Ubwino

1. Kupititsa patsogolo chitetezo
Chomangira cha PO mu lithiamu iron phosphate crystal ndi chokhazikika komanso chovuta kuwola.Ngakhale kutentha kwambiri kapena kuchulukirachulukira, sikungagwere ndikupanga kutentha kapena kupanga zinthu zolimba za oxidizing mumtundu womwewo monga lithiamu cobalt oxide, kotero imakhala ndi chitetezo chabwino.Lipoti lina linanena kuti mu ntchito yeniyeni, gawo laling'ono la zitsanzozo linapezeka kuti likuwotchedwa mu acupuncture kapena kuyesa kwafupipafupi, koma palibe kuphulika komwe kunachitika.Pakuyesa kwachabechabe, kulipiritsa kwamagetsi kwambiri komwe kunali kokwera kangapo kuposa voliyumu yodziyimitsa yokha kunagwiritsidwa ntchito, ndipo zidapezeka kuti panalibe chodabwitsa cha Kuphulika.Komabe, chitetezo chake chochulukiracho chakwera kwambiri poyerekeza ndi mabatire wamba amadzimadzi a electrolyte lithiamu cobalt oxide.
2. Kupititsa patsogolo utali wa moyo
Lithium iron phosphate batireamatanthauza batire ya lithiamu-ion yogwiritsa ntchito lithiamu iron phosphate ngati chinthu chabwino cha elekitirodi.
Kuzungulira kwa batire ya lead-acid ya moyo wautali ndi nthawi pafupifupi 300, ndipo yapamwamba kwambiri ndi nthawi 500.Batire ya lithiamu iron phosphate mphamvu ya lithiamu imakhala ndi moyo wozungulira nthawi zopitilira 2000, ndipo mtengo wokhazikika (maola 5) kugwiritsa ntchito kumatha kufika nthawi 2000.Mabatire a asidi amtovu amtundu womwewo amakhala atsopano kwa theka la chaka, akale kwa theka la chaka, komanso kukonza ndi kukonza kwa theka la chaka, osapitilira zaka 1 mpaka 1.5, pomwe mabatire a lithiamu iron phosphate omwe amagwiritsidwa ntchito motere adzakhala ndi moyo wongopeka wa zaka 7 mpaka 8.Poganizira mwatsatanetsatane, chiŵerengero cha mtengo wa ntchito ndi choposa nthawi zinayi kuposa mabatire a lead-acid.Kutulutsa kwakanthawi kochepa kumatha kulipira mwachangu ndikutulutsa 2C yamakono.Ndi charger yodzipatulira, batire limatha kulipiritsidwa mkati mwa mphindi 40 pakutha kwa 1.5C.Mphamvu yoyambira imatha kufika 2C, koma mabatire a lead-acid alibe magwiridwe antchito.
3. Kuchita bwino kwa kutentha kwapamwamba
Kutentha kwamphamvu kwa lithiamu iron phosphate electric heat kumatha kufika 350 ℃-500 ℃, pomwe lithiamu manganate ndi lithiamu cobaltate ndi pafupifupi 200 ℃.Kutentha kosiyanasiyana kogwiritsa ntchito (-20C-75C), ndi kukana kutentha kwambiri, lithiamu iron phosphate electric heat nsonga imatha kufika 350 ℃-500 ℃, pomwe lithiamu manganate ndi lithiamu cobaltate ndizozungulira 200 ℃.
4. Kukhoza kwakukulu
∩Batire loti litha kuchangidwanso likakhala kuti lili ndi chaji chonse osatulutsidwa, mphamvu yake imatsika mwachangu pamtengo woyezedwa.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 mumkhalidwe wotani, imatha kulingidwa ndi kugwiritsidwa ntchito ikangotha.
6, kulemera kopepuka
Kuchuluka kwa batire ya lithiamu iron phosphate yofanana ndi mphamvu ndi 2/3 ya voliyumu ya batire ya lead-acid, ndipo kulemera kwake ndi 1/3 ya batire ya lead-acid.
7. Chitetezo cha chilengedwe
Mabatire a lithiamu iron phosphate nthawi zambiri amawonedwa kuti alibe zitsulo zolemera ndi zitsulo zosowa (batire ya nickel-hydrogen imafuna zitsulo zosowa), zosakhala zapoizoni (SGS certification), osaipitsa, mogwirizana ndi malamulo aku Europe a RoHS, komanso mtheradi. satifiketi yobiriwira ya batri.Chifukwa chake, chifukwa chomwe mabatire a lithiamu-ion amayamikiridwa ndi makampani ndikofunikira chifukwa choganizira zachitetezo cha chilengedwe.Choncho, batireyi yaphatikizidwa mu 863 National High-tech Development Plan pa Gawo la Khumi la Zaka Zisanu ndipo lakhala ntchito yofunika kwambiri yothandizira ndi kulimbikitsa dziko.Chifukwa chakuti dziko langa lilowa m’bungwe la WTO, dziko langa likutumiza njinga za magetsi kunja kwa dziko langa, ndipo njinga zamagetsi zimene zimalowa ku Ulaya ndi ku United States n’zofunika kuti zikhale ndi mabatire osaipitsa.
Komabe, akatswiri ena ananena kuti kuipitsidwa kwa chilengedwe chifukwa cha mabatire a asidi a mtovu kunachitika makamaka chifukwa chakuti kampaniyo imapanga zinthu mwachisawawa ndiponso yowabwezeretsanso.Momwemonso, mabatire a lithiamu-ion ali m'makampani atsopano amagetsi, koma sangathe kuletsa kuwonongeka kwazitsulo zolemera.Mtsogoleri, arsenic, cadmium, mercury, chromium, ndi zina zotero pokonza zitsulo zimatha kumasulidwa kukhala fumbi ndi madzi.Batire palokha ndi mtundu wa mankhwala mankhwala, kotero pakhoza kukhala mitundu iwiri ya kuipitsa: mmodzi ndi kuipitsa ndondomeko chimbudzi mu kupanga zomangamanga;chinacho ndi kuipitsa kwa batriyo itachotsedwa.
Mabatire a Lithium iron phosphate alinso ndi zofooka zawo: mwachitsanzo, kusagwira bwino kwa kutentha, kutsika kwapampopi kwa zinthu za cathode, komanso kuchuluka kwa mabatire a lithiamu-iron phosphate omwe ali ndi mphamvu yofanana ndi yayikulu kuposa mabatire a lithiamu-ion monga lithiamu cobalt oxide, kotero alibe ubwino mu mabatire ang'onoang'ono.Akagwiritsidwa ntchito m'mabatire a lithiamu amphamvu, mabatire a lithiamu iron phosphate ndi ofanana ndi mabatire ena, ndipo amayenera kukumana ndi mavuto osasinthasintha.
