Ke hoʻolaha nui nei nā hui Kina iā lākou iho he mau mea hoʻomohala a me nā mea hana i nā pākaukau hoʻohiki. ʻAʻole kope wale ʻia nā ʻenehana ʻē aʻe, akā hoʻomaikaʻi ʻia a hoʻokō ʻia i kahi huahana kalepa.
ʻO ka hana kūleʻa o nā hui Kina e alakaʻi i ka holomua hiki ʻole i nā ʻano pākaukau, ʻoiai mākou, ʻoiaʻiʻo, makemake mākou i "nā mea āpau i ka manawa hoʻokahi." Akā ʻaʻole hiki kēia, akā ʻike koke ʻia kahi pākaukau me kahi ākea o 800 km a me ka ʻole o ka cobalt pipiʻi. Mahalo mākou i ka hui Kina SVOLT Energy Technology.
I kēia mau lā, ʻo ka hoʻokele ʻana o SVOLT Energy, kahi hui mua o ka mea hana kaʻa kaʻa Kina ʻo Great Wall Motor, kahi laina hou no ka hana ʻana i nā ʻōhua lithium-ion kaʻa. E hoʻopuka ka laina i ʻelua mau ʻano pākaukau, akā i kēia manawa i nā mea liʻiliʻi. E hoʻomaka ka hana nui i ka hapa ʻelua o ka makahiki aʻe. He aha kēia mau huahana?
Hoʻokahi ʻano pākaukau e hilinaʻi i nā pūnaewele 115 Ah me ka nui o ka ikehu o 245 Wh/kg. Hoʻolālā ʻia kēia mau cell e hoʻohana ʻia e hōʻuluʻulu i nā pākahi i hana nui ʻia no kahi ākea o nā kaʻa uila. ʻO ka huahana ʻelua, nā cell me ka mana o 226 Ah me ka ʻole cobalt, e hana wale ʻia no Great Wall Motor, e hoʻolālā ana e hoʻokomo iā lākou ma kāna mau kaʻa uila.
Wahi a ka mea hana, nā pūnaewele L6 lōʻihi hou i loko o ka pākaukau e hāʻawi i ka kaʻa uila me kahi ākea a hiki i 880 km ma ka uku hoʻokahi. ʻOi aku ke ola pākaukau i ʻōlelo ʻia ma mua o 15 mau makahiki, hiki ke hoʻololi ʻia i kahi ākea a hiki i 1,2 miliona km me ka ʻole o ka hoʻololi ʻana i ka pākaukau.
No ka hoʻokō ʻana i nā hiʻohiʻona puʻupuʻu kupanaha, ua hoʻomohala nā ʻenekini Kina i nā ʻenehana holoʻokoʻa a me nā kaʻina hana ʻenehana, e hoʻomaka me ka hoʻololi ʻana o ka cobalt i ka anode me ka nickel a me nā mea ʻē aʻe. No ka laʻana, hoʻololi ʻia nā ion lithium i loko o ka pākaukau e nā nickel ions, ka mea e pale ai i ka hoʻohaʻahaʻa ʻana o ka lithium i ka wā o ka hana ʻana. ʻO kēia ka mea i hoʻokumu i nā pilikia ʻenehana, i hoʻoholo maikaʻi ʻia i kēia manawa.
Nui nō hoʻi nā mea hou i ka hana ʻana i nā pūnaewele pākaukau, a me ka hoʻoponopono ʻana i ka hoʻolālā a me ka hana ʻana o ka pūʻulu pākahi pākahi multi-cell. Hoʻokumu ʻia ka pā pākaukau hou e like me ke kumu matrix a hiki ke maʻalahi ʻia i nā ʻāpana kikoʻī, e hōʻemi ana hoʻi i ke kumukūʻai o ka hana ʻana i nā hui pākaukau.
E hoʻohui pū kākou i ka hana ʻana o nā pākahiko SVOLT Energy me ka ʻole o ka cobalt ma kahi voli kiʻekiʻe aʻe - 4,3–4,35 V. ʻO ia ke kumu i ʻoi aku ka kiʻekiʻe o kā lākou ikehu i mālama ʻia ma mua o nā pākahi lithium-ion kuʻuna. E ʻike ʻia ke ʻano o kā lākou hana ma ka hana.
