LiFePO4 vs. NMC: ʻO wai ka pila ʻoi aku ka maikaʻi no kāu ʻōnaehana lā home?

ʻAʻole ke koho ʻana i kahi pila solar e pili ana i ka hiki—e pili ana i ke koho ʻanaka ʻākau kemika no kou home ka wā e hiki mai ana. E wāwahi kākou i nā alakaʻi ʻoihana ʻelua.

ʻAʻole wale ka neʻe honua i ka ikehu hou he ʻano maʻamau; he hoʻololi koʻikoʻi ia i ke ʻano o ko kākou hoʻoikaika ʻana i ko kākou ola. No nā mea nona ka home, ʻo ke kikowaena o kēia kipi ka ʻōnaehana mālama ikehu. ʻOiai ʻo nā panela solar e hopu i ka ikehu, ʻo ka pila ke kumu o ka maikaʻi o kāu hoʻohana ʻana. I kēia manawa, ua noho aliʻi ʻia ka mākeke noho e ʻelua mau ʻano lithium-ion:Lithium Iron Phosphate (LiFePO4)a meʻOihana Manganese Nickelbalt (NMC).

Lawe mai kēlā me kēia ʻenehana i kahi ʻano kūikawā i ka papaʻaina. ʻO ke koho ʻana ma waena o lākou e pono ai ke kaulike o ka palekana, ka lōʻihi o ka manawa, ka hana, a me nā loina kaiapuni. Ma kēia alakaʻi, e wehe mākou i nā papa o kēia mau kemika ʻelua e kōkua iā ʻoe e hoʻoholo i kahi hoʻoholo naʻauao no kou home maʻŌnaehana WeSolar.

1. ʻO ka ʻEpekema: He aha ia Ma lalo o ke ʻO Hood?

I ka nānā mua ʻana, he mau pila "lithium" ʻelua, akā ʻo ko lāua ʻano i loko ke kumu o kā lāua hana.

Hoʻohana ʻo LiFePO4 i ka hao a me ka phosphate no ka cathode. Nui kēia mau mea a

paʻa kemika. ʻO NMC, ma ke ʻano ʻē aʻe, hoʻohana i ka hui ʻana o Nickel, Manganese, a me Cobalt. ʻO kēia

ʻAe ka hui ʻana i kahi nui o ka ikehu—ʻo ia hoʻi, hiki iā ʻoe ke hoʻopaʻa i ka mana hou aʻe i loko o kahi pahu liʻiliʻi a māmā.

2. Palekana ʻO ka mua: Ka Pōmaikaʻi o ke Kūlana Paʻa Thermal

ʻO ka palekana ka nīnau pinepine loa a mākou e loaʻa ai mai nā mea kūʻai aku ma waho. Ke hoʻokomo ʻoe i kahi pila i loko o kahi hale kaʻa a i ʻole ka lumi pono hana, makemake ʻoe i ka maluhia piha o ka noʻonoʻo.

LiFePO4ua manaʻo nui ʻia ʻo ia ka kemika lithium palekana loa i loaʻa i kēia lā. Loaʻa iā ia kahi paepae holo wela kiʻekiʻe, ʻo ia hoʻi hiki iā ia ke kū i nā mahana kiʻekiʻe ma mua o ka loaʻa ʻana o ka pilikia o ke ahi a i ʻole ka hāʻule ʻana. No ka mea, ua paʻa pono ka oxygen i loko o ka molekole phosphate

i hoʻopaʻa ʻia, ʻaʻole ia e hoʻokuʻu i ka oxygen i ka wā o kahi kaapuni pōkole, e pale ana i ka "holo wela" hiki ke hana i nā pila ʻē aʻe.

NMCHe kūpono loa nā pila akā he haʻahaʻa ka mahana wela. ʻOiai ke hele mai nei nā ʻōnaehana NMC hou me nā ʻōnaehana hoʻoluʻu a me ka hoʻokele akamai, ʻoi aku ko lākou ʻano maʻalahi i ka wela a me ka pōʻino kino ma mua o ko lākou mau hoa LFP.

3. Ke ola: ʻO wai ka mea e hele ai Ka mamao?

He hoʻopukapuka kālā nui ka pākahiko solar, a ʻo "Cycle Life" ke ana e hoʻoholo ai i kāu hoʻihoʻi kālā (ROI). Hoʻokahi pōʻaiapuni e like me ka hoʻopiha piha ʻana a me ka hoʻokuʻu ʻana.

•LiFePO4:ʻO kēia mau pila ka mea holo marathon o ka honua mālama. Hāʻawi pinepine lākou i 4,000 a 8,000+ mau pōʻaiapuni. No ka hapa nui o nā ʻohana, ʻo ia hoʻi he 10 a 15 mau makahiki o ka lawelawe hilinaʻi ma mua o ka ʻike ʻana i ka pohō nui o ka mana.

•NMC:Ua like kēia me nā sprinter. Hāʻawi lākou i ka hana kiʻekiʻe akā ma ke ʻano laulā he pōkole ko lākou ola o 1,000 a 2,500 mau pōʻaiapuni. Ma hope o 8 mau makahiki, hoʻomaka ka nui o nā pila NMC e hōʻike i ka emi ʻana o ko lākou hiki ke hoʻopaʻa i kahi hoʻopiʻi.

5. Kaiapuni Nā Kūlana a me ke Kūlana Paʻa

ʻO ke kūpaʻa ke kumu o kā mākou hana maʻŌnaehana WeSolarʻO ka cobalt i hoʻohana ʻia ma NMC

ua hoʻāla nā pila i nā hopohopo koʻikoʻi e pili ana i nā hana mining a me nā pono kanaka ma kekahi mau wahi. Eia kekahi, he metala kaumaha ka cobalt e hoʻolilo ai i ka hana hou ʻana i mea paʻakikī.
