E kitea ana kua teitei ake te tuanui mō te rāngai pūngao hou i tā te mea i whakaarohia, me te mea kei te ringihia tonu mai te pūtea, te āhua nei kei te rapu i te "Contemporary Amperex Technology" "BYD" rānei e whai ake nei.
Tirohanga Whānui
Ko ngā pākahiko konutai-ion (e kiia nei ko ngā "pākahiko konutai") he momo pākahiko ka taea te whakahou ake e mahi ana mā te whakawhiti i ngā katote konutai i waenga i te katote me te anote i te wā e utu ana, e whakawātea ana hoki. He rite tonu te kaupapa mahi me te hanganga ki ngā pākahiko lithium-ion e whakamahia whānuitia ana.
Nō te rōpū kotahi o ngā huānga te konutai me te lithium, ā, he rite tonu ngā whanonga utu me te tuku hiko "tūru ruru". I te wā e utu ana te pākahiko konutai-ion, ka wehe ngā katote konutai i te katote ka whakauru ki roto i te anode i te wā e haere ana ngā irahiko mā te ara iahiko o waho. Ko te nui ake o ngā katote konutai e whakauru ana ki roto i te anode, ko te teitei ake o te kaha utu. I tetahi atu taha, i te wā e tuku ana, ka hoki ngā katote konutai mai i te anode ki te katote, ka whakanui ake i te kaha tuku i te mea ka neke whakamuri ngā katote konutai.
Kaupapa Mahi
He rite te kaupapa mahi a ngā pākahiko konutai-ion ki te kaupapa mahi a ngā pākahiko lithium-ion, arā, ko te whakaurunga me te tango i ngā katote konutai hei whakatutuki i te whakawhiti utu. I te wā e tukuna ana, ka puta ngā katote konutai i te rauemi anode ka tomo ki te rauemi cathode, me ngā irahiko e rere ana mai i te anode ki te cathode, ka tukuna te pūngao.
I te wā e utu ana, ka wehea ngā iona konutai mai i te rauemi katote ka neke ki roto i te rauemi anode mā te electrolyte, i te wā e rere ana ngā irahiko ki roto i te rauemi anode mā te ara iahiko o waho. Ko te mea pai, ko te whakaurunga me te tango i ngā iona i te wā e utu ana me te tukunga, kaua e whakarerekē i te hanganga o te rauemi, kaua hoki e puta he tauhohenga taha ki te electrolyte. Heoi, kei te anga whakamua ngā hangarau o nāianei ki ngā wero nā te nui ake o te radius o ngā iona konutai, e arahi ana ki ngā huringa hanganga rauemi i te wā e whakaurua ana te iona, ka hua ake he hekenga o te mahi huringa me te pumau.

Te Kīanga Pūngao:Ko te kaha o ngā pūtau pākahiko konutai-ion he 100-150 Wh/kg te tikanga, ko te kaha o ngā pūtau pākahiko lithium-ion he 120-200 Wh/kg te tikanga, ā, ko ngā pūnaha tuatoru nikara-nui he nui ake i te 200 Wh/kg. Ahakoa he iti ake te kaha o ngā pākahiko konutai-ion i tēnei wā ki te whakataurite ki ngā pākahiko lithium tuatoru, ka taea e rātou te taupatupatu, te kapi rānei i te whānuitanga kaha o ngā pākahiko lithium rino phosphate (120-200 Wh/kg) me ngā pākahiko waikawa-mata (30-50 Wh/kg).
Te Awhe Pāmahana Whakahaere me te Haumaru:He whānui te awhe pāmahana e whakahaerehia ana e ngā pākahiko konutai-ion, mai i te -40°C ki te 80°C. He rerekē, ko ngā pākahiko lithium-ion toru te tikanga e whakahaerehia ana i waenga i te -20°C me te 60°C, me te hekenga o te mahi i raro i te 0°C. Ka taea e ngā pākahiko konutai-ion te pupuri i te Āhua Utu (SOC) neke atu i te 80% i te -20°C. Hei tāpiri, nā te ātete ā-roto teitei ake, he iti ake te wera o ngā pākahiko konutai-ion i te wā o ngā ara iahiko poto, ā, he nui ake te haumaru ki te whakataurite ki ngā pākahiko lithium-ion.
Te Whakatau Mahi:Ko te tere o te utu me te tukunga o ngā pākahiko konutai-ion e pā tika ana ki te kaha hekenga o ngā katote konutai i te atanga irahiko-irahiko. Ko ngā āhuatanga e pā ana ki te tere hekenga katote ka pā ki te tere o te pākahiko. Hei tāpiri, he mea nui te tere marara o te wera o roto mō te haumaru me te roa o te ora i te wā e utu ana me te tukunga tere teitei. Nā te hanganga tioata, he pai te tere o te mahi a ngā pākahiko konutai-ion, e pai ai mō te rokiroki pūngao me ngā tono tuku hiko nui.
Tere Utu:Ka taea te utu katoa i ngā pākahiko konutai-ion i roto i te 10 meneti pea, engari ko ngā pākahiko lithium ternary e hiahia ana kia 40 meneti pea, ā, ko ngā pākahiko lithium rino phosphate e hiahia ana kia 45 meneti pea.
