E kūʻē i ke kua o ka hoʻololi ʻana i ka ikehu honua a me nā pahuhopu "ʻelua-carbon", ʻenehana ʻenehana, ma ke ʻano he kumu nui o ka mālama ʻana i ka ikehu. I kēia mau makahiki i hala iho nei, ua puka mai nā pāpaʻi sodium-ion (SIBs) mai nā laboratories a hiki i ka ʻenehana, e lilo ana i mea hoʻonā manaʻo e mālama nui ʻia ma hope o nā pā lithium-ion.
ʻIkepili kumu e pili ana i nā Bateri Sodium-ion
ʻO nā pāpaʻi sodium-ion kahi ʻano o ka pākaukau lua (rechargeable) e hoʻohana ana i nā ion sodium (Na⁺) ma ke ʻano he mea lawe uku. ʻO kā lākou kumu hana e like me nā pā lithium-ion: i ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana, hoʻokuʻu ʻia nā ion sodium ma waena o ka cathode a me ka anode ma o ka electrolyte, hiki ke mālama i ka ikehu a hoʻokuʻu.
·Na Mea Koko: Hoʻohana maʻamau ka cathode i nā ʻokikene papa, nā pūhui polyanionic, a i ʻole nā analog polū Prussian; ʻO ka anode ka nui o ke kalapona paʻakikī a i ʻole ke kalapona palupalu; ʻO ka electrolyte he wai paʻakai sodium.
·ʻIke ʻenehana: Ua hoʻomaka ka noiʻi ʻana i nā makahiki 1980, a ua hoʻomaikaʻi maikaʻi ka holomua ʻana o nā mea hana a me nā kaʻina hana i ka nui o ka ikehu a me ke ola pōʻai, e hiki ai i ke kālepa ke hiki.
ʻO nā Bateri Sodium-ion vs. Nā Bateri Lithium-ion: Nā ʻokoʻa nui a me nā pono.
ʻOiai ke kaʻana like ʻana o nā pākahi sodium-ion me nā pā lithium-ion, ʻokoʻa loa lākou i nā waiwai waiwai a me nā hiʻohiʻona noi.
| Ana Hoʻohālikelike | ʻO nā Bateri Sodium-ion | Nā Bati Lithium-ion |
| Punawai Nui | Nui ka Sodium (2.75% i ka ʻōpala o ka Honua) a laha nui | ʻAʻole liʻiliʻi ka lithium (0.0065%) a paʻa i ka ʻāina |
| Koina | Hoʻohaʻahaʻa i nā kumukūʻai maka, ʻoi aku ka paʻa o ke kaulahao lako | ʻO ka volatility kumu kūʻai kiʻekiʻe no ka lithium, cobalt, a me nā mea ʻē aʻe, hilinaʻi i ka lawe ʻana mai |
| ʻAiʻi ikaika | Haʻahaʻa (120-160 Wh/kg) | ʻOi aku (200-300 Wh/kg) |
| Hana Haʻahaʻa-Mahana | Ka paʻa paʻa ʻana > 80% ma -20 ℃ | Hana maikaʻi ʻole i nā mahana haʻahaʻa, hiki ke hoʻohaʻahaʻa maʻalahi |
| Palekana | ʻO ke kūpaʻa wela kiʻekiʻe, ʻoi aku ka pale ʻana i ka overcharge/discharge | Pono ka hoʻokele koʻikoʻi i nā pilikia holo wela |
Nā Pōmaikaʻi Nui o nā Bateri Sodium-ion:
1.Kumukuai Haʻahaʻa a me ka hoʻomau waiwai: Loaʻa ka sodium i loko o ka wai kai a me nā minela, e hōʻemi ana i ka hilinaʻi ʻana i nā metala liʻiliʻi a me ka hoʻohaʻahaʻa ʻana i nā kumukūʻai lōʻihi e 30% -40%.
