He aha nā ʻōhua paʻa i hana ʻia?

Ua like ka manaʻo o nā ʻōhua paʻa i ka lithium-ion, akā ma kahi o ka hoʻohana ʻana i ka wai electrolyte, hoʻohana lākou i kahipaʻa electrolyte. ʻO kā lākou mau mea nui:

1. Cathode (Positive Electrode)

• Hoʻokumu pinepine ma luna opūhui lithium, e like me nā pākahi lithium-ion o kēia lā.

• Nā laʻana:

  • Lithium cobalt oxide (LiCoO₂)

  • Lithium iron phosphate (LiFePO₄)

  • Lithium nickel manganese cobalt oxide (NMC)

• Ke ʻimi nei kekahi mau hoʻolālā paʻa i nā cathodes kiʻekiʻe-volt a i ʻole sulfur.

2. Anode (Negative Electrode)

• Hiki ke hoʻohanametala lithium, ka mea iʻoi aku ka nui o ka ikehu ma mua o graphite anodes i maʻamau Li-ion pākahi.

• Nā mea hiki ʻē aʻe:

  • graphite(e like me nā pākahi o kēia manawa)

  • Silikanā mea hoʻohuihui

  • Lithium titanate (LTO)no nā noi hoʻouka wikiwiki

3. Electrolyte paʻa

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

• Keramika(hoʻokumu ʻia ka oxide, hoʻokumu i ka sulfide, ʻano garnet, ʻano perovskite)

• Polymers(nā polymers paʻa me nā paʻakai lithium)

• ʻO nā electrolytes hui(ka hui pū ʻana o nā seramika a me nā polymers)

4. Mea hoʻokaʻawale

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

I ka pōkole:Hana ʻia nā ʻōhua paʻa me ka ametala lithium a i ʻole graphite anode, alithium-based cathode, a he apaʻa electrolyte(Karamika, polymer, a i ʻole ka hui ʻana).
