E noʻonoʻo i ka haʻi ʻana o kahi psychic i kou mau mākua, i ka lā i hānau ai ʻoe, pehea ka lōʻihi o kou ola ʻana.Hiki ke ʻike like i nā mea kemika pākahiko e hoʻohana nei i nā kumu hoʻohālike hou e helu ai i ke ola o ka pākaukau ma muli o kahi pōʻai hoʻokahi o ka ʻikepili hoʻokolohua.

Ma kahi noiʻi hou, ua huli nā mea noiʻi ma ka US Department of Energy's (DOE) Argonne National Laboratory i ka mana o ka mīkini aʻo e wānana i ke ola o nā ʻano mea like ʻole.Ma ka hoʻohana ʻana i ka ʻikepili hoʻokolohua i hōʻiliʻili ʻia ma Argonne mai kahi pūʻulu o 300 mau ʻokoʻa e hōʻike ana i ʻeono mau kemika pākaukau ʻokoʻa, hiki i nā ʻepekema ke hoʻoholo pololei i ka lōʻihi o ka hoʻomau ʻana o ka pōʻai ʻokoʻa.

Ua hoʻohana nā mea noiʻi ʻo Argonne i nā hiʻohiʻona aʻo mīkini e hana i nā wānana o ke ola pōʻaiapili pākaukau no nā ʻano kemika like ʻole.(Kiʻi na Shutterstock/Sealstep.)

I loko o kahi algorithm aʻo mīkini, hoʻomaʻamaʻa nā ʻepekema i kahi papahana kamepiula e hana i nā manaʻo ma kahi pūʻulu ʻikepili mua, a laila lawe i nā mea i aʻo ʻia mai kēlā aʻo ʻana e hoʻoholo ai i kahi pūʻulu ʻikepili ʻē aʻe.

"No kēlā me kēia ʻano noi pākaukau, mai ke kelepona hele a i nā kaʻa uila a hiki i ka mālama ʻana i ka grid, he mea koʻikoʻi ke ola o ka pākaukau no kēlā me kēia mea kūʻai," wahi a Argonne computational scientist, ʻo Noah Paulson, kahi mea kākau o ka noiʻi."ʻO ke kaʻa ʻana i kahi pākaukau he mau kaukani mau manawa a hiki i ka pau ʻana e hiki ke lawe i nā makahiki;Hoʻokumu kā mākou hana i kahi ʻano kīhini hoʻāʻo computational kahi e hiki ai iā mākou ke hoʻokumu koke i ka hana ʻana o nā ʻokoʻa like ʻole.

"I kēia manawa, ʻo ke ala wale nō e loiloi ai i ka pau ʻana o ka hiki i ka pākaukau ke hoʻololi maoli i ka pākaukau," i hoʻohui ʻia ʻo Argonne electrochemist Susan "Sue" Babinec, kekahi mea kākau o ka noiʻi."He pipiʻi loa a lōʻihi ka manawa."

Wahi a Paulson, hiki ke paʻakikī ke kaʻina hana o ka hoʻokumu ʻana i ke ola pākaukau."ʻO ka ʻoiaʻiʻo, ʻaʻole mau loa nā pākaukau, a pehea ka lōʻihi o ka lōʻihi e pili ana i ke ala a mākou e hoʻohana ai iā lākou, a me kā lākou hoʻolālā a me kā lākou kemika," wahi āna."A hiki i kēia manawa, ʻaʻohe ala maikaʻi e ʻike ai i ka lōʻihi o ka lōʻihi o ka pākaukau.E makemake ana ka poʻe e ʻike i ka lōʻihi o lākou a hiki i ka wā e hoʻolilo ai lākou i ke kālā ma kahi pākaukau hou. "

ʻO kahi hiʻohiʻona kūʻokoʻa o ka haʻawina ʻo ia ka hilinaʻi ʻana i nā hana hoʻokolohua nui i hana ʻia ma Argonne ma nā ʻano mea cathode pākaukau, ʻoi aku ka patented nickel-manganese-cobalt (NMC)-cathode a Argonne."Ua loaʻa iā mākou nā pākaukau e hōʻike ana i nā kemika ʻokoʻa, he ʻano like ʻole lākou e hoʻohaʻahaʻa ai a hāʻule," wahi a Paulson."ʻO ka waiwai o kēia haʻawina ʻo ia ka hāʻawi ʻana iā mākou i nā hōʻailona e pili ana i ke ʻano o ka hana ʻana o nā ʻokoʻa."

ʻO ke aʻo hou aʻe ma kēia wahi e hiki ke alakaʻi i ka wā e hiki mai ana o nā pā lithium-ion, wahi a Paulson."ʻO kekahi o nā mea hiki iā mākou ke hana, ʻo ia ke hoʻomaʻamaʻa i ka algorithm ma kahi kemika i ʻike ʻia a hana i nā wānana ma kahi kemika ʻike ʻole ʻia," wahi āna."ʻO ka mea nui, hiki i ka algorithm ke kōkua iā mākou i ke kuhikuhi o nā mea hou a maikaʻi hoʻi e hāʻawi i nā ola lōʻihi."

Ma kēia ala, manaʻoʻiʻo ʻo Paulson hiki i ka algorithm aʻo mīkini ke hoʻolōʻihi i ka hoʻomohala ʻana a me ka hoʻāʻo ʻana i nā mea pākaukau."E ʻōlelo ʻoe he mea hou kāu, a hoʻololi ʻoe iā ia i kekahi mau manawa.Hiki iā ʻoe ke hoʻohana i kā mākou algorithm e wānana i ka lōʻihi o kona ola ʻana, a laila e hoʻoholo ai inā makemake ʻoe e hoʻomau i ka hoʻokele hoʻokolohua a ʻaʻole paha.

"Inā he mea noiʻi ʻoe i loko o kahi lab, hiki iā ʻoe ke ʻimi a hoʻāʻo i nā mea ʻē aʻe he nui i ka manawa pōkole no ka mea he ala wikiwiki kāu e loiloi ai," wahi a Babinec.

He pepa e pili ana i ka haʻawina, "Hiki i ka ʻenehana hiʻona no ke aʻo ʻana i nā mīkini ke wānana mua i ke ola ʻana o ka pākaukau, "i puka mai ma ka Feb. 25 online edition of the Journal of Power Sources.

Ma waho aʻe o Paulson a me Babinec, ʻo nā mea kākau ʻē aʻe o ka pepa ʻo Argonne's Joseph Kubal, Logan Ward, Saurabh Saxena a me Wenquan Lu.

Ua kākoʻo kālā ʻia ke aʻo ʻana e kahi Argonne Laboratory-Directed Research and Development (LDRD) hāʻawi.
