ʻEkolu mau ʻano nui onā pākahi lithium-ion(li-ion): nā pūnaewele cylindrical, nā pūnaewele prismatic, a me nā pūnaewele pouch.I ka ʻoihana EV, ʻo nā mea hoʻomohala maikaʻi loa e hoʻopuni ana i nā cell cylindrical a prismatic.ʻOiai ʻo ke ʻano pākaukau cylindrical ka mea kaulana loa i nā makahiki i hala iho nei, ua manaʻo kekahi mau mea e hiki ke lawe i nā cell prismatic.

He ahaNā Pūnaewele Prismatic

Apūʻali prismatiche cell nona kemika i hoʻopaʻa ʻia i loko o kahi pahu paʻa.Hiki i kona ʻano ʻāpana ʻehā ke hoʻopaʻa pono i nā ʻāpana he nui i loko o kahi module pākahi.ʻElua ʻano o nā pūnaewele prismatic: ʻo nā pepa electrode i loko o ka pahu (anode, separator, cathode) i hoʻopaʻa ʻia a ʻōwili ʻia a palahalaha.

No ka leo like, hiki i nā cell prismatic i hoʻopaʻa ʻia ke hoʻokuʻu i ka ikehu hou aʻe i ka manawa hoʻokahi, e hāʻawi ana i ka hana ʻoi aku ka maikaʻi, ʻoiai nā cell prismatic flattened i ʻoi aku ka ikehu, e hāʻawi ana i ka lōʻihi.

Hoʻohana nui ʻia nā cell Prismatic i nā ʻōnaehana mālama ikehu a me nā kaʻa uila.ʻO ko lākou nui nui e lilo lākou i mau moho maikaʻi ʻole no nā mea liʻiliʻi e like me ka e-bikes a me nā kelepona.No laila, ʻoi aku ka maikaʻi o lākou no ka hoʻohana ʻana i ka ikehu.

He aha ke ano o na Cell Cylindrical

Apuʻupuʻu cylindricalhe keena i hoʻopaʻa ʻia i loko o ke kini pōʻaiapili paʻa.He liʻiliʻi a poepoe nā cell cylindrical, e hiki ai ke hoʻopaʻa iā lākou i nā mea like ʻole.ʻAʻole like me nā ʻano pākaukau ʻē aʻe, pale ko lākou ʻano i ka pehu ʻana, kahi mea i makemake ʻole ʻia i loko o nā pila kahi e hōʻiliʻili ai nā kinoea i loko o ka pahu.

Ua hoʻohana mua ʻia nā cell cylindrical i loko o nā kamepiula, aia ma waena o ʻekolu a ʻeiwa mau kelepona.A laila ua loaʻa iā lākou ka kaulana i ka wā i hoʻohana ai ʻo Tesla iā lākou i kāna mau kaʻa uila mua (ke Roadster a me ka Model S), aia ma waena o 6,000 a me 9,000 mau kelepona.

Hoʻohana pū ʻia nā cell cylindrical i nā e-bikes, nā mea lapaʻau, a me nā satelite.He mea koʻikoʻi nō hoʻi lākou i ka ʻimi ʻana i ka lewa ma muli o ko lākou ʻano;e hoʻopōʻino ʻia nā ʻano kelepona ʻē aʻe e ke kaomi o ka lewa.ʻO ka Rover hope loa i hoʻouna ʻia ma Mars, no ka laʻana, e hoʻohana ana i nā cell cylindrical.Hoʻohana nā kaʻa heihei uila kiʻekiʻe Formula E i nā pūnaewele like me ka rover i kā lākou pākaukau.

ʻO nā ʻokoʻa nui ma waena o nā kelepona prismatic a me nā cylindrical

ʻAʻole ʻo ke kino wale nō ka mea e hoʻokaʻawale ai i nā cell prismatic a me nā cylindrical.ʻO nā ʻokoʻa koʻikoʻi ʻē aʻe e pili ana i ko lākou nui, ka helu o nā pili uila, a me kā lākou mana mana.

Nui

ʻOi aku ka nui o nā cell prismatic ma mua o nā cell cylindrical a no laila ʻoi aku ka nui o ka ikehu ma kēlā me kēia cell.No ka hāʻawi ʻana i ka manaʻo koʻikoʻi o ka ʻokoʻa, hiki i kahi cell prismatic hoʻokahi ke loaʻa i ka nui o ka ikehu me 20 a 100 cylindrical cell.ʻO ka liʻiliʻi liʻiliʻi o nā cell cylindrical ʻo ia ka mea hiki ke hoʻohana ʻia no nā noi e pono ai ka mana liʻiliʻi.ʻO ka hopena, hoʻohana ʻia lākou no kahi ākea ākea o nā noi.

