Kusungirako mphamvu pogwiritsa ntchito lithiamu iron phosphate battery paketi ndikotetezeka kapena ayi?Pankhani ya mabatire a lithiamu iron phosphate, choyamba tidzakhala ndi nkhawa za chitetezo chake, ndikutsatiridwa ndi ntchito yake.Pogwiritsira ntchito kusungirako mphamvu, kusungirako mphamvu kumafuna chitetezo chapamwamba, moyo wozungulira, mtengo wotsika wa mabatire a lithiamu.Kotero, batire ya lithiamu iron phosphate ndi yotetezeka kapena ayi?Papepalali, XUANLI ikakamiza mkonzi wamagetsi kuti akutengereni kuti mudziwe.
Ku China, ndondomeko zakhazikitsidwanso posachedwa kuti zilimbikitse ndi kuwongolera chitukuko cha kusungirako mphamvu ndikuyika patsogolo zofunikira pamiyezo yoyenera yachitetezo.Kuti mupewe ngozi yamagetsi amagetsi amagetsi amagetsi, zofunikira zatsatanetsatane zimayikidwa patsogolo, kuphatikiza.
(1) sing'anga ndi lalikulu electrochemical mphamvu yosungirako mphamvu chomera sadzasankha ternary lithiamu mabatire, sodium-sulfure mabatire, sayenera kusankha ntchito yachiwiri mphamvu mabatire;
(2) kusankhidwa kwachiwiri kwa mabatire amphamvu, kuyenera kukhala kuwunika kosasinthasintha ndikuphatikizidwa ndi deta yowunikira pakuwunika chitetezo;
(3) chipinda cha zida za batri la lithiamu-ion chikuyenera kukhala chakusanjikiza chimodzi, makamaka kugwiritsa ntchito mtundu wa kanyumba wopangidwa kale.
Kaya ndi dziko lalikulu mphamvu yosungirako dongosolo ntchito mabatire ternary lifiyamu, kapena China panopa mainstay lithiamu chitsulo mankwala, kachitidwe yosungirako mphamvu ayenera kubwerera ku chitetezo chofunika kwambiri, ndiye mwala wapangodya chitukuko.
M'zaka zaposachedwapa, lithiamu chitsulo phosphate luso wakhala okhwima, ndi mabatire ternary lithiamu, lithiamu chitsulo mankwala mabatire alibe kuopsa chitetezo, apamwamba kuposa chitetezo cha mabatire lead-asidi.Zotsatirazi ndi kuyerekezera kwa zinthu zazikulu za lithiamu iron phosphate materials ndi ternary materials.
Monga mukudziwa, batire yogwiritsidwa ntchito posungira mphamvu imafuna moyo wautali, chitetezo chapamwamba komanso mtengo wotsika.Ngakhale kachulukidwe mphamvu ya lithiamu chitsulo mankwala batire ndi otsika, koma mkulu-kutentha ntchito yake, chinthu chofunika kwambiri ndi zabwino matenthedwe bata ndi ntchito zabwino chitetezo, moyo wautali, ndipo pakali pano, kunena, mtengo wake ndi wotsika kuposa ternary.
Pankhani ya zida za ternary, ili ndi mphamvu yayikulu ya gramu komanso nsanja yotulutsa kwambiri, zomwe zikutanthauza kuti kachulukidwe kamphamvu kwambiri.Kutsika kwake kwa kutentha kumakhala bwino, kutentha kwakukulu kumakhala kofala, kukhazikika kwa kutentha kumakhala kofala, chitetezo chimakhalanso chambiri.
Kuchokera pamalingaliro onse, kuchokera pazofunikira zosungira mphamvu zachitetezo chambiri, moyo wautali, mtengo wotsika, lithiamu iron phosphate battery paketi ndiye chisankho chabwino kwambiri cha zida zosungira mphamvu.
Lithium iron phosphate battery pack ili ndi ubwino wa chitetezo ndi kudalirika, moyo wautali wautumiki, phazi laling'ono, ntchito yosavuta komanso yokonza.The mankhwala utenga lithiamu chitsulo mankwala batire selo, amene ndondomeko kupanga utenga kwathunthu zida basi, ndi bwino mankhwala kusasinthasintha, palibe kuphulika ndi moto, amene ndi otetezeka batire selo mu lithiamu batire.
Kuyitanitsa ndi kutulutsa ndi zigawo ziwiri zoyambira zamabatire a lithiamu.Pamene lifiyamu chitsulo mankwala batire kulipiritsa ndi kutulutsa, chifukwa chitsulo ayoni makutidwe ndi okosijeni mphamvu si amphamvu, sangatulutse mpweya, ndi mwachibadwa zovuta zimachitika ndi electrolyte redox anachita, zomwe zimapangitsa lithiamu iron phosphate batire kulipiritsa ndi kutulutsa ndondomeko. malo otetezeka.Osati kokha, lithiamu chitsulo mankwala batire mu lalikulu multiplier kumaliseche, ndipo ngakhale overcharge ndi kutulutsa ndondomeko, n'kovuta zimachitika zachiwawa redox anachita.
Pa nthawi yomweyo, lithiamu mu de-embedding, ndi lattice kusintha kotero kuti selo (gawo laling'ono la kristalo zikuchokera) potsirizira pake kuonda mu kukula, amene basi kuchepetsa kuchuluka kwa voliyumu wa mpweya cathode anachita, kotero. kulipira ndi kutulutsa batire ya lithiamu iron phosphate kumatha kukhalabe kukhazikika kwa thupi, kuchotsa kuthekera kwa kuchuluka kwa voliyumu komanso chodabwitsa cha kuphulika kwa batri.
Kukula kwaukadaulo kwa batri la lithiamu-ion ndikofunikira kwambiri, kokhudzana ndi kukula kwa mtsogolo kwa sikelo ya nthawi yayitali yosungira mphamvu ya lithiamu.Mphamvu yosungirako lifiyamu chitsulo mankwala batire mkulu chitetezo, otsika mtengo, zisathe ndi cholinga wamba chitukuko cha mabizinezi, komanso makampani yosungirako mphamvu akufunika mwamsanga malangizo ofunika kuukira.
