ʻenehana, Pōmaikaʻi, a me nā kumukūʻai o nā Bateri Lithium-ion

Pehea e hana ai ka pākaukau lithium-ion? He aha nā mea maikaʻi i loaʻa iā ia ma mua o kahi pākaukau lead-acid? I ka manawa hea e uku ʻia ai kahi waihona pākaukau lithium-ion?A pākaukau lithium-ion(pōkole: lithiumion battery a i ʻole Li-ion battery) ʻo ia ka huaʻōlelo maʻamau no nā accumulators e pili ana i nā pūhui lithium i nā ʻāpana ʻekolu, i ka electrode maikaʻi ʻole, i ka electrode maikaʻi a me ka electrolyte, ka cell electrochemical. He kiʻekiʻe ka ikehu koʻikoʻi ka lithium-ion i hoʻohālikelike ʻia me nā ʻano ʻokoʻa ʻē aʻe, akā makemake i nā kaapuni pale uila i ka hapa nui o nā noi, no ka mea, ʻoi aku ka maikaʻi o ka hoʻokuʻu ʻana a me ka hoʻonui ʻana.Hoʻopiʻi ʻia nā pākahi solar lithium i ka uila mai ka ʻōnaehana photovoltaic a hoʻokuʻu hou ʻia e like me ka mea e pono ai. No ka manawa lōʻihi, ua manaʻo ʻia ʻo nā pākahi alakaʻi i ka hopena mana o ka lā no kēia kumu. Eia nō naʻe, e pili ana i nā pākaukau lithium-ion he mau mea maikaʻi loa, ʻoiai ke pili mau nei ke kūʻai ʻana me nā kumukūʻai hou aku, akā naʻe, hoʻihoʻi ʻia ma o ka hoʻohana ʻana.Hoʻolālā ʻenehana a me ke ʻano o ka mālama ʻana i ka ikehu o nā Bateri Lithium-ion'A'ole 'oko'a ka 'oko'a o nā 'akika Lithium-ion mai nā 'akika lead-acid i kā lākou hana ma'amau. ʻOkoʻa wale nō ka mea lawe ukana: Ke hoʻopiʻi ʻia ka pākaukau, "neʻe" nā ion lithium mai ka electrode maikaʻi i ka electrode maikaʻi ʻole o ka pākaukau a noho "mālama ʻia" ma laila a hiki i ka hoʻokuʻu hou ʻana o ka pā. Hoʻohana mau ʻia nā conductors graphite kiʻekiʻe e like me nā electrodes. Eia nō naʻe, aia nā ʻano like ʻole me nā conductors hao a i ʻole nā ​​​​conductors cobalt.Ma muli o nā conductors i hoʻohana ʻia, e loaʻa i nā pākahi lithium-ion nā ʻokoʻa uila. Pono ka electrolyte pono'ī me ka wai ʻole i loko o kahi pākaukau lithium-ion no ka mea ʻo ka lithium a me ka wai e hoʻoulu ai i kahi hopena ʻino. I ka hoʻohālikelike ʻana i kā lākou mau mea alakaʻi-acid mua, ʻaʻohe (kokoke) ʻaʻohe hopena hoʻomanaʻo a i ʻole ka hoʻokuʻu ponoʻī ʻana o nā pā lithium-ion hou, a paʻa nā pā lithium-ion i ko lākou mana piha no ka manawa lōʻihi.ʻO nā pākaʻi mālama mana lithium-ion ka mea maʻamau i nā mea kemika manganese, nickel a me ka cobalt. ʻO ka Cobalt (huaʻōlelo kemikala: cobalt) he mea laha ʻole a no laila e ʻoi aku ka pipiʻi o ka hana ʻana o nā pākaukau Li. Eia kekahi, he pōʻino ka cobalt i ke kaiapuni. No laila, nui nā noiʻi noiʻi e hana i nā mea cathode no nā ʻeke kiʻekiʻe-voltage lithium-ion me ka ʻole o ka cobalt.Nā Pōmaikaʻi o nā Bateri Lithium-ion Ma mua o nā Bateri Lead-acid◎ʻO ka hoʻohana ʻana i nā pākahi lithium-ion hou e lawe pū me ia i nā mea maikaʻi ʻole i hiki ʻole i nā pākī lead-acid maʻalahi ke hāʻawi.◎ʻO ka mea hoʻokahi, ʻoi aku ka lōʻihi o ka lawelawe ʻana ma mua o nā pākaukau lead-acid. Hiki i kahi pākahi lithium-ion ke mālama i ka mana o ka lā no kahi manawa kokoke i 20 mau makahiki.◎ʻOi aku ka nui o ka nui o nā pōʻai hoʻoili a me ka hohonu o ka hoʻokuʻu ʻana ma mua o nā pākahi alakaʻi.◎Ma muli o nā ʻano mea like ʻole i hoʻohana ʻia i ka hana ʻana, ʻoi aku ka māmā o nā pākahi lithium-ion ma mua o nā pā alakaʻi a ʻoi aku ka paʻakikī. No laila, liʻiliʻi lākou i ka manawa i ka wā e hoʻokomo ai.◎ʻOi aku ka maikaʻi o ka mālama ʻana i nā ʻāpana lithium-ion ma ke ʻano o ka hoʻokuʻu ʻana iā ia iho.◎Eia kekahi, ʻaʻole pono e poina i ka ʻaoʻao kaiapuni: No ka mea, ʻaʻole maikaʻi loa nā pihi alakaʻi i kā lākou hana ʻana ma muli o ke alakaʻi i hoʻohana ʻia.Nā Kiʻi Kiʻi ʻenehana o nā Bateri Lithium-ionMa ka ʻaoʻao ʻē aʻe, pono e haʻi ʻia, ma muli o ka lōʻihi o ka hoʻohana ʻana i nā pākaukau alakaʻi, ʻoi aku ka nui o nā haʻawina lōʻihi lōʻihi ma mua o nā pā lithium-ion hou loa, no laila ko lākou hoʻohana ʻana a me nā koina pili. hiki ke helu maikaʻi a ʻoi aku ka hilinaʻi. Eia kekahi, ʻoi aku ka maikaʻi o ka ʻōnaehana palekana o nā pākahi alakaʻi hou ma mua o nā pā lithium-ion.Ma ke kumu, ʻaʻole kumu ʻole ka hopohopo e pili ana i nā pōʻino pōʻino i loko o nā cell li ion: No ka laʻana, hiki ke hana ʻia nā dendrites, ʻo ia hoʻi nā waihona lithium kikoʻī, ma ka anode. ʻO ka manaʻo o kēia mau mea e hoʻomaka i nā kaapuni pōkole, a no laila ke kumu hoʻi i ka holo ʻana o ka wela (he hopena exothermic me ka hoʻoulu ʻana i ka wela ikaika a hoʻoikaika ponoʻī), hāʻawi ʻia i loko o nā cell lithium i loaʻa nā ʻāpana cell haʻahaʻa. I ka hihia maikaʻi loa, hiki i ka hoʻolaha ʻana o kēia hewa i nā kelepona pili ke alakaʻi i kahi hopena kaulahao a me ke ahi i loko o ka pākaukau.Eia nō naʻe, ʻoiai ʻoi aku ka nui o nā mea kūʻai aku e hoʻohana ana i nā pā lithium-ion e like me nā ʻona solar, ʻo nā hopena aʻo o nā mea hana me ka nui o ka hana nui e alakaʻi i ka hoʻomaikaʻi ʻana i ka ʻenehana o ka mālama ʻana a me ka palekana o ka hana o nā pā lithium-ion a me nā hōʻemi hou aʻe. . Hiki ke hōʻuluʻulu ʻia ke kūlana hoʻomohala ʻenehana i kēia manawa o nā pā Li-ion i nā kiʻi koʻikoʻi ʻenehana:

ʻO ka hiki ke mālama a me nā kumukūʻai o nā Bateri Solar Lithium-ionʻOi aku ka kiʻekiʻe o ke kumu kūʻai o kahi pākahiko lithium-ion solar ma mua o ke kumu kūʻai o kahi pākika lead-acid. No ka laʻana, ʻo nā pākahi kepau me ka mana o5 kWhi kēia manawa he awelika o 800 kālā no ka hola kilowatt o ka mana nominal.ʻO nā ʻōnaehana lithium hoʻohālikelike, ma ka ʻaoʻao ʻē aʻe, he 1,700 kālā no ka hola kilowatt. Eia naʻe, ʻoi aku ka kiʻekiʻe o ka hoʻolaha ʻana ma waena o nā ʻōnaehana ʻoi aku ka liʻiliʻi a me ka pipiʻi ma mua o nā ʻōnaehana alakaʻi. No ka laʻana, loaʻa pū nā pā lithium me 5 kWh no ka liʻiliʻi o 1,200 kālā no kWh.ʻOiai ke kiʻekiʻe o nā kumukūʻai kūʻai maʻamau, ʻoi aku ka maikaʻi o ke kumukūʻai o kahi ʻōnaehana solar lithium-ion i kēlā me kēia hola kilowatt i mālama ʻia ma luna o ke ola holoʻokoʻa holoʻokoʻa, no ka mea, hāʻawi nā pā lithium-ion i ka mana no ka lōʻihi ma mua o nā pākiʻi lead-acid. e pani ʻia ma hope o kekahi manawa.No laila, i ke kūʻai ʻana i kahi ʻōnaehana mālama pākaukau hale, ʻaʻole pono e makaʻu kekahi i nā kumukūʻai kūʻai kiʻekiʻe, akā pono e hoʻopili mau i ka pono o ka hoʻokele waiwai o ka pā lithium-ion i ke ola lawelawe holoʻokoʻa a me ka helu o nā hola kilowatt i mālama ʻia.Hiki ke hoʻohana ʻia nā ʻōkuhi ma lalo nei no ka helu ʻana i nā kiʻi koʻikoʻi a pau o kahi ʻōnaehana mālama pākaukau lithium-ion no nā ʻōnaehana PV:1) Kapa inoa inoa * nā kaʻina hoʻoili = Theoretical storage capacity.2) Hiki ke hoʻopaʻa ʻia ka manaʻo o ka manaʻo * ʻO ka maikaʻi * Ka hohonu o ka hoʻokuʻu ʻana = Hiki ke hoʻohana ʻia ka hiki ke mālama3) Ke kumukūʻai kūʻai / hiki ke hoʻohana i ka hiki ke mālama = Ke kumu kūʻai no ka kWh i mālama ʻia

BSLBATT: Mea hana i nā ʻōhua Lithium-ion SolarI kēia manawa he nui nā mea hana a me nā mea hoʻolako i nā pā lithium-ion.BSLBATT Lithium-ion nā pila lāE hoʻohana i nā pūnaewele LiFePo4 A-grade mai BYD, Nintec, a me CATL, e hoʻohui iā lākou, a hāʻawi iā lākou i kahi ʻōnaehana hoʻokele uku (pūnaewele hoʻokele pila) i hoʻololi ʻia i ka mālama mana photovoltaic e hōʻoia i ka hana kūpono a me ka pilikia ʻole o kēlā me kēia keena mālama. e like me ka ʻōnaehana holoʻokoʻa.
