ʻAʻole maopopo iaʻu pehea ka holo ʻana o ka pā lithium i ke kaʻa uila.

Mea kākau:Iflowpower –Mea Hoolako Uila Uila

ʻO ka pākaukau ka ʻuhane o nā kaʻa uila, ʻaʻohe pā, ʻaʻole hiki i nā kaʻa uila ke hōʻike i kona ʻokoʻa. Ma ke kumukūʻai holoʻokoʻa o kahi kaʻa uila, hiki i ka pākaukau ke helu no 30% -45% o ke kumukūʻai, ʻo ke kaʻa, a me ka mana uila no 20% -25%, ʻo ke kino a me nā ʻāpana ʻē aʻe he 20%. Hōʻike kēia i ke koʻikoʻi o ka pākaukau! No laila, ʻo ka pākaukau kekahi mea i nānā ʻia e nā mea hana kaʻa nui.

No laila, he aha ke ʻano o ka pākaukau nui i kēia manawa ma ka mākeke? ʻEhā mau ʻano o ʻehā: ʻekolu-dimensional lithium ion pākahiko, lithium iron phosphate ion battery, lead-acid battery and lithium-ion battery. ʻO ka pāʻani lithium-ion ʻekolu-dimensional lithium ion ʻekolu-dimensional polymer lithium-ion pākahiko, e like me ka inoa i hōʻike ʻia, ua hoʻokumu ʻia ma ka nickel-salt, cobalt salt, manganese paʻakai ma ke ʻano he mea electrode maikaʻi e like me ka maikaʻi. mea electrode, a hoʻohana ʻia ka mea ternary ma ke ʻano he electrode maikaʻi. ʻOi aku ka kiʻekiʻe o ka palekana o ka pākaukau ma mua o ka pā lithium cobalt ion, ʻo ia ka mea o nā mea hana pākaukau o kēia manawa.

Inā kūʻai ʻoe i kekahi mea, e nānā ka mea kūʻai aku i kona mau pono a me nā pōʻino i ke kūʻai ʻana, a makemake ʻo ia e kūʻai i nā pōmaikaʻi a me nā hemahema o nā waiwai, akā ʻo nā pono a me nā pōʻino o ka pā lithium-ion ʻekolu-yuan he mea maopopo loa, paʻakikī ke hoʻohana. ka huina hookolokolo. ʻO nā pōmaikaʻi koʻikoʻi o ka pākaukau lithium-ion ʻekolu-dimensional ʻo ia ka mea ʻoi aku ka kiʻekiʻe o ka ikehu koʻikoʻi ma mua o nā ʻano ʻokoʻa ʻē aʻe, ʻo ia hoʻi ke kaumaha like o ka pā lithium-ion ʻekolu-dimensional i hoʻohālikelike ʻia me nā ʻokoʻa ʻē aʻe, kona ola pākaukau. ʻoi aku ka nui o. Eia naʻe, ʻaʻole paʻa ka hale ma ke ʻano o ka wela kiʻekiʻe, no laila paʻakikī ke mālama ʻia ka palekana, a ʻoi aku ka kiʻekiʻe o ke kumukūʻai.

ʻOiai he nui ka poʻe i kēia manawa e nānā a hoʻohana i kēia pākaukau, ʻoi aku ka lōʻihi o kona hoʻomohala ʻana. Lithium iron phosphate ion pākaukau lithium iron phosphate ion pākaukau he lithium ion pākahi ma muli o ka lithium iron phosphate ma ke ʻano he mea electrode maikaʻi. E pili ana i ka pākaukau lithium-ion ʻekolu-dimensional, ʻoi aku ka kiʻekiʻe o ka palekana o ka pā lithium phosphate ion, ke kī PO i loko o nā kristal lithium hao phosphate, ʻoiai inā paʻakikī ke decompose i ka hihia o ka wela kiʻekiʻe a i ʻole overcharge, a hiki ke hoʻouka koke ʻia, hoʻohana ʻia Ke ola lōʻihi.

I ka manawa like, ua waiwai nui nā waihona lithium o koʻu ʻāina, ua nui hoʻi nā waihona o ka hao oxide phosphate oxide ma Kina, i loaʻa ka pōmaikaʻi maikaʻi i ka pā hao lithium iron o koʻu ʻāina, no laila makemake nui nā ʻoihana kūloko e koho i ka hoʻomohala ʻana a me ke aʻo ʻana. o ka hao phosphate. ʻO ka pākaukau Lithium-ion, e like me BYD, aia i loko o kēia pākaukau. I ka Qin kŘkohu hou, ua hoʻohana au i ka noiʻi hou loa a me ka hoʻomohala ʻana o nā ʻona lithium phosphate ion.

Ua hoʻohui kēia pākaukau i nā mea manganese, a ua hiki i kona ʻano ikehu i ka mānoanoa o ka mea ternary, a ua hoʻomaikaʻi maikaʻi ʻia i ke ola pākaukau. Eia naʻe, aia kahi pilikia nui me ka nui o nā mea nona nā kaʻa e hoʻopiʻi nei i ka volta a me ka mana o ka pākaukau. ʻO kēia mau helu ʻelua he mea koʻikoʻi nō hoʻi o nā pākahi lithium iron phosphate ion.

