Pili ʻia nā ʻōhua paʻa i ke anu?

ka hopena o ke anu i nā ʻōhua paʻaa he aha ka hana e pili ana ia mea:

No ke aha he pilikia ke anu

1. Haʻahaʻa ionic conductivity

   • ʻO nā electrolytes paʻa (ceramics, sulfides, polymers) ke hilinaʻi nei i nā ion lithium e lele ana ma o nā hale aniani a i ʻole polymer.

   • I nā haʻahaʻa haʻahaʻa, lohi kēia lele ʻana, no laila kapiʻi ka kūʻē o lokoa hāʻule ka hāʻawi mana.

2. Nā pilikia pilina

   • I loko o kahi pākaukau paʻa, he mea koʻikoʻi ka pilina ma waena o ka electrolyte paʻa a me nā electrodes.

   • Hiki i nā mahana anu ke ho'ēmi i nā mea i nā uku likeʻole, e hana anamicro-āwahama nā pilina → e hoʻomāinoino i ke kahe o ka ion.

3. Paʻakikī ka hoʻouka ʻana

   • E like me nā pākahi lithium-ion wai, e hoʻopaʻa ana i nā haʻahaʻa haʻahaʻa loahoʻopili lithium(Metalic lithium e hana ana ma ka anode).

   • Ma ka mokuʻāina paʻa, hiki i kēia ke ʻoi aku ka pōʻino no ka mea hiki i nā dendrites (nā waihona lithium e like me ke kui) ke haki i ka electrolyte paʻa.

Hoʻohālikelike ʻia me ka lithium-ion maʻamau

• Liquid electrolyte lithium-ion: ʻOi aku ka mānoanoa o ka wai (emi conductive), hōʻemi i ka laulā a me ka wikiwiki o ka hoʻouka ʻana.

• ʻO ka lithium-ion paʻa: ʻOi aku ka palekana i ke anu (ʻaʻohe wai maloʻo/leaking), akāe nalowale ana ka conductivityno ka mea, ʻaʻole lawe maikaʻi nā mea paʻa i nā ion i nā manawa haʻahaʻa.

Nā hāʻina o kēia manawa i ka noiʻi

1. Sulfide electrolytes

   • ʻO kekahi mau electrolytes paʻa paʻa sulfide e mālama i ka conductivity kiʻekiʻe ma lalo o 0 °C.

   • Ke hoʻohiki nei no nā EV ma nā wahi anu.

2. Polymer-ceramic hybrids

   • ʻO ka hui pū ʻana i nā polymers maʻalahi me nā ʻāpana seramika e hoʻomaikaʻi i ke kahe ʻana o ka ion ma nā haʻahaʻa haʻahaʻa me ka mālama ʻana i ka palekana.

3. ʻEnekinia Interface

   • Ke hoʻomohala ʻia nei nā uhi a i ʻole nā ​​papa hoʻopaʻa no ka mālama ʻana i ka pilina electrode-electrolyte i ka wā e loli ana ka wela.

4. Nā ʻōnaehana hoʻomehana mua i nā EV

   • E like me nā EV o kēia lā i hoʻomaʻamaʻa i nā ʻeke wai ma mua o ka hoʻopaʻa ʻana, hiki ke hoʻohana i nā EV solid-state e hiki mai ana.hooponopono welae hoʻopaʻa i nā cell i ko lākou laulā kūpono (15-35 °C).

Hōʻuluʻulu manaʻo:
Hoʻopilikia maoli ʻia nā ʻōhua paʻa i ke anuanu, ma muli o ka haʻahaʻa haʻahaʻa o ka ion conductivity a me ka pale ʻana o ka interface. ʻOi aku ka palekana ma mua o ka lithium-ion wai i kēlā mau kūlana, akāHiki ke hāʻule nui i lalo o ka 0 °C ka hana (ka palena, ka uku uku, ka mana puka).. Ke hana ikaika nei nā mea noiʻi i nā electrolytes a me nā hoʻolālā e noho conductive i ke anuanu, e manaʻo ana no ka hoʻohana pono ʻana i nā EV a hiki i ka hoʻoilo.
