Ua hoʻopilikia ʻia anei nā pila paʻa e ke anu?

pehea ka hopena o ke anu i nā pila paʻaa me nā mea e hana ʻia nei e pili ana i ia mea:

No ke aha he paʻakikī ke anu

1. Ka hoʻokele ionic haʻahaʻa

   • Hilinaʻi nā electrolytes paʻa (ceramics, sulfides, polymers) i nā ions lithium e lele ana ma o nā ʻano kristal paʻa a i ʻole nā ​​​​​​ʻano polymer.

   • I nā mahana haʻahaʻa, lohi kēia lele ʻana, no lailapiʻi ka pale kūlokoa me nā emi ʻana o ka hāʻawi ʻana i ka mana.

2. Nā pilikia o ka pilina

   • I loko o kahi pākahiko paʻa, he mea koʻikoʻi ka hoʻopili ʻana ma waena o ka electrolyte paʻa a me nā electrodes.

   • Hiki i nā mahana anuanu ke hoʻemi i nā mea ma nā ʻano like ʻole, e hana ananā hakahaka liʻiliʻima nā interfaces → e hoʻonui ana i ke kahe ʻana o ka ion.

3. Ka paʻakikī o ka hoʻouka ʻana

   • E like me nā pila lithium-ion wai, ʻo ka hoʻouka ʻana ma nā mahana haʻahaʻa loa he pilikia iaka uhi ʻana i ka lithium(ka lithium metala e hana ana ma ka anode).

   • I ke kūlana paʻa, hiki i kēia ke ʻoi aku ka hōʻino ʻana no ka mea hiki i nā dendrites (nā waihona lithium e like me ke nila) ke wāwahi i ka electrolyte paʻa.

Hoʻohālikelike ʻia me ka lithium-ion maʻamau

• Lithium-ion electrolyte waiʻO ke anu e hoʻomānoanoa ai i ka wai (emi ka conductivity), e hōʻemi ana i ka laulā a me ka wikiwiki o ka hoʻouka ʻana.

• ʻIona lithium-kūlana paʻaʻOi aku ka palekana i ke anu (ʻaʻohe wai e hau/kahe ana), akānalowale nō ka conductivityno ka mea, ʻaʻole lawe maikaʻi nā mea paʻa i nā ion i nā mahana haʻahaʻa.

Nā hoʻonā o kēia manawa ma ka noiʻi

1. Nā electrolytes sulfide

   • Mālama kekahi mau electrolytes paʻa i hoʻokumu ʻia i ka sulfide i ka conductivity kiʻekiʻe ma lalo o 0 °C.

   • He ʻōlelo hoʻohiki no nā EV ma nā wahi anu.

2. Nā hui polymer-ceramic

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

3. ʻEnekinia pilina

   • Ke hoʻomohala ʻia nei nā uhi ʻana a i ʻole nā ​​​​papa buffer e mālama i ka paʻa o ka pilina electrode-electrolyte i ka wā o nā loli o ka mahana.

4. Nā ʻōnaehana hoʻomehana mua i nā EV

   • E like me nā EV o kēia lā e hoʻomehana ai i nā pila wai ma mua o ka hoʻouka ʻana, hoʻohana paha nā EV solid-state e hiki mai anaka hoʻokele welae mālama i nā pūnaewele i ko lākou pae kūpono (15–35 °C).

Hōʻuluʻulu manaʻo:
Hoʻopilikia maoli ʻia nā pila paʻa-kūlana e ke anu, ʻo ia hoʻi ma muli o ka haʻahaʻa o ka conductivity ion a me ke kū'ē ʻana o ka interface. ʻOi aku ka palekana o lākou ma mua o ka lithium-ion wai i kēlā mau kūlana, akāhiki i ka hana (ka laulā, ka helu hoʻouku, ka mana hoʻopuka) ke hāʻule nui ma lalo o 0 °CKe hana ikaika nei nā kānaka noiʻi i nā electrolytes a me nā hoʻolālā e noho conductive i ke anu, me ka manaʻo e hoʻohana pono ʻia i nā EV a hiki i nā aniau hoʻoilo.
