Whakahaere wera pākahiko
I te wā e mahi ana te pākahiko, he nui te pānga o te pāmahana ki tana mahi. Mēnā he iti rawa te pāmahana, ka heke te kaha me te mana o te pākahiko, ā, ka poto te ara iahiko o te pākahiko. Kei te piki haere te hiranga o te whakahaere wera o te pākahiko i te mea he teitei rawa te pāmahana, ka pirau pea te pākahiko, ka waikura, ka mura, ka pahū rānei. He mea nui te pāmahana whakahaere o te pākahiko hiko hei whakatau i te mahi, te haumaru me te roa o te ora o te pākahiko. Mai i te tirohanga mahi, ka heke te mahi a te pākahiko mēnā he iti rawa te pāmahana, ka heke te mahi utu me te tuku, ā, ka heke te kaha o te pākahiko. I kitea i te whakatairite, i te hekenga o te pāmahana ki te 10°C, ko te kaha tuku pākahiko he 93% o tērā i te pāmahana noa; heoi, i te hekenga o te pāmahana ki te -20°C, ko te kaha tuku pākahiko he 43% noa iho o tērā i te pāmahana noa.
I roto i ngā rangahau a Li Junqiu me ētahi atu, i kīia mai i te tirohanga haumaru, ki te tino teitei te pāmahana, ka tere ake ngā tauhohenga taha o te pākahiko. Ina tata te pāmahana ki te 60 °C, ka pirau ngā rauemi o roto/ngā matū hohe o te pākahiko, kātahi ka puta te "rerenga wera", ka piki ohorere te pāmahana, tae atu ki te 400 ~ 1000 ℃, ā, ka arahi ki te ahi me te pahūtanga. Ki te tino iti te pāmahana, me pupuri te tere utu o te pākahiko ki te iti iho, ki te kore ka pirau te pākahiko i te lithium ka puta he ara iahiko poto o roto.
Mai i te tirohanga o te roa o te pākahiko, kāore e taea te wareware i te pānga o te pāmahana ki te roa o te pākahiko. Mā te whakatakotoranga o te lithium i roto i ngā pākahiko e ngāwari ana ki te utu i te pāmahana iti ka tere te pirau o te huringa o te pākahiko ki ngā tekau wā, ā, ka pā nui te pāmahana teitei ki te roa o te maramataka me te huringa o te pākahiko. I kitea i roto i ngā rangahau, ina 23 ℃ te pāmahana, ko te roa o te maramataka o te pākahiko me te 80% o te kaha e toe ana he tata ki te 6238 rā, engari ina piki te pāmahana ki te 35 ℃, ko te roa o te maramataka he tata ki te 1790 rā, ā, ina tae te pāmahana ki te 55 ℃, ko te roa o te maramataka he tata ki te 6238 rā. 272 rā anake.
I tēnei wā, nā te utu me ngā herenga hangarau, ko te whakahaere wera o te pākahiko (BTMS) kāore i te kotahi te whakamahinga o ngā pāpāho kawe hiko, ā, ka taea te wehewehe kia toru ngā ara hangarau matua: te whakamatao hau (kaha me te kore mahi), te whakamatao wai me ngā rauemi huringa ā-wāhanga (PCM). He māmā noa te whakamatao hau, kāore he mōrearea o te turuturu, ā, he ohanga. He pai mō te whanaketanga tuatahi o ngā pākahiko LFP me ngā mara waka iti. He pai ake te pānga o te whakamatao wai i te whakamatao hau, ā, ka piki ake te utu. Ki te whakatauritea ki te hau, he āhuatanga o te reo whakamatao wai ko te kaha wera motuhake nui me te tauwehenga whakawhiti wera teitei, e whai hua ana ki te whakakore i te ngoikoretanga hangarau o te iti o te pai o te whakamatao hau. Koinei te arotautanga matua o ngā waka pāhihi i tēnei wā. mahere. I tohu a Zhang Fubin i roto i tana rangahau ko te painga o te whakamatao wai ko te tere o te marara o te wera, ka taea te whakarite i te pāmahana ōrite o te kete pākahiko, ā, he pai mō ngā kete pākahiko he nui te whakaputa wera; ko ngā ngoikoretanga ko te utu nui, ngā whakaritenga takai tino pakari, te mōrearea o te turuturu wai, me te hanganga uaua. He pai te whakawhiti wera me ngā painga utu o ngā rauemi huringa ā-wāhanga, me te iti o ngā utu tiaki. Kei te wāhanga taiwhanga tonu te hangarau o nāianei. Kāore anō kia tino pakari te hangarau whakahaere wera o ngā rauemi huringa ā-wāhanga, ā, koinei te huarahi whanaketanga tino kaha mō te whakahaere wera pākahiko a meake nei.
I te nuinga, ko te whakamatao wai te huarahi hangarau matua o nāianei, nā te mea nui:
(1) I tētahi taha, ko ngā pākahiko toru nikara-nui matua o nāianei he kino ake te pumau o te wera i ngā pākahiko phosphate rino lithium, he iti ake te pāmahana rere wera (te pāmahana pirau, 750 °C mō te phosphate rino lithium, 300 °C mō ngā pākahiko lithium toru), ā, he nui ake te whakaputa wera. I tētahi atu taha, ko ngā hangarau tono phosphate rino lithium hou pērā i te pākahiko mata a BYD me te CTP o Ningde ka whakakore i ngā kōwae, ka whakapai ake i te whakamahinga o te wāhi me te kiato pūngao, ā, ka whakatairanga ake i te whakahaere wera pākahiko mai i te hangarau hau-whakamatao ki te hangarau wai-whakamatao.
(2) Nā te pānga o te aratohu mō te whakaiti i te tahua āwhina me te manukanuka o ngā kaihoko i runga i te tawhiti taraiwa, kei te piki haere tonu te tawhiti taraiwa o ngā waka hiko, ā, kei te piki haere tonu ngā whakaritenga mō te kiato pūngao pākahiko. Kua piki ake te hiahia mō te hangarau whakamatao wai me te pai ake o te whakawhiti wera.
(3) Kei te whanake haere ngā tauira i te huarahi o ngā tauira waenga-ki-teitei, me te tahua utu e ranea ana, te whai i te whakamarie, te iti o te manawanui ki ngā hapa o ngā wāhanga me te mahi teitei, ā, ko te otinga whakamatao wai he pai ake te hangai ki ngā whakaritenga.
Ahakoa he waka tuku iho, he waka hiko hou rānei, kei te piki haere te hiahia o ngā kaihoko mō te whakamarie, ā, kua tino hira te hangarau whakahaere wera o te kokopiti. Mō ngā tikanga whakamatao, ka whakamahia ngā pēhi hiko hei utu mō ngā pēhi noa mō te whakamatao, ā, ka honoa ngā pākahiko ki ngā pūnaha whakamatao hauhautanga. Ko ngā waka tuku iho e whakamahi ana i te momo pereti swash, ko ngā waka hiko hou ia e whakamahi ana i te momo vortex. He tino pai te mahi a tēnei tikanga, he māmā te taumaha, he iti te haruru, ā, he tino hototahi ki te hiko taraiwa. Hei tāpiri, he māmā te hanganga, he pumau te mahi, ā, ko te pai o te rōrahi he 60% teitei ake i te momo pereti swash. %tata. Mō te tikanga whakamahana, ko te whakamahana PTC(Whakamahana hau PTC/Whakamahana whakamatao PTC) e hiahiatia ana, ā, kāore i ngā waka hiko ngā pūtake wera kore utu (pērā i te whakamatao miihini mura ā-roto)
