01 - hōʻike ka lithium iron phosphate i ka piʻi ʻana

Loaʻa i ka pākaukau Lithium nā mea maikaʻi o ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka hoʻopiʻi wikiwiki a me ka lōʻihi. Hiki ke ʻike ʻia mai ka pākaukau kelepona paʻa lima a me ka pākaukau kaʻa. Ma waena o lākou, ʻelua mau lālā nui o ka pā lithium hao i kēia manawa.

No nā koi palekana, ma ke kahua o nā kaʻa kaʻa a me nā kaʻa hana kūikawā, ka lithium iron phosphate power battery me ka haʻahaʻa haʻahaʻa, ʻoi aku ka ʻoi aku o ka ʻenehana huahana palekana i hoʻohana ʻia ma kahi kiʻekiʻe. Hoʻohana nui ʻia ka pahu lithium ternary me ka ikehu kikoʻī kiʻekiʻe ma ke kahua o nā kaʻa kaʻa. I loko o kahi pūʻulu hoʻolaha hou, ua hoʻonui ʻia ka hapa o nā pākahi lithium iron phosphate ma ke kahua o nā kaʻa kaʻa mai lalo o 20% ma mua a hiki i kahi 30%.

ʻO Lithium iron phosphate (LiFePO4) kekahi o nā mea cathode maʻamau i hoʻohana ʻia no nā pākahi lithium-ion. Loaʻa iā ia ke kūpaʻa wela maikaʻi, ka liʻiliʻi o ka moisture absorption a me ka maikaʻi o ka hoʻokuʻu ʻana i ka hoʻoiho ma lalo o ke kūlana piha. ʻO ia ke kumu o ka noiʻi, hana a me ka hoʻomohala ʻana i ke kahua o ka mana a me ka mālama ʻana i ka ikehu lithium-ion. Eia nō naʻe, ma muli o ka palena o kona ʻano ponoʻī, ʻo ka pā lithium-ion me ka lithium iron phosphate e like me ka mea maikaʻi i ka conductivity maikaʻi ʻole, lohi diffusion rate o ka lithium ion, a me ka hoʻokuʻu maikaʻi ʻana i ka haʻahaʻa haʻahaʻa. ʻO kēia ka hopena i ka haʻahaʻa mile o nā kaʻa mua i hoʻolako ʻia me ka pākaukau lithium hao phosphate, ʻoi aku hoʻi i ke kūlana haʻahaʻa haʻahaʻa.

I mea e ʻimi ai i ka holomua o ka mileage endurance, ʻoi aku ka nui ma hope o ke kulekele kōkua o nā kaʻa ikehu hou e kau i nā koi kiʻekiʻe no ka mileage endurance kaʻa, ka ikaika o ka ikehu, ka hoʻohana ʻana i ka ikehu a me nā ʻano ʻē aʻe, ʻoiai ʻo ka lithium iron phosphate pākaukau e noho ana i ka mākeke ma mua, ka ternary lithium. ʻO ka pākaukau me ka nui o ka ikehu kiʻekiʻe ua lilo i kumu nui o ka mākeke kaʻa kaʻa kaʻa hou. Hiki ke ʻike ʻia mai ka hoʻolaha hou ʻana ʻoiai ʻo ka nui o ka pākaukau lithium iron phosphate i ke kahua o nā kaʻa kaʻa ua hoʻi hou ʻia, ʻo ka hapa o ka pākaukau lithium ternary ma kahi o 70%.

02 - ʻo ka palekana ka pōmaikaʻi nui loa

Hoʻohana maʻamau ka Nickel cobalt alumini a i ʻole nickel cobalt manganese e like me nā mea anode no nā pākahi lithium ternary, akā ʻo ka hana kiʻekiʻe o nā mea ʻaʻole lawe wale i ka ikehu kiʻekiʻe, akā lawe pū kekahi i nā pilikia palekana kiʻekiʻe. Hōʻike nā helu helu ʻole i ka makahiki 2019, ua ʻōlelo ʻia ka nui o nā ulia pōpilikia o nā kaʻa ikehu hou he 14 mau manawa ma mua o ka makahiki 2018, a ua hoʻopau ʻia nā hōʻailona e like me Tesla, Weilai, BAIC a me Weima.

