Chiyambi:
Ternary lithiamu mabatire ndilithiamu iron phosphate mabatirendi mitundu iwiri ikuluikulu ya mabatire a lithiamu omwe amagwiritsidwa ntchito kwambiri pamagalimoto amagetsi, makina osungira mphamvu ndi zipangizo zina zamagetsi. Koma kodi mwamvetsa makhalidwe awo ndi kusiyana kwawo? Mapangidwe awo amankhwala, mawonekedwe a magwiridwe antchito ndi magawo ogwiritsira ntchito ndizosiyana kwambiri. Tiyeni tiphunzire zambiri za iwo ndi Heltec.
Zofunika:
Ternary lifiyamu batire: zabwino elekitirodi zakuthupi zambiri faifi tambala cobalt manganese okusayidi (NCM) kapena faifi tambala cobalt aluminium okusayidi (NCA), amene wapangidwa faifi tambala, cobalt, manganese kapena faifi tambala, cobalt, zotayidwa ndi zinthu zina zitsulo oxides, ndi zoipa electrode nthawi zambiri ndi graphite. Pakati pawo, chiŵerengero cha faifi tambala, cobalt, manganese (kapena zotayidwa) akhoza kusintha malinga ndi zosowa zenizeni.
Lifiyamu chitsulo mankwala batire: lithiamu chitsulo mankwala (LiFePO₄) ntchito ngati zabwino elekitirodi zakuthupi, ndi graphite amagwiritsidwanso ntchito kwa elekitirodi zoipa. Kapangidwe kake kake kamakhala kokhazikika, ndipo kalibe zitsulo zolemera ndi zitsulo zosowa, zomwe zimateteza chilengedwe.
Kulipira ndi kutulutsa ntchito:
Ternary lithiamu batire: kuthamanga mofulumira ndi kutulutsa kuthamanga, kungathe kusinthasintha kwapamwamba pakali pano ndi kutulutsa, koyenera zipangizo ndi zochitika zomwe zimakhala ndi zofunikira zothamanga mofulumira, monga magalimoto amagetsi omwe amathandizira kuthamanga mofulumira. M'malo otentha otsika, ntchito zake zolipiritsa ndi zotulutsa zimakhalanso zabwino, ndipo kutaya mphamvu kumakhala kochepa.
Lithium iron phosphate batire: Kuthamanga kwapang'onopang'ono komanso kuthamanga kotulutsa, koma kukhazikika kozungulira komanso magwiridwe antchito. Itha kuthandizira kulipiritsa kwamtengo wapamwamba ndipo imatha kulipiritsidwa kwathunthu mu ola la 1 mwachangu kwambiri, koma kuyendetsa bwino ndi kutulutsa kumakhala kozungulira 80%, komwe kumakhala kotsika pang'ono kuposa batri ya ternary lithiamu. Pansi pa kutentha kochepa, ntchito yake imachepa kwambiri, ndipo mphamvu yosungira mphamvu ya batri ikhoza kukhala 50% -60%.
Kuchuluka kwa mphamvu:
Ternary lithiamu batire: Kuchulukitsitsa kwa mphamvu kumakhala kwakukulu, nthawi zambiri kumafika kupitirira 200Wh/kg, ndipo zinthu zina zapamwamba zimatha kupitilira 260Wh/kg. Izi zimathandiza mabatire a ternary lithiamu kusunga mphamvu zambiri pa voliyumu imodzi kapena kulemera kwake, kupereka maulendo atali oyendetsa zipangizo, monga magalimoto amagetsi, omwe angathandize magalimoto kuyenda mtunda wautali.
Lithium iron phosphate batire: Kuchuluka kwa mphamvu kumakhala kochepa, nthawi zambiri kumakhala 110-150Wh/kg. Chifukwa chake, kuti mukwaniritse zoyendetsa zomwezo monga mabatire a ternary lithiamu, mabatire a lithiamu iron phosphate angafunike voliyumu yayikulu kapena kulemera.