2. Palekana kiʻekiʻe a me ke kaiapuni: Kūʻokoʻa mai ka haumia metala kaumaha, kūpono me nā ʻōnaehana electrolyte palekana, a kūpono no ka mālama ʻana i ka ikehu nui.
3. Hiki ke hoʻololi i ke ana wela ākea: Hana maikaʻi loa i nā kaiapuni haʻahaʻa haʻahaʻa, kūpono no nā wahi anu a i ʻole nā ʻōnaehana mālama ikehu waho.
Nā Manaʻo Hoʻohana no nā Bateri Sodium-ion
Me ka holomua ʻenehana, hōʻike ʻia nā pāpaʻi sodium-ion i ka mana nui ma nā wahi aʻe:
1. Nā Pūnaehana Hoʻopaʻa Manaʻo Nui (ESS):
Ma ke ʻano he hopena hoʻohui no ka makani a me ka ikehu lā, hiki ke hoʻemi maikaʻi ʻia nā kumu kūʻai haʻahaʻa a me ka lōʻihi o ke ola ʻana o nā pāka sodium-ion i ke kumu kūʻai o ka uila (LCOE) a kākoʻo i ka shaving peak grid.
2. Nā Kaʻa Uila Haʻahaʻa a me nā Huila ʻElua:
Ma nā hiʻohiʻona me nā koi haʻahaʻa haʻahaʻa haʻahaʻa (e laʻa, nā kaʻa uila, nā kaʻa logistic), hiki i nā ʻeke sodium-ion ke pani i nā ʻakika lead-acid, e hāʻawi ana i nā pono kaiapuni a me ka waiwai.
3. Mana hoʻihoʻi a me ke kahua kahua waihona ikehu:
ʻO kā lākou hana ākea ākea e kūpono iā lākou no ka pono o ka mana hoʻihoʻi i nā noi e pili ana i ka wela e like me nā kahua kahua kamaʻilio a me nā kikowaena data.
Nā ʻano hoʻomohala e hiki mai ana
Wahi a nā wānana ʻoihana e ʻoi aku ka mākeke pākēneka sodium-ion honua ma mua o $ 5 biliona e 2025 a hiki i ka 10% -15% o ka mākeke pākahi lithium-ion ma 2030. ʻO nā kuhikuhi hoʻomohala e hiki mai ana:
·Mea Hana Hou: Ka hoʻomohala ʻana i nā cathodes mana kiʻekiʻe (e laʻa, nā ʻokikene papa ʻano O3) a me nā mea anode lōʻihi e hoʻonui ai i ka ikehu ma luna o 200 Wh/kg.
·Kaʻina Hana: Ka hoʻohana ʻana i nā laina hana pākaukau lithium-ion makua e hoʻonui i ka hana pākaukau sodium-ion a hoʻemi hou i nā kumukūʻai.
·Hoonui Noi: Hoʻopiha ʻana i nā pākahi lithium-ion no ke kūkulu ʻana i kahi kōpili ʻenehana mālama ikehu like ʻole.
Ka hopena
ʻAʻole i manaʻo ʻia ka piʻi ʻana o nā pākahi sodium-ion e pani i nā pā lithium-ion akā e hāʻawi i kahi koho ʻoi aku ka maikaʻi a palekana no ka mālama ʻana i ka ikehu. I loko o ka pōʻaiapili o ke kalapona neutrality, ʻo ko lākou ʻano waiwai a me ka hoʻohana ʻana e hoʻopaʻa i ko lākou wahi i ka ʻāina mālama mālama. Ma ke ʻano he paionia i ka ʻenehana ʻenehana ikehu,DALYe hoʻomau i ka nānā ʻana i ka hoʻomohala ʻana o ka ʻenehana ʻenehana sodium-ion, i hoʻopaʻa ʻia i ka hāʻawi ʻana i nā hopena ikehu kūpono a hoʻomau i kā mākou mea kūʻai.
E hahai mai iā mākou no nā ʻenehana hou aʻe!
