He nui te hiahia mō ngā pākahiko kaha-nui i ēnei rā. He maha ngā whakamahinga o ēnei pākahiko, tae atu ki te pūngao rā, te waka hiko, me ngā pākahiko whakangahau. Ko ngā pākahiko waikawa-mata anake te kōwhiringa kaha-pūhiko teitei i te mākete tae noa ki ētahi tau kua pahure. Heoi, kua tino rerekē te hiahia mō ngā pākahiko lithium i te mākete o nāianei nā ō rātou whakamahinga.

Ko te pākahiko lithium-ion me te lithium Iron phosphate (LiFePO4) te pākahiko e tū motuhake ana i roto i ētahi atu i tēnei āhuatanga. He maha ngā tāngata e pātai ana mō ngā rerekētanga i waenga i ngā pākahiko e rua nā te mea he lithium te pūtake.

Nō reira, ka tirohia hōhonutia ēnei pākahiko i roto i tēnei tuhinga, ā, ka matapakihia hoki ō rātou rerekētanga. Mā te ako i tā rātou mahi i runga i ngā āhuatanga maha, ka nui ake tō māramatanga mō te pākahiko e pai ana mōu. Me tīmata tātou:

He aha i pai ake ai ngā pākahiko LiFePO4:

Ka titiro ngā kaihanga i roto i ngā momo ahumahi ki te phosphate rino lithium mō ngā mahi e matua ana te haumaru. Ko te roa o te mau o te matū me te wera he āhuatanga o te phosphate rino lithium. I roto i ngā taiao wera ake, ka mau tonu te whakamatao o tēnei pākahiko.

Kāore hoki e mura ina kore e tika te whakahaere i te wā e tere ana te utu me te tukunga hiko, ina puta rānei ngā raruraru porowhita poto. Nā te ātete o te phosphate cathode ki te mura, ki te pahū rānei i te wā e nui rawa ana te utu, e wera rawa ana rānei, me te kaha o te pākahiko ki te pupuri i te pāmahana marino, ko te tikanga kāore ngā pākahiko lithium rino phosphate e pāngia e te rere wera.

Heoi, ko ngā painga haumaru o te matū o te pākahiko lithium-ion he iti iho i te nui o ngā painga o te lithium iron phosphate. Tērā pea ka nui ake te pono o te pākahiko nā te mea he nui te kaha o te pūngao, he ngoikoretanga tēnei. Nā te mea he ngāwari te pākahiko lithium-ion ki te rere wera, ka tere ake te mahana i te wā e utu ana. Ko te tango i te pākahiko i muri i te whakamahinga, i te kore mahi rānei, tētahi atu painga o te lithium iron phosphate e pā ana ki te haumaru.

E kiia ana he morearea te matū konutai konutai lithium e whakamahia ana i roto i ngā pākahiko lithium-ion nā te mea ka pāngia te tangata e ngā mate pāwera ki ō rātou kanohi me te kiri. Ina horomia, ka pāngia hoki te tangata e ngā raruraru hauora nui. Nō reira, me āwangawanga motuhake mō te whakakorenga i ngā pākahiko lithium-ion. Heoi, ka taea e ngā kaihanga te whakakore wawe i te konutai rino phosphate nā te mea kāore he paitini.

Ko te hohonutanga o te tukunga mō ngā pākahiko lithium-ion kei waenganui i te 80% ki te 95%. Ko te tikanga me waiho tonu e koe te iti rawa o te 5% ki te 20% o te utu (ka rerekē te ōrau tika i runga i te pākahiko motuhake) i roto i te pākahiko. Ko te hohonutanga o te tukunga o ngā pākahiko lithium rino phosphate (LiFeP04) he tino teitei, arā, 100%. E whakaatu ana tēnei ka taea te tukunga katoa o te pākahiko me te kore e kino. Ko te pākahiko lithium rino phosphate te mea tino pai mō te hohonutanga o te paunga.

He aha te ngoikoretanga nui o te pākahiko Lithium-ion?

Ko te utu me te pono o ngā pūnaha rokiroki pūngao, pērā i ngā mea e whakamahia ana hei pūtake hiko tārua, hei whakaiti rānei i ngā rerekētanga hiko kua whakaputaina mai i ngā pūtake pūngao hou, he mea nui te roa o te mahi a ngā pākahiko. Heoi, he nui ngā ngoikoretanga o ngā pākahiko lithium-ion, tae atu ki ngā pānga tawhito me te tiakitanga.

He iti iho te kaha o ngā pākahiko me ngā pūtau lithium-ion i tō ngā pākahiko rino phosphate lithium. Me tūpato kei nui rawa te utu me te tukunga nui rawa. Hei tāpiri, me pupuri te iahiko i roto i ngā rohe e whakaaetia ana. Nō reira, ko tētahi ngoikoretanga o ngā pākahiko lithium-ion ko te tāpiri i ngā ara iahiko tiaki hei whakarite kia mau tonu i roto i ō rātou awhe mahi haumaru.

