Nā pila lithium Ternary a menā pila lithium hao phosphateʻo ia nā ʻano nui ʻelua o nā pila lithium i hoʻohana nui ʻia i kēia manawa i nā kaʻa uila, nā ʻōnaehana mālama ikehu a me nā mea uila ʻē aʻe. Akā ua maopopo anei iā ʻoe ko lākou mau ʻano a me nā ʻokoʻa? He ʻokoʻa loa ko lākou ʻano kemika, nā ʻano hana a me nā kahua noi. E aʻo hou kākou e pili ana iā lākou me Heltec.
ʻAno mea:
Pākahi lithium Ternary: ʻO ka mea electrode maikaʻi he nickel, cobalt, manganese oxide (NCM) a i ʻole nickel, cobalt, aluminum oxide (NCA), i haku ʻia me ka nickel, cobalt, manganese a i ʻole nickel, cobalt, alumini a me nā mea metala ʻē aʻe oxides, a ʻo ka electrode maikaʻi ʻole he graphite. I waena o lākou, hiki ke hoʻoponopono ʻia ka lakio o ka nickel, cobalt, manganese (a i ʻole alumini) e like me nā pono maoli.
Pākahiko hao phosphate Lithium: hoʻohana ʻia ka lithium hao phosphate (LiFePO₄) ma ke ʻano he mea electrode maikaʻi, a hoʻohana ʻia hoʻi ka graphite no ka electrode maikaʻi ʻole. He paʻa kona ʻano kemika, a ʻaʻohe ona metala kaumaha a me nā metala kakaikahi, ʻoi aku ka launa pū me ke kaiapuni.
Ka hana hoʻouka a me ka hoʻokuʻu ʻana:
Pākahi lithium Ternary: wikiwiki ka hoʻouka a me ka wikiwiki o ka hoʻokuʻu ʻana, hiki ke hoʻololi i ka hoʻouka a me ka hoʻokuʻu ʻana o kēia manawa kiʻekiʻe, kūpono no nā lako a me nā hiʻohiʻona me nā koi kiʻekiʻe no ka wikiwiki o ka hoʻouka ʻana, e like me nā kaʻa uila e kākoʻo ana i ka hoʻouka wikiwiki. I ke kaiapuni haʻahaʻa, maikaʻi nō hoʻi kāna hana hoʻouka a me ka hoʻokuʻu ʻana, a liʻiliʻi ka pohō o ka mana.
Pākahiko hao phosphate Lithium: lohi iki ka wikiwiki o ka hoʻouka a me ka hoʻokuʻu ʻana, akā paʻa ka hana hoʻouka a me ka hoʻokuʻu ʻana o ke kaʻina hana. Hiki iā ia ke kākoʻo i ka hoʻouka wikiwiki a hiki ke hoʻouka piha ʻia i loko o 1 hola ma ka wikiwiki loa, akā ʻo ka pono o ka hoʻouka a me ka hoʻokuʻu ʻana ma kahi o 80%, ʻoi aku ka haʻahaʻa ma mua o ka pākahi lithium ternary. Ma lalo o nā kūlana mahana haʻahaʻa, emi nui kāna hana, a ʻo ka helu paʻa o ka mana o ka pākahiko he 50%-60% wale nō paha.
Ka nui o ka ikehu:
Pākahi lithium Ternary: Kiʻekiʻe iki ka nui o ka ikehu, ʻoi aku ma mua o 200Wh/kg, a hiki i kekahi mau huahana holomua ke ʻoi aku ma mua o 260Wh/kg. ʻAe kēia i nā pākahi lithium ternary e mālama i ka ikehu hou aʻe ma ka nui like a i ʻole ke kaumaha like, e hāʻawi ana i kahi mamao hoʻokele lōʻihi no nā mea hana, e like me nā kaʻa uila, hiki ke kākoʻo i nā kaʻa e hele i nā wahi lōʻihi.
Pākahi hao phosphate Lithium: He haʻahaʻa iki ka nui o ka ikehu, ma kahi o 110-150Wh/kg. No laila, i mea e hoʻokō ai i ka laulā hoʻokele like me nā pākahi lithium ternary, pono paha i nā pākahi hao phosphate lithium ka nui a i ʻole ke kaumaha.
Ola pōʻaiapuni:
Pākahi lithium Ternary: He pōkole ke ola pōʻaiapuni, me ka helu pōʻaiapuni kumumanaʻo o kahi 2,000 mau manawa. I ka hoʻohana maoli ʻana, ua emi paha ka mana i kahi 60% ma hope o 1,000 mau pōʻaiapuni. ʻO ka hoʻohana pono ʻole, e like me ka hoʻouka nui ʻana a i ʻole ka hoʻokuʻu ʻana, a me ka hoʻohana ʻana i nā wahi mahana kiʻekiʻe, e hoʻolalelale i ka palaho o ka pākaukau.
