ʻO nā loina hana pākaukau sodium-ion a me nā pono a me nā hemahema

ʻO ka manaʻo o ka hana pākaukau sodium-ion

ʻO nā pākaʻi sodium-ion (SIBs no ka pōkole) he mau ʻona hoʻopaʻa ikehu hiki ke hoʻihoʻi ʻia i loaʻa nā pono o ka hiki ke kiʻekiʻe, ke kaumaha māmā, ka hana haʻahaʻa wela, ka haʻahaʻa haʻahaʻa, a me ke kumu kūʻai haʻahaʻa. Hiki i ka mea hana SIB i hoʻomohala ke hoʻololi i nā pākaukau lithium Graphene kuʻuna e hoʻoikaika ikaika i ka hoʻohana ʻana i ka ikehu kanaka.

ʻO ka mea maʻamau, ʻo ke kumu hana o SIBs penei: i ka wā e hoʻouka ai / hoʻokuʻu ʻana, piʻi a emi iho ka neʻe ʻana o Na + ma nā electrodes o SIBs, a me ka hoʻohana ʻana i nā ukana a me nā loli i kā lākou mau electrodes, ka hoʻopiʻi oxidation / hōʻemi hope loa e hoʻopuka i nā paʻa hydrogen. . Hoʻopau ʻia kēia mau hopena e nā pahu kūʻē ʻelua o ka cell electrochemical. Aia kekahi pahu kū'ē i ka Na+ electrolyte, a ʻo kekahi ipu ʻē aʻe he wai electrode.

I mea e hoʻokō ai i ka mana kiʻekiʻe o kēia manawa a me nā koi nui o nā huahana uila, makemake nā mea noiʻi e hoʻohana i nā electrodes curved e hōʻemi i ka nui o ka pākaukau o SIB. Ke hoʻohālikelike ʻia me nā ʻano pākaukau lithium-ion ʻē aʻe, hiki i nā electrodes curved ke hoʻololi i ka Na + ma waena o nā pahu ʻelua i ʻoi aku ka maikaʻi. Hiki ke hoʻomaikaʻi ʻia nā SIB i loko o nā electrodes nano-copolymer, e hōʻoiaʻiʻo ana i ka hana kiʻekiʻe a me ka hana mau o ka pākaukau i ka wā o nā kaʻina hana pololei.

20 ka pono a me ka pono ole

pono:

1. ʻOi aku ka nui o nā pāpaʻi sodium-ion a hiki ke mālama i ka ikehu hou aʻe, e ʻoi aku ka maikaʻi o nā noi nui;

2. ʻOi aku ka liʻiliʻi o nā SIB i ka nui a ʻoi aku ka maʻalahi o ke kaumaha, hiki ke mālama i ke ākea a me ke kaumaha;

3. Loaʻa i ka pale wela maikaʻi a me ke kūpaʻa wela kiʻekiʻe;

4. Li'ili'i iho-ho'oku'u 'ia 'ana, 'oi aku ka lō'ihi mālama ikehu;

5. ʻOi aku ka palekana o nā SIB ma mua o nā ʻokoʻa ʻē aʻe a ʻaʻole hiki ke ʻā i ka polarization wai;

6. Hiki ke ho'ohana hou 'ia i nā manawa he nui;

7. Loaʻa i nā SIB nā kumu kūʻai haʻahaʻa a mālama i nā kumukūʻai waiwai i ka hana.

hemahema:

1. He haʻahaʻa haʻahaʻa ko SIB ma lalo o nā kūlana maʻamau a ʻaʻole kūpono no ka hoʻohana ʻana i nā noi kiʻekiʻe;

2. Loaʻa i nā SIB nā conductivity kiʻekiʻe, e hopena i ka haʻahaʻa haʻahaʻa a me ka hoʻokuʻu ʻana;

3. He kiʻekiʻe ke kūʻē o loko, a ʻo ka hoʻouka ʻana a me ka hoʻokuʻu ʻana i nā kaʻina hana e hoʻopau nui ai;

4. ʻAʻole paʻa ka mea electrode a paʻakikī e mālama i ka manawa lōʻihi;

5. ʻOi aku ka nui o ka hāʻule ʻole ʻana o nā pākahi ma lalo o nā wela kiʻekiʻe a me nā kūlana koʻikoʻi;

6. ʻO ka emi ʻana o ka hiki o nā SIB e hoʻonui i nā poho i ka wā e kaa ana;

7. ʻAʻole hiki i nā huahana uila a pau ke hoʻohana i nā pāpaʻi sodium-ion. No ka laʻana, pono kekahi mau mea hana e mālama i kekahi volta komo ma mua o ka hiki ke hana pono.
