Lithium iron phosphate e like me kekahi o nā ʻano pākaukau o kēia manawa o nā kaʻa uila, i ʻike ʻia e kona kūpaʻa paʻa wela, ʻaʻole kiʻekiʻe nā kumukūʻai hana, lōʻihi ke ola o ka lawelawe, a me nā mea ʻē aʻe. ʻoi aku ka liʻiliʻi o 10 degere, ʻoiai hiki ke hoʻohana maʻamau ka pākaukau, akā e hoʻemi nui ʻia ka pono o ka hoʻouka ʻana.
No ka hoʻoilo lithium hao phosphate he ʻino loa kēia ʻōlelo, ʻoiaʻiʻo, ʻoi aku ka nui o ka hoʻoilo haʻahaʻa haʻahaʻa lithium iron phosphate ma mua o ka pohō o ka pā lithium ternary, akā ʻaʻole nui. Ma lalo o nā kūlana like, inā e emi ana ka kaʻa me nā ʻeke lithium ternary i ka 25% ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa o ka hoʻoilo, aʻo ka lithium iron phosphate e hiki i 30%. ʻO ka ʻokoʻa ma waena o nā mea ʻelua ʻo ia wale nō, ʻaʻole i like ka nui e like me ka lua i haʻi ʻia e kekahi poʻe ma ka pūnaewele. Eia kekahi, ʻaʻole i hoʻoholo holoʻokoʻa ʻia ke āpau e nā waiwai innate o ka pākaukau.
ʻO ka ʻokoʻa ma waena o ka lithium iron phosphate a me ka hoʻohālikelike pākahi lithium ternary
ʻO ka nui o ka ikehu o ka pākaukau he helu kuhikuhi e pili ana i ka hana o nā kaʻa ikehu hou. He 110Wh/kg wale nō ka nui o ka ikehu o ka pā uila lithium iron phosphate, ʻoiai ʻo 200Wh/kg ka nui o ka ikehu o ka pahu lithium. ʻo ia hoʻi, ʻo ke kaumaha like o ka pākaukau, ʻo 1.7 ka nui o ka ikehu o ka pahu lithium iron phosphate, hiki ke lawe i kahi lōʻihi lōʻihi no nā kaʻa ikehu hou.
ʻO ka pākaukau Lithium iron phosphate i kēia manawa ke kūpaʻa wela maikaʻi loa o ka pā mana, ma ke ʻano o ka palekana i hoʻohālikelike ʻia i nā pākahi lithium ternary loaʻa nā pōmaikaʻi. Lithium iron phosphate battery electrothermal peak a hiki i ka 350 ℃, pono ka hoʻokumu ʻana o ke kino o ka pākaukau i 500 ~ 600 ℃ ma mua o ka hoʻomaka ʻana e decompose; ʻOiai ʻo ka paʻa wela o ka hana ʻana o ka pā lithium ternary he mea maʻamau, e hoʻomaka ana e decompose ma kahi o 300 ℃. ʻO ka lithium hao phosphate i kēia manawa ke kūpaʻa wela maikaʻi loa o ka pā uila mana, ma ke ʻano o ka palekana i hoʻohālikelike ʻia i nā pākahi lithium ternary loaʻa nā pono kūpono. . Lithium iron phosphate battery electrothermal peak a hiki i ka 350 ℃, pono ka hoʻokumu ʻana o ke kino o ka pākaukau i 500 ~ 600 ℃ ma mua o ka hoʻomaka ʻana e decompose; ʻOiai ʻo ka paʻa wela o ka hana ʻana o ka pā lithium ternary he mea maʻamau, e hoʻomaka ana e decompose ma kahi o 300 ℃. ʻO ka lithium hao phosphate i kēia manawa ke kūpaʻa wela maikaʻi loa o ka pā uila mana, ma ke ʻano o ka palekana i hoʻohālikelike ʻia i nā pākahi lithium ternary loaʻa nā pono kūpono. . Lithium iron phosphate battery electrothermal peak a hiki i ka 350 ℃, pono ka hoʻokumu ʻana o ke kino o ka pākaukau i 500 ~ 600 ℃ ma mua o ka hoʻomaka ʻana e decompose; ʻOiai ʻo ka paʻa wela o ka hana ʻana o ka pā lithium ternary he mea maʻamau, e hoʻomaka ana e decompose ma kahi o 300 ℃. ʻO ka lithium hao phosphate i kēia manawa ke kūpaʻa wela maikaʻi loa o ka pā uila mana, ma ke ʻano o ka palekana i hoʻohālikelike ʻia i nā pākahi lithium ternary loaʻa nā pono kūpono. . Lithium iron phosphate battery electrothermal peak a hiki i ka 350 ℃, pono ka hoʻokumu ʻana o ke kino o ka pākaukau i 500 ~ 600 ℃ ma mua o ka hoʻomaka ʻana e decompose; ʻOiai ʻo ke kūpaʻa wela o ka hana pākaukau lithium ternary he maʻamau loa, e hoʻomaka ana e decompose ma kahi o 300 ℃.
ʻOi aku ka maikaʻi o nā pākahi lithium Ternary. Hōʻike nā ʻikepili hoʻokolohua ʻaʻole nui ka ʻokoʻa ma waena o nā mea ʻelua i ka wā e hoʻopiʻi ana ma lalo o nā kūlana 10 ℃, akā ma luna o 10 ℃ e huki aku, i ka 20 ℃ e hoʻopiʻi ana, ʻo ka ratio mau o nā pākahi lithium ternary he 52.75%, ka ratio mau o ka lithium. ʻO ka phosphate hao he 10.08%, ʻo ka mua he 5 manawa o ka hope.
ʻOi aku ka maikaʻi o ke ola ʻana o ka pā uila lithium iron phosphate ma mua o ka pākahi lithium ternary, ʻo 2000 mau manawa ke ola ʻana o ka pākaukau lithium ternary, akā ma ke ʻano he 1000 cycles, hiki i ka 60%. ʻOiai inā ʻoi aku ka maikaʻi o ka ʻoihana Tesla, ma hope o nā manawa 3000 hiki ke mālama wale i ka 70% o ka mana, ʻoiai ʻo ka lithium iron phosphate pākaukau ma hope o ka pōʻai like, akā ʻo 80% o ka hiki.
I ka hoʻokaʻawale, lithium iron phosphate palekana pākaukau, ke ola lōʻihi, ke kūpaʻa wela kiʻekiʻe; ʻO ke kaumaha māmā o ka pahu lithium ternary, ka maikaʻi o ka hoʻouka ʻana, ke kūpaʻa haʻahaʻa haʻahaʻa. No laila, ʻo ka ʻokoʻa ma waena o nā mea ʻelua i hana ʻia e ka manawa a me kahi o ko lākou hiki ke hoʻololi i ke kumu o ka noho pū ʻana.