Hoʻohui

No ka mea ʻoi aku ka nui o nā cell prismatic ma mua o nā cell cylindrical, ʻoi aku ka liʻiliʻi o nā cell no ka loaʻa ʻana o ka nui o ka ikehu.'O ia ho'i, no ka leo ho'okahi, 'oi aku ka li'ili'i o nā pilina uwila e pono e wili 'ia nā 'a'a e ho'ohana ana i nā pūnaewele prismatic.He pōmaikaʻi nui kēia no nā cell prismatic no ka mea he liʻiliʻi nā manawa kūpono no ka hana ʻana i nā hemahema.

Ka mana

Hiki i nā pūnaewele cylindrical ke mālama i ka ikehu liʻiliʻi ma mua o nā pūnaewele prismatic, akā ʻoi aku ko lākou mana.'O ia ho'i, hiki i nā pūnaewele cylindrical ke ho'oku'u i ko lākou ikehu ma mua o nā pūnaewele prismatic.ʻO ke kumu, ʻoi aku ka nui o nā pilina i kēlā me kēia amp-hola (Ah).ʻO ka hopena, kūpono nā cell cylindrical no nā noi hana kiʻekiʻe aʻo nā cell prismatic ka mea kūpono e hoʻonui i ka ikehu.

ʻO ka laʻana o nā noi pākaukau hana kiʻekiʻe e pili ana i nā kaʻa heihei Formula E a me ka helikopter Ingenuity ma Mars.Pono nā mea ʻelua i nā hana koʻikoʻi ma nā kaiapuni koʻikoʻi.

No ke aha e lawe ʻia ai nā Cell Prismatic

Ke ulu wikiwiki nei ka ʻoihana EV, a ʻaʻole maopopo i ka lanakila ʻana o nā cell prismatic a i ʻole cylindrical cell.I kēia manawa, ʻoi aku ka laulā o nā cell cylindrical i ka ʻoihana EV, akā aia nā kumu e noʻonoʻo ai e loaʻa nā cell prismatic i ka kaulana.

ʻO ka mea mua, hāʻawi nā cell prismatic i kahi manawa e hoʻohaʻahaʻa i nā kumukūʻai ma ka hoʻemi ʻana i ka helu o nā hana hana.ʻO kā lākou hōʻano e hiki ai ke hana i nā pūnaewele nui aʻe, e hōʻemi ana i ka helu o nā pili uila e pono e hoʻomaʻemaʻe a welded.

ʻO nā pākiki Prismatic nō hoʻi ke ʻano kūpono no ka kemika lithium-iron phosphate (LFP), kahi hui o nā mea i ʻoi aku ka liʻiliʻi a maʻalahi.ʻAʻole like me nā mea kemika ʻē aʻe, hoʻohana nā pākaukau LFP i nā kumuwaiwai ma nā wahi āpau o ka honua.ʻAʻole lākou makemake i nā mea laʻaʻole a me ka pipiʻi e like me ka nickel a me ka cobalt e hoʻonui i ke kumukūʻai o nā ʻano kelepona ʻē aʻe.

Aia nā hōʻailona ikaika e puka mai ana nā cell prismatic LFP.Ma Asia, ua hoʻohana mua nā mea hana EV i nā ʻona LiFePO4, kahi ʻano pākaukau LFP ma ke ʻano prismatic.Ua ʻōlelo pū ʻo Tesla ua hoʻomaka ʻo ia e hoʻohana i nā pihi prismatic i hana ʻia ma Kina no nā ʻano maʻamau o kāna mau kaʻa.

He mau mea koʻikoʻi ko ka LFP chemistry, akā naʻe.No ka mea hoʻokahi, ʻoi aku ka liʻiliʻi o ka ikehu ma mua o nā kemika ʻē aʻe e hoʻohana ʻia nei a, no laila, ʻaʻole hiki ke hoʻohana ʻia no nā kaʻa hana kiʻekiʻe e like me nā kaʻa uila Formula 1.Eia kekahi, paʻakikī nā ʻōnaehana hoʻokele pākaukau (BMS) i ka wānana ʻana i ke kiʻekiʻe o ke kau ʻana o ka pākaukau.

Hiki iā ʻoe ke nānā i kēia wikiō e aʻo hou e pili ana i kaLFPkemika a me ke kumu e kaulana ai.
