Mabatire a LFP akuwonjezeka

Mwezi watha, Tesla adalengeza zakusintha kwamitundu yonse (yolowera-level) yamagalimoto ake kukhala batire ya Lithium Iron Phosphate (LFP) padziko lonse lapansi.

Lithium iron phosphate batire imatanthawuza batire ya lithiamu-ion yokhala ndi lithiamu iron phosphate ngati zinthu za cathode.Mabatire a Dowell IPACK akunyumba amagwiritsanso ntchito cell ya ATL ya LFP, yomwe ili yoposa mabatire a lithiamu ofanana pamsika.

Ndiye ubwino wa mabatire a LFP ndi chiyani kuposa mabatire ena?

Chitetezo chapamwamba.

Kapangidwe kameneka kamakhala kokhazikika panthawi yolipiritsa ndi kutulutsa, ndipo sikophweka kuphulika ngakhale kutentha kwambiri kapena kuwonjezereka.Poyerekeza ndi batire ya ternary lithiamu, chitetezo chake chimakhala bwino kwambiri.

Moyo wautali wozungulira

Batire yakunyumba ya Dowell's IPACK imatha kufikira mizungu 6000, ndipo moyo wautumiki ukhoza kufikira zaka 10-15.

Kukana kutentha kwambiri

Mabatire a LFP amachita bwino pansi pa kutentha kwakukulu, ndi kutentha kwakukulu kogwira ntchito (-20C--+ 75C).Ndipo imatha kupirira kutentha kwa 350 ° C mpaka 500 ° C, pomwe lithiamu manganete / lithiamu cobalt oxide nthawi zambiri imakhala 200 ° C pozungulira.

Kuthekera kwakukulu komanso kopepuka

Mabatire ambiri a LFP pamsika ali ndi mphamvu zochulukirapo kuposa 90WH/kg, pomwe mphamvu zamabatire a lead-acid ndi pafupifupi 40WH/kg.Komanso, batri ya LFP yofanana ndi kukula kwake ndi magawo awiri pa atatu okha ndi gawo limodzi mwa magawo atatu a kulemera kwa batri ya lead-acid.

Chitetezo cha chilengedwe

Batire ya LFP ilibe zitsulo zolemera kapena zitsulo zosowa.Non-toxic (SGS certified), osaipitsa, mogwirizana ndi malamulo a European RoHS.

Kutha kulipira mwachangu

Kuyambika kwa batire ya lithiamu iron phosphate kumatha kufika 2C, yomwe imatha kuzindikira kuyitanitsa kwakukulu.Mabatire amtundu wa lead-acid ali pakati pa 0.1C ndi 0.2C, omwe sangathe kukwaniritsa zofunikira pakuchapira mwachangu.

Mtengo wochepa wokonza

Mabatire a LFP amatha kuwonjezera moyo wawo wautumiki popanda kukonza mwachangu.Mabatire alibe mphamvu yokumbukira, ndipo chifukwa cha kuchepa kwamadzimadzi (<3% pamwezi), mutha kuwasunga kwa nthawi yayitali.
