Chiyambi：
Mabatire a Ternary lithiamu ndimabatire a lithiamu chitsulo cha phosphateNdi mitundu iwiri ikuluikulu ya mabatire a lithiamu omwe amagwiritsidwa ntchito kwambiri m'magalimoto amagetsi, makina osungira mphamvu ndi zida zina zamagetsi. Koma kodi mwamvetsa makhalidwe awo ndi kusiyana kwawo? Kapangidwe ka mankhwala awo, makhalidwe awo ogwira ntchito, ndi malo ogwiritsira ntchito ndi osiyana kwambiri. Tiyeni tiphunzire zambiri za iwo ndi Heltec.
Kapangidwe ka zinthu:
Batire ya lithiamu ya Ternary: Zinthu zabwino za electrode nthawi zambiri zimakhala nickel cobalt manganese oxide (NCM) kapena nickel cobalt aluminum oxide (NCA), yomwe imapangidwa ndi nickel, cobalt, manganese kapena nickel, cobalt, aluminiyamu ndi zinthu zina zachitsulo, ndipo electrode yoyipa nthawi zambiri imakhala graphite. Pakati pawo, chiŵerengero cha nickel, cobalt, manganese (kapena aluminiyamu) chingasinthidwe malinga ndi zosowa zenizeni.
Batire ya Lithium iron phosphate: lithiamu iron phosphate (LiFePO₄) imagwiritsidwa ntchito ngati zinthu zabwino za electrode, ndipo graphite imagwiritsidwanso ntchito pa electrode yoyipa. Kapangidwe kake ka mankhwala ndi kokhazikika, ndipo kalibe zitsulo zolemera ndi zitsulo zosowa, zomwe ndizosamala kwambiri zachilengedwe.
Kulipiritsa ndi kutulutsa ntchito:
Batire ya lithiamu ya Ternary: yothamangitsidwa mwachangu komanso yotulutsa mphamvu, imatha kusintha kuti igwirizane ndi mphamvu yamagetsi komanso yotulutsa mphamvu, yoyenera zida ndi zochitika zomwe zimafunikira kwambiri kuti ithamangitsidwe mwachangu, monga magalimoto amagetsi omwe amathandizira kuti ithamangitsidwe mwachangu. Mu malo otentha kwambiri, mphamvu yake yothamangitsidwa ndi yotulutsa mphamvu ndi yabwino, ndipo kutayika kwa mphamvu kumakhala kochepa.
Batire ya phosphate ya chitsulo cha lithiamu: mphamvu yochaja pang'onopang'ono komanso liwiro lotulutsa, koma mphamvu yokhazikika yochaja komanso magwiridwe antchito otulutsa. Imatha kuthandizira kuchaja kwamphamvu kwambiri ndipo imatha kuchajidwa mokwanira mu ola limodzi mwachangu kwambiri, koma mphamvu yochaja ndi kutulutsa nthawi zambiri imakhala pafupifupi 80%, yomwe ndi yotsika pang'ono kuposa ya batri ya lithiamu ya ternary. Pa kutentha kochepa, magwiridwe ake amatsika kwambiri, ndipo mphamvu yosungira mphamvu ya batri ikhoza kukhala 50%-60% yokha.
Kuchuluka kwa mphamvu:
Batire ya lithiamu ya Ternary: Mphamvu yake imakhala yochuluka, nthawi zambiri imafika pa 200Wh/kg, ndipo zinthu zina zapamwamba zimatha kupitirira 260Wh/kg. Izi zimathandiza mabatire a lithiamu ya ternary kusunga mphamvu zambiri pamlingo womwewo kapena kulemera komweko, zomwe zimapangitsa kuti zipangizo zoyendetsera galimoto zikhale kutali, monga magalimoto amagetsi, zomwe zingathandize magalimoto kuyenda mtunda wautali.
Batire ya Lithium iron phosphate: Mphamvu yake ndi yotsika, nthawi zambiri imakhala pafupifupi 110-150Wh/kg. Chifukwa chake, kuti mabatire a lithiamu iron phosphate azitha kuyendetsa bwino, mabatire a lithiamu iron phosphate angafunike kuchuluka kapena kulemera kwakukulu.
Moyo wa kuzungulira:
Batire ya Ternary lithiamu: Nthawi yogwiritsira ntchito nthawi yozungulira ndi yochepa, ndipo nthawi yogwiritsira ntchito nthawi yozungulira ndi pafupifupi 2,000. Pakugwiritsa ntchito kwenikweni, mphamvu yake ikhoza kukhala itawola kufika pa 60% pambuyo pa nthawi 1,000. Kugwiritsa ntchito molakwika, monga kudzaza kapena kutulutsa mphamvu mopitirira muyeso, komanso kugwiritsa ntchito pamalo otentha kwambiri, kudzapangitsa kuti batire iwonongeke mofulumira.
Batire ya Lithium iron phosphate: Imakhala nthawi yayitali, yokhala ndi ma charge ndi discharge cycle opitilira 3,500, ndipo mabatire ena apamwamba amatha kufikira nthawi zoposa 5,000, zomwe zikufanana ndi zaka zoposa 10 zogwiritsidwa ntchito. Ili ndi latisi yabwino yokhazikika, ndipo kuyika ndi kuchotsa ma lithiamu ion sikukhudza kwambiri latisi, ndipo imatha kubwezeretsedwanso bwino.
Chitetezo:
Batire ya lithiamu ya Ternary: kukhazikika kwa kutentha kosakhazikika, kosavuta kuyambitsa kutentha kosasunthika pansi pa kutentha kwakukulu, kudzaza kwambiri, kufupika kwa magetsi ndi zina, zomwe zimapangitsa kuti pakhale chiopsezo chachikulu cha kuyaka kapena kuphulika. Komabe, ndi kupita patsogolo kwa ukadaulo ndi kulimbitsa njira zotetezera, monga kugwiritsa ntchito njira zapamwamba kwambiri zoyendetsera mabatire ndi kukonza kapangidwe ka batire, chitetezo chake chikukulanso nthawi zonse.
Batire ya Lithium iron phosphate: kutentha kwabwino, zinthu zabwino za electrode sizophweka kutulutsa mpweya kutentha kwambiri, ndipo sizingayambe kuwola mpaka 700-800℃, ndipo sizingatulutse mamolekyu a mpweya zikakumana ndi kugundana, kubowola, kufupika kwa magetsi ndi zina, ndipo sizimayaka kwambiri, ndipo sizimayaka kwambiri.
Mtengo:
Batire ya lithiamu ya Ternary: chifukwa chakuti zinthu zabwino za electrode zili ndi zinthu zachitsulo zodula monga nickel ndi cobalt, ndipo zofunikira pakupanga zinthu ndizokwera, ndipo zofunikira pa chilengedwe nazonso ndizokhwima, kotero mtengo wake ndi wokwera.
Batire ya phosphate ya chitsulo cha lithiamu: mtengo wa zipangizo zopangira ndi wotsika, njira yopangira ndi yosavuta, ndipo mtengo wonse uli ndi zabwino zina. Mwachitsanzo, m'magalimoto atsopano amphamvu, mitundu yokhala ndi mabatire a lithiamu iron phosphate nthawi zambiri imakhala yotsika mtengo.
Mapeto
Kusankha batri kumadalira makamaka zofunikira pakugwiritsa ntchito. Ngati mphamvu zambiri komanso nthawi yayitali ya batri ikufunika, mabatire a lithiamu a ternary angakhale chisankho chabwino; ngati chitetezo, kulimba komanso nthawi yayitali ndizofunikira kwambiri, mabatire a lithiamu iron phosphate ndi oyenera kwambiri.
Heltec Energy ndi mnzanu wodalirika mupaketi ya batrikupanga. Popeza tikuyang'ana kwambiri kafukufuku ndi chitukuko, pamodzi ndi zida zathu zambiri za batri, timapereka mayankho amodzi kuti tikwaniritse zosowa zomwe zikusintha zamakampani. Kudzipereka kwathu ku ntchito yabwino kwambiri, mayankho okonzedwa bwino, komanso mgwirizano wamphamvu ndi makasitomala zimatipangitsa kukhala chisankho chabwino kwambiri kwa opanga ndi ogulitsa mabatire padziko lonse lapansi.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, chonde musazengereze kutifunsatitumizireni uthenga.