Hiki ke ʻike ʻia mai ka pōʻino i ka nui o ke ahi i ke kaʻina hana, a i ʻole ma hope o ka hoʻouka ʻana, no ka mea e piʻi ka pākaukau i ka mahana i ka wā lōʻihi o ka hana. Ke ʻoi aku ka mahana o ka pākahi lithium ternary ma luna o 200 ° C, ua maʻalahi ka mea maikaʻi e decompose, a ke alakaʻi nei ka hopena oxidation i ka holo wikiwiki ʻana o ka wela a me ka puhi ʻino. ʻO ke ʻano olivine o ka lithium iron phosphate e lawe mai i ke kūpaʻa wela kiʻekiʻe, a ʻo kona holo ʻana a hiki i 800 ° C, a ʻoi aku ka liʻiliʻi o ka hana kinoea, no laila ʻoi aku ka palekana. ʻO ia ke kumu, e pili ana i ka noʻonoʻo palekana, hoʻohana maʻamau nā kaʻa kaʻa uila hou i nā pākahi lithium iron phosphate, ʻoiai ʻaʻole hiki i nā kaʻa uila hou e hoʻohana ana i nā pākahi lithium ternary ke komo i ka catalog o nā kaʻa ikehu hou no ka hoʻolaha ʻana a me ka noi.

I kēia mau lā, ua hoʻohana ʻelua mau kaʻa uila o Changan Auchan i ka pā lithium iron phosphate, ʻokoʻa ia mai nā ʻoihana kaʻa maʻamau e pili ana i nā kaʻa. ʻO nā hiʻohiʻona ʻelua o Changan Auchan he SUV a me MPV. Ua haʻi ʻo Xiong zewei, ka Hope Luna Nui o Changʻan Auchan Research Institute, i ka mea kākau moʻolelo: "ʻo kēia ka hōʻailona ua komo ʻo Auchan i ke au o ka mana uila ma hope o ʻelua mau makahiki o ka hoʻoikaika ʻana."

No ke kumu i hoʻohana ʻia ai ka pākaukau lithium iron phosphate, ua ʻōlelo ʻo Xiong ʻo ka palekana o nā kaʻa ikehu hou ʻo ia kekahi o nā "ʻeha ʻeha" o nā mea hoʻohana, a ʻo ka mea i hopohopo nui ʻia e nā ʻoihana. I ka noʻonoʻo ʻana i kēia, ua hoʻopau ka pahu pahu lithium hao phosphate i lawe ʻia e ke kaʻa hou i ka hoʻāʻo ʻana o ka hoʻāʻo ʻana ma luna o 1300 ° C lapalapa ahi, - 20 ° C haʻahaʻa haʻahaʻa kū, 3.5% paʻakai e kū ana, 11 kn hopena o waho, etc. ., a ua hoʻokō i ka "ʻehā makaʻu ʻole" palekana palekana palekana o "ʻaʻole makaʻu i ka wela, ʻaʻole makaʻu i ke anuanu, ʻaʻole makaʻu i ka wai, ʻaʻole makaʻu i ka hopena".

Wahi a nā hōʻike, ua hoʻolako ʻia ʻo Changan Auchan x7ev me ka mīkini paʻa paʻa synchronous me ka mana kiʻekiʻe o 150KW, me ka mile mile hoʻomanawanui ma mua o 405 km a me kahi pākaukau ola lōʻihi loa me 3000 mau manawa o ka cyclic charging. Ma ka mahana maʻamau, he hapalua hola wale nō e hoʻohui i ka mile mile hoʻomanawanui ma mua o 300 km. "ʻOiaʻiʻo, ma muli o ke ola ʻana o ka ʻōnaehana hoʻolaʻa ikehu braking, hiki i ka hoʻomanawanui o ke kaʻa ke hiki i kahi 420 km ma lalo o nā kūlana hana o ke kūlanakauhale." Ua hoʻohui ʻo Xiong.

Wahi a ka hoʻolālā hoʻomohala ʻenehana kaʻa hou (2021-2035) (Draft for comments) i hoʻopuka ʻia e ke Kuhina o ka ʻoihana a me ka ʻenehana ʻike, e kūʻai ʻia nā kaʻa kaʻa hou ma kahi o 25% e 2025. Hiki ke ʻike ʻia ka hapa o ka e hoʻonui mau ana nā kaʻa ikaika hou i ka wā e hiki mai ana. Ma kēia pōʻaiapili, e komo pū ana me Changʻan Automobile, nā ʻoihana kaʻa kūʻokoʻa kūʻokoʻa kūʻokoʻa e wikiwiki nei i ka hoʻolālā o ka mākeke kaʻa ikehu hou.
