ʻO kahi ʻano pākahiko hou i hana ʻia mai nā polymers conductive electrically—ʻo ia hoʻi ka plastic—hiki ke kōkua i ka mālama ʻana i ka ikehu ma ka grid i ʻoi aku ka liʻiliʻi a me ka paʻa, e hiki ai ke hoʻohana nui ʻia ka mana hou.
ʻO nā pila, i hana ʻia e ka hoʻomaka ʻana ma BostonPolyJoule, hiki ke hāʻawi aku i kahi koho ʻē aʻe i emi ke kumukūʻai a lōʻihi hoʻi ke ola ma mua o nā pila lithium-ion no ka mālama ʻana i ka uila mai nā kumu hana ʻole e like me ka makani a me ka lā.
Ke hōʻike nei ka ʻoihana i kāna mau huahana mua. Ua kūkulu ʻo PolyJoule ma mua o 18,000 mau cell a ua hoʻokomo i kahi papahana hoʻāʻo liʻiliʻi me ka hoʻohana ʻana i nā mea hana makepono a loaʻa nui.
ʻO nā polymers conductive a PolyJoule e hoʻohana ai i loko o kāna mau electrodes pākahiko e pani i ka lithium a me ke kēpau i loaʻa pinepine i nā pākahiko. Ma ka hoʻohana ʻana i nā mea i hiki ke hana maʻalahi me nā kemika ʻoihana i loaʻa nui, pale aku ʻo PolyJoule i kakaomi lakoke kū nei i nā mea e like me ka lithium.
Ua hoʻomaka ʻia ʻo PolyJoule e nā polopeka MIT ʻo Tim Swager lāua ʻo Ian Hunter, nāna i ʻike he pono nā polymers conductive i kekahi mau pahu koʻikoʻi no ka mālama ʻana i ka ikehu. Hiki iā lākou ke hoʻopaʻa i ka hoʻopiʻi no ka manawa lōʻihi a hoʻopiʻi koke. He kūpono hoʻi lākou, ʻo ia hoʻi ke mālama nei lākou i kahi hapa nui o ka uila e kahe ana i loko o lākou. ʻOiai he plastic, he ʻano haʻahaʻa ke kumukūʻai o nā mea hana e hana ai a paʻa, e paʻa ana i ka pehu a me ka ʻaelike e hana ʻia ana i loko o kahi pila i ka wā e hoʻopiʻi ai a hoʻokuʻu ʻia.
ʻO kekahi hemahema nuika nui o ka ikehuʻOi aku ka nui o nā pā uila ma mua o ka ʻōnaehana lithium-ion o ka mana like, no laila ua hoʻoholo ka ʻoihana e ʻoi aku ka maikaʻi o kāna ʻenehana no nā noi paʻa e like me ka mālama ʻana i ka grid ma mua o nā mea uila a i ʻole nā kaʻa, wahi a ka Luna Nui o PolyJoule ʻo Eli Paster.
Akā, ʻaʻole e like me nā pila lithium-ion i hoʻohana ʻia no kēlā kumu i kēia manawa, ʻaʻole koi nā ʻōnaehana o PolyJoule i nā ʻōnaehana hoʻomalu mahana hana e hōʻoia ʻaʻole lākou e wela nui a puhi paha, wahi āna. "Makemake mākou e hana i kahi pila ikaika a haʻahaʻa ke kumu kūʻai e hele wale i nā wahi āpau. Hiki iā ʻoe ke hoʻohana iā ia ma nā wahi āpau a ʻaʻole pono ʻoe e hopohopo no ia mea," wahi a Paster.
Hiki i nā polymers conductive ke lilo i mea pāʻani nui i ka mālama ʻana i ka pūnaewele, akā inā paha e hana ʻia kēlā e pili paha i ka wikiwiki o kahi ʻoihana e hiki ai ke hoʻonui i kāna ʻenehana a, ʻo ka mea nui, pehea ke kumukūʻai o nā pila, wahi a Susan Babinec, nāna e alakaʻi i ka papahana mālama ikehu ma Argonne National Lab.
kekahinoiʻikuhikuhi i $20 no ka kilowatt-hola o ka mālama ʻana ma ke ʻano he pahuhopu lōʻihi e kōkua iā mākou e hōʻea i ka 100% o ka hoʻohana ʻana i ka ikehu hou. He hanana koʻikoʻi ia e hiki ai i nā koho ʻē aʻenā pila mālama pūnaeweleke kālele ʻia nei. ʻO Form Energy, ka mea e hana ana i nā pila hao-ea, wahi a hiki iā ia ke hoʻokō i kēlā pahuhopu i nā makahiki he ʻumi e hiki mai ana.
ʻAʻole hiki iā PolyJoule ke loaʻa nā kumukūʻaihaʻahaʻa kēlā, Ua ʻae ʻo Paster. Ke kuhi nei ia i kēia manawa he $65 no ka kilowatt-hola o ka mālama ʻana no kāna mau ʻōnaehana, me ka manaʻo e makemake paha nā mea kūʻai aku ʻoihana a me nā pono hana mana e uku i kēlā kumukūʻai no ka mea e lōʻihi ka lōʻihi o nā huahana a ʻoi aku ka maʻalahi a me ke kumu kūʻai ʻole o ka mālama ʻana.
A hiki i kēia manawa, wahi a Paster, ua kālele ka ʻoihana i ke kūkulu ʻana i kahi ʻenehana maʻalahi e hana. Hoʻohana ia i kahi kemika hana wai a hoʻohana i nā mīkini i loaʻa i ke kālepa e hōʻuluʻulu i kāna mau cell pila, no laila ʻaʻole pono ia i nā kūlana kūikawā i koi ʻia i kekahi manawa i ka hana ʻana i nā pila.
ʻAʻole maopopo i kēia manawa ke ʻano o ka kemika pila e lanakila ai i ka mālama ʻana i ka pūnaewele. Akā, ʻo nā palakiko o PolyJoule ke ʻano o kahi koho hou.