He haʻahaʻa ka nui o ka ikehu o ka pā lithium iron phosphate ion, ʻo ia ka mea e ʻoi aku ka nui o ka leo, a he liʻiliʻi ka leo o ka pākaukau, e lilo ai ke ola pākaukau i papa pōkole, a ʻaʻole hiki ke hoʻihoʻi i ka pila ma hope o ka ʻōpala. , hiki ke hoolei wale ia, he haahaa loa ka waiwai hana hou, i ka hopena, ua ilihune keia pila, a he pilikia nui no hoi ka hoouka ana o ka hooilo. No laila, inā makemake ʻo BYD e hoʻomau i ke alakaʻi ʻana i ka pākaukau, e uku nui ia. ʻO ka pākaukau lithium-cobalt-free o ka cobaltate ʻo Tesla ka "pākuʻi kūikawā", nona ka hale paʻa, ka mana kiʻekiʻe, a me ka hana holoʻokoʻa kiʻekiʻe.

Loaʻa iā ia kahi mana pākaukau maikaʻi, akā no ka liʻiliʻi o ka ʻāpana, hana ia i ke kaʻa ʻOi aku ka nui o ka nui o nā pila, ua kūkulu ʻo Tesla i ʻoi aku ma mua o 7,000 mau ʻāpana o ke kumu hoʻohālike o Models, 18650, ʻekolu-yuan lithium-ion pākahiko i lawa. e holo i ke kaa e holo. Ke piʻi ka mahana ponoʻī o ka pākaukau i 250-350 ¡ã C, ua hoʻomaka nā mea kemika o loko e palaha, a nui nā pōʻino palekana. I ka pane ʻana i kēia pilikia, ua hoʻomākaukau pū ʻo Tesla, a aia kahi fuse ma nā ʻaoʻao ʻelua o kēlā me kēia pākaukau.

Ke hoʻomāhana ʻia ka pākaukau a i ʻole ka nui o kēia manawa, e ʻoki ʻia ka fuse, e pale ana i ka pūʻolo pākahi holoʻokoʻa no ka mea ua pili ka pākaukau e kahi pā. puka mai. Eia nō naʻe, ʻoiai ʻo ka hopena theoretical ka mea maikaʻi loa, e pale maoli anei ia i nā noi kūpono? Eia kekahi, inā he pilikia me ka pūʻolo pākahiko holoʻokoʻa, pehea e hoʻoponopono ai? He pilikia nō hoʻi kēia e noʻonoʻo ai.

ʻO ka pākaukau lead-acid ʻo ia ke kanaka kahiko i loko o ka pā. Ua loaʻa iā ia kahi moʻolelo o 150 mau makahiki, a he mea nui kāna mau electrodes mai ke kēpau a me kāna mau oxides. I kēia manawa, ʻano ākea ka hoʻohana ʻana i nā pākī lead-acid no nā kaʻa uila haʻahaʻa.

ʻO ka pōmaikaʻi ʻo ia ka paʻa ʻana o ka volta, ka nui o ka hiki, a ākea ka pae wela. ʻAʻole ʻike ʻia i ka hihia o ka hoʻoilo koʻikoʻi, ua oʻo ka ʻenehana, kiʻekiʻe ka palekana, a haʻahaʻa ke kumukūʻai. Eia nō naʻe, ʻike nui ʻia nā hemahema o nā pākī lead-acid, haʻahaʻa haʻahaʻa haʻahaʻa, nui ka nui, pōkole ke ola lawelawe, nā pilikia, nā pilikia pollution he koʻikoʻi loa.

ʻO ka pilikia koʻikoʻi o ka hoʻohaumia ʻana i ka pākaukau lead-acid ʻaʻohe kaulahao ʻoihana pili. Pono e hoʻokomo i ke kaulahao ʻoihana pākaukau holoʻokoʻa i ka hana - hoʻohana - hana hou - hana hou, a ua hoʻomaʻamaʻa ʻia nā ʻāpana ʻōpala-acid i ka hoʻihoʻi ʻana i ka ʻōpala, ma ka ʻaoʻao hoʻokahi, no ka pilikia o nā hoʻopaʻapaʻa hoihoi, he ʻuʻuku loa nā ʻoihana ʻona ʻōpala. ma ka ʻaoʻao ʻē aʻe, nele nā ​​ʻoihana aupuni i nā ʻōnaehana hoʻoponopono kūikawā. ʻAʻole maikaʻi ka hana hoʻopōmaikaʻi, a e emi ana ka helu o ka hana hou ʻana, e hopena i ka pau ʻana o nā kumuwaiwai.

I kēia manawa, ʻoi aku ka liʻiliʻi o ka 40% o ke alakaʻi alakaʻi o koʻu ʻāina, a ua hiki i nā ʻāina kūkulu komohana i ka 70%. Pono ka ʻoihana kahiko i kona kumu ikaika, akā inā ʻaʻole maikaʻi kona pilikia kahiko e haʻalele, e mihi ia, no laila ʻaʻole ia he hui a ʻāina paha, e nānā hou aku i ka pākaukau lead-acid. hoʻoponopono ka pilikia haumia.