Moyo wozungulira:
Batire ya Ternary lithiamu: Moyo wozungulira ndi waufupi, wokhala ndi chiwerengero chozungulira pafupifupi nthawi 2,000. Pakugwiritsa ntchito kwenikweni, mphamvuyo imatha kuwonongeka mpaka pafupifupi 60% pambuyo pa mizungu 1,000. Kugwiritsa ntchito molakwika, monga kuthira mochulukira kapena kutulutsa, ndikugwiritsa ntchito m'malo otentha kwambiri, kumathandizira kuwola kwa batri.
Batire ya Lithium iron phosphate: Moyo wautali wozungulira, wokhala ndi maulendo opitilira 3,500 ndikutulutsa, ndipo mabatire ena apamwamba amatha kufikira nthawi zopitilira 5,000, zomwe ndizofanana ndi zaka 10 zogwiritsidwa ntchito. Ili ndi kukhazikika kwa lattice yabwino, ndipo kuyika ndi kuchotsedwa kwa ma ion a lithiamu sikungakhudze pang'ono pa latisi, ndipo kumakhala bwino kusinthika.
Chitetezo:
Ternary lithiamu batire: kusakhazikika kwamafuta, kosavuta kuyambitsa kuthawa kwamafuta pansi pa kutentha kwakukulu, kuchulukirachulukira, kufupika kwafupi ndi zina, zomwe zimapangitsa kuti pakhale chiopsezo chachikulu cha kuyaka kapena kuphulika. Komabe, ndi kupita patsogolo kwaukadaulo komanso kulimbikitsa njira zotetezera, monga kugwiritsa ntchito njira zotsogola za batri komanso kukhathamiritsa kwa mawonekedwe a batri, chitetezo chake chimakhalanso bwino nthawi zonse.
Lithium chitsulo mankwala batire: zabwino matenthedwe bata, zabwino elekitirodi zakuthupi n'zosavuta kumasula mpweya pa kutentha, ndipo sangayambe kuwola mpaka 700-800 ℃, ndipo sadzamasula mamolekyu okosijeni pamene ikukhudza, puncture, dera lalifupi ndi zina, ndipo si sachedwa kuyaka zachiwawa, ndi mkulu chitetezo ntchito.
Mtengo:
Ternary lifiyamu batire: chifukwa zabwino elekitirodi zakuthupi muli zinthu zitsulo mtengo monga faifi tambala ndi cobalt, ndi zofunika ndondomeko kupanga ndi mkulu, ndi zofunika zachilengedwe ndi okhwima, choncho mtengo ndi mkulu.
Lithium iron phosphate batire: mtengo wa zinthu zopangira ndi wochepa kwambiri, kupanga ndi kosavuta, ndipo mtengo wonse uli ndi ubwino wina. Mwachitsanzo, m'magalimoto amagetsi atsopano, zitsanzo zokhala ndi mabatire a lithiamu iron phosphate nthawi zambiri zimakhala zotsika mtengo.
Mapeto
Kusankhidwa kwa batri kumadalira makamaka zofunikira za ntchito. Ngati kuchulukitsitsa kwamphamvu kwamphamvu komanso moyo wautali wa batri umafunika, mabatire a ternary lithiamu angakhale chisankho chabwinoko; ngati chitetezo, kulimba ndi moyo wautali ndizofunikira kwambiri, mabatire a lithiamu iron phosphate ndi abwino kwambiri.
Heltec Energy ndi mnzanu wodalirikabatire paketikupanga. Ndi kuyang'ana kwathu kosalekeza pa kafukufuku ndi chitukuko, pamodzi ndi mitundu yosiyanasiyana ya zida za batri, timapereka mayankho okhazikika kuti tikwaniritse zosowa zamakampani. Kudzipereka kwathu pakuchita bwino, mayankho ogwirizana, ndi mgwirizano wamphamvu wamakasitomala zimatipangitsa kukhala osankha kwa opanga mapaketi a batri ndi ogulitsa padziko lonse lapansi.
Ngati muli ndi mafunso kapena mukufuna kudziwa zambiri, musazengereze kuterokufikira kwa ife.
