I loko o ka honua e ulu wikiwiki nei o ka mālama ʻana i ka ikehu, ʻelua mau ʻano pākaukau i hana i nā poʻomanaʻo:ʻO nā ʻanuʻu sodium-ion (SIB)aʻO nā ʻokoʻa lithium-iron-phosphate (nā ʻeke LFP). ʻO ka ʻenehana pākahi sodium a me ka ʻenehana pākahi lithium he mau ʻenehana hoʻohiki, akā loaʻa iā lākou nā hiʻohiʻona ʻokoʻa e kūpono ai no nā noi like ʻole. Ma kēia ʻatikala, e ʻimi mākou i ke ʻano o ka sodium-ion a me ka lithium-iron-phosphate, a laila hoʻohālikelike i kā lākou ʻokoʻa ma muli o nā ʻike noiʻi hou.
He aha nā Bateri Sodium-ion (SIBs)?
ʻO nā ʻanuʻu sodium-ion (SIB)He ʻano o ka pākaukau e hoʻihoʻi hou ʻia e hoʻohana ana i nā ion sodium (Na+) ma ke ʻano he mea lawe uku. He nui a he mea kūʻai ʻole ka Sodium, e hana ana i nā SIB i ʻenehana pākaukau hou e pani ai i ka lithium.
Hoʻohana maʻamau nā SIB i ke kalapona paʻakikī e like me ka mea anode, ʻokoʻa ia mai ka graphite i hoʻohana mau ʻia i nā LIB. Hiki ke ʻokoʻa nā mea cathode, akā ua hoʻolālā pinepine ʻia lākou e hoʻokipa i ka nui o nā ion sodium i hoʻohālikelike ʻia me nā ion lithium.
He aha nā Bateri LFP (Lithium-iron-phosphate Battery)?
ʻO nā ʻokoʻa lithium-iron-phosphate (nā ʻeke LFP)He ʻano subtype o ka waihona pākaukau lithium-ion e hoʻohana ana i ka lithium iron phosphate (LiFePO4) ma ke ʻano he cathode.
Ua ʻike ʻia nā pākahi Lithium LiFePO4 no ko lākou kūpaʻa wela, ke ola pōʻai lōʻihi, a me ka palekana.
Hoʻohana nui ʻia lākou i nā kaʻa uila (EVs), ka mālama ʻana i ka ikehu hou, a me nā noi ʻē aʻe kahi koʻikoʻi ka palekana a me ka lōʻihi.

| Nā Koina Hoʻohālikelike | Pākuʻi Sodium-ion | ʻO ka Battery Lithium-iron-phosphate |
| Hana Uila | - ʻOi aku ka maʻalahi i ka state of charge (SOC) a me ka mahana. - Hoʻonui nui ʻia ka pale ʻana o ka puʻuwai a me ka impedance ma SOC haʻahaʻa (<30%) akā hoʻemi i ka SOC kiʻekiʻe. | - Ke hilinaʻi liʻiliʻi i ka SOC a me ka mahana. - Paʻa kūpaʻa a me ka impedance ma waena o SOC a me ka mahana. |
| Mea Anode | Hoʻohana i ke kalapona paʻakikī e like me ka anode mea, kūpono no ka sodium ion intercalation a me ka deintercalation. | Hoʻohana i ka graphite e like me ka anode mea, kūpono no ka lithium ion intercalation a me ka deintercalation. |
| ʻO ka maikaʻi a me ka lilo o ka ikehu | - ʻO ka pono e hilinaʻi nui ʻia ma SOC. - Ua emi loa ka lilo o ka ikehu i ka wā e holo kaʻa ai ma waena o 50%-100% SOC. | - ʻAʻole i hilinaʻi ka maikaʻi ma luna o SOC. - Mālama i ka hana kūpono ma waena o kahi ākea o SOC. |
| Ke Kumukuai a me ka Mea Nui | - He nui a haʻahaʻa ke kumu kūʻai o ka sodium, e hāʻawi ana i nā pono kumu kūʻai. - Ke ulu nei ka ʻenehana a me nā kaʻina hana hana, hiki ke hoʻopau i nā pōmaikaʻi kumukūʻai no ka wā pōkole. | - He liʻiliʻi a ʻoi aku ka pipiʻi o ka lithium. - ʻO nā kaʻina hana hana makua a hoʻokumu ʻia ke kaulahao lako e hoʻokūkū i ke kumukūʻai i ka wā pōkole. |
