He aha nā mea i hana ʻia ai nā pila paʻa?

Ua like ke ʻano o nā pila paʻa-kūlana me nā pila lithium-ion, akā ma kahi o ka hoʻohana ʻana i kahi electrolyte wai, hoʻohana lākou i kahielectrolyte paʻaʻO kā lākou mau ʻāpana nui:

1. Cathode (ʻElekode Maikaʻi)

• Hoʻokumu pinepine ʻia ma luna onā hui lithium, ua like me nā pila lithium-ion o kēia wā.

• Nā Laʻana:

  • Lithium cobalt oxide (LiCoO₂)

  • Lithium hao phosphate (LiFePO₄)

  • Lithium nickel manganese cobalt oxide (NMC)

• Ke nānā pū nei kekahi mau hoʻolālā paʻa-mokuʻāina i nā cathodes kiʻekiʻe-voltage a i ʻole sulfur.

2. Anode (ʻElekoda Maikaʻi ʻole)

• Hiki ke hoʻohanametala litiuma, nona ka nui o ka ikehu kiʻekiʻe ma mua o nā anodes graphite i loko o nā pila Li-ion maʻamau.

• Nā mea hiki ʻē aʻe:

  • Graphite(e like me nā pila o kēia manawa)

  • Silikanā mea i hoʻohuihui ʻia

  • ʻO ka litiuma titanate (LTO)no nā noi hoʻouka wikiwiki

3. ʻElektrolite paʻa

ʻO kēia ka ʻokoʻa nui. Ma kahi o ka wai, he paʻa ka mea lawe ion. ʻO nā ʻano nui:

• Nā keramika(mea i hana ʻia me ka oxide, mea i hana ʻia me ka sulfide, ʻano garnet, ʻano perovskite)

• Nā Polymers(nā polymers paʻa me nā paʻakai lithium)

• Nā electrolytes hui pū ʻia(ka hui pū ʻana o nā keramika a me nā polymers)

4. Mea hoʻokaʻawale

• I loko o nā hoʻolālā mokuʻāina paʻa he nui, hana pū ka electrolyte paʻa ma ke ʻano he mea hoʻokaʻawale, e pale ana i nā kaapuni pōkole ma waena o ka anode a me ka cathode.

I ka pōkole:ʻO ka maʻamau, hana ʻia nā pila paʻa-kūlana me kahianode metala lithium a i ʻole graphite, hecathode i hoʻokumu ʻia i ka lithium, a me kahielectrolyte paʻa(ceramic, polymer, a i ʻole composite).