He waimarie, nā te hangarau ara iahiko whakauru mamati ka māmā noa te whakauru i tēnei ki roto i te pākahiko, ki te kore rānei e taea te whakawhiti i te pākahiko, ki te taputapu rānei. Ka taea te whakamahi i ngā pākahiko Li-ion me te kore he tohungatanga motuhake nā te whakaurunga o ngā ara iahiko whakahaere pākahiko. Ina kī tonu te pākahiko, ka taea te pupuri tonu i te utu, ā, ka motuhia te hiko o te pākahiko e te rihi.

He pūnaha whakahaere pākahiko ā-roto kei roto i ngā pākahiko lithium-ion e aroturuki ana i ngā āhuatanga maha o tā rātou mahi. Ka whakawhāitihia e te ara iahiko tiaki te ngaohiko teitei rawa o ia pūtau i te wā e utu ana nā te mea ka kino pea ngā pūtau ki te nui rawa o te ngaohiko. Nā te mea kotahi noa te hononga o ngā pākahiko, ka utua raupapatia, ka nui ake te tūponotanga ka whiwhi tetahi pūtau i te ngaohiko teitei ake i te mea e tika ana nā te mea ka hiahiatia he taumata utu rerekē mō ngā pūtau rerekē.

Ka aroturukihia hoki e te pūnaha whakahaere pākahiko te pāmahana o te pūtau hei karo i ngā pāmahana teitei. Ko te nuinga o ngā pākahiko he herenga mōrahi mō te utu me te tukunga i waenga i te 1°C me te 2°C. Heoi, i te wā e tere ana te utu, ka mahana ake ētahi i ētahi wā.

Ko te ngoikore haere o ngā pākahiko lithium-ion i roto i te wā ko tētahi o ngā ngoikoretanga matua o te whakamahinga i roto i ngā taputapu a te kaihoko. Kei te wā, kei te maramataka rānei tēnei, engari kei te maha hoki o ngā huringa tuku-utu kua oti i te pākahiko. He maha ngā wā, ka taea e ngā pākahiko te tu atu ki te 500 ki te 1000 noa iho ngā huringa tuku-utu i mua i te tīmatanga o te hekenga o tō rātou kaha. Kei te piki haere tēnei tau i te whanaketanga o te hangarau lithium-ion, engari ki te mea kua whakauruhia ngā pākahiko ki roto i te mīhini, me whakakapi pea i muri i tētahi wā.

Me pēhea te whiriwhiri i waenga i ngā pākahiko LiFePO4 me te Lithium-ion?

Rino phosphate lithium (LiFePO4) he maha ngā painga o ngā pākahiko ki te whakaritea ki ngā pākahiko lithium-ion. He pai ake te whai huatanga o te tuku me te utu, he roa ake te ora, kāore he tiaki, he tino haumaru, he mama hoki, hei whakahua i ētahi. Ahakoa ehara ngā pākahiko LiFePO4 i roto i ngā mea tino utu iti i te mākete, koinei te haumitanga roa nui rawa atu nā te roa o te ora me te kore tiaki.

I te hohonutanga o te tukunga 80 ōrau, ka taea te whakakī anō i ngā pākahiko lithium rino phosphate tae atu ki te 5000 ngā wā, me te kore e whakaiti i te whai huatanga. Ka taea te whakanui ake i te roa o te mahi o ngā pākahiko lithium rino phosphate (LiFePO4) mā te kore e mahi.

Hei tāpiritanga, kāore he pānga mahara o ngā pākahiko, ā, ka taea te penapena mō te wā roa nā te iti o te tere tukunga-ake (3% ia marama). Me tino tiaki ngā pākahiko lithium-ion. Ki te kore, ka iti haere te roa o te ora.

Ka taea te whakamahi i te 100% o te rahinga utu o ngā pākahiko lithium rino phosphate (LiFePO4). He tino pai hoki ēnei mō ngā momo tono nā te tere o te utu me te tukunga. Ka piki ake te whai huatanga, ā, ka whakaitihia te whakaroa mā te utunga tere. Ka tukuna te mana i roto i ngā pakūnga tere e ngā iahiko tukunga teitei.

Otinga

Kua mau tonu te hiko o te rā i te mākete nā te mea he tino whai hua ngā pākahiko. He tika te kī, mā te otinga rokiroki pūngao pai ake ka hua ake he taiao akuaku, haumaru, me te whai hua. Ka nui ngā painga ka puta mai i ngā taputapu hiko o te rā mā te whakamahi i ngā pākahiko lithium rino phosphate me te lithium-ion.

Heoi anō,LiFePO4He nui ake ngā painga o ngā pākahiko mō ngā kaihoko me ngā kaihoko. He kōwhiringa pai rawa atu te haumi ki ngā teihana hiko kawe me ngā pākahiko LiFePO4 nā te mea he pai ake te mahi, he roa ake te wā e ora ai, ā, he iti ake ngā pānga ki te taiao.
