ʻO nā pākahi lithium Ternary a meʻo nā ʻanuʻu lithium hao phosphateʻO ia nā ʻano nui ʻelua o nā pākahi lithium i hoʻohana nui ʻia 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? ʻOkoʻa ko lākou ʻano kemika, nā hiʻohiʻona hana a me nā kahua noi. E aʻo hou e pili ana iā lākou me Heltec.
Mea haku mele:
ʻO ka pahu lithium Ternary: ʻO ka mea electrode maikaʻi he nickel cobalt manganese oxide (NCM) a i ʻole nickel cobalt alumina oxide (NCA), i haku ʻia me ka nickel, cobalt, manganese a i ʻole nickel, cobalt, aluminika a me nā mea metala ʻē aʻe, a me nā mea ʻino. ʻO ka electrode ka graphite maʻamau. I waena o lākou, hiki ke hoʻoponopono ʻia ka ratio o ka nickel, cobalt, manganese (a i ʻole alumini) e like me nā pono maoli.
Lithium iron phosphate pākaukau: lithium iron phosphate (LiFePO₄) hoʻohana ʻia e like me ka mea electrode maikaʻi, a hoʻohana pū ʻia ka graphite no ka electrode maikaʻi ʻole. Paʻa kona ʻano kemika, ʻaʻole i loko o nā metala kaumaha a me nā metala kakaʻikahi, ʻoi aku ka maikaʻi o ke kaiapuni.
Ka hoʻokō a me ka hoʻokuʻu ʻana:
ʻO Ternary lithium battery: ka wikiwiki wikiwiki a me ka hoʻokuʻu ʻana i ka wikiwiki, hiki ke hoʻololi i ka uku kiʻekiʻe o kēia manawa a me ka hoʻokuʻu ʻana, kūpono no nā lako a me nā hiʻohiʻona me nā koi kiʻekiʻe no ka hoʻouka ʻana i ka wikiwiki, e like me nā kaʻa uila e kākoʻo ana i ka hoʻopiʻi wikiwiki. Ma ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, kona uku a me ka hoʻokuʻu ʻana o ka hana ʻoi aku ka maikaʻi, a he liʻiliʻi ka nalowale o ka hiki.
Lithium iron phosphate pākahiko: lohi lohi a me ka hoʻokuʻu ʻana i ka wikiwiki, akā paʻa ka hoʻopiʻi ʻana a me ka hana hoʻokuʻu. Hiki iā ia ke kākoʻo i ka hoʻopiʻi kiʻekiʻe a hiki ke hoʻopiha piha ʻia i ka hola 1 i ka wikiwiki, akā ʻo ka hoʻopiʻi 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 haʻahaʻa haʻahaʻa, emi nui kāna hana, a ʻo ka nui o ka paʻa ʻana o ka pākaukau he 50% -60% wale nō.
ʻAno ikaika:
Ternary lithium battery: He kiʻekiʻe ke kiʻekiʻe o ka ikehu, ʻoi aku ka maʻamau ma mua o 200Wh/kg, a hiki i kekahi mau huahana holomua ke ʻoi aku ma mua o 260Wh/kg. ʻO kēia ka mea e hiki ai i nā pākahi lithium ternary ke mālama i ka ikehu ma ka leo like a i ʻole ke kaumaha, e hāʻawi ana i ka lōʻihi o ka holo kaʻa no nā mea hana, e like me nā kaʻa uila, hiki ke kākoʻo i nā kaʻa e hele i kahi lōʻihi.
Lithium iron phosphate pākaukau: He haʻahaʻa ka nui o ka ikehu, ma kahi o 110-150Wh/kg. No laila, i mea e hoʻokō ai i ke kaʻa kaʻa like e like me nā pākahi lithium ternary, pono paha nā pākahi lithium iron phosphate i ka nui a i ʻole ke kaumaha.
Ke ola pōʻaiapuni:
ʻO Ternary lithium battery: He pōkole ke ola pōʻaiapuni, me ka helu pōʻaiapuni kumu o 2,000 mau manawa. I ka hoʻohana maoli ʻana, ua pohō paha ka mana ma kahi o 60% ma hope o 1,000 cycles. ʻO ka hoʻohana pono ʻole, e like me ka hoʻouka ʻana a i ʻole ka hoʻokuʻu ʻana, a me ka hoʻohana ʻana i nā wahi wela kiʻekiʻe, e hoʻolalelale i ka pohō o ka pākaukau.
