Maikaʻi nā ʻaniani asphalt, akā ʻoi aku ka maikaʻi o ke koneki / cement-ion. Kūkulu ʻia ma ke ʻano he hale kūʻai ikehu
Ma kahi o ʻelua mau makahiki i hala aku nei, ua wehewehe mākou pehea e hiki ai i ka asphalt kūlohelohe ke hoʻonui i ka mana o ka pā lithium-ion. I kēia manawa aia kahi noi no nā mea ʻē aʻe a mākou e ʻike ai i kēlā me kēia lā. Nānā nā kānaka noiʻi ma ke Kulanui o ʻenehana ʻo Chalmers ma Suedena i ka manaʻo o ka poloka ʻiʻo ma ke ʻano he pākaukau nunui. A ua loaʻa iā lākou kahi prototype o kahi pākahi cement-ion.
"ʻO ka pae pākaukau ma ka poloka he 27 pakeneka. Ke hoʻouka nei"
He mea maʻalahi ka manaʻo: e hoʻohuli kākou i nā mea a puni i mau ʻaʻa no ka mālama ʻana i ka ikehu i loko o lākou ke loaʻa iā mākou ka nui. He mea maʻalahi kēia ma mua o ka hana. No laila, ua hoʻoholo ka poʻe ʻepekema ma Chalmers University e hoʻomohala nā pūnaewele hoʻopaʻa sima. Anode Hana ʻia me ka nickel plateed carbon fiber mesh. Cathode ʻo ia ka ʻaoʻao like, akā ua uhi ʻia i ka hao. Ua hoʻokomo ʻia nā pākuʻi ʻelua i loko o kahi hui ʻana i hoʻokumu ʻia i ka sima uila i hoʻopili ʻia me nā fiber carbon pōkole hou.
Aia kekahi pūnana prototype ma ʻaneʻi a hana i loko o ka hale hana.i ke kiʻi mua, hoʻoikaika ia i ka diode (kumu). ʻAʻole ʻoi aku ka nui o ka ikehu, ʻoiai ʻo 0,0008 kWh / l (0,8 Wh / l) a i ʻole 0,007 kWh / mXNUMX.2... No ka hoʻohālikelike: Hāʻawi nā pūnaewele lithium-ion hou i mau haneli watt-hola no ka lita (Wh / l), ʻo ia hoʻi he mau haneli mau manawa. Akā, he pilikia liʻiliʻi kēia, no ka mea, ʻo nā poloka sima (paʻa) nā hale o nā haneli mau mika cubic.
ʻO ka pahu sima, i hoʻomohala ʻia e nā ʻepekema ma ke Kulanui ʻo Chalmers, he ʻumi mau manawa ʻoi aku ka ikaika ma mua o nā ʻōnaehana like ma mua. ʻO ka mea nui, hiki ke hoʻopiʻi a hoʻokuʻu ʻia i nā manawa he nui. Makaʻala ka poʻe noiʻi: ʻoiai e pili ana i nā diodes mana, nā mea ʻike liʻiliʻi a i ʻole nā pūnaewele kiaʻi kaʻa ma nā alanui a me nā alahaka. ʻAʻole naʻe lākou i ʻike i nā pilikia no ka hoʻohana ʻana i nā grids electrode i ka wā e hiki mai ana i nā hale nui, no laila e hoʻohuli iā lākou i mau mea mālama ikehu nunui.
I kēia manawa, ʻo ka paʻakikī nui loa ka hoʻolālā ʻana i nā cell i ke ʻano o ka lōʻihi e like me nā hale paʻa, ʻo ia hoʻi, ma kahi o 50-100 mau makahiki. Inā hāʻule kēia, pono e maʻalahi ka hoʻihoʻi ʻana i ka mana o ka hale ma ke ʻano he hale mālama ikehu e pono ai ka wāwahi a hoʻokomo hou ʻia.
E hoihoi paha kēia iā ʻoe:
