He ahahao lithiumpākaukau?Hoʻomaka i ke kumu hana a me nā pono o ka pā hao lithium

ʻO ka pā hao hao he ʻano pākaukau ma ka ʻohana pākaukau lithium.ʻO kona inoa piha ka lithium iron phosphate lithium ion battery.ʻO ka mea cathode ka nui o ka lithium iron phosphate.No ka mea kūpono loa kāna hana no nā noi mana, ua kapa ʻia ʻo ia ʻo "lithium iron power battery".(i kapa ʻia ma hope aku ʻo "lithium iron battery")

ʻO ke kumu hana o ka pā hao lithium (LiFePO4)
ʻO ke ʻano o loko o ka pākaukau LiFePO4: ʻO ka LiFePO4 me ke ʻano olivine ma ka ʻaoʻao hema ke hoʻohana ʻia ma ke ʻano he pou maikaʻi o ka pākaukau, i hoʻopili ʻia e ka pahu alumini a me ka pou kūpono o ka pā.Aia ma waenakonu he diaphragm polymer, kahi e hoʻokaʻawale ai i ka pou maikaʻi mai ka pou maikaʻi ʻole.Eia nō naʻe, hiki i ka lithium ion Li+ ke hele ma o ka uila e - ʻaʻole hiki.Aia ma ka ʻaoʻao ʻākau ka pou ʻino o ka pākaukau i haku ʻia me ke kalapona (graphite), i hoʻopili ʻia e ka pahu keleawe a me ka pou ʻino o ka pā.Aia ka electrolyte o ka pākaukau ma waena o nā ʻaoʻao o luna a me lalo o ka pākaukau, a ua hoʻopaʻa ʻia ka pākaukau e kahi pūpū metala.

Ke hoʻopiʻi ʻia ka pākaukau LiFePO4, e neʻe ka lithium ion Li + i ka electrode maikaʻi i ka electrode maikaʻi ʻole ma o ka membrane polymer;I ka wā o ka hoʻokuʻu ʻana, neʻe ka lithium ion Li+ i ka electrode maikaʻi i ka electrode maikaʻi ma o ka diaphragm.Kapa ʻia ka pākaukau Lithium-ion ma hope o ka neʻe ʻana o nā ion lithium i ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana.

ʻO ka hana nui o ka pākaukau LiFePO4
ʻO ka voltage nominal o ka pākaukau LiFePO4 he 3.2 V, ʻo 3.6 V ka volta hoʻopau hope, a ʻo 2.0 V ka hopena o ka hoʻokuʻu ʻana. e ʻano ʻokoʻa.No ka laʻana, ʻokoʻa loa ka mana o ka pākaukau o ke ʻano hoʻokahi (pākaukau maʻamau i loko o ka pūʻolo hoʻokahi) (10%~20%).

Pono opākahi hao lithium
Ke hoʻohālikelikeʻia me nā'ōmole lead-acid maʻamau, loaʻa i nā pākahi lithium-ion nā pōmaikaʻi nui i ka hana voltage, ka nui o ka ikehu, ke ola pōʻai, a me nā mea'ē aʻe. hana wela kiʻekiʻe, puka mana kiʻekiʻe, ola pōʻai lōʻihi, paona māmā, mālama i ke kumukūʻai hoʻoikaika lumi mīkini, liʻiliʻi liʻiliʻi, lōʻihi ke ola pākaukau, palekana maikaʻi, etc.
