E noʻonoʻo i kahi kilokilo e haʻi ana i kou mau mākua, i ka lā i hānau ʻia ai ʻoe, pehea ka lōʻihi o kou ola ʻana. Hiki ke ʻike like no nā mea kemika pila e hoʻohana nei i nā hiʻohiʻona computational hou e helu i nā ola o ka pila ma muli o kahi pōʻaiapuni hoʻokahi o ka ʻikepili hoʻokolohua.

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

Ua hoʻohana nā kānaka noiʻi ʻo Argonne i nā kumu hoʻohālike aʻo mīkini e hana i nā wānana o ke ola pōʻaiapuni pila no nā ʻano kemika like ʻole. (Kiʻi na Shutterstock/Sealstep.)

Ma kahi algorithm aʻo mīkini, hoʻomaʻamaʻa nā kānaka ʻepekema i kahi polokalamu kamepiula e hana i nā hoʻoholo ma kahi hoʻonohonoho ʻikepili mua, a laila e lawe i ka mea i aʻo ʻia mai kēlā hoʻomaʻamaʻa e hoʻoholo i kahi hoʻonohonoho ʻikepili ʻē aʻe.

"No kēlā me kēia ʻano noi pila like ʻole, mai nā kelepona paʻalima a i nā kaʻa uila a hiki i ka mālama ʻana i ka pūnaewele, he mea nui ke ola o ka pila no kēlā me kēia mea kūʻai," wahi a ka ʻepekema helu ʻo Noah Paulson, he mea kākau o ke aʻo ʻana. ​"ʻO ka hoʻololi ʻana i kahi pila i nā tausani manawa a hiki i ka hāʻule ʻana hiki ke lilo i mau makahiki; hana kā mākou hana i kahi ʻano lumi kuke hoʻāʻo helu kahi e hiki ai iā mākou ke hoʻoholo koke i ke ʻano o ka hana ʻana o nā pila like ʻole."

"I kēia manawa, ʻo ke ala wale nō e loiloi ai i ka emi ʻana o ka mana o ka pila, ʻo ia ke hoʻololi maoli i ka pila," wahi a Susan "Sue" Babinec, he loea electrochemist ʻo Argonne, kekahi mea kākau o ke aʻo ʻana. "He pipiʻi loa ia a he lōʻihi ka manawa."

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

ʻO kahi ʻano kū hoʻokahi o ke aʻo ʻana, ʻo ia ka hilinaʻi ʻana i ka hana hoʻokolohua nui i hana ʻia ma Argonne ma nā ʻano mea cathode pākahiko like ʻole, ʻoiai ka cathode i hoʻokumu ʻia me ka nickel-manganese-cobalt (NMC) i hoʻopaʻa ʻia e Argonne. ​"Loaʻa iā mākou nā pila e hōʻike ana i nā kemika like ʻole, nona nā ʻano like ʻole e hōʻino ai a hāʻule," wahi a Paulson. ​"ʻO ka waiwai o kēia aʻo ʻana, ua hāʻawi mai ia iā mākou i nā hōʻailona e hōʻike ana i ke ʻano o ka hana ʻana o nā pila like ʻole."

ʻO ke aʻo hou ʻana ma kēia wahi ka mea e hiki ai ke alakaʻi i ka wā e hiki mai ana o nā pila 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 loaʻa iā ia nā wānana ma kahi kemika i ʻike ʻole ʻia," wahi āna. ​"ʻO ke kumu, hiki i ka algorithm ke kōkua iā mākou e kuhikuhi i ke ala o nā kemika hou a hoʻomaikaʻi ʻia e hāʻawi ana i nā ola lōʻihi."

Ma kēia ʻano, manaʻoʻiʻo ʻo Paulson e hiki i ka algorithm aʻo mīkini ke hoʻolalelale i ka hoʻomohala ʻana a me ka hoʻāʻo ʻana i nā mea pila. ​"E ʻōlelo ʻoe he mea hou kāu, a hoʻopōʻaiapuni ʻoe iā ia i kekahi mau manawa. Hiki iā ʻoe ke hoʻohana i kā mākou algorithm e wānana i kona lōʻihi, a laila e hoʻoholo inā makemake ʻoe e hoʻomau i ka hoʻopōʻaiapuni ʻana ma ke ʻano hoʻokolohua a i ʻole."

"Inā he mea noiʻi ʻoe ma kahi keʻena hoʻokolohua, hiki iā ʻoe ke ʻike a hoʻāʻo i nā mea hou aku i ka manawa pōkole no ka mea he ala wikiwiki kāu e loiloi ai iā lākou," wahi a Babinec.

He pepa e pili ana i ke aʻo ʻana, ​"Ua hiki i ka ʻenekinia hiʻona no ke aʻo ʻana i ka mīkini ke wānana mua i ke ola o ka pila," i ʻike ʻia ma ka paʻi pūnaewele o Pepeluali 25 o ka Journal of Power Sources.

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

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