntchito yake ndiyoyenera kugwiritsa ntchito mphamvu, imatchedwanso "lithium iron power battery".(pambuyo pake amatchedwa "lithium iron batri")

Mfundo yogwira ntchito ya lithiamu iron batri (LiFePO4)
Mapangidwe amkati a batri ya LiFePO4: LiFePO4 yokhala ndi olivine kumanzere imagwiritsidwa ntchito ngati mtengo wabwino wa batri, womwe umalumikizidwa ndi zojambulazo za aluminiyamu ndi mtengo wabwino wa batri.Pakatikati pali chojambula cha polima, chomwe chimalekanitsa mtengo wabwino ndi mtengo woipa.Komabe, lithiamu ion Li + ikhoza kudutsa koma e-electronic e - sangathe.Kumanja ndi mtengo woipa wa batire wopangidwa ndi kaboni (graphite), womwe umalumikizidwa ndi zojambula zamkuwa ndi mtengo woyipa wa batri.Electrolyte ya batri ili pakati pa malekezero apamwamba ndi apansi a batri, ndipo batire imasindikizidwa ndi chipolopolo chachitsulo.

Pamene batire ya LiFePO4 imayikidwa, lithiamu ion Li + mu electrode yabwino imasamukira ku electrode yolakwika kudzera mu membrane ya polima;Panthawi yotulutsa, lithiamu ion Li + mu electrode yolakwika imasamukira ku electrode yabwino kudzera mu diaphragm.Batire ya lithiamu-ion imatchedwa kusamuka kwa ma ion a lithiamu panthawi yolipiritsa ndi kutulutsa.

Kuchita kwakukulu kwa batri ya LiFePO4
The voteji mwadzina wa LiFePO4 batire ndi 3.2 V, mathero mlandu voteji ndi 3.6 V, ndi mapeto kukhetsa voteji ndi 2.0 V. zidzakhala zosiyana.Mwachitsanzo, mphamvu ya batri ya mtundu womwewo (batire wamba mu phukusi lomwelo) ndi yosiyana (10% ~ 20%).

Ubwino walithiamu iron batri
Poyerekeza ndi mabatire achikhalidwe cha lead-acid, mabatire a lithiamu-ion ali ndi zabwino zambiri pakugwiritsa ntchito voteji, kachulukidwe kamphamvu, moyo wozungulira, ndi zina zambiri. kutentha kwakukulu, kutulutsa mphamvu zambiri, moyo wautali wozungulira, kulemera kopepuka, kupulumutsa mtengo wolimbikitsira chipinda cha makina, kukula kochepa, moyo wautali wa batri, chitetezo chabwino, ndi zina zambiri.
