ʻO ka pākahi lithium Ternary VS LiFePo4 pākaukau

ʻO ka pākaukau LiFePo4 e pili ana i ka pākaukau lithium ion me ka lithium iron phosphate ma ke ʻano he mea electrode maikaʻi a me ke kalapona e like me ka mea electrode maikaʻi ʻole.

ʻO ka pahu lithium Ternary e pili ana i ka pākaukau lithium e hoʻohana ana i ka lithium nickel-cobalt-manganate a i ʻole nickel-cobalt-aluminate lithium e like me ka mea electrode maikaʻi a me ka graphite e like me ka mea electrode maikaʻi ʻole.Kapa ʻia kēia ʻano pākaukau he "ternary" no ka mea ua hoʻoponopono ʻia ka paʻakai nickel, ka paʻakai cobalt a me ka paʻakai manganese i ʻekolu ʻāpana like ʻole.

Ua hoʻokuʻu hou ʻo Shenzhen Meind Technology Co., Ltd i kahi ikehu portablelako mana mālamame ka pahu lithium ternary i kūkulu ʻia, i kapa ʻia hoʻilako mana wahoa i ʻolehale mana lawe lima.Akā he nuinā kumu mana wahoma ka mākeke e hoʻohana ana i nā ʻōhua LiFePo4.No ke aha mākou e hoʻohana ai i ka pākahi lithium ternary?No ka mea, loaʻa nō hoʻi nā mea maikaʻi (e like me kēia) ma luna o nā pākahi LiFePo4.

1.Energy density

Ma keʻano laulā, hiki i ka ternary lithium battery ke mālama i ka mana hou aʻe i kēlā me kēia ʻāpana a i ʻole ke kaumaha, ma muli o nā ʻokoʻa o nā mea electrode ma waena o lākou.ʻO ka mea cathode o ka pākaukau LiFePo4 he lithium iron phosphate, a ʻo ka pahu lithium ternary he nickel cobalt manganese a i ʻole nickel cobalt alumina.ʻO ka ʻokoʻa o nā waiwai kemika e hoʻolilo i ka nui o ka ikehu o kahi pākahi lithium ternary o ka nui like 1.7 manawa o ka pā LiFePo4.

2.Low wela hana

ʻOi aku ka maikaʻi o ka hana ʻana o ka pākaukau LiFePo4 ma kahi haʻahaʻa haʻahaʻa ma mua o ka hana o ka pā lithium ternary.Aia ʻo LiFePo4 ma -10 ℃, hāʻule ka mana o ka pākaukau ma kahi o 50%, a ʻaʻole hiki i ka pākaukau ke hana ma mua o -20 ℃ i ka hapa nui.ʻO ka palena haʻahaʻa o ka lithium ternary he -30 ℃, a ʻoi aku ka liʻiliʻi o ke degere attenuation o ka lithium ternary ma mua o ka LiFePo4 ma ka mahana like.

3.Charging pono

Ma ke ʻano o ka hoʻopiʻi pono ʻana, ʻoi aku ka maikaʻi o ka bateria lithium ternary.Hōʻike ka ʻikepili hoʻokolohua he ʻokoʻa liʻiliʻi ma waena o nā pākaukau ʻelua i ka wā e hoʻopaʻa ana ma lalo o 10 ℃, akā e huki ʻia ka mamao ke kau ʻia ma luna o 10 ℃.I ka hoʻouka ʻana ma 20 ℃, ʻo 52.75% ka ratio mau o kēia manawa o ka pākahi lithium ternary, a ʻo ka pā LiFePo4 he 10.08%.ʻO ka mua he ʻelima manawa o ka hope.
