Pa May 16, 4 New Energy Vehicles and Power Battery (CIBF2023 Shenzhen) International Communication Conference inatsegulidwa mwachidwi ku Shenzhen International Convention and Exhibition Center (New Hall).
M’gawo lamwambo wotsegulira, tcheyamani wa msonkhano uno, Academician wa Chinese Academy of Sciences, Ouyang Minggao, anakamba nkhani yaikulu. Anati nthawi zambiri, mabatire a lithiamu iron phosphate amaonedwa kuti ndi otetezeka, ndipo makamaka, izi ndi zoona kwa mabatire ang'onoang'ono a lithiamu iron phosphate. Komabe, kwa mabatire akuluakulu, kutentha kwamkati kumatha kupitirira madigiri 800, omwe amaposa kutentha kwa kuwonongeka kwa zinthu zabwino za elekitirodi za lithiamu iron phosphate.
Kwa mabatire ang'onoang'ono, chifukwa pali mayendedwe a unyolo ndi kugawa, zinthu zabwino za electrode zimangoyamba kuwonongeka zikafika madigiri oposa 500, kotero mabatire ang'onoang'ono sali mkati mwa izi. Koma mabatire akuluakulu a ola la ampere amatha kufika madigiri 700-900, omwe amatha kudutsa ndikudutsa gawo ili, zomwe zimapangitsa kuwonongeka kwa zinthu zabwino za elekitirodi. Tsopano mabatire osungira mphamvu akupitilira maola 300 ampere, zomwe ndi zoopsa kwambiri.
Kuyang'ananso pakupanga mpweya wa lithiamu iron phosphate, hydrogen yopangidwa idzawonjezeka pang'onopang'ono, ndipo ndi kuwonjezeka kwa SOC, hydrogen.zomwe zilindi zoposa 50%, zomwenso ndizowopsa kwambiri. Kuphatikiza apo, poyerekeza zoopsa zoyaka ndi kuphulika kwa mitundu iwiri ya mabatire, index yoyaka komanso yophulika ya mabatire a lithiamu iron phosphate ndi kawiri kuposa mabatire a ternary. Mabatire a Ternary amakonda kuthawa ndipo amayatsa okha. Mabatire a lithiamu iron phosphate sangathe kudziunikira okha, koma chiwopsezo cha kuphulika kwa gasi ndichokwera kuposa cha mabatire a ternary. Ikakumana ndi zowala kunja, imakhala yowopsa kwambiri.
Zathu zatsopano600W, 1200W, ndi 2000W kunyamula mphamvu stationspakali pano ndi apadera pamsika ndipo ndi okhawo omwe amagwiritsa ntchito manganese lifiyamu maselo ang'onoang'ono. Chifukwa chopangira chisankhochi chimadalira ndendende kufunafuna chitetezo. Posankha manganese lifiyamu, zinthu zapaderazi kupanga maselo ang'onoang'ono zofewa paketi, akhoza kuchepetsa kuopsa angathe chitetezo ndi kuonetsetsa kuti angapereke owerenga ndi odalirika zitsimikizo chitetezo mu zochitika zosiyanasiyana ntchito, kupewa zinthu zoopsa monga kuphulika kwa mpweya umene ukhoza kuchitika m'madera ambiri. limodzi ndi lalikulu mphamvu lithiamu chitsulo mankwala mabatire, komanso zoopsa zobisika anabweretsa ndi kudziletsa matenthedwe kuthawira mabatire ternary, motero kupanga mtendere ndi wopanda nkhawa wosuta zinachitikira kwa ogwiritsa.
