Kodi ndi chiyanichitsulo cha lithiamuChiyambi cha mfundo yogwirira ntchito ndi ubwino wa batri yachitsulo ya lithiamu

Batire yachitsulo ya Lithium ndi mtundu wa batire m'banja la batire ya lithiamu. Dzina lake lonse ndi batire ya lithiamu iron phosphate lithiamu ion. Zinthu za cathode makamaka ndi lithiamu iron phosphate. Chifukwa chakuti imagwira ntchito bwino kwambiri pamagetsi, imatchedwanso "batire yamphamvu yachitsulo ya lithiamu". (pano imatchedwa "batire yachitsulo ya lithiamu")

Mfundo yogwirira ntchito ya batri yachitsulo ya lithiamu (LiFePO4)
Kapangidwe ka mkati mwa batire ya LiFePO4: LiFePO4 yokhala ndi kapangidwe ka olivine kumanzere imagwiritsidwa ntchito ngati ndodo yabwino ya batire, yomwe imalumikizidwa ndi foil ya aluminiyamu ndi ndodo yabwino ya batire. Pakati pali diaphragm ya polymer, yomwe imalekanitsa ndodo yabwino ndi ndodo yoipa. Komabe, lithiamu ion Li+ imatha kudutsa koma e-electronic e - singathe. Kumanja kuli ndodo yoipa ya batire yopangidwa ndi kaboni (graphite), yomwe imalumikizidwa ndi foil yamkuwa ndi ndodo yoipa ya batire. Electrolyte ya batire ili pakati pa malekezero apamwamba ndi otsika a batire, ndipo batireyo imatsekedwa ndi chipolopolo chachitsulo.

Batire ya LiFePO4 ikachajidwa, lithiamu ion Li+ mu electrode yabwino imasamuka kupita ku electrode yoyipa kudzera mu polymer membrane; Panthawi yotulutsa, lithiamu ion Li+ mu electrode yoyipa imasamuka kupita ku electrode yabwino kudzera mu diaphragm. Batire ya Lithium-ion imatchedwa dzina la kusamuka kwa lithiamu ion panthawi yochajidwa ndi kutulutsa.

Kugwira ntchito kwakukulu kwa batri ya LiFePO4
Voliyumu yodziwika bwino ya batire ya LiFePO4 ndi 3.2 V, voliyumu yomaliza ya charge ndi 3.6 V, ndipo voliyumu yomaliza ya discharge ndi 2.0 V. Chifukwa cha mtundu ndi njira zosiyanasiyana za zipangizo zabwino ndi zoyipa za electrode ndi zipangizo za electrolyte zomwe zimagwiritsidwa ntchito ndi opanga osiyanasiyana, magwiridwe antchito awo adzakhala osiyana pang'ono. Mwachitsanzo, mphamvu ya batire ya mtundu womwewo (batire wamba mu phukusi lomwelo) ndi yosiyana kwambiri (10% ~ 20%).

Ubwino wabatire yachitsulo ya lithiamu
Poyerekeza ndi mabatire achikhalidwe a lead-acid, mabatire a lithiamu-ion ali ndi ubwino waukulu pakugwira ntchito kwa magetsi, kuchuluka kwa mphamvu, moyo wa kuzungulira, ndi zina zotero. Poyerekeza ndi batire yachikhalidwe ya lead-acid, ili ndi ubwino wotsatira: kuchuluka kwa mphamvu, chitetezo champhamvu, kutentha kwabwino, mphamvu yotulutsa, moyo wautali, kulemera kopepuka, kusunga ndalama zolimbitsa chipinda cha makina, kukula kochepa, moyo wautali wa batri, chitetezo chabwino, ndi zina zotero.
