Ubwino wa mabatire a lithiamu iron phosphate
1. Kupititsa patsogolo chitetezo cha ntchito
Chomangira cha PO mu lithiamu iron phosphate crystal ndi chokhazikika komanso chovuta kuwola.Ngakhale kutentha kwambiri kapena kuchulukirachulukira, sikungagwere ndikutulutsa kutentha ngati lithiamu cobalt oxide kapena kupanga zinthu zolimba za oxidizing, kotero zimakhala ndi chitetezo chabwino.Lipoti lina linanena kuti mu ntchito yeniyeniyo, chiwerengero chochepa cha zitsanzo chinapezeka kuti chikuwotchedwa mu acupuncture kapena kuyesa kwafupipafupi, koma panalibe kuphulika.kuphulika chodabwitsa.Ngakhale zili choncho, chitetezo chake chochulukiracho chakwera kwambiri poyerekeza ndi mabatire wamba amadzimadzi a electrolyte lithium cobalt oxide.
2. Kuwongolera moyo wautali
Lithium iron phosphate batire imatanthawuza batri ya lithiamu ion yomwe imagwiritsa ntchito lithiamu iron phosphate ngati chinthu chabwino cha electrode.
Mkombero wa moyo wautali mabatire lead-acid ndi nthawi 300, ndipo pazipita nthawi 500, pamene moyo mkombero wa lithiamu chitsulo mankwala mphamvu mabatire akhoza kufika nthawi zoposa 2,000, ndi kulipira muyezo (5 maola mlingo) kugwiritsa ntchito kumatha kufika nthawi 2,000.Batire ya acid-acid yamtundu womwewo ndi "chaka chatsopano, theka la chaka, ndi kukonza ndi kukonza kwa theka la chaka", yomwe ndi 1 ~ 1.5 zaka zambiri, ndipo batri ya lithiamu iron phosphate imagwiritsidwa ntchito mofananamo, moyo wongopeka adzafika 7-8 zaka.Kuganizira mozama, chiŵerengero cha mtengo wa magwiridwe antchito ndi choposa kuwirikiza kanayi kuposa mabatire a lead-acid.Kutulutsa kwakanthawi kochepa kumatha kuyitanitsa mwachangu ndikutulutsa 2C wapano.Pansi pa charger chapadera, batire imatha kulipiritsidwa mkati mwa mphindi 40 pakutha kwa 1.5C, ndipo yoyambira imatha kufika pa 2C, koma mabatire a lead-acid alibe izi.
3. Kuchita bwino kwa kutentha kwapamwamba
Kutentha kwamphamvu kwa lithiamu iron phosphate kumatha kufika 350 ℃-500 ℃, pomwe lithiamu manganate ndi lithiamu cobaltate ndi pafupifupi 200 ℃.Kutentha kwakukulu kogwira ntchito (-20C-75C), ndi kukana kutentha kwambiri, kutentha kwa magetsi kwa lithiamu iron phosphate kumatha kufika 350 ℃-500 ℃, pamene lithiamu manganate ndi lithiamu cobaltate ndizozungulira 200 ℃.
4. Kukhoza kwakukulu
Mabatire nthawi zambiri amagwira ntchito ngati ali ndi chiwongolero chokwanira, ndipo mphamvu yake imatsika mwachangu pansi pa mphamvu yovotera.Chodabwitsa ichi chimatchedwa memory effect.Monga nickel-metal hydride ndi nickel-cadmium mabatire, pali kukumbukira, koma mabatire a lithiamu iron phosphate alibe chodabwitsa ichi.Ziribe kanthu kuti batire ili m'malo otani, imatha kugwiritsidwa ntchito nthawi iliyonse osayitulutsa musanayipire.
5. Kulemera kopepuka
Kuchuluka kwa batire ya lithiamu iron phosphate yokhala ndi mawonekedwe omwewo ndi mphamvu ndi 2/3 ya voliyumu ya batire ya lead-acid, ndipo kulemera kwake ndi 1/3 ya batire ya lead-acid.
6. Kuteteza chilengedwe
Mabatire a Lithium iron phosphate nthawi zambiri amawonedwa kuti alibe zitsulo zolemera ndi zitsulo zosowa (mabatire a nickel-metal hydride amafunikira zitsulo zosowa), zopanda poizoni (zotsimikizika za SGS), zosaipitsa, zimatsatira malamulo aku Europe a RoHS, ndipo ndi mtheradi. satifiketi yobiriwira ya batri.Chifukwa chake, chifukwa chomwe batire ya lithiamu imayamikiridwa ndi makampani makamaka chifukwa choganizira zachitetezo cha chilengedwe.Choncho, batire yaphatikizidwa mu "863" dongosolo lachitukuko chapamwamba cha dziko lonse pa nthawi ya "Mapulani a Zaka Zisanu Zaka khumi", ndipo yakhala ntchito yofunika kwambiri yothandizidwa ndi kulimbikitsidwa ndi boma.Ndi kulowa kwa China mu WTO, kuchuluka kwa njinga zamagetsi ku China kudzakwera kwambiri, ndipo njinga zamagetsi zomwe zimalowa ku Europe ndi United States ziyenera kukhala ndi mabatire osaipitsa.
Komabe, akatswiri ena adanena kuti kuwonongeka kwa chilengedwe komwe kumachitika chifukwa cha mabatire a lead-acid makamaka kumachitika m'njira zosagwirizana ndi kupanga komanso kukonzanso mabizinesi.Momwemonso, mabatire a lithiamu ali m'makampani atsopano a mphamvu, koma sangathe kupeŵa vuto la kuipitsa kwa heavy metal.Mtsogoleri, arsenic, cadmium, mercury, chromium, ndi zina zotero pokonza zitsulo zimatha kumasulidwa kukhala fumbi ndi madzi.Batire palokha ndi mankhwala mankhwala, choncho zingachititse mitundu iwiri ya kuipitsa: mmodzi ndi ndondomeko zinyalala kuipitsidwa mu ntchito yopanga;chinacho ndi kuipitsidwa kwa batri pambuyo pochotsa.
Mabatire a Lithium iron phosphate alinso ndi zofooka zawo: mwachitsanzo, kutentha kwapansi sikuyenda bwino, kachulukidwe wapampopi wa zinthu zabwino zama elekitirodi ndi otsika, ndipo kuchuluka kwa mabatire a lithiamu iron phosphate amphamvu yofanana ndi yayikulu kuposa mabatire a lithiamu ion monga lithiamu. cobalt oxide, kotero ilibe zabwino mu mabatire ang'onoang'ono.Akagwiritsidwa ntchito m'mabatire amphamvu, mabatire a lithiamu iron phosphate, monga mabatire ena, amafunika kukumana ndi vuto la kusasinthasintha kwa batri.
