Aia nā pila Lithium-ion i loko o aneane nā hāmeʻa āpau āu e loaʻa ai. Mai nā kelepona akamai a i nā kaʻa uila, ua hoʻololi kēia mau pila i ke ao nei. Eia nō naʻe, he nui nā hemahema o nā pila lithium-ion e hoʻolilo ai i ka lithium iron phosphate (LiFePO4) i koho maikaʻi aʻe.

Pehea ka ʻokoʻa o nā pila LiFePO4?

ʻO ka ʻōlelo pololei, he mau pila lithium-ion nō hoʻi nā pila LiFePO4. Nui nā ʻano like ʻole o ke kemika o nā pila lithium, a hoʻohana nā pila LiFePO4 i ka lithium hao phosphate ma ke ʻano he mea cathode (ka ʻaoʻao maikaʻi ʻole) a me kahi electrode kalapona graphite ma ke ʻano he anode (ka ʻaoʻao maikaʻi).

ʻO nā pila LiFePO4 ka haʻahaʻa loa o ka nui o ka ikehu o nā ʻano pila lithium-ion o kēia manawa, no laila ʻaʻole makemake ʻia no nā mea hana i kaupalena ʻia e ka wahi e like me nā kelepona akamai. Eia nō naʻe, hele mai kēia pānaʻi nui o ka ikehu me kekahi mau pono maikaʻi.

Nā Pōmaikaʻi o nā Pila LiFePO4

ʻO kekahi o nā hemahema nui o nā pila lithium-ion maʻamau, ʻo ia ka hoʻomaka ʻana o lākou e pau ma hope o kekahi mau haneli mau pōʻaiapuni hoʻouka. ʻO ia ke kumu e nalowale ai kāu kelepona i kona mana kiʻekiʻe loa ma hope o ʻelua a ʻekolu paha mau makahiki.

ʻO ka maʻamau, hāʻawi nā pila LiFePO4 ma ka liʻiliʻi he 3000 mau pōʻaiapuni hoʻopiha piha ma mua o ko lākou hoʻomaka ʻana e nalowale ka mana. ʻOi aku ka maikaʻi o nā pila e holo ana ma lalo o nā kūlana kūpono ma mua o 10,000 mau pōʻaiapuni. ʻOi aku ka makepono o kēia mau pila ma mua o nā pila lithium-ion polymer, e like me nā mea i loaʻa i nā kelepona a me nā kamepiula lawe lima.

Ke hoʻohālikelike ʻia me kahi ʻano maʻamau o ka pākahiko lithium, ʻo ka nickel manganese cobalt (NMC) lithium, he haʻahaʻa iki ke kumukūʻai o nā pākahiko LiFePO4. I hui pū ʻia me ke ola i hoʻohui ʻia o LiFePO4, ʻoi aku ka liʻiliʻi o ke kumukūʻai ma mua o nā koho ʻē aʻe.

Eia kekahi, ʻaʻohe nickel a cobalt paha i loko o nā pila LiFePO4. He mea laha ʻole a he pipiʻi hoʻi kēia mau mea ʻelua, a aia nā pilikia kaiapuni a me nā pono e pili ana i ka eli ʻana iā lākou. ʻO kēia ka mea e lilo ai nā pila LiFePO4 i ʻano pila ʻōmaʻomaʻo me ka emi ʻana o ka hakakā e pili ana i kā lākou mau mea.

ʻO ka pōmaikaʻi nui hope loa o kēia mau pila ʻo ko lākou palekana hoʻohālikelike ʻia me nā kemika pila lithium ʻē aʻe. Ua heluhelu paha ʻoe e pili ana i ke ahi ʻana o ka pila lithium i nā polokalamu e like me nā kelepona akamai a me nā papa kaulike.

ʻOi aku ka paʻa o nā pila LiFePO4 ma mua o nā ʻano pila lithium ʻē aʻe. He paʻakikī ke hoʻā ʻia, ʻoi aku ka maikaʻi o ka hoʻokele ʻana i nā mahana kiʻekiʻe a ʻaʻole e pala e like me nā kemika lithium ʻē aʻe.

No ke aha mākou e ʻike nei i kēia mau pila i kēia manawa?

Ua paʻi mua ʻia ka manaʻo no nā pila LiFePO4 i ka makahiki 1996, akā ʻaʻole a hiki i ka makahiki 2003 i lilo ai kēia mau pila i mea kūpono maoli, mahalo i ka hoʻohana ʻana i nā nanotubes kalapona. Mai ia manawa, ua lōʻihi ka manawa no ka hoʻonui ʻana i ka hana nui ʻana, nā kumukūʻai e lilo i mea hoʻokūkū, a ua maopopo nā hihia hoʻohana maikaʻi loa no kēia mau pila.

I ka hopena o nā makahiki 2010 a me ka hoʻomaka ʻana o nā makahiki 2020 wale nō i loaʻa ai nā huahana kalepa me ka ʻenehana LiFePO4 ma nā papa a ma nā pūnaewele e like me Amazon.

I ka manawa hea e noʻonoʻo ai iā LiFePO4

Ma muli o ko lākou haʻahaʻa o ka ikehu, ʻaʻole maikaʻi nā pila LiFePO4 no ka ʻenehana lawe lima lahilahi a māmā. No laila, ʻaʻole ʻoe e ʻike iā lākou ma nā kelepona akamai, nā papa, a i ʻole nā ​​​​kamepiula kamepiula. Ma ka liʻiliʻi ʻaʻole i kēia manawa.

Eia nō naʻe, i ke kamaʻilio ʻana e pili ana i nā hāmeʻa āu e pono ʻole ai e lawe pū me ʻoe, ʻaʻole nui ka nui o kēlā ʻano haʻahaʻa. Inā ʻoe e ʻimi nei e kūʻai i kahi UPS (Uninterruptible Power Supply) e hoʻomau i kāu router a i ʻole ke kahua hana i ka wā e pau ai ka mana, he koho maikaʻi loa ʻo LiFePO4.

ʻOiaʻiʻo, ke hoʻomaka nei ʻo LiFePO4 e lilo i koho makemake ʻia no nā noi kahi i ʻoi aku ka maikaʻi o nā pila waikawa kēpau e like me nā mea a mākou e hoʻohana ai i nā kaʻa. ʻO ia hoʻi ka mālama ʻana i ka mana o ka lā ma ka home a i ʻole nā ​​​​​​kākoʻo mana i hoʻopaʻa ʻia i ka grid. ʻOi aku ke kaumaha o nā pila waikawa kēpau, ʻaʻole nui ka ikehu, he pōkole loa ke ola, he ʻawahia, a ʻaʻole hiki ke lawelawe i nā hoʻokuʻu hohonu hou me ka ʻole o ka hōʻino ʻana.

Ke kūʻai ʻoe i nā mea hana mana o ka lā e like me ke kukui lā, a loaʻa iā ʻoe ke koho e hoʻohana iā LiFePO4, ʻo ia ke koho kūpono i nā manawa a pau. Hiki i ka mea hana ke hana no nā makahiki me ka ʻole o ka mālama ʻana.
