01 - hōʻike ka lithium iron phosphate i kahi ʻano piʻi

ʻO ka liʻiliʻi o ka nui, ka māmā, ka hoʻouka wikiwiki a me ke kūpaʻa ka maikaʻi o ka pākahiko Lithium. Hiki ke ʻike ʻia mai nā pākahiko kelepona a me nā pākahiko kaʻa. I waena o lākou, ʻo ka pākahiko hao phosphate lithium a me ka pākahiko mea ternary ʻelua mau lālā nui o ka pākahiko lithium i kēia manawa.

No nā koi palekana, ma ke kahua o nā kaʻa ohua a me nā kaʻa kumu kūikawā, ua hoʻohana ʻia ka pākahiko mana lithium hao phosphate me ke kumukūʻai haʻahaʻa, ʻoi aku ka maikaʻi a me ka ʻenehana huahana palekana ma kahi uku kiʻekiʻe. Hoʻohana nui ʻia ka pākahiko lithium ternary me ka ikehu kikoʻī kiʻekiʻe ma ke kahua o nā kaʻa ohua. Ma kahi pūʻulu hou o nā hoʻolaha, ua piʻi ka hapa o nā pākahiko lithium hao phosphate ma ke kahua o nā kaʻa ohua mai ka liʻiliʻi ma mua o 20% a i kahi o 30%.

ʻO ka Lithium iron phosphate (LiFePO4) kekahi o nā mea cathode i hoʻohana pinepine ʻia no nā pila lithium-ion. Loaʻa iā ia ke kūpaʻa wela maikaʻi, emi ka omo ʻana o ka makū a me ka hana pōʻaiapuni hoʻokuʻu hoʻouka maikaʻi loa ma lalo o ke kūlana piha. ʻO ia ke kikowaena o ka noiʻi, ka hana ʻana a me ka hoʻomohala ʻana ma ke kahua o ka mana a me ka mālama ikehu o nā pila lithium-ion. Eia naʻe, ma muli o ka palena o kona ʻano ponoʻī, ʻo ka pila lithium-ion me ka lithium iron phosphate ma ke ʻano he mea maikaʻi he conductivity haʻahaʻa, lohi ka wikiwiki o ka diffusion o ka lithium ion, a maikaʻi ʻole ka hana hoʻokuʻu ʻana ma ka mahana haʻahaʻa. ʻO kēia ka hopena i ka mileage haʻahaʻa o nā kaʻa mua i lako me ka pila lithium iron phosphate, ʻoi aku hoʻi i ke kūlana mahana haʻahaʻa.

I mea e ʻimi ai i ka holomua o ka mileage hoʻomanawanui, ʻoi aku hoʻi ma hope o ke kulekele kākoʻo o nā kaʻa ikehu hou i hoʻokau i nā koi kiʻekiʻe no ka mileage hoʻomanawanui o ke kaʻa, ka nui o ka ikehu, ka hoʻohana ʻana i ka ikehu a me nā ʻano ʻē aʻe, ʻoiai ua noho mua ka pākahi lithium iron phosphate i ka mākeke, ua lilo mālie ka pākahi lithium ternary me ka nui o ka ikehu i mea nui o ka mākeke kaʻa ohua ikehu hou. Hiki ke ʻike ʻia mai ka hoʻolaha hou loa ʻoiai ua hoʻihoʻi hou ʻia ka hapa o ka pākahi lithium iron phosphate ma ke kahua o nā kaʻa ohua, aia nō ka hapa o ka pākahi lithium ternary ma kahi o 70%.

02 - ʻo ka palekana ka pōmaikaʻi nui loa

Hoʻohana nui ʻia ka nickel cobalt alumini a i ʻole ka nickel cobalt manganese ma ke ʻano he mea anode no nā pila lithium ternary, akā ʻo ka hana kiʻekiʻe o nā mea ʻaʻole wale e lawe mai i ka nui o ka ikehu, akā lawe mai hoʻi i nā pilikia palekana kiʻekiʻe. Hōʻike nā helu helu piha ʻole i ka makahiki 2019, ua ʻōlelo ʻia ka nui o nā ulia hoʻā ponoʻī o nā kaʻa ikehu hou he 14 mau manawa ma mua o ka makahiki 2018, a ua hoʻopuka mau nā lama e like me Tesla, Weilai, BAIC a me Weima i nā ulia hoʻā ponoʻī.

Hiki ke ʻike ʻia mai ka ulia pōpilikia ke ahi nui i ke kaʻina hana hoʻouka, a i ʻole ma hope koke iho o ka hoʻouka ʻana, no ka mea e piʻi ka mahana o ka pila i ka wā hana lōʻihi. Ke ʻoi aku ka mahana o ka pila lithium ternary ma mua o 200 ° C, maʻalahi ka palaho ʻana o ka mea maikaʻi, a alakaʻi ka hopena oxidation i ka holo wikiwiki ʻana o ka thermal a me ka puhi ʻana. ʻO ke ʻano olivine o ka lithium iron phosphate e lawe mai i ke kūpaʻa o ka mahana kiʻekiʻe, a hiki i kona mahana holo i 800 ° C, a emi iho ka hana kinoea, no laila ʻoi aku ka palekana. ʻO ia ke kumu, ma muli o nā noʻonoʻo palekana, hoʻohana pinepine nā kaʻa ikehu hou i nā pila lithium iron phosphate, ʻoiai ʻaʻole hiki i nā kaʻa ikehu hou e hoʻohana ana i nā pila lithium ternary ke komo i ka papa inoa o nā kaʻa ikehu hou no ka hoʻolaha a me ka noi.

I kēia mau lā iho nei, ua hoʻohana ʻelua mau kaʻa uila o Changan Auchan i ka pākahiko lithium hao phosphate, kahi ʻokoʻa mai nā ʻoihana kaʻa maʻamau e kālele ana i nā kaʻa. ʻO nā hiʻohiʻona ʻelua o Changan Auchan he SUV a me MPV. Ua haʻi aku ʻo Xiong zewei, ka hope luna nui o ka Chang'an Auchan Research Institute, i ka mea kākau moʻolelo: "hōʻailona kēia ua komo kūhelu ʻo Auchan i ke au o ka mana uila ma hope o ʻelua mau makahiki o ka hoʻoikaika ʻana."

No ke kumu e hoʻohana ʻia ai ka pākahiko lithium hao phosphate, ua ʻōlelo ʻo Xiong ʻo ka palekana o nā kaʻa ikehu hou kekahi o nā "kiko ʻeha" o nā mea hoʻohana, a ʻo ia hoʻi ka mea e hopohopo nui ʻia e nā ʻoihana. I ka noʻonoʻo ʻana i kēia, ua hoʻopau ka pūʻolo pākahiko lithium hao phosphate i lawe ʻia e ke kaʻa hou i ka hoʻāʻo palena o ka hoʻomoʻa ʻana ma luna o 1300 ° C, - 20 ° C ke kū ʻana o ka mahana haʻahaʻa, 3.5% ka paʻakai paʻakai e kū ana, 11 kn ka hopena o ke kaomi waho, a pēlā aku, a ua hoʻokō i ka hopena palekana pākahiko "ʻehā makaʻu ʻole" o "ʻaʻole makaʻu i ka wela, ʻaʻole makaʻu i ke anu, ʻaʻole makaʻu i ka wai, ʻaʻole makaʻu i ka hopena".

Wahi a nā hōʻike, ua lako ʻia ʻo Changan Auchan x7ev me kahi motika synchronous magnet mau loa me ka mana kiʻekiʻe loa o 150KW, me ka mileage hoʻomanawanui o ʻoi aku ma mua o 405 km a me kahi pākahiko ola lōʻihi loa me 3000 mau manawa o ka hoʻouka cyclic. Ma ka mahana maʻamau, he hapalua hola wale nō e hoʻohui i ka mileage hoʻomanawanui o ʻoi aku ma mua o 300 km. "ʻO kaʻoiaʻiʻo, ma muli o ke ola ʻana o ka ʻōnaehana hoʻōla ikehu braking, hiki i ke ahonui o ke kaʻa ke hiki i kahi 420 km ma lalo o nā kūlana hana kūlanakauhale." Ua hoʻohui ʻo Xiong.

Wahi a ka hoʻolālā hoʻomohala ʻoihana kaʻa ikehu hou (2021-2035) (Kōkuhi no nā manaʻo) i hoʻopuka ʻia e ke Kuhina o ka ʻoihana a me ka ʻenehana ʻike, e helu ana ke kūʻai aku ʻana o nā kaʻa ikehu hou ma kahi o 25% ma ka makahiki 2025. Hiki ke ʻike ʻia e hoʻomau ka piʻi ʻana o ka hapa o nā kaʻa ikehu hou i ka wā e hiki mai ana. Ma kēia ʻano, me Chang'an Automobile, ke hoʻolalelale nei nā ʻoihana kaʻa kūʻokoʻa kuʻuna i ka hoʻonohonoho ʻana o ka mākeke kaʻa ikehu hou.
