ʻOi aku ka manaʻo o ka mana o ka hanauna hou: 18650-70C sodium-ion ʻoi aku ma mua o ka pākaukau LiFePO4 kahiko i ka hana.

ʻOi aku ka manaʻo o ka mana o ka hanauna hou: 18650-70C sodium-ion ʻoi aku ma mua o ka pākaukau LiFePO4 kahiko i ka hana.

Ma ka International Sustainable Energy Conference i mālama ʻia i kēia lā, ua ʻike nui ʻia kahi pānaʻi sodium-ion i kapa ʻia ʻo 18650-70C. ʻOi aku ka pākaukau ma mua o ka ʻenehana ʻenehana lithium iron phosphate (LiFePO4) i nā ʻāpana hana koʻikoʻi a manaʻo ʻia he holomua nui ma ke kahua o ka ikehu hou.

ʻOi aku ka maikaʻi o ka hana ʻana o nā pākahi sodium-ion ma lalo o nā kūlana wela haʻahaʻa loa. Hiki i kona wela ho'oku'u 'ia ke hiki i ka minus 40 degere Celsius, he mea kūpono ia no nā wahi anu ma mua o ka li'ili'i 30 degere Celsius o nā pila LiFePO4. ʻO ka mea ʻoi aku ka maikaʻi loa, ʻo ka nui o ka hoʻouka ʻana (3C) o kēia pākahiko sodium-ion he ʻekolu manawa ma mua o ka pā LiFePO4 (1C), a ʻo ka helu hoʻokuʻu ʻana (35C) he 35 mau manawa o ka mea hope (1C). Ma lalo o nā kūlana hoʻokuʻu puʻupuʻu kiʻekiʻe, ʻoi aku ka nui o ka hoʻokuʻu ʻana o ka pulse (70C) ma kahi o 70 mau manawa o ka pā LiFePO4 (1C), e hōʻike ana i ka hiki ke hana nui.

Eia kekahi, hiki ke hoʻokuʻu piha ʻia nā pāpaʻi sodium-ion i 0V me ka ʻole o ka hōʻino ʻana i ke ola pākaukau, he mea nui ia no ka hoʻonui ʻana i ke ola pākaukau. Ma keʻano o ka mālamaʻana i nā mea waiwai, hoʻohana ka sodium-ion i nā kumu waiwai iʻoi aku ka nui a me ka palenaʻole,ʻo ia hoʻi ma ke ao holoʻokoʻa, eʻoi aku ka maikaʻi o nā paila sodium-ion ma keʻano o ka hoʻolako a me ke kumukūʻai ma mua o nā pali LiFePO4, iʻoi aku ka palena o nā kumu waiwai lithium. Pōmaikaʻi.

I ka ʻike ʻana i ka hoʻomaikaʻi ʻana i ka hana palekana, ua haʻi ʻia kēia pākaukau he "palekana", a ʻoiai ua manaʻo nui ʻia nā pākaukau LiFePO4 ma ke ʻano he ʻano pākaukau palekana, i ka hoʻohālikelike ʻia me nā pākahi sodium-ion hou, ʻoi aku ka maikaʻi o ka maʻamau.

Hāʻawi kēia ʻenehana ʻenehana i nā hopena mana hou no nā kaʻa uila, nā polokalamu kelepona, a me nā ʻōnaehana mālama ikehu nui, a ke manaʻo ʻia nei e hoʻololi nui i ka mākeke mālama mālama honua.

Ke hoʻomau nei ka hoʻololi ʻana o ka ikehu i ka hohonu, ua wehe ʻia ka puka i nā ʻenehana pākaukau hou i kahi ʻoi aku ka maikaʻi, ʻōmaʻomaʻo, a ʻoi aku ka hoʻomau.
