ʻO ka pākaukau lithium iron phosphate a me ka pākahi lithium ternary, ʻoi aku ka maikaʻi?

Ke neʻe nei mākou i kahi maʻemaʻe, ʻōmaʻomaʻo i ka wā e hiki mai ana, e ulu wikiwiki ana ka pono o nā ʻōnaehana mālama ikehu hoʻomau.ʻO kekahi o nā ʻenehana hoʻohiki ʻia ʻo nā pā lithium-ion, e loaʻa ana ka kaulana ma muli o ko lākou kiʻekiʻe o ka ikehu a me ka lōʻihi o ke ola ʻana i hoʻohālikelike ʻia i nā pākaukau lead-acid.Iloko o kapākaukau lithium-ionʻohana, ʻo nā ʻano nui ʻelua i hoʻohālikelike pinepine ʻia ʻo ia nā ʻeke lithium iron phosphate (LiFePO4) a me nā pihi lithium ternary.No laila, e ʻeli hohonu kākou: ʻo wai ka maikaʻi?

E pili ana i nā pākahi lithium hao phosphate

Ua ʻike ʻia nā pākahi Lithium iron phosphate (LiFePO4) no ko lākou kūpaʻa, palekana, a me ke ola pōʻai lōʻihi.He pākaukau hoʻihoʻi ia e hoʻohana ana i nā ion lithium e mālama a hoʻokuʻu i ka ikehu i ka wā o ka hoʻouka a me ka hoʻokuʻu ʻana.Ke hoʻohālikelike ʻia me nā pākahi lithium ternary, ʻoi aku ka haʻahaʻa o ka ikehu haʻahaʻa o nā pā lithium iron phosphate, akā ʻo ko lākou kūpaʻa a me ke ola e hoʻopau i kēia hemahema.Loaʻa i kēia mau pila ke kūpaʻa wela kiʻekiʻe, hiki iā lākou ke kūpaʻa i ka wela a hōʻemi i ka hopena o ka holo ʻana o ka wela, kahi hopohopo nui no nā noi he nui.Eia hou, hiki i nā ʻokoʻa LiFePO4 ke kūpaʻa maʻamau i nā pōʻai kiʻekiʻe a me ka hoʻokuʻu ʻana, a hiki i 2000 mau pōʻai a ʻoi aku paha, e hoʻolilo iā lākou i mea kūpono no ka wā lōʻihi, nā noi hana kiʻekiʻe e like me nā kaʻa uila (EV).

E pili ana i nā pākahi lithium ternary

Ma ka ʻaoʻao ʻē aʻe, ʻo nā pākahi lithium ternary, i ʻike ʻia ʻo lithium nickel-cobalt-aluminum oxide (NCA) a i ʻole lithium nickel-manganese-cobalt oxide (NMC), hāʻawi i nā density ikehu kiʻekiʻe aʻe ma mua o nā pākahi LiFePO4.ʻOi aku ka nui o ka ikehu e hiki ai ke hoʻonui i ka mana mālama a me ka lōʻihi o ka holo ʻana o ka mīkini.Hoʻohui ʻia, hāʻawi maʻamau nā pākahi lithium ternary i ka mana mana kiʻekiʻe, e kūpono ana iā lākou no nā noi e koi ana i ka wikiwiki o ka ikehu, e like me nā mea hana mana a i ʻole nā ​​​​mea uila uila.Eia nō naʻe, i ka piʻi ʻana o ka ikehu, aia kekahi mau kālepa.ʻOi aku ka pōkole o ke ola lawelawe ʻana o nā pākahi lithium Ternary a ʻoi aku ka maʻalahi i nā pilikia wela a me ka paʻa ʻole ma mua o nā pā LiFePO4.

ʻO ka hoʻoholo ʻana i ka pākaukau ʻoi aku ka maikaʻi ma muli o nā koi o ka noi kikoʻī.Ma kahi o ka palekana a me ke ola lōʻihi ka mea nui, e like me nā kaʻa uila a i ʻole nā ​​​​pūnaewele ikehu hou, ʻo nā pā lithium hao phosphate ka koho mua.ʻO ke kūpaʻa, ka lōʻihi o ke ola holoʻokoʻa, a me ke kūpaʻa ʻana i ka holo ʻana o ka wela o nā pākahi LiFePO4 e lilo lākou i koho maikaʻi loa no nā noi koʻikoʻi kahi i ʻoi aku ka palekana.Eia kekahi, no nā noi e koi ana i ka mana hoʻomau kiʻekiʻe a i ʻole nā ​​​​mea koʻikoʻi ke kaumaha a me ka lewa, ʻoi aku ka maikaʻi o nā pākahi lithium ternary ma muli o ko lākou kiʻekiʻe o ka ikehu.

Loaʻa i nā ʻano ʻokoʻa ʻelua nā pono a me nā hemahema, a pono e noʻonoʻo pono i nā koi kikoʻī o kahi noi ma mua o ka hoʻoholo ʻana.Pono e noʻonoʻo ʻia nā mea e like me ka palekana, ke ola, ka nui o ka ikehu, ka mana mana, a me ke kumukūʻai.

I ka hōʻuluʻulu ʻana, ʻaʻohe mea lanakila ma ka hoʻopaʻapaʻa ʻana ma waena o nā pākahi lithium hao phosphate a me nā pākahi lithium ternary.Loaʻa i kēlā me kēia ala kona mau pono a me nā hemahema, a ʻo ke koho e pili ana i nā pono o ka noi kikoʻī.Ke hoʻomau nei ka hoʻomohala ʻana o ka ʻenehana, e hoʻomaikaʻi ʻia nā ʻano ʻelua o nā ʻāpana Li-ion ma ke ʻano o ka hana, palekana a me ka pono holoʻokoʻa.ʻAʻohe mea pili i ka pākaukau āu e koho ai, he mea nui ia e hoʻomau i ka ʻapo ʻana a me ka hoʻopukapuka ʻana i nā ʻōnaehana mālama ikehu hoʻomau a pili i ke kaiapuni e hāʻawi i kahi ʻōmaʻomaʻo no nā mea a pau.

Inā makemake ʻoe i nā pākahi lithium, e ʻoluʻolu e hoʻokaʻaʻike i ka hui pākaukau lithium Radiance iheluhelu hou.
