Guoxuan: Ua hōʻea mākou i ka 0,212 kWh / kg i kā mākou mau keena LFP, hele mākou i mua. ʻO kēia nā pūnaewele NCA / NCM!
Ua haʻaheo ka poʻe Kina Guoxuan i ko lākou komo ʻana i kahi ʻāpana i noho mua ʻia e nā cell lithium-ion wale nō me nā cathodes i loko o ka cobalt. Ua ʻōlelo ka hui ua hiki iā ia ke hoʻokō i ka ikaika o ka ikehu ma luna o 0,2 kWh / kg i kahi cell lithium iron phosphate (LFP) hou i loko o kahi sachet.
LFP pūnaewele - hoʻokahi lā "nawaliwali loa" lilo i "maikaʻi"
He nui nā pōmaikaʻi o nā cell lithium iron phosphate: ʻaʻole lākou e hoʻohana i ka cobalt, no laila ʻoi aku ka maikaʻi ma mua o nā pūnaewele me nā cathodes i loaʻa kēia mea. Eia kekahi, lākou emi loa ke ahi ke poino a ku paa mau kaukani o nā pōʻai hoʻoili... Loaʻa iā lākou hoʻokahi drawback nui: hāʻawi lākou i ka ikehu haʻahaʻa haʻahaʻa ma mua o nā pūnaewele NCA / NCM no ka mea aia lākou ma lalo o 0,2 kWh / kg, ʻoiai ʻo NCA / NCM ua ʻoi aku ma mua o 0,25 a ke kokoke nei i 0,3 kWh. / kg.
ʻO ka liʻiliʻi paha pēlā a hiki i kēia manawa.
ʻO ka hui Kina ʻo Guoxuan, ka mea e hoʻolako nei i nā pūnaewele LFP i ka mākeke Kina, e hōʻike ana ua kūleʻa ʻo ia i ka hana ʻana i nā cell lithium iron phosphate i loko o nā ʻeke (kiʻi) me ka ikaika o ka ikehu o 0,212 kWh/kg. ʻAʻole i pau, makemake ka ʻoihana e hōʻea i ka 2021 kWh/kg i 0,23 a hiki i 2022 kWh i 0,26, ʻo ia ka waiwai ma hope o nā cell NCA/NCM.
Haʻaheo ka mea hana i ka hoʻohana ʻana i ka ʻenehana jelly-roll-to-module, e like me ka inoa e ʻōlelo ai, hiki ka hoʻohana ʻana i nā pūʻulu o nā cell e like me nā modula, me ka ʻole o nā pā. Eia naʻe, ʻaʻole hōʻike ka kiʻi i ka loulou e hāʻawi i kahi manawa kūpono. Inā pēlā, pono e loaʻa iā ia kekahi ʻano "comb", he kiʻi metala i hoʻopili ʻia ma nā ʻaoʻao lōʻihi o ka ʻeke, ma ka liʻiliʻi loa mākou e manaʻo ai.
ʻAʻole ʻoe e ʻike i kekahi mea e like me kēia (kumu):
E hoihoi paha kēia iā ʻoe:
