Kapa ʻia ka puʻuwai mana ʻo ka puʻuwai o kahi kaʻa uila; ʻo ka hōʻailona, mea waiwai, ka hiki, ka hana palekana, a me nā mea ʻē aʻe o ka pā uila o kahi kaʻa uila ua lilo i "nā ana" a me nā "parameter" no ke ana ʻana i kahi kaʻa uila. I kēia manawa, ʻo ke kumukūʻai pākaukau o kahi kaʻa uila he 30% -40% o ka kaʻa holoʻokoʻa, hiki ke ʻōlelo ʻia he mea kōkua nui!
I kēia manawa, ua hoʻokaʻawale ʻia nā pihi mana nui i hoʻohana ʻia i nā kaʻa uila ma ka mākeke i ʻelua mau ʻano: nā pākahi lithium ternary a me nā pākahi lithium iron phosphate. Ma hope aʻe, e ʻae mai iaʻu e loiloi pōkole i nā ʻokoʻa a me nā pono a me nā pōʻino o nā ʻāpana ʻelua:
1. Nā mea like ʻole:
ʻO ke kumu i kapa ʻia ai ʻo "ternary lithium" a me "lithium iron phosphate" e pili ana i nā mea kemika o ka "mea electrode maikaʻi" o ka pā mana;
"Ternary lithium":
Hoʻohana ka mea cathode i ka lithium nickel cobalt manganate (Li(NiCoMn)O2) ternary cathode material no nā pā lithium. Hoʻohui kēia mea i nā pono o ka lithium cobalt oxide, lithium nickel oxide a me ka lithium manganate, e hana ana i kahi ʻōnaehana eutectic ʻekolu o nā mea ʻekolu. Ma muli o ka hopena synergistic ternary, ʻoi aku ka maikaʻi o kāna hana holoʻokoʻa ma mua o nā hui hui hoʻokahi.
"Lithium hao phosphate":
e pili ana i nā pākahi lithium-ion e hoʻohana ana i ka lithium iron phosphate e like me ka mea cathode. ʻO kona mau hiʻohiʻona ʻaʻole i loaʻa nā mea metala makamae e like me ka cobalt, haʻahaʻa ke kumu kūʻai kumu, a nui nā kumu waiwai o ka phosphorus a me ka hao ma ka honua, no laila ʻaʻohe pilikia o ka lako.
hōʻuluʻulu manaʻo
He liʻiliʻi nā mea lithium Ternary a ke piʻi nei me ka ulu wikiwiki o nā kaʻa uila. He kiʻekiʻe ko lākou kumukūʻai a ua kaupalena ʻia lākou e nā mea maka. He ʻano kēia o ka lithium ternary i kēia manawa;
Lithium iron phosphate, no ka mea, hoʻohana ʻo ia i ka ratio haʻahaʻa o nā metala makamae a ʻoi aku ka haʻahaʻa a me ka hao nui, ʻoi aku ka liʻiliʻi ma mua o nā ʻeke lithium ternary a ʻaʻole i hoʻopilikia ʻia e nā mea maka. ʻO kēia kona ʻano.
2. ʻOkoʻa ikehu densities:
"Ternary lithium battery": Ma muli o ka hoʻohana ʻana i nā mea metala ʻoi aku ka ikaika, ʻo ka nui o ka ikehu o nā pākahi lithium ternary maʻamau maʻamau (140wh / kg ~ 160 wh / kg), ʻoi aku ka haʻahaʻa ma mua o nā pākahi ternary me ka ratio nickel kiʻekiʻe ( 160 wh/ kg～180 wh/kg); hiki ke hiki i ka 180Wh-240Wh/kg kekahi kaumaha o ka ikehu.
"Lithium iron phosphate": ʻO ka nui o ka ikehu he 90-110 W/kg; ʻO kekahi mau pahu lithium iron phosphate hou, e like me nā ʻāpana ʻōpala, loaʻa ka ikehu a hiki i 120W/kg-140W/kg.
hōʻuluʻulu manaʻo
ʻO ka pōmaikaʻi nui loa o ka "ternary lithium battery" ma luna o ka "lithium iron phosphate" ʻo ia ke kiʻekiʻe o ka ikehu kiʻekiʻe a me ka wikiwiki o ka hoʻouka ʻana.
3. Hiki ke hoʻololi i ka mahana like ʻole:
Palena haʻahaʻa wela:
ʻO Ternary lithium battery: He hana haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ka Ternary lithium a hiki ke mālama i kahi 70% ~ 80% o ka mana pākaukau maʻamau ma -20°C.
Lithium iron phosphate: ʻAʻole kūpaʻa i nā mahana haʻahaʻa: Ke emi ka mahana ma lalo o -10°C,
Popopo koke nā ʻaʻa lithium hao phosphate. Hiki i nā ʻona lithium hao phosphate ke mālama i kahi o 50% a i 60% o ka mana pākahi maʻamau ma -20°C.
hōʻuluʻulu manaʻo
Aia kekahi ʻokoʻa nui i ka hiki ke hoʻololi i ka mahana ma waena o "ternary lithium battery" a me "lithium iron phosphate"; ʻOi aku ka pale ʻana o ka "lithium iron phosphate" i nā wela kiʻekiʻe; a ʻoi aku ka maikaʻi o ke ola pākaukau ma nā wahi ʻākau a i ʻole ka hoʻoilo o ka "ternary lithium battery" haʻahaʻa haʻahaʻa.
4. ʻOkoʻa nā manawa ola:
Inā hoʻohana ʻia ke koena o ka mana/hiki mua = 80% ma ke ʻano o ka helu hoʻāʻo, e hoʻāʻo:
ʻOi aku ka lōʻihi o ke ola pōʻaiapuni ʻana o nā pūʻolo pākahi lithium iron phosphate ma mua o nā ʻakika lead-acid a me nā pākahi lithium ternary. ʻO ka "ola lōʻihi loa" o kā mākou mau pahu pahu lead-acid i kau ʻia ma kahi kaʻa he 300 wale nō; hiki i ka pila lithium ternary ke hoʻomau i nā manawa 2,000, akā i ka hoʻohana maoli ʻana, e pohō ka mana i 60% ma hope o 1,000 mau manawa; a ʻo ke ola maoli o nā pākahi lithium hao phosphate he 2000 mau manawa, aia nō ka 95% hiki i kēia manawa, a ʻoi aku kona ola pōʻaiapili ma mua o 3000 mau manawa.
hōʻuluʻulu manaʻo
ʻO nā pihi mana ka piko o ka ʻenehana o nā pila. ʻO nā ʻano pākahi lithium ʻelua he mau lōʻihi. Ma ka ʻōlelo ʻana, ʻo ke ola o kahi pākahi lithium ternary he 2,000 ka hoʻoiho a me ka hoʻokuʻu ʻana. ʻOiai inā mākou e hoʻopaʻa iā ia i hoʻokahi manawa i ka lā, hiki ke lōʻihi ma mua o 5 mau makahiki.
5. He okoa na kumu kuai:
No ka mea, ʻaʻole i loaʻa i nā pākahi lithium iron phosphate nā mea metala makamae, hiki ke hoʻemi haʻahaʻa loa ke kumukūʻai o nā mea maka. Hoʻohana ʻia nā ʻeke lithium Ternary i ka lithium nickel cobalt manganate ma ke ʻano he mea electrode maikaʻi a me ka graphite ma ke ʻano he mea electrode maikaʻi ʻole, no laila ʻoi aku ka maikaʻi o ke kumukūʻai ma mua o nā pākahi lithium hao phosphate.
Hoʻohana nui ʻia ka pākaukau lithium ternary i ka mea cathode ternary o "lithium nickel cobalt manganate" a i ʻole "lithium nickel cobalt aluminate" ma ke ʻano he electrode maikaʻi, me ka hoʻohana nui ʻana i ka paʻakai nickel, ka paʻakai cobalt, a me ka paʻakai manganese ma ke ʻano he kumu. ʻO ka "kobalt element" i loko o kēia mau mea cathode ʻelua he metala makamae. Wahi a nā ʻikepili mai nā pūnaewele kūpono, ʻo ke kumukūʻai kūʻai kūloko o ka metala cobalt he 413,000 yuan / ton, a me ka hoʻemi ʻana o nā mea waiwai, ke piʻi mau nei ke kumukūʻai. I kēia manawa, he 0.85-1 yuan/wh ke kumu kūʻai o nā pākahi lithium ternary, a ke piʻi nei i kēia manawa me ka noi mākeke; ʻO ke kumu kūʻai o nā pākahi lithium hao phosphate ʻaʻole i loaʻa nā mea metala makamae ma kahi o 0.58-0.6 yuan/wh wale nō.
hōʻuluʻulu manaʻo
No ka mea, ʻaʻole i loaʻa i ka "lithium iron phosphate" nā metala makamae e like me ka cobalt, ʻo kona kumukūʻai he 0.5-0.7 wale nō ka nui o nā pākahi lithium ternary; ʻO ke kumu kūʻai liʻiliʻi kahi pono nui o ka lithium iron phosphate.
Hōʻuluʻulu
ʻO ke kumu o ka ulu ʻana o nā kaʻa uila i nā makahiki i hala iho nei a ke hōʻike nei i ke ala e hiki mai ana o ka hoʻomohala ʻana i nā kaʻa, e hāʻawi ana i nā mea kūʻai aku i ʻoi aku ka maikaʻi o ka ʻike, ʻo ia ka mea ma muli o ka hoʻomau mau ʻana o ka ʻenehana uila mana.