Pākahi hao phosphate Lithium: Ola lōʻihi, me nā pōʻaiapuni hoʻouka a hoʻokuʻu ma mua o 3,500, a hiki i kekahi mau pākahiko kiʻekiʻe ke piʻi aku ma mua o 5,000 mau manawa, ʻo ia hoʻi ma mua o 10 mau makahiki o ka hoʻohana ʻana. Loaʻa iā ia ke kūpaʻa lattice maikaʻi, a ʻo ka hoʻokomo ʻana a me ka wehe ʻana i nā ion lithium he hopena liʻiliʻi i ka lattice, a he hoʻihoʻi maikaʻi.
Palekana:
Pākahi lithium Ternary: kūpaʻa wela maikaʻi ʻole, maʻalahi ke hoʻoulu i ka holo ʻana o ka wela ma lalo o ke kiʻekiʻe o ka mahana, ka hoʻouka nui ʻana, ka pōʻai pōkole a me nā kūlana ʻē aʻe, e hopena ana i kahi pilikia kiʻekiʻe o ke kuni ʻana a i ʻole ka pahū ʻana. Eia nō naʻe, me ka holomua o ka ʻenehana a me ka hoʻoikaika ʻana i nā hana palekana, e like me ka hoʻohana ʻana i nā ʻōnaehana hoʻokele pākaukau holomua a me ka hoʻonui ʻana i ka hoʻonohonoho ʻana o ka pākaukau, ke hoʻomaikaʻi mau nei kona palekana.
Pākahi hao phosphate lithium: kūpaʻa maikaʻi ka wela, ʻaʻole maʻalahi ka hoʻokuʻu ʻana o ka oxygen i ka mahana kiʻekiʻe o ka mea electrode maikaʻi, a ʻaʻole e hoʻomaka e pala a hiki i ka 700-800 ℃, a ʻaʻole e hoʻokuʻu i nā molekole oxygen i ka wā e kū ai i ka hopena, ka puncture, ka pōʻai pōkole a me nā kūlana ʻē aʻe, a ʻaʻole ia e maʻalahi i ka puhi ʻino, me ka hana palekana kiʻekiʻe.
Kumukūʻai:
ʻO ka pākahiko lithium Ternary: no ka mea, aia nā mea metala pipiʻi e like me ka nickel a me ka cobalt i loko o ka mea electrode maikaʻi, a kiʻekiʻe nā koi o ke kaʻina hana, a ʻoi aku ka paʻakikī o nā koi o ke kaiapuni, no laila kiʻekiʻe ke kumukūʻai.
Pākahiko hao phosphate Lithium: he haʻahaʻa ke kumukūʻai o nā mea maka, he maʻalahi ke kaʻina hana, a he mau pono ko ke kumukūʻai holoʻokoʻa. No ka laʻana, i nā kaʻa ikehu hou, ʻo nā hiʻohiʻona i lako me nā pila lithium hao phosphate he haʻahaʻa pinepine ke kumukūʻai.
Hopena
ʻO ke koho ʻana o ka pila e hilinaʻi nui ʻia ma nā koi noi kikoʻī. Inā koi ʻia ka nui o ka ikehu a me ke ola lōʻihi o ka pila, ʻoi aku ka maikaʻi o nā pila lithium ternary; inā ʻo ka palekana, ka lōʻihi a me ke ola lōʻihi nā mea nui, ʻoi aku ka kūpono o nā pila lithium hao phosphate.
ʻO Heltec Energy kāu hoa hilinaʻi mapūʻolo pilahana ʻana. Me kā mākou nānā mau ʻana i ka noiʻi a me ka hoʻomohala ʻana, me kā mākou laulā piha o nā mea pono pākahi, hāʻawi mākou i nā hopena hoʻokahi e hoʻokō i nā pono e ulu nei o ka ʻoihana. ʻO kā mākou kūpaʻa i ka maikaʻi loa, nā hoʻonā i hana kūikawā ʻia, a me nā hui pū ʻana o nā mea kūʻai aku ikaika e hoʻolilo iā mākou i koho koho no nā mea hana a me nā mea hoʻolako pūʻolo pākahi ma ka honua holoʻokoʻa.
Inā he mau nīnau kāu a makemake paha e ʻike hou aku, mai kānalua e leka uila mai iā mākoue hoʻokaʻaʻike mai iā mākou.
