Ko te hiko pai ongā pākahiko lithium-ionHe rauemi phosphate rino lithium te mea hanga, he nui ngā painga mō te mahi haumaru me te roa o te huringa. Koinei tētahi o ngā tohu hangarau tino nui o te pākahiko mana. Ka taea te whakatutuki i te roa o te huringa utu me te tukunga o te pākahiko Lifepo4 me te 1C, ka taea te whakatutuki i te 2000 ngā wā, kāore e pahū te poka, kāore e ngāwari te tahu me te pahū ina nui rawa te utu. Mā ngā rauemi cathode phosphate rino lithium ka māmā ake te whakamahi i ngā pākahiko lithium-ion nui-kaha i roto i te raupapa.
Te phosphate rino lithium hei rauemi katote
Ko te pākahiko Lifepo4 e pā ana ki te pākahiko lithium-ion e whakamahi ana i te lithium rino phosphate hei rauemi hiko pai. Ko ngā rauemi hiko pai o ngā pākahiko lithium-ion ko te lithium cobaltate, te lithium manganate, te lithium nickelate, ngā rauemi ternary, te lithium rino phosphate, me ērā atu mea. I roto i ēnei, ko te lithium cobaltate te rauemi hiko pai e whakamahia ana i roto i te nuinga o ngā pākahiko lithium-ion. Ko te tikanga, he tukanga whakauru me te tango i te phosphate rino lithium. He rite tonu tēnei kaupapa ki te lithium cobaltate me te lithium manganate.
Ngā painga o te pākahiko lifepo4
1. Teitei o te whai huatanga o te utu me te tukunga
He pākahiko tuarua lithium-ion te pākahiko Lifepo4. Ko tētahi o ngā mahi matua he pākahiko hiko. He nui ngā painga o tēnei pākahiko i ngā pākahiko NI-MH me Ni-Cd. He nui te whai huatanga o te pākahiko Lifepo4 ki te utu me te tuku, ā, ka taea e te whai huatanga o te utu me te tuku te eke ki te neke atu i te 90% i raro i te āhuatanga tuku, ko te pākahiko waikawa-mata ia e tata ana ki te 80%.
2. pākahiko orapo4 mahi haumaru teitei
He pumau te here PO i roto i te tioata phosphate rino lithium, ā, he uaua ki te pirau, ā, kāore e hinga, e wera rānei pērā i te cobaltate lithium, kāore hoki e hanga he matū waikura kaha ahakoa i te pāmahana teitei, i te uta nui rānei, nō reira he pai te haumaru. I roto i te mahi tuturu, i kitea he wāhanga iti o te tauira he āhua mura i roto i te whakamātautau wero ngira, i te whakamātautau ara iahiko poto rānei, engari kāore he pahūtanga. I roto i te whakamātautau uta nui, i whakamahia he utu ngaohiko teitei he maha ngā wā teitei ake i te ngaohiko tuku-ake-ake, ā, i kitea kei te mau tonu te āhuatanga pahūtanga. Heoi anō, kua tino pai ake te haumaru o tōna uta nui ki te whakataurite ki te pākahiko lithium cobalt oxide wai noa.
3. He roa te huringa o te pākahiko Lifepo4
Ko te pākahiko Lifepo4 e pā ana ki te pākahiko lithium-ion e whakamahi ana i te lithium rino phosphate hei rauemi hiko pai. Ko te ora huringa o te pākahiko waikawa-mata he 300 ngā wā, ā, ko te teitei rawa ko te 500 ngā wā. Ko te ora huringa o te pākahiko mana lithium rino phosphate he neke atu i te 2000 ngā wā, ā, ko te utu paerewa (tere 5-hāora) ka taea te whakamahi tae atu ki te 2000 ngā wā. Ko te pākahiko waikawa-mata kounga rite tonu ko te "haurua tau hou, haurua tau tawhito, tiaki me te tiaki mo te hawhe tau", tae atu ki te 1 ~ 1.5 tau, ā, i raro i ngā tikanga ōrite, ka eke te ora ariā o te pākahiko lifepo4 ki te 7 ~ 8 tau. Ki te whakaarohia whānuitia, ko te ōwehenga utu mahi he nui ake i te whā ngā wā o ngā pākahiko waikawa-mata. Ka taea te utu tere me te tuku i te tukunga au-teitei me te au-teitei 2C. I raro i te rihi motuhake, ka taea te utu katoa i te pākahiko i roto i te 1.5 meneti o te utunga 1.5C, ā, ka taea e te au tīmatanga te eke ki te 2C, engari kāore he mahi pēnei o te pākahiko waikawa-mata.
