No ke aha i ʻoi aku ka maikaʻi o nā pāpaʻi sodium-ion?

Noʻonoʻo ʻia nā pākaona sodium-ionʻoi aku ka maikaʻi ma mua o nā pākahi lithium-ion ma nā ʻano kikoʻī, ʻoi aku no nā noi nui a me nā kumu kūʻai. Eiano ke aha e ʻoi aku ai ka maikaʻi o nā pākahi sodium-ion, ma muli o ka hihia hoʻohana:

1. Nui a me ke kumu kūʻai haʻahaʻa

• Sodiumʻo ia ka 6 o ka mea nui loa ma ka Honua (mai ka paʻakai).

• ʻO iamakamaealoaʻa ākeapuni honua.

• Lithium, cobalt, a me ka nickel i hoʻohana ʻia i nā pākahi Li-ionʻoi aku ka liʻiliʻi a ʻoi aku ka pipiʻi, me nā manaʻo geopolitical a me ke kaiapuni e pili ana i kā lākou mining.

2. Ka hopena o ke kaiapuni haahaa

• ʻO nā ʻanuʻu sodium-ionʻaʻole makemake i ka cobalt a i ʻole nickel, pale aku i nā hana eli pono ʻole a me ka hōʻemi ʻana i ka pōʻino o ke kaiapuni.

• ʻOi aku ka maʻalahi o ka hana hou ʻana a me ka liʻiliʻi o ka ʻōpala pōʻino.

3. Hoʻonui i ka palekana

• ʻO ka pilikia haʻahaʻa o ka mahuka wela(ahi a pahū paha).

• Hiki ke hoʻohananā mea ʻohi aluminima nā electrodes ʻelua, kahi e hoʻomaikaʻi ai i ke kūpaʻa a hoʻemi hou i ke kumukūʻai.

4. ʻOi aku ka maikaʻi o ka hana haʻahaʻa haʻahaʻa

• Hiki ke hana maikaʻi nā ʻōhua Na-ion ma–20°C a i ole ke anu, ʻo ia ka palena no nā kemika Li-ion he nui.

5. He kūpono no ka mālama ʻana i ka nui

• Kūpono nowaihona ikehu pahu, mahiʻai lā a me ka makani, a me nā ʻōnaehana hoʻihoʻi.

• ʻAʻole koʻikoʻi ka nui o ka ikehu i kēia mau noi, e hana ana i ka sodiumʻoi aku ka waiwai o ke kumukūʻai a me ka palekana.

6. Hiki ke hoʻouka wikiwiki (Hoʻomaikaʻi)

• Hiki i kekahi mau mea kemika sodium-ion hounā pōʻai wikiwiki / hoʻokuʻu, maikaʻi ia no ka mālama ʻana i ka ikehu a me kekahi mau hoʻohana kaʻa.

Aia lākou i heaʻAʻoleʻOi aku ka maikaʻi

• Haʻahaʻa ikehu haʻahaʻa(100–160 Wh/kg vs. Li-ion's 150–250+ Wh/kg).

• ʻOi aku ke kaumaha a me ka nuino ka nui like o ka ikehu.

• Loaʻa ka loaʻa kālā- aia nō i ka wā mua o ka hana nui.
