01 – e whakaatu ana te phosphate rino lithium i te ia pikinga

He iti te rahi, he māmā te taumaha, he tere te utu, ā, he roa te mau o ngā painga o te pākahiko lithium. Ka kitea tēnei i roto i ngā pākahiko waea pūkoro me ngā pākahiko motuka. I roto i ēnei, ko te pākahiko lithium rino phosphate me te pākahiko rauemi tuatoru ngā peka matua e rua o te pākahiko lithium i tēnei wā.

Mō ngā whakaritenga haumaru, i roto i te mara o ngā waka pāhihi me ngā waka kaupapa motuhake, kua whakamahia te pākahiko mana lithium rino phosphate me te utu iti ake, he hangarau hua pakari ake, he haumaru ake hoki i te tere teitei ake. Ko te pākahiko lithium ternary me te kaha motuhake teitei ake e whakamahia whānuitia ana i roto i te mara o ngā waka pāhihi. I roto i tētahi puranga hou o ngā panuitanga, kua piki ake te ōwehenga o ngā pākahiko lithium rino phosphate i roto i te mara o ngā waka pāhihi mai i raro iho i te 20% i mua ki te 30%.

Ko te phosphate rino lithium (LiFePO4) tētahi o ngā rauemi katote e whakamahia whānuitia ana mō ngā pākahiko lithium-ion. He pai te pumau o te wera, he iti ake te mimiti makuku, ā, he pai rawa te mahi huringa tuku utu i raro i te āhua kua utua katoatia. Koinei te arotahi o te rangahau, te whakaputa me te whanaketanga i roto i te mara o ngā pākahiko lithium-ion rokiroki hiko me te pūngao. Heoi, nā te iti o tōna hanganga ake, he ngoikore te kawe hiko o te pākahiko lithium-ion me te phosphate rino lithium hei rauemi pai, he puhoi te tere horapa o te phosphate lithium, ā, he ngoikore te mahi tuku i te pāmahana iti. Ko te hua o tēnei he iti te maero o ngā waka o mua i whakauruhia ki te pākahiko phosphate rino lithium, inā koa i roto i te āhua pāmahana iti.

Hei rapu i te putanga hou o te maero manawanui, inā koa i muri i te kaupapa here tautoko mō ngā waka hiko hou kua whakatakotohia he whakaritenga teitei ake mō te maero manawanui o te waka, te kiato o te kaha, te whakapaunga kaha me ētahi atu āhuatanga, ahakoa kua nohoia e te pākahiko phosphate rino lithium te mākete i mua, kua piki haere te pākahiko lithium ternary me te kiato kaha teitei ake hei matua o te mākete waka pāhihi hiko hou. Ka kitea mai i te panuitanga hou ahakoa kua hoki mai te ōwehenga o te pākahiko phosphate rino lithium i roto i te mara o ngā waka pāhihi, kei te 70% tonu te ōwehenga o te pākahiko lithium ternary.

02 – ko te haumaru te painga nui rawa atu

Ko te nikara konumohe, te nikara konumohe rānei, e whakamahia whānuitia ana hei rauemi anode mō ngā pākahiko lithium toru, engari ko te kaha o ngā rauemi ehara i te mea he nui te kaha o te pūngao, engari he nui hoki ngā tūponotanga haumaru. E whakaatu ana ngā tatauranga kāore i oti i te whakaoti, i te tau 2019, ko te maha o ngā aituā mura-ā-koe o ngā waka hiko hou i whakahuatia 14 ngā wā neke atu i tērā i te tau 2018, ā, kua puta ake ngā aituā mura-ā-koe a ngā waitohu pēnei i a Tesla, Weilai, BAIC me Weima.

Ka kitea i roto i te aituā ko te nuinga o te ahi ka puta i te tukanga utu, i muri tata mai rānei i te utunga, nā te mea ka piki te pāmahana o te pākahiko i te wā e whakamahia ana mō te wā roa. Ina neke atu i te 200°C te pāmahana o te pākahiko lithium toru, ka ngawari te pirau o te rauemi pai, ā, ka tere te rere o te wera me te mura kino i te tauhohenga waikura. Ka hua mai i te hanganga olivine o te lithium rino phosphate te pumau o te pāmahana, ā, ka eke tōna pāmahana rere ki te 800°C, ā, he iti ake te whakaputanga hau, nō reira he haumaru ake. Koinei anō te take, i runga i ngā whakaaro haumaru, ka whakamahia e ngā pahi hiko hou ngā pākahiko lithium rino phosphate, ko ngā pahi hiko hou e whakamahi ana i ngā pākahiko lithium toru kāore e taea te whakauru ki te rārangi o ngā waka hiko hou mō te whakatairanga me te tono mō te wā poto.

Nō nā tata nei, e rua ngā waka hiko o Changan Auchan kua whakamahi i te pākahiko lithium rino phosphate, he rerekē tēnei i ngā umanga waka whānui e aro ana ki ngā motuka. Ko ngā tauira e rua o Changan Auchan ko te SUV me te MPV. I kī atu a Xiong zewei, te kaiwhakahaere matua tuarua o te Chang'an Auchan Research Institute, ki te kairīpoata: "he tohu tēnei kua uru mana a Auchan ki te ao hiko i muri i ngā tau e rua o ngā mahi."

Mō te take e whakamahia ai te pākahiko lithium rino phosphate, i kī a Xiong ko te haumaru o ngā waka hiko hou tētahi o ngā "wāhi mamae" o ngā kaiwhakamahi, ā, ko te mea tino āwangawanga hoki o ngā umanga. Hei whakaaro ki tēnei, kua oti i te kete pākahiko lithium rino phosphate e mau ana i te motuka hou te whakamātautau rohe o te tunu mura neke atu i te 1300 ° C, te tū i te pāmahana iti - 20 ° C, te tū i te otinga tote 3.5%, te pānga pēhanga o waho 11 kn, me ētahi atu, ā, kua tutuki i a ia te otinga haumaru pākahiko "whā kāore e wehi" o te "kāore e wehi i te wera, kāore e wehi i te makariri, kāore e wehi i te wai, kāore e wehi i te pānga".

E ai ki ngā pūrongo, kei te Changan Auchan x7ev he motuka tukutahi aukume tuturu me te mana mōrahi o te 150KW, me te maero manawanui neke atu i te 405 km me te pākahiko tino roa me te 3000 ngā wā o te utunga huringa. I te pāmahana noa, e hawhe haora noa iho te roa hei tāpiri i te maero manawanui neke atu i te 300 km. "Inaa, nā te noho o te pūnaha whakaora pūngao aukati, ka taea e te manawanui o te waka te eke ki te 420 km i raro i ngā āhuatanga mahi tāone." tā Xiong tāpiri.

E ai ki te mahere whanaketanga o te umanga waka pūngao hou (2021-2035) (Tauira mō ngā kōrero) i tukuna e te Manatū Ahumahi me te Hangarau Pārongo, ka eke te hokonga o ngā waka pūngao hou ki te 25% i te tau 2025. Ka kitea ko te ōwehenga o ngā waka pūngao hou ka piki haere tonu i te heke mai. I roto i tēnei horopaki, tae atu ki a Chang'an Automobile, kei te tere haere ngā umanga waka waitohu motuhake tuku iho i te whakatakotoranga o te mākete waka pūngao hou.
