He aha ka papa helu ʻana o nā kaʻa ikehu hou?

Ke lilo nei nā kaʻa uila ikehu hou i koho mua no nā poʻe he nui e kūʻai i nā kaʻa.ʻOi aku ka naʻauao a ʻoi aku ka maikaʻi ma mua o nā kaʻa wahie, akā he pilikia nui nā pila, e like me ke ola pākaukau, ka nui, ke kaumaha, ke kumu kūʻai a me ka palekana.ʻO kaʻoiaʻiʻo, he nui nā ʻano o nā pihi mana.I kēia lā, e kamaʻilio wau iā ʻoe e pili ana i nā ʻano ʻokoʻa o nā ʻokoʻa uila hou i loaʻa i kēia manawa.
No laila, ʻo nā pākahi mana o kēia manawa e loaʻa i nā ʻano like ʻole, ʻo ia hoʻi nā pākahi lithium ternary, nā ʻāpana lithium iron phosphate, nā ʻona lithium cobalt oxide, nā ʻāpana nickel metal hydride, a me nā ʻāpana aupuni paʻa.Ma waena o lākou, hoʻohana maʻamau nā trams ikehu hou i nā pākahi lithium ternary a me nā pā lithium hao phosphate, ʻo ia ka mea i kapa ʻia "ʻelua mau koa e hoʻokūkū nei no ka hegemony".

ʻO ka pahu lithium Ternary: ʻO ka mea maʻamau ka moʻo nickel-cobalt-manganese o CATL.Aia kekahi pūʻulu nickel-cobalt-aluminum i ka ʻoihana.Hoʻohui ʻia ʻo Nickel i ka pākaukau no ka hoʻonui ʻana i ka hiki ke mālama ʻia o ka pākaukau a hoʻomaikaʻi i ke ola pākaukau.
Hōʻike ʻia ʻo ia e ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka nui o ka ikehu kiʻekiʻe, e pili ana i 240Wh/kg, maikaʻi ʻole ka thermal stability, a ʻoi aku ka maʻalahi i nā pilikia hoʻopau ʻole.He kūpaʻa i ka wela haʻahaʻa akā ʻaʻole i ka wela kiʻekiʻe.ʻO ka palena haʻahaʻa o ka hoʻohana haʻahaʻa haʻahaʻa he emi 30 ° C, a hoʻemi ʻia ka mana ma kahi o 15% i ka hoʻoilo.Aia ma kahi o 200°C-300°C ka wela wela ma kahi o 200°C-300°C, a he kiʻekiʻe ka pilikia o ka puhi ʻana.

Lithium iron phosphate pākaukau: pili i ka lithium-ion pākahiko e hoʻohana ana i ka lithium iron phosphate ma ke ʻano he mea electrode maikaʻi a me ke kalapona e like me ka mea electrode maikaʻi ʻole.Hoʻohālikelike ʻia me nā pākahi lithium ternary, ʻoi aku ka maikaʻi o kona kūpaʻa wela a ʻoi aku ka haʻahaʻa o kāna kumukūʻai.Eia kekahi, ʻoi aku ka lōʻihi o ke ola pōʻaiapuni o nā pā lithium iron phosphate, ma ke ʻano he 3,500 mau manawa, ʻoiai ke hoʻomaka nei nā pā lithium ternary e pala ma kahi o 2,000 mau manawa o ka uku a me ka hoʻokuʻu.
Lithium cobalt oxide pākaukau: Lithium cobalt oxide pākahiko he lālā hoʻi ia o ka pākaukau lithium-ion.Loaʻa i nā ʻāpana lithium cobalt oxide ka hoʻolālā paʻa, ka lakene kiʻekiʻe a me ka hana piha.Eia nō naʻe, ʻaʻohe palekana a me ke kumukūʻai kiʻekiʻe o nā pā lithium cobalt oxide.Hoʻohana nui ʻia nā pākahiko lithium cobalt oxide no nā pākahi liʻiliʻi a me ka nui.He pākaukau maʻamau lākou i nā huahana uila a ʻaʻole hoʻohana ʻia i nā kaʻa.
Nickel-metal hydride battery: ʻO Nickel-metal hydride pālolo he ʻano hou o ka pākaukau ʻōmaʻomaʻo i hoʻomohala ʻia i nā makahiki 1990.Loaʻa iā ia nā hiʻohiʻona o ka ikehu kiʻekiʻe, ke ola lōʻihi, ʻaʻohe pollution.ʻO ka electrolyte o nā pākahi nickel-metal hydride he solution potassium hydroxide non-flammable, no laila inā hiki mai nā pilikia e like me ke kaapuni pōkole o ka pākaukau, ʻaʻole ia e hoʻopau i ka hoʻopau ʻana.Hoʻopaʻa ʻia ka palekana a ʻo ke kaʻina hana i oʻo.

Eia nō naʻe, ʻoi aku ka maʻalahi o ka hoʻopiʻi ʻana o nā pā nickel-metal hydride, ʻaʻole hiki ke hoʻohana i ka hoʻopiʻi wikiwiki wikiwiki, a ʻoi aku ka maikaʻi o kāna hana ma mua o nā pā lithium.No laila, ma hope o ka hoʻohana nui ʻia ʻana o nā pākahi lithium, hiki ke hoʻololi mālie ʻia nā pā nickel-metal hydride.