4. He pai te mahi pāmahana
Ka taea e te pāmahana tino teitei o te phosphate rino lithium te eke ki te 350 °C -500 °C, ko te lithium manganate me te lithium cobaltate he tata ki te 200 °C noa iho. He whānui te whānuitanga pāmahana whakahaere (-20C–+75C), me te ātete ki te pāmahana teitei, ka taea e te tihi whakamahana hiko o te phosphate rino lithium te eke ki te 350 °C-500 °C, ko te lithium manganate me te lithium cobalt oxide he 200 °C anake.
5. Pūhiko Lifepo4 Te kaha teitei
He nui ake tōna kaha i ngā pākahiko noa (waikawa-mata, me ētahi atu). Ko te kaha o te monomer he 5AH-1000AH.
6. Kāore he pānga mahara
Ka mahi ngā pākahiko whakahou i raro i ngā āhuatanga kāore i te tino tukuna, ā, ka tere te heke o te kaha ki raro i te kaha kua whakaritea. Ka kiia tēnei āhuatanga ko te pānga mahara. He rite te mahara ki ngā pākahiko nickel-metal hydride me nickel-cadmium, engari kāore tēnei āhuatanga o te pākahiko lifepo4, ahakoa te āhua o te pākahiko, ka taea te whakamahi me te utu, kāore e hiahiatia te tuku me te utu anō. 7. Te māmā o te pākahiko lifepo4
Ko te kaha o te pākahiko lifepo4 o te whakatakotoranga kotahi he 2/3 o te rōrahi o te pākahiko waikawa-mata, ā, ko te taumaha he 1/3 o te pākahiko waikawa-mata.
8. Ngā pākahiko Lifepo4he hoa taiao
Ko te pākahiko e kiia ana he kore noa iho i ngā konganuku taumaha me ngā konganuku onge (me whakamahi ngā pākahiko Ni-MH i ngā konganuku onge), kāore he paitini (kua whaimanahia e te SGS), kāore e poke, e ai ki ngā ture RoHS a te Pākehā, he tiwhikete pākahiko matomato tūturu. Nō reira, ko te take e paingia ai ngā pākahiko lithium e te umanga he whakaaro nui ki te taiao. Nō reira, kua whakaurua te pākahiko ki te mahere whanaketanga hangarau teitei ā-motu "863" i te wā "Mahere Tau Tekau e Rima" ā, kua noho hei kaupapa tautoko me te whakatenatena matua ā-motu. I te urunga atu o Haina ki te WTO, ka tere te pikinga o te rahinga kaweake o ngā pahikara hiko ki Haina, ā, me whai pākahiko kore poke ngā pahikara hiko e tomo ana ki Ūropi me te Hononga o Amerika. Ko te mahi a te pākahiko lithium-ion e whakawhirinaki ana ki ngā rauemi pai me ngā rauemi kino. Ko te phosphate rino lithium he rauemi pākahiko lithium kua puta noa mai i ngā tau tata nei. Kāore e taea te whakataurite i tōna mahi haumaru me tōna roanga huringa ki ētahi atu rauemi. Ko ngā tohu hangarau tino nui o te pākahiko. He pai ngā painga o te pākahiko Lifepo4, arā, kāore e paitini, kāore e poke, he pai te mahi haumaru, he whānuitanga o ngā rauemi mata, he iti ngā utu, ā, he roa te ora. He rauemi cathode tino pai mō te whakatupuranga hou ongā pākahiko lithium-ion.