Lithium iron phosphate battery: ʻO ke ola pōʻai lōʻihi, me ka ʻoi aku ma mua o 3,500 ka hoʻoiho a me ka hoʻokuʻu ʻana, a hiki i kekahi mau pahu kiʻekiʻe kiʻekiʻe ke piʻi aku ma mua o 5,000 mau manawa, ʻo ia ka mea e like me 10 mau makahiki o ka hoʻohana ʻana. Loaʻa iā ia ka paʻa o ka lattice maikaʻi, a ʻo ka hoʻokomo ʻana a me ka wehe ʻana i nā ion lithium he hopena liʻiliʻi ma ka lattice, a he maikaʻi ke hoʻololi.
Palekana:
ʻO ka pahu lithium Ternary: maikaʻi ʻole ka wela wela, maʻalahi ke hoʻokuʻu i ka wela ma lalo o ke kiʻekiʻe o ka wela, ka overcharge, ka pōkole pōkole a me nā kūlana ʻē aʻe, e hopena i kahi hopena kiʻekiʻe o ka puhi ʻana a i ʻole ka pahū. 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 ʻoi aku ka maikaʻi a me ka hoʻonui ʻana i ka hoʻolālā pākaukau, ke hoʻomaikaʻi mau nei kona palekana.
Lithium iron phosphate pākaukau: maikaʻi thermal stability, ʻaʻole maʻalahi ka mea electrode maikaʻi e hoʻokuʻu i ka oxygen i ke kiʻekiʻe kiʻekiʻe, ʻaʻole e hoʻomaka e decompose a hiki i 700-800 ℃, ʻaʻole e hoʻokuʻu i nā moleke oxygen i ka wā e kū ana i ka hopena, puncture, pōkole pōkole a nā kūlana ʻē aʻe, a ʻaʻole maʻalahi i ka puhi ʻino, me ka hana palekana kiʻekiʻe.
Koina:
ʻO Ternary lithium battery: no ka mea, aia ka mea electrode maikaʻi i nā mea metala makamae e like me ka nickel a me ka cobalt, a ʻoi aku ka kiʻekiʻe o ke kaʻina hana, a ʻoi aku ka paʻakikī o ke kaiapuni, no laila ke kiʻekiʻe ke kumukūʻai.
Lithium iron phosphate pākahiko: he haʻahaʻa haʻahaʻa ke kumukūʻai o nā mea maka, maʻalahi ke kaʻina hana, a ʻo ke kumukūʻai holoʻokoʻa he mau pono. No ka laʻana, i nā kaʻa ikehu hou, ʻoi aku ka haʻahaʻa o nā kumu hoʻohālike me nā pākahi lithium hao phosphate.
Ka hopena
ʻO ke koho ʻana o ka pākaukau e hilinaʻi nui ʻia i nā koi noi kikoʻī. Inā makemake ʻia ka nui o ka ikehu a me ka lōʻihi o ke ola pākaukau, ʻoi aku ka maikaʻi o nā pākahi lithium ternary; inā ʻo ka palekana, ka lōʻihi a me ke ola lōʻihi ka mea nui, ʻoi aku ka maikaʻi o nā pākahi lithium hao phosphate.
ʻO Heltec Energy kāu hoa hilinaʻipūʻolo pilahana hana. Me ko mākou manaʻo hoʻomau i ka noiʻi a me ka hoʻomohala ʻana, i hui pū ʻia me kā mākou ʻāpana piha o nā lako pākaukau, hāʻawi mākou i nā ʻoluʻolu hoʻokahi e hoʻokō i nā pono e ulu nei o ka ʻoihana. ʻO kā mākou kūpaʻa i ka maikaʻi, nā hoʻonā i hoʻohālikelike ʻia, a me nā hui kūʻai ikaika e hoʻolilo iā mākou i ke koho koho no nā mea hana pākaukau a me nā mea hoʻolako ma ka honua holoʻokoʻa.
Inā he mau nīnau kāu a makemake paha e aʻo hou aku, e ʻoluʻolu e ʻoluʻolue kikoo mai ia makou.