| Nā noi | - He kūpono no nā noi pili kālā, e like me ka mālama ʻana i ka ikehu grid. - He kūpono no nā noi kahi i emi ai ke kaumaha a me ka nui. | - He kūpono no nā noi e koi ana i ka palekana kiʻekiʻe a me ke kūpaʻa, e like me nā kaʻa uila a me ka mālama ʻana i ka ikehu lā. - Kūpono no nā hiʻohiʻona e koi ana i ke ola pōʻai lōʻihi a me ka hilinaʻi kiʻekiʻe. |
| Hoʻonaʻauao wela | - Ua loli hou ka hana ma lalo o nā mahana haʻahaʻa a kiʻekiʻe paha. - Hoʻololi koʻikoʻi ka hoʻololi ʻana o ka mahana i ka pale a me ka impedance. | - Hana kūpaʻa ma waena o kahi ākea ākea. - He liʻiliʻi ka hopena o nā hoʻololi wela i ka hana. |

| Palekana | - Ka palekana maikaʻi, akā hiki i ka anode kalapona paʻakikī ke kumu i ka hysteresis. | - Palekana maikaʻi, kūpaʻa wela kiʻekiʻe, a me ka haʻahaʻa haʻahaʻa o ka holo ʻana i ka wela. |
| Ka noiʻi a me ka hoʻomohala ʻana | - Ke hoʻomohala nei ka ʻenehana, me ka noiʻi ʻana i ka hoʻonui ʻana i nā mea anode a me nā cathode e hoʻomaikaʻi ai i ka hana. | - ʻenehana makua, me ka noiʻi ʻana i ka hoʻomaikaʻi hou ʻana i ka ikehu a me ka hōʻemi ʻana i nā kumukūʻai. |
Hōʻuluʻulu manaʻo:
- ⭐ʻO nā ʻanuʻu sodium-ion (SIB) hāʻawi i nā mea maikaʻi i ke kumukūʻai a me ka nui o nā mea, akā ʻoi aku ka maʻalahi i ka mahana a me ka SOC, e hoʻolilo iā lākou i kūpono no nā noi koʻikoʻi me ka liʻiliʻi o nā koi hana.
- ⭐ʻO LiFePO4 Nā Bateri Lā ʻoi aku ka maikaʻi i ka paʻa, palekana, a me ka maikaʻi, e hoʻolilo iā lākou i mea kūpono no nā noi e koi ana i ka hana kiʻekiʻe, palekana, a me ke ola lōʻihi.
Hāʻawi kēia papa ʻaina i ka hoʻohālikelike ʻike a me ka intuitive o nā ʻenehana pākahi ʻelua, e kōkua ana i nā mea hoʻoholo e koho i ke koho kūpono loa e pili ana i nā pono kikoʻī.
Ka hopena
ʻO ka Sodium-ion a me kaʻo nā ʻanuʻu lithium ion phosphateLoaʻa iā lākou nā pōmaikaʻi a me nā pilikia. Hāʻawi nā pāʻani sodium i ka hiki ke uku haʻahaʻa ma muli o ka nui o ka sodium, akā ʻoi aku ka maʻalahi o nā loli i ka SOC a me ka mahana, hiki ke hoʻopilikia i ko lākou pono. Ma ka lima ʻē aʻe,LiFePO4 mau pākahi lithiumhāʻawi i ka hana paʻa, ke ola pōʻai lōʻihi, a me ka palekana kiʻekiʻe, e hoʻolilo iā lākou i mea kūpono no nā ʻano noi he nui, ʻoi aku ka nui o ka hilinaʻi.
Ke hoʻomau nei ka noiʻi, hiki iā mākou ke manaʻo i nā holomua hou aʻe i nā ʻenehana ʻelua, hiki ke alakaʻi i nā noi hou a me ka hoʻomaikaʻi ʻana i ka hana. I kēia manawa, ke koho ma waena o Sodium-ion a meʻo nā ʻanuʻu lithium phosphatee hilinaʻi ʻia i nā koi kikoʻī o ka noi, me ka uku, ka hana, a me nā noʻonoʻo palekana.
Ma ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o kēia mau ʻano ʻokoʻa ʻelua, hiki i nā ʻoihana ke hoʻoholo i ka ʻike e pili ana i ka ʻenehana i kūpono i ko lākou pono, inā paha e hana ana lākou i nā pihi no nā kaʻa uila, ka mālama ʻana i ka ikehu hou, a i ʻole nā noi ʻē aʻe.
